The New Abnormal
Residents of Brimson, Minnesota, just inland from Two Harbors, woke up to a jaw-dropping low of 30F Wednesday morning - chilliest reading in the lower 48 states. A week from now Brimson and much of Minnesota will see highs near 90F. Remarkable.
We've always been pushed around by cold fronts and heat spikes but the last few years have brought even steeper curves on a global temperature roller coaster ride. The greater the temperature swings the higher the potential for memorable storms.
Former Energy Secretary Bill Richardson writes "Since 2011 the USA has experienced 25 extreme weather events that each caused more than $1 billion in damages. These events contributed to the loss of more than 1,000 lives and each American family paying $400 more per year".
A symptom of more heat and energy in the system? Probably.
Wave goodbye to the Dog Days of September; we heat up into the 80s this weekend - 90F possible early next week as dew points climb into the mid 60s, up in the oh-zone. Most of us won't see T-storms until next Wednesday. No frost, hail or hurricanes either.
We're watching the tropics; there's a risk that "Erin" may become a hurricane and track toward New Orleans.

Summer, The Sequel. Here's European data, courtesy of WeatherSpark, showing a gradual warming trend into next week, highs topping 90 next Thursday and Friday as dew points rise into the mid and upper 60s. The only significant chance of showers and T-storms: next Wednesday. (top data plot: temperature; bottom plot: dew point).
Warming Trend Central USA. The 84 hour NAM model shows a retreating high pressure bubble turning on more of a southerly breeze from Kansas City to the Twin Cities, meaning a slow warm-up into the weekend. Heavy showers and T-storms linger along a stalled front draped over the Southeast, while "Erin" crosses the Yucatan Peninsula, pushing into the Gulf of Mexico. Loop: NOAA.
Flash Flood Potential. The 5-Day rainfall prediction from NOAA HPC shows some 5-6" amounts from near Pensacola to Augusta and Charleston, meaning more flash flooding over the Southeast. If "Erin" does push toward Louisiana or Alabama some towns could see in excess of 10-15" rain in the next week.
Growing Tropical Storm - Hurricane Potential. Here's an excerpt of an Alerts Broadcaster briefing that went out to our corporate clients Wednesday morning:
Potential for a tropical storm or hurricane rises in the Gulf of Mexico. It's still too early for specifics regarding timing, track and intensity, but facilities and staff from Florida to Texas should be on a heightened state of alert. But it's not too early to take early precautions from Brownsville and Corpus Christi to Houston, New Orleans, Mobile and Pensacola.
An Early Look At "Erin"? The tropical wave on the latest visible satellite is still disorganized, but conditions over the Gulf of Mexico remain favorable for strengthening later this week (little wind shear aloft, warming water temperatures), and there is now a strong likelihood that this disturbance will strengthen into Tropical Storm Erin by Saturday.
Heating Up In The Tropics. NOAA NHC now believes there is a 50% risk that the disturbance south of Cuba will strengthen to tropical storm force in the coming days, up from 10% Tuesday morning. There's an even higher probability (60%) that a tropical wave just off the coast of Africa will become a tropical storm. We are heading into a much busier cycle for tropical storm and hurricane potential in the coming weeks. (note: as of late last night the probability of tropical storm formation in the Gulf of Mexico over the next 48 hours has risen to 70%)
Mitigating Factor. Water temperatures in the western Gulf of Mexico are unusually warm, as high as 84-88 F, the rough meteorological equivalent of bathwater. The warmer the water, the greater the potential for intensification. This is why a more westward track is problematic, hinting at a stronger tropical storm or hurricane by early next week.
Worst Case Scenario. Here's the solution that has me tossing and turning in my sleep, one I'm not buying just yet. The Canadian GEM model, which was the first to hint at a significant storm in the Gulf of Mexico yesterday, is bringing a Category 3+ hurricane into coastal Texas by Tuesday of next week. My confidence level is still very low that this precise track/intensity will become reality, but we can't entirely dismiss this solution. We receive 4 model updates/day, and we run our own internal models, searching for continuity and alignment between models, and searching for trends from run to run. This is why it's important that staff remain alert and begin reviewing hurricane protocols, especially from Brownsville and Corpus Christi to New Orleans and Mobile.
