2024 Ends Warm, Arctic Cold Coming In Surges.

 A weak front has staggered off the LA/MS coasts bringing drier air for tonight's New Year's celebration.  Some cooler air arrives for Wednesday, but it's not the real cool down coming for next week.  IF models are correct, a huge dip in the upper air pattern will bring down Arctic air that could bring us freezing temps in the 5-10 day time frame.  I grabbed this graphic off of Zack Fradella's morning weather program.



That can't happen until the East Coast upper trough returns.  Right now the pattern has a mainly west to east upper flow over the southern states.  Even though we'll be cooler for the next several days, it's not the Arctic blast coming after Jan. 6-7th.   Here's the GFS computer forecast showing why the chill will drop out of Canada.  We begin with today's flow with a small dip over Illinois.



That dip lifts into the main vortex over eastern Canada by Saturday with generally a NW flow over us.


Fast forward to next Friday and see how the upper trough deepens allowing a north to south flow into the U.S. That flow continues through the following week the this graphic valid for Jan. 16th.


That's 2 weeks out, and we know from the uncertainty of Tropical systems at 10-14 days, a lot could change.  But IF the computer is correct, look how cold it's getting up in Canada & Alaska.



We have no freeze threats in the short term and will have all weekend to watch whether we'll need to protect our plants for the following week..  For now, let's enjoy the New Year.





There is some cooler air coming in from the NW, but it is much drier too as dew points fall into the 30s.



You'll notice a different feel to the air later this evening as the northerly winds increase.  IF you're dressed for it, it will feel great!  Note the huge Arctic Blast coming for NEXT week.  Freezes probable, snow not likely, but there's always hope when it gets cold enough.  Stay tuned!
