Get Ready To Bundle Up! Cold Blast This Week
Have you gotten your parka out of the closet yet this winter? If not, you may want to find it - and fast!
Saturday saw daytime highs only in the teens here in the Twin Cities, the coldest high we've seen so far this season. The previous coldest had been 20 on Friday. However, we are going to wish for highs in the teens and 20s by the middle of next week.
After a snowy Sunday, with weekend total snow accumulations of 4"+ in the Twin Cities, an Arctic front will slide through the region during the beginning of the week. This will help push south the coldest air we've seen so far this season across the upper Midwest. Highs later this week will only be in the single digits above zero in the Twin Cities, and likely not make it above zero at times across northern Minnesota. We'll also see our first subzero lows since mid-February.
There are also signs that we could see an additional push of cold air next weekend, extending the bitter cold into the week leading up to Christmas. It looks like winter has finally arrived in Minnesota.

Minnesota Weather Outlook
Snow will be lingering across Minnesota as we head into Sunday across the region, with highs in the mid/upper 20s across the Twin Cities. Highs will only be in the teens across northern Minnesota.
Here's the forecast for the Twin Cities Sunday. Highs will be around average for this time of the year, with winds out of the east.
Snow totals across southern Minnesota will be in the 4-8" range, with totals approaching 4-6" across the Twin Cities. This is TOTAL snow between Saturday and Sunday, not a Sunday-only total.
Because of the snow expected, Winter Weather Advisories (in purple) are in effect for southern Minnesota through Sunday evening, including here in the Twin Cities.
After the snow... here comes the cold. These are highs for Wednesday across Minnesota - parts of central and southern Minnesota will barely make it into the single digits above zero during the day. Meanwhile, across much of northern Minnesota, highs will remain below zero.
You can see the nose dive we take in temperatures by the middle of next week. Make sure you enjoy the near-average day Sunday while it lasts! Another little warm up is currently pegged in the models for late this week/early next weekend, before another cold blast works in for the beginning of the week right before Christmas. The good news, looking long-long term, is that the models are hinting at another warm up in time for Christmas. Only time will tell.
National Weather Outlook
84 Hour Forecast
As we head through Sunday and into early next week, a snowstorm that will bring areas like Chicago, Milwaukee and Detroit the potential of at least six inches of snow will be moving east. Places like Boston and New York City could pick up a few inches of snow Sunday Night into Monday morning before changing over to rain. Another batch of light snow could be possible across the Great Lakes early next week, followed by more lake effect snow toward the middle and end of the week. Out west, a stream of moisture will be flowing onshore across northern California and into Nevada and Utah by Tuesday, and continue through the middle of the week. Significant mountain snow will be possible.
Heavy Snow Through Monday Plains To Northeast
Starting with the event ongoing Sunday and into Monday from the Midwest to Great Lakes, a long duration snow will finally come to an end Sunday evening across areas such as Chicago, Milwaukee and the Twin Cities. The system will continue to head east Sunday Night into Monday, bringing with it some accumulating snow across the Northeast, including the potential of a few inches of snow in Boston and New York City before changing over to rain during the day Monday. Here's a look at expected overall snow totals for the Milwaukee, Chicago, Detroit, Boston and New York City metros:
Milwaukee Area Forecast:
Chicago Area Forecast:
Detroit Area Forecast:
Boston Area Forecast:
New York City Area Forecast:
Snow Potential Over The Next 10 Days
After this snowstorm moves through the Northeast, another batch of snow will move through early in the week, bringing with it some light snow totals across the upper Midwest and Great Lakes. After that, with the cold air in place, the lake effect machine will start up once again during the middle of the week, bringing heavy snow to the favored Great Lakes snowbelts. Significant western mountain snow will be possible into the middle of next week from California to Colorado and Wyoming with a moist Pacific plume. The models are hinting at another storm system late next week which could bring another shovelable/plowable snow to parts of the Midwest.
Five Day Precipitation Outlook
Parts of the Great Lakes could pick up over an inch of moisture through Thursday, mainly coming in the form of snow. Meanwhile, parts of the eastern U.S. could pick up over an inch of much needed precipitation. Heavy amounts of precipitation are also expected out west, with the potential of a few inches of rain for the Bay Area and (once again) heavy mountain snow.
Ready For Winter To Settle In?