Latest (12z Wednesday) model runs increase the potential for a tropical storm or hurricane to impact the Gulf Coast this weekend. The most reliable model (HWRF) brings a minimal, Category 1 hurricane into New Orleans and Mobile, but confidence levels on this track are still low, a 2 out of 10. The previous run of the HWRF suggested a possible Texas landfall early next week, so even the most accurate/reliable models are still highly erratic. That said, we are encouraging our clients with Gulf Coast exposure to review hurricane response plans and prepare to activate those plans within 24-48 hours.
Latest Forecast Track. The 12z run of NOAA's HWRF model brings "Erin" near Cancun, before strengthening over the Gulf of Mexico Thursday and Friday, with a potential track toward New Orleans, Mobile, even Pensacola. Again, track confidence levels are still low: a 2 on a scale from 1-10. Keep in mind the greatest wind/water damage occurs to the right (east) of where the center of the storm comes ashore.
Potential For Intensification to Hurricane Strength. The same HWRF model shows Erin coming ashore as a minimal, Category 1 hurricane within 84-96 hours. The big unknown: how unusually warm (84-87 F) water temperatures in the Gulf of Mexico may impact intensification. It's still too early for specificity. If Erin arrives as Category 1 storm it would generate a 4-7 foot storm surge, capable of moderate to significant coastal flooding and beach erosion, especially if the storm comes ashore close to high tide.
Midnight Saturday Night. Here is a breakout of expected wind speeds (upper left), central pressure (lower left), simulated clouds (upper right) and future radar (lower right) from the HWRF model, valid around midnight Saturday night. The latest solutions shows the highest winds (gusts over 100 mph) impacting the Mississippi Delta of Louisiana, but sparing metro New Orleans. The big unknown is storm surge potential, but if Erin does come ashore as a Category 1-2 hurricane the retrofitted levees surrounding New Orleans should hold. Coastal flooding might be more significant from Bay St. Louis and Gulfport to Biloxi, Pascagoula and Mobile, as much as 4-8 feet above normal high tide.
Significant Flood Potential. Models print out a swath of 4-8"+ rain from near New Orleans, Mobile and Pensacola well inland to Birmingham, Atlanta and the Carolinas. Locally, as much as 10-16" of rain may fall if "Erin" takes the track shown above. Moderate storm surge/wind damage is possible, but as is always the case with tropical storms and hurricanes, the greatest impact may come 1-2 days after landfall, in the form of excessive rains and severe inland flooding.
Lingering Flash Flood Potential. Regardless of where Erin comes ashore, the southeastern USA will see soaking rains from a stalled frontal boundary, with T-storms redeveloping along that front, producing some 4-7"+ rains over the next 7 days. Facilities and staff from Mobile and Pensacola to Macon, Augusta, Columbia, Savannah, Hilton Head, Charleston and Wilmington should be prepared for a significant risk of urban and river flooding in the days to come.
Summary: latest models increase the possibility of a more northerly track across the Gulf of Mexico. It's still too early to pin down final track, intensity and implications with any level of confidence, but facilities on or near the Gulf of Mexico should be in a heightened state of alert, with possible impacts as early as Saturday. We'll keep you posted.
Fire Whirls: A Tornado-like Sign Of An Extreme Wildfire. You thought a tornado was scary? How 'bout a tornado composed of fire and smoke? Here's an excerpt of a remarkable story at The Salt Lake Tribune: "Consuming as many as 15 homes, it seemed the rapidly moving Rockport 5 Fire that forced evacuations in Summit County Tuesday couldn’t get any worse. Then people started seeing something else: giant funnel clouds of fire and smoke rising out from the depths of the flames. They’re called fire whirls, and they’re a sign that the fire is taking control. The whirls happen when extreme heat meets high winds within a very healthy wildfire. The two forces combine to form small whirls that consume smoke and even flames, according to Monica Traphagan of the National Weather Service in Salt Lake City. "You’re seeing a fire sort of create its own weather," Traphagan said..."

