A Punch of Cold to Come!

(Thursday, January 1, 2009) – We were warmer than the average first day of the new year with highs today into the lower 50s in many areas.   After a mild few days, models are in general agreement that that is going to change next week.  A colder weather trend will be with us until about the middle of the month when the pattern will relax.  Below is a look at how the pattern will evolve:

Upper Level Pattern – Valid 6P 01 Jan

Upper Level Pattern – Valid 6A 04 Jan

Upper Level Pattern – Valid 6A 06 Jan

Upper Level Pattern – Valid 6P 09 Jan

Upper Level Pattern – Valid 6P 11 Jan

Upper Level Pattern – Valid 6P 16 Jan

The pattern shows how we begin with a zonal or flat upper level flow and it will amplify by first of the week.  We’re in a northwest flow through about the middle of the month when we begin to see more Pacific air flood the country.  This upcoming cold pattern will likely make the news.  Recall that models struggle with getting a handle on the intensity of the low-level cold until it is right upon us.  We’ll probably see the long range temps groomed downward as time goes on.  It’ll be fun to watch.  Snow geese, there’s still hope!!