The coldest air of the season (at least so far) is getting ready to plunge south as we head into the work week behind an Arctic front. This will bring temperatures that are a good 10-25 degrees or greater below average to parts of the upper Midwest by Tuesday and Wednesday. This animation above shows 850 mb temperature anomalies from Sunday, December 11th through Saturday, December 17th, with a large batch of colder than average air moving into the upper Midwest, then eventually toward the east coast.
Bitterly Cold Highs Wednesday
These are actual forecast HIGHS for Wednesday across the upper Midwest. Parts of Minnesota and North Dakota will not make it above zero for the entire day. Meanwhile, temperatures will struggle to reach the teens in Milwaukee and Chicago, where they should have a nice layer of snow on the ground by them helping to keep temperatures cooler.
Departure From Average Temperatures Wednesday
Highs Wednesday will be a good 10-25 degrees below average for this time of year as far south as northern Texas, Oklahoma and Arkansas. This cold weather will continue to push east toward the end of the week.
Forecast Wind Chills Late This Week
Brrr! This chart shows the coldest wind chill expected between the 15th and 19th of this month (in the dashed lines) as well as where that ranks vs. climatology this time of year (in the shading). Minimum wind chills for that time period will be far below the climatological average - even in the 90th percentile as far south as Dallas.
Coldest Wind Chills
With the upcoming cold, the Iowa Environmental Mesonet put together this map of "the temperature at which we'd expect to see 12 hours of wind chill at that level or colder" during the selected months. Even as far south as northern Texas we can see wind chills dip into the single digits below zero during the coldest parts of the winter. Read more about this map from the IEM by clicking here.
Another Cold Blast The Week Before Christmas?
There are hints in the models that another cold blast could work south out of Canada just in time for next weekend and the week before Christmas, plunging temperatures once again across a good portion of the country. We will have to keep our eye on this as we head through the next few days... and to see how long it will last.
It’s the weekend, and I know you want to relax. So why not watch a couple clouds crash into each other? This is part of Mitchell F. Chan’s new art piece which you can view in person in Toronto, but only until January 7th. Find out more in this Gizmodo article written by Andrew Liszewski.
Zigzagging Smoke Over Australia
I always find it interesting what we can see on satellite. This picture above (courtesy of NASA) shows the Cocklebiddy fire on December 7th across western Australia. You can see the smoke plume zigzagging across the region. This fire did shut down the Eyre Highway for a time. Click to read more from NASA about this image.
A Gym Built To Withstand A Tsunami
One day a tsunami will hit the Pacific Northwest. It’s bound to happen. Westport, WA has taken some steps in order to prepare for one by building an elementary gymnasium that can protect 1,000 people. WIRED has a fascinating story on how they decided to build the structure – and still make it look friendly to elementary school kids: “We tried to employ anything we could to make it more relatable to an elementary school student who is four feet tall,” says Brian Ho, associate at TCF Architecture. That’s no mean feat for a structure surrounded by steel columns, clad in concrete masonry and metal walls, topped by a six-inch-thick steel-and-concrete roof, and anchored by concrete piles that extend 55-feet into the sandy earth.”
Another Warm Month Across The County
Are we done sweltering yet? 2016 saw the second warmest November on record for the lower 48, with three states seeing their warmest November on record (Washington, Idaho and North Dakota). Meanwhile, 20 long term NWS climate locations saw their warmest November on record, and 154 total sites saw a top ten warmest. Click to read more from AerisWeather.
Boston Preparing For Climate Change
On Thursday, the City of Boston released a comprehensive study on how climate change would affect the city, including proposed solutions on how to adapt to our ever changing climate. The report states that Boston has seen 21 events since 1991 that were declared either federal or state disasters, and that the number of events are likely to increase in the future. You can read the whole report on the Climate Ready Boston website.
Clean Energy To Make Your iPhone?
Your next iPhone (okay… maybe your second or third next iPhone) could be at least partially made with wind power. AppleInsider has an article stating that Apple has signed a deal to bring clean wind power to its Chinese suppliers. This is a change for Apple, who has primarily relied on solar power in the past for clean power. More from the AppleInsider article: “The (South China Morning) Post didn't indicate which Apple suppliers would benefit from the arrangement, or how much power Apple is hoping to supply. Recently, however, Lens Technology said it would fully power its glass production with renewable sources by the end of 2018, doing so partly through wind farms in Hunan province.”
