Forecast(AFD)

Note...1.50 Inches so far at the Weather Center still snowing rather hard at this hour..Should not really see much more than 2.00 inches for totals

Forecast problems....How far to bring the snow North today,and how much more snow will fall over our Southern Counties of WI,Barron,Polk,Rusk,along with possible LES for Ashland,and Iron Counties....

CURRENT CONDITIONS...

Radar is showing light snow/flurries through out my Southern zones of WI into a small part of my Southern MN zones a Heavier band of snow has set up over Northern Barron,and Polk Counties along with the Southern parts of Burnett,and Washburn Counites into Sawyer County...Temps in the lower 30s through much of my Central and Southern areas...While in my Northern areas of MN temps in the lower 20 to middle 20s.....Skies for the most part are cloudy with some Northern areas of MN reporting clear skies at this hour...

SFC ANALYSIS....

999 MB low pressure centered over SW IA this morning some what weaker than models had it yesterday.Which is also nicely seen on all the satellite imagery....Strong 1038 MB Arctic high pressure over Canada's mid section.....

TODAY THROUGH MONDAY NIGHT.....

999 MB low pressure is forecasted to move into Northern MO/far Southern IA by 12z today..Said low is forecasted to trek through said areas and move onto the door step of IL by 18z today...Then off to the Northeast towards NY areas by 00z Tuesday...As said low makes to trip across said areas it is forecasted to pull down a few shortwaves out of Canada so flurries up in out Northern areas of MN possible Monday,and Monday night...Down through our Central and Southern zones of WI light snow is possible through out the day and tonight....Main areas to see snow would be Barron,Polk,Rusk,and parts of Sawyer Counties...Here there has been a range of .50 to 1.50 of snow over the last 8 hours....Not looking for much more in them areas maybe another .25 to .50 if we are lucky.....Strong 1038 MB high pressure builds into the upper mid-west pressure gradients between the low and high increase so winds will be kicking up out of the North..Not as bad as we were forecasting yesterday...Still could see gust in the 20 to 25 MPH...Still not to thrilled about LES accumulations attm...However there will be a rather good amount of fetch of the Lake,still other indicators aren't point to big event attm...We will watch this and see how it unfolds through out the day....

TUESDAY THROUGH MONDAY....

Still held onto LES/rain for Ashland,and Iron Counties for Tuesday into part of Wed...Other than that looks to be a rather quiet period...Temps start the new work well below norms,however the good news is they do moderate back to the norms by the end of the work week into the weekend...Should remain dry into much of the weekend..With warm temps..More clouds on Sun as a low pressure system moves towards the area....Mon..I did bring in some rain showers and thunderstorms......

LONGER TERM FORECAST....(TUE APR 14 THROUGH TUE APR 21)

Tuesday Low pressure is forecasted to move over my WI FA..This will allow for rain showers may also may mix snow from time to time by Tuesday afternoon...System still holds onto my Eastern MN and all of my WI areas so rain/snow still possible..Models have really backed down from the big warm that was forecasted yesterday.So yesterday's long term forecast needs to be updated to account for this.Highs still look to be in the middle to upper 40s for the most part ...Models showing 50s by Sat the 18....With lows in the middle to upper 20s still ruling the FA..upper 40s to lower 50s look good for the rest of this time frame...Lets go back and talk about precip through the rest of this time frame.......Looks like another shot of precip moving back into the for this weekend......
