No-Weather-Drama Thanksgiving Week (details on major east coast storm)

Posted by: Paul Douglas Updated: November 25, 2013 - 10:12 PM

Cold and Quiet

"Too cold to snow?" Not exactly, but when temperatures are in the teens it often means the storm track, the main superhighway for heavy rain, ice and snow, has been pushed well south of Minnesota.

A well-advertised nor'easter will spread heavy rain and snow right up the east coast today and Wednesday, complicating travel plans. I expect 2-3 inch rains east of I-95, with local flooding. Well inland over the Appalachians some 1-2 foot snows are possible.

1 in 3 Thanksgivings have at least an inch of snow on the ground here in the Twin Cities, but this will not be one of those years. Lake effect snows kick in downwind of the Great Lakes but I expect a brown Thanksgiving. Dry weather spills over into next weekend with slowly moderating temperatures; low 30s returning by the weekend.

Big storms will continue to detour well south of Minnesota into early December, but at some point steering winds will buckle, and we'll see just the right mixture of cold air and moisture for snow.

Keep an eye on mid-December. Last year over 10 inches fell on December 9. Over 17 inches fell on December 10-11, 2010. Will history repeat itself in 2013?

I'm still betting on a very white Christmas.


45 Day Wish-Cast. No, this isn't a forecast, more like a horoscope, but I thought snow-lovers would find this vaguely amusing. NOAA's CFS (Climate Forecast System) shows a couple inches of snow around December 4, snow on the ground increasing to 6" by the second and third week of December, implying a (very) white Christmas. Don't bet the farm on a 45 day "trend", but let's see how this works out.


Stormier Pattern For Central USA? Just about the time I was ready to totally dismiss the 45 day trend, I got a look at 500 mb winds averaged between December 1 and 5, showing a developing trough of low pressure over the Rockies and Plains, a "storm incubator". With enough cold air in place and moisture bubbling out of the Gulf of Mexico, the planets might just align for a better chance of accumulating snow within 2 weeks.


Major Storm Brewing For The Busiest Travel Day Of The Year. Great timing huh? An estimated 80-100 million Americans will feel the effects of this storm, the same system that spanked the Deep South with snow, ice and rain, now spreading a shield of heavy rain up the East Coast. Today's Climate Matters is focused on what is top-of-mind: will I be able to reach my Thanksgiving destination? "WeatherNationTV Chief Meteorologist Paul Douglas shows the possibility of a major storm to affect the busiest travel day of the year. And just what has Thanksgiving had in store for major cities across the US?"


Northeast Warnings. NOAA has issued a High Wind Watch from metro New York City and Long Island to Hartford and Boston, for winds gusting in excess of 40 mph at times. Winter Storm Warnings include Rochester, Buffalo and Pittsburgh, where a healthy coating of white is likely by Wednesday night. A Winter Storm Watch is posted for the western suburbs of D.C. and Baltimore for a few inches of slush. No significant snow is expected east of I-95. For the latest warnings and advisories from Ham Weather click here.


Mid Atlantic Warnings. As of late last night Ice Storm Warnings were posted near Asheville, North Carolina, a Winter Storm Watch for the hills of northern Georgia, and from the western Carolinas into much of the Virginias and western Maryland. Latest warnings from NOAA and Ham Weather here.


East Coast Storm Details. Here's an excerpt of an earlier Alerts Broadcaster briefing:

* Much-advertised storm still on track to soak the East Coast today into Wednesday; significant risk of flash flooding and urban flooding.

* Heavy rain event along and east of I-95; 1-4" snowfall between I-95 and I-81 - potential for a very heavy wet snow over higher elevations from northern Georgia and the Carolinas into the Virginias, central and western Pennsylvania, upstate New York and interior New England.

* Heaviest rain and snow pushes out to sea in time for Thanksgiving.


Timing The Storm. For the southeast today will be the wettest day, a shield of moderate to heavy rain with embedded T-storms from Huntsville to Atlanta, reaching Charlotte and Raleigh by afternoon. The greatest risk of localized flash flooding will come this afternoon into Tuesday night, especially in poor drainage areas and regions that often flood during major storms. ECMWF (European) model map above valid midday tomorrow. Map: WSI.


