The forecast for Western/Northwestern WI....

Warm temps still camping out over the FA..This trend should hold through much of the upcoming work week....Temps should start to trend down wards as we get towards the end of next week...Next chance of rain comes back into play towards the Thursday night/Friday time frame...More on this in a few...


***CURRENT CONDITIONS***

Temps this morning are in the middle to upper 40s under cloudy/foggy skies..Warmest temp is found in Eau Claire 48°,while the coolest temp is found up in Ashland 44°...VSB from fog range from 1/4 mile to around a mile in some of the thicker fog....

***SFC ANALYSIS***

This morning SFC Charts shows a 1004 MB low pressure system over Eastern MN/Western WI....With a cold front reaching North and South from said low..Meanwhile a week area of high pressure is center over ND and another area over Eastern WY...A cold front is located from Western MT back towards Northern CA...We find a very strong 998 MB low pressure off the NC Coast...This could lead to some forecast issues.....Low pressure over our neck of the woods is forecasted to lift Northeast and weaken during the day...This should bring the end to rain through out the area as the day flies by....1027 MB high pressure out over the Western states is forecasted to start to slowly push towards the area...By Sunday this high should be located in Western MT and should be around 1037 MBS.....Ridge of 1037 high pressure will build into the area and should keep our skies mostly sunny to sunny through much of the new work week...Can you say blocking pattern...That is what appears to be taking shape...Some in part is do to the low out over the Eastern Coastal areas...As it will just meander around for a few days...

***SFC/MID/ UPPER LEVEL DISCUSSION***

Main story here is the upper level blocking pattern setting up...Models are not really seeing eye to eye on this...However Am going to run with GFS has it has been more bullheaded about this all week...ECMWF has been all over the place,so not much weight given into ECMWF model ATTM....This will allow for much of the Western/Central US to be dry and warm..Our upper level winds will be Westerly so not much cooling of the column...So temps should be at or above norms must of the new work week.....Upper level low is forecasted to to move Southeast into the Rockies then out into KS,then towards the FA by Thursday night into Friday this will bring in a slight chance of rain by this time frame...Will have to see how strong and how long the blocking pattern will hold...May have to pull rain chances out of the forecast
