Subzero Air Roughly Two Weeks Away
<p id="1duct0">Snowbirds are missing all the fun! While cold weather refugees in Arizona and Florida pick sand out from between their toes, Minnesotans are playing in powder, enjoying 20s and 30s and light winds, with nary a storm in sight.</p>
<p id="7Itwjc">As a rule our coldest days tend to be sunny, and having blue sky overhead is a coping skill for many of us. Character-building attributes may be put to the test in 2 weeks, when the first blistering shot of arctic air reaches Minnesota. The last 7-10 days of January may be Nanook, with a streak of subzero nights, even a daytime highs below zero as well with dangerous wind chills. It's too early for details but battery-draining air may envelope Minnesota and much of the USA by the last week of January.</p>
<p id="y3E1vz">Today's short-term forecast challenge is clouds and fog. Unusually light winds (for January) favor ice fog every night. A weak sun may be unable to burn away clouds into the weekend.</p>
<p id="ueMUOt">Mild weather lingers into next week - then the bubble bursts, as we welcome a shot of polar air.</p>
<p id="MdE6Br"><strong>Forecast Wildcard: Fog</strong>. With winds about as light as I can recall in early January any fog and low stratus clouds that form overnight may be impossible to burn away later this week, keeping daytime temperatures cooler than they would be otherwise, with a strong inversion trapping chillier air near the ground. Even with the inversion I expect temperatures a few degrees above average.</p>
<p id="nFlnVj"><strong>Numbing End to January?</strong> Models (especially NOAA's GFS guidance) are consistent in bringing much colder air into Minnesota and much of the eastern USA within 2 weeks or so. GFS may be overdoing the cold (high of -29F on January 22?) but the trends are undeniable; subzero weather is coming.</p>
<p id="xG5koD"><strong>Cold Enough</strong>. Record-breaking cold? Too early to tell, but there's now little doubt that we will be shivering through roughly the last 8-10 days of January. How long this cold phase hangs on into February is very much up in the air.</p>
<p id="DlBRrH"><strong>The Polar Vortex is Splitting in Two, Which May Lead to Weeks of Wild Winter Weather. </strong>Especially on the East Coast and New England, I might add. Capital Weather Gang has a good explainer: "<em>A dramatic spike in temperatures is occurring at high altitudes above the North Pole, where the air is thin and typically frigid. Known as a sudden stratospheric warming event, experts say it's likely to have potentially significant repercussions for winter weather across the Northern Hemisphere for weeks to possibly months. This unusually strong event may have profound influences on the weather in the United States and Europe, possibly increasing the potential for paralyzing snowstorms and punishing blasts of Arctic air, with the odds of the most severe cold outbreaks highest in Northern Europe.</em>.."</p>

La Niña means cooler Pacific water temperatures, which in turn reduces upper-level winds that "basically tear apart" Atlantic storms. But even if a season has more storms and stronger storms, he said, "We can't say where the storms are going to go…it's all about location, location, location</em>..."</p>