Wednesday Morning: Storm Peaks Mid Atlantic & Northeast. The map above verifies at 6 AM Wednesday, what promises to be a horrific travel and commuting day from Richmond and Washington D.C. to New York and Boston. Expect wind-driven rain, heavy much of the morning and midday, tapering late Wednesday as cold winds kick in on the backside of this intense storm. Rain will end as a period of wet snow from Roanoke and the western suburbs of Washington D.C. to Harrisburg, Allentown and western New Jersey. ECMWF guidance: WSI.


Soaking, Potentially Flooding Rains. Models have been consistent in printing out excessive amounts of water with this storm, fueled with moisture from the Gulf of Mexico and the Atlantic. I still see a swath of 2-4" rains from Atlanta and Charlotte to Washington D.C., Philadephia and New York City, most of that falling late Tuesday into Wednesday morning. NOAA guidance (above) is even hinting at some 5" amounts from the hills of northern Georgia to the suburbs of New York City - capable of initiating street and small stream flooding.


Flash Flood Thresholds. The map above shows how much rain has to fall to initiate flash flooding; some 3-4" for much of the southeast, but closer to 2-3" for the Carolinas. This is why we're concerned about the risk of urban and small stream flooding. Flash flood guidance courtesy of NOAA.


Lower Flash Flood Thresholds Northeast. Because the ground is partially frozen much of the rain that falls will run off into streets and streams late Tuesday into Wednesday, increasing the potential for flash flooding, especially D.C. and Baltimore into New York City. In New York the threshold for flash flooding is closer to 2"; models print out close to 4" of rain for the Big Apple.


Heavy Snow Potential. A light (nuisance) accumulation of slush is possible generally west of I-95, most of that coming at the tail-end of the storm Wednesday into Wednesday night. West of I-81 amounts will be more significant, probably "plowable". Some 12-20" amounts are predicted from Virginia's Shenandoah into central and western Pennsylvania and New York. NAM snowfall totals above: NOAA and Ham Weather.


Summary: The timing isn't great, coming during the most-traveled week of the year for for the USA. The same storm system that has been tormenting the southern Rockies and southern Plains with snow and ice will track up the east coast Tuesday and Wednesday, providing a 1-2 punch of heavy rain and mountain snows. The good news (which is hard to find this morning): right now I don't see any widespread severe storm outbreak or enhanced risk of tornadoes in the warm sector of this storm - and beach erosion from the Outer Banks to Long Island and Cape Cod should be minor to moderate. Tuesday looks like the worst day for the Southeast; Wednesday will be the peak-trouble day for the Mid Atlantic and New England region with significant impact on travel by air and land. Expect delays and impacts to facilities, staff and customers.


Future Radar. NOAA's 4km NAM model shows precipitation starting out as a wintry mix, then quickly changing to (heavy) rain for the eastern seaboard, with a changeover back to snow (from west to east) across the Appalachians Wednesday as colder air pushes in on the backside of today's intense coastal storm. The storm will push out to sea in time for Thanksgiving. Animation: Ham Weather.


Chilly, But Quiet. Dry weather persists into the weekend; great news for travel within 300 miles of MSP. Today will be the coldest day, highs flirting with 20F, the wind making it feel like single digits. Temperatures moderate slightly by the end of the week; the next chance of light snow coming Monday, again Wednesday of next week. Graph: Weatherspark.


Ouch. Long-range GFS model guidance shows a wintry swipe after December 5. The models have been fairly consistent from run to run, which increases our confidence level that this (arctic) front is real. We may go the better part of 5 days with highs in single digits to low teens, nights dipping below zero. Lovely.


