Forecast problems...Short term today through Sunday...Fog this morning...Mid term....Sunday night through Tuesday....Frz rain,rain,than wintry mix,than light snow...

CURRENT CONDITIONS.....

Skies across the range from clear to cloudy,with fog being reported through out much of the FA..Temps starting out rather warm this morning upper 20s to middle 30s across much of the area..Radar showing some returns nothing to get excited about though.Main story is the fog some has been dense..This should be the trend through the early morning hours...

SFC ANALYSIS.....

WV satellite showing a nice spin over central WI this morning..This low pressure has brought in the mixed precip over night...This low is more to the East than the current computer analysis shows Cold front has pushed through much of MN and into most of our WI forecast area......

TODAY THROUGH SUNDAY...

Rather peaceful weekend on tap for much of the forecast area...I may have to add more cloud cover to my far Northern areas of MN with some light snow as a another cold front drops South...As of right now banking on weak area of high pressure/weak ridge to build in sooner than models are forecasting...Fog this morning should burn off rather fast,however points in WI may be dealing with fog into the early afternoon hours..Highs both day will be a little cooler,however still rather nice..Winds this weekend shall be rather light compared to yesterday.....The calm before the storm...

SUNDAY NIGHT THROUGH TUESDAY....

Here is where things get a little complicated....GFS,and NAM for the most agree on the track of the low pressure strength is some what close also...Both Models take the low out of OK/TX panhandle and push it into Northeastern MN through this time Frame....ECMWF has the low a tad more to the East,However this should not play havoc on the forecast...The way thing as setting up at the SFC and the upper level thermal dynamics looks like we may be dealing with an ice storm for much of our FA Sunday night into Monday morning...This mainly appears to be in MY MN FA...Will have to watch our WI zones as this will be a close call for them,as FRZ rain will start Early Monday morning..Should change over to plain rain by time the afternoon rolls along...MN areas will see FRZ rain last longer...Models QPF showing .25 inches of ice could accumulate....For now will hold off on HWD....As this storm system is still in the forming stages,though all models do seem to have a good handle on it.....My Southern zones of MN, and WI may very well see their first thunderstorms of the year will be talking more in detail about this in tomorrow's update...That will depend if we can get the dry slot to work up into them areas....This storm system may also be effect by a severe thunderstorm outbreak over the Southern plans..If this does happen this should limit the amount of moisture flowing North into the FA,We will have to watch that real close as this could very well have impact on this system....

WEDNESDAY THROUGH FRIDAY....

Another strong area of Low pressure is forecasted to move Northeast,this low as of right now should not effect the FA as it will remain well South of the area...Will talk about in tomorrow's update....

LONGER TERM FORECAST.....

Sorry long term forecast will not be issued today as we have to much going on with this possible ice storm....
