Forecast..Map to follow soon...

Forecast problems....Today heavy snow...Arctic air for tonight through Wednesday night...More snow for New Years Day,More cold air and more snow for Saturday...Will have more discussion on the later systems in tomorrows forecast.....

Discussion....

SFC low pressure over SD is forecasted to race into and through Central/Southern IA today..Low is forecasted to be near Chicago land by 2100 UTC...Models still showing the best lift/forcing over said areas in yesterday's forecast(read below for areas to pick up the most snowfall)...However snowfall amounts have changed...Will have a map out for them detail....Looks like Central and Northern Counties of Barron,Polk,and Rusk Counties could pick up 8 to 10 inches of snow today...Would not be shocked to see some 12 inch reports...With 4 to 8 Inches for Central and Southern areas of said Counties..In this area I would not be shocked to see a few 10 inch reports....Further South 3 to 6 inches of snow looks to be on the docket....Winds will be on the increase for today as pressure gradients increase between the low and high pressure of to our Northwest...This will add more headaches for the plow crews today,as blowing and drifting snow will become a problem....
See map for the details on snowfall amount....
Tonight the low pressure pulls far enough way,takes the snow and clouds with it...Temps will take a hit tonight...Should easily drop close to -10 if clouds clear out soon enough....Wednesday a break in the action,however it shall be a cold day with temps struggling to get out of the single digits....Wednesday night clouds increase we should see temps slowly raise over night as WAA slowly kick in...Thursday another system is forecasted to move into and through the area...Thinking at this point in time the accumulating snows will hang to the Northern parts of my FA...More on this tomorrow....Need to put more time on this winter storm effecting the area today....
Forecast issued @ 5:08 AM