Typhoon Haiyan: How A Catastrophe Unfolded. Here is one of the more comprehensive, well-researched stories I've read on why the recent tragedy in the Philippines was far worse than even the most pessimistic outlook; an excerpt and video from The Wall Street Journal: "...Some officials miscalculated the biggest threat that Typhoon Haiyan posed to the city and its surroundings. They used a term for the storm that wasn't widely understood. They grossly underestimated the havoc the storm would wreak, stocking far too few supplies for a city to survive on in an emergency. And they failed, despite vigorous efforts, to move many of the most vulnerable people out of harm's way. For almost 24 hours, local and national officials in Tacloban had no way even to call for help. They had simply failed to imagine a storm so large. That failure of imagination, combined with residents' skepticism that the storm would be worse than any of the other 20 or so that lashed the scattered archipelago every year, had a deadly and devastating impact..."


TV Is Dying, And Here Are The Stats The Prove It. We're all hard-wired to want to watch narratives with interesting storylines and compelling characters (that applies to sports as well). But will we be watching "TV" or videos on our mobile devices, streaming them to our monitors when we're home? I'm a little skeptical of pundits predicting the end (of anything). Newspapers were supposed to die 10-15 years ago, and yet most have found ways to innovate and reinvent. The same thing may happen with traditional TV, although cable providers have their work cut out for them, as outlined in this comprehensive story at Business Insider. Here's an excerpt: "...We're at the beginning of a major historical shift from watching TV to watching video — including TV shows and movies — on the internet or on mobile devices. This is going to hurt cable TV providers. Nearly 5 million cable TV subscribers have gone elsewhere in the last five years. The number of cable TV-only subscribers remaining could sink below 40 million later this year, according to this data from ISI Group, an equity research firm (at right)...."

Canadians Rescue Shark Choking On Moose. This may be my favorite headline of the week, and it could only happen in Canada (or maybe a remote stretch of northern Alaska). Here's a clip from Outside Magazine: "Two men pulled off what was perhaps the most Canadian animal rescue mission of all time this week when they saved a large Greenland shark from choking to death on a moose. Derrick Chaulk was driving along the coast near Norris Arm North in Newfoundland when he spotted what he believed to be a beached whale. The beached whale turned out to be a shark with a big hunk of moose hide hanging out of its mouth..."


Two Concussions Turned This Student Athlete Into A Musican Prodigy. So you're telling me...I have a shot at greatness! Just when you think you've heard everything there is to hear, along comes this story and video from Time Magazine - here's a clip: "...But doctors say that Lachlan’s head injuries, which barred him from playing contact sports again, rewired his brain. So while he had to ditch football and lacrosse,  Lachlan found out that he could play 10-13 instruments by ear with ease. Including two types of bagpipes. Because just one is for musical hacks.."


How To Cook Your Holiday Turkey In The Dishwasher. Because you're too lazy or inept to use an oven? O.K. My second-favorite headline of the week, courtesy of the L.A. Times: "If you can't seem to keep your Thanksgiving turkey moist in the oven, you may want to try your dishwasher. Yes, people have been using the kitchen washing machine to cook proteins and fish since the 1970s, but famed chef David Burke insists you can also use it to cook the star of your Thanksgiving meal.  But before you start shoving your entire turkey in the dishwasher, Burke's recipe calls for two boneless turkey breasts, not the entire bird. The meat and herbs are packed tightly in plastic wrap then sealed in Tupperware containers before hitting the top shelf of the dishwasher for three cycles or about 3 hours and 25 minutes..."

40 F. high in the Twin Cities Monday.

36 F. average high on November 25.

30 F. high on November 25, 2012.

Trace of rain and snow reported at MSP International yesterday.

Minnesota Weather History on November 25 (courtesy of the Twin Cities National Weather Service):

2001: A strong low pressure system developed in Colorado on the 25th, reached eastern Iowa during the evening of the 26th, then moved into eastern Wisconsin late on the 27th. It produced a wide swath of heavy snow across much of central Minnesota into West Central Wisconsin. Storm total snowfall of 8 inches or more was common, with a large area exceeding 20 inches. Specifically, Willmar picked up 30.4 inches, New London saw 28.5 inches, Collegeville had 23.4 inches, Litchfield and Granite Falls received 22 inches, 14 inches at Canby, 10.7 inches at Springfield, 11 inches at Long Prairie, 12.5 inches at New Hope, 15 inches at Milaca, 11 inches at Wild River State Park, and Milan had 20 inches. A convective snow band set up across this area on the 27th and remained nearly stationary for over 12 hours, resulting in the extreme storm totals. From 8 am on the 26th to 8 am on the 27th, Willmar received 21 of its 30.4 inches, setting a record for most snowfall in Willmar in a 24 hour period. Visibilities were frequently below 1/4 mile during the storm, and winds remained in the 15 to 30 mph category. The heavy wet snow downed numerous power lines, and at one point, at least 20,000 customers were without power in the Minneapolis-St. Paul metropolitan area. Over one thousand traffic accidents were noted across the entire area. Most were minor, but one accident claimed two lives when a car spun out and collided with a semi near Mora.