The fire is across the road from Lake Rockport Estates, which runs adjacent to State Road 32 near hamlets of Coalville and Wanship. Residents there were ordered to evacuate Tuesday, August 13, 2013."
Shocking New Footage Of Japan Tsunami. This video clip runs 25 minutes, but it's one of the more amazing things I've ever seen, from a little ripple of water coming up the river to chunks of the town sweeping past at 30-40 mph minutes later. This captures the slow-motion horror of a tsunami better than anything I've ever witnessed. Here's a link to the video and explanation from wtop.com: "It can be hard to fathom the sheer power of mother nature. A horrifying video has emerged capturing the Japan tsunami from the moment the water begins to rise. The video, which appeared on RedFlagNews.com, shows how quickly conditions can change."
Why Blackouts Are Becoming More Common, In Two Charts. The Washington Post is running the story - here's the introduction: "The Department of Energy has a new report (pdf) out taking a look at the vulnerability of the U.S. power grid to blackouts. One notable fact: Outages caused by severe weather have become much more common over the past decade. Power outages of all sorts are becoming more frequent since 1992, but the real action has come from weather-related outages. The report notes that “thunderstorms, hurricanes and blizzards account for 58 percent of outages observed since 2002 and 87 percent of outages affecting 50,000 or more customers.” (The rest are caused by things like “operational failures, equipment malfunctions, circuit overloads, vehicle accidents, fuel supply deficiencies and load shedding — which occurs when the grid is intentionally shut down to contain the spread of an ongoing power outage.”)...
Invasive Ants: "Stowaway" Insects Spreading Around World. The BBC has the story; here's the introduction: "A Spanish team of scientists has found that larger than expected numbers of the insects are being unwittingly shipped around the world. The researchers warn that many of these species are establishing colonies in their new habitats that could pose a threat to the environment, infrastructure and human health. The research is published in the journal Royal Society Biology Letters. Lead author Veronica Miravete, from the University of Gerona in Spain, said: "Due to their small size, most ants are transported involuntarily in containers and other boxes, together with soil, wood, ornamental plants and fruits etc, on ships or airplanes..."

Smartphone Batteries Used To Determine Weather Conditions. Here's a novel application - now we're all potential walking, talking (mobile) weather observations. Here's an excerpt from Gizmag: "Smartphone batteries contain tiny temperature sensors, designed to keep the phone from overheating. While those sensors do measure the heat generated within the phone, their readings are also affected by the temperature of the phone’s external environment. With that in mind, British app developer OpenSignal has created a system that allows multiple users’ phones to provide real-time, location-specific weather reports. The system is based around the company's existing OpenSignal app, which was designed to collect data sent voluntarily from users’ Android phones in order to create maps of Wi-Fi access points and phone coverage..."

Tents Get Wired For Taking Technology Camping. Kind of defeats the purpose of "camping", but who am I to judge? Gizmag.com has details; here's an excerpt: "There are those for whom ditching the modern comforts of home and roughing it is one of the main attractions of camping. For such people, the traditional tent will likely do. But there is another breed of campers that can’t stand to be separated from their technology, be it digital music, videos, tablet computers, drink blenders, etc. For them, there's a new generation of high-tech tents wired to power all the latest portable gadgetry..."

The Complexities Of Climate Change. Here's an excerpt of a story at The Atlantic and Mother Jones: "If we're to avoid destructive climate fluctuations, scientists say we need to slow, and eventually halt, the emission of greenhouse gases that do and will continue to produce global warming. A big chunk of our emissions come from the consumption of the fossil fuels -- the coal, oil and gas that remain a crucial part of keeping the modern economy running. Not an easy task. Let's look at which fuels, and countries, produce the highest levels of carbon dioxide pollution, and how we can try to rein these emissions in. In the United States green advocates are concerned about the climate impacts of all manner of new fossil fuel developments, but there is one culprit that stands above the rest. Potential emissions from increased oil production, more shale gas drilling, new pipelines, and exotic fuels pale in comparison to the possible carbon impact from coal reserves..."

Anyway, a democratic public does not want bare facts. It wants meaning. It wants to know why climate science matters and what can be done about it. More fundamentally, it’s not just that people want meaning, it’s that they only absorb facts through meaning. Our identities are how we make sense of information. This is the whole point of cultural cognition research: We seek out information that reinforces our identities..."
requires much bigger and far more intrusive government than mitigation. Indeed, if the anti-science ideologues continue to stop serious mitigation, then the government will inevitably get into the business of telling people where they can and can’t live (can’t let people keep rebuilding in the ever-spreading flood plains or the ever-enlarging areas threatened by sea level rise and Dust-Bowlification) and how they can live (sharp water curtailment in the SW Dust Bowl, for instance) and possibly what they can eat. Conservative opposition to serious climate action now will force big government in coming decades to triage our major coastal cities — Key West and Galveston and probably New Orleans would be unsavable, but what about Miami and Houston? (See Don’t believe in global warming? That’s not very conservative.)..."I have made a different argument: If you hate government intrusion into people’s lives, you’d better stop catastrophic global warming, because nothing drives a country more towards activist government than scarcity and deprivation.

Unicorns Doled Out For Climate Change Deniers. Here's a clip from a story at CNN: "As part of their push to promote President Barack Obama's climate change agenda, the political group formed from his presidential campaign is going after Republican lawmakers who have expressed skepticism of climate change. The group sent a message on Twitter Tuesday with a photo of a "climate denier award" trophy, topped by a unicorn. The group's volunteers are delivering the statues to lawmakers Tuesday..."