1995: A narrow band of five to eight inches of snow fell from west central Minnesota around Canby and Granite Falls to east central Minnesota. This included much of the Twin Cities metro area.

1965: Snowstorm across northern Minnesota. 14.7 inches of snow fell at Duluth, and 13.6 inches at Grand Rapids.

1896: Severe Thanksgiving day ice storm over southwest and central Minnesota. 1.42 inches of rain at Bird Island and 1.20 inches of rain at Montevideo. The ice caused a great deal of damage to trees and shrubs.

Climate Stories...

New Widget Counts Global Warming - Happening At 4 Hiroshima Atomic Bombs Per Second. Here's a clip from a story at The Guardian: "Global warming is accumulating in the Earth's climate system at a rate equivalent to about 4 Hiroshima atomic bomb detonations, 2 Hurricane Sandys, or 4 magnitude 6.0 earthquakes per second. The amount of energy building up on Earth due to human-caused global warming can be difficult to picture. 250 trillion Joules per second sounds like a lot, but what does that mean in terms people can more easily visualize? This widget, created by Bob Lacatena at Skeptical Science, tries to do just that. The widget can be installed on most blogs and is customizable, allowing users to choose the color, size, button style, and starting year. For example, since 1998, the Earth's climate has accumulated over 2 billion Hiroshima atomic bombs worth of energy..."


Warsaw Climate Change Talks End On A Blurry Note. Let's kick the can down the road a few more years. Here's a summary of what happened (and did not happen) at the latest international climate change talks in Warsaw, courtesy of Politico: "After tense eleventh-hour negotiations, delegates at international climate talks in Warsaw, Poland, could agree to only a broad set of terms aimed at setting world nations on a path toward a 2015 global warming accord while avoiding the troublesome specifics for now. The U.S. and other countries agreed Saturday that, by early 2015, they will put forward their individual plans for lowering emissions, a move that gives nations less than a year to review the plans before key December 2015 talks in Paris. But negotiators in Warsaw failed to agree on key details, such as what the plans should include and how they should be evaluated..."

Analysis: U.S. Air Pollution Authority Faces Supreme Court Tests. Here's an excerpt from a good summary of what's at stake from Reuters: "The U.S. government's authority to regulate air pollution nationwide, often against the wishes of Republican-leaning states, could face new curbs when the Supreme Court takes on two high-stakes cases in coming months. The cases focus on the broad-ranging power wielded by the Environmental Protection Agency (EPA) under the landmark Clean Air Act, first enacted in 1970. The law was envisioned as a cooperative effort between the federal government and states in which the EPA sets standards but states have to set plans to comply. That flexibility has allowed states which favor looser regulations, like Texas and Kansas, to resist - with the support of industry groups like the U.S. Chamber of Commerce and the National Association of Manufacturers - when the agency wants to impose more stringent standards..."

Tired Of Negativity? Here's a clip from an Op-Ed at Huffington Post that resonated: "...Large-scale solutions to large-scale problems: the key to optimism, hope and resilience. That's what I'm going to carry in my heart over the next year as I write to you about air pollution and our changing climate. Optimism comes from health leaders, creative thinkers and innovative leaders in the business, technology and engineering community. And from political leaders willing to speak the truth in dark times. Optimism comes from our own thoughtful friends and neighbors who are mindful of resources, living by some pretty old-fashioned values: stewardship; respect. Optimism comes from those whose moral compass is pointing true north -- where a love of the world resides."
