Forecast for Western and Northwestern WI

Forecast problems...Fog this morning...Then rain chances from Wednesday through Sunday....Then temps become a problem next weekend....

CURRENT CONDITIONS....

Tempsat the 6 AM hr for the most part are in the upper 40s to lower 50s across the FA.Areas of fog also a problem early this morning...Some of it is quite dense..Not a widespread fog,nonetheless one should be albe to run into a thick fog bank from time to time..This will be lifting over the next hr or so.Winds rather calm at this hr....

SFC/UPPER LEVEL ANALYSIS.....

500 MB charts showing large upper level ridge in place across the FA,as been the case for the last several days...Upper level low way down in Central IL won't have any effect of the FA....SFC charts showing SFC low/trof over Southeastern MO..This will not be effecting the FA....SFC CDFNT confined to Canada just North of the MN border....This front should be pushing Northwards as a WRMFNT..Mean time we also find a FNTL BNDRY over Eastern MT reaching back into ID...This will prove to be our next weather maker....

TODAY THROUGH TUESDAY NIGHT.....

FA still locked under a large upper level ridge..This will insure the FA MSTLY sunny skies today....Areas of fog should burn off rather fast after sunrise..Southerly winds will also help to lift the fog out..Temps today should range from the middle 70s North to around 80 South....Lows tonight fall back into the 50s....Tuseday same conditons will apply areas of fog in the early morning hrs then MSTLY suuny skies the rest of the day...Highs will be same o same...

WEDNESDAY THROUGH FRIDAY....

CLDFNT starts to work Eastwards through MN by 12z Wed this frontal BNDRY should be getting closer to knocking on our door step...This will help draw more moisture into the area,as of now INSTBY looks rather weak,nevertheless should be enough for thunderstorms....As far as strong to severe thunderstorms goes...Looks slim as cloud cover will hold INSTBY in check....Highs willbe cooler middle 70s seem plausable with clouds/rain/storms around...Lows in the middle 50s should work out fine...Thur & Fri will hange onto to a slight chance of showers,maybe a thunderstorm or two on Thur...Highs both days around the middle 70s lows in the 50s....

SATURDAY THROUGH SUNDAY....

500 mb charts showing an upper level low/closed off low pressure dropping out of Canada...This is FCSTD to make camp over the FA....This will set the stage for off and on rain showers and temps falling back to below norms once again....Highs middle 60s Central and South..Lower 60s North....Models have been showing this warmer than the last few runs...So with any luck by time we reach the weekend we can be talking about temps in the 70s....Ok a little wishcasting going on there....This cold dome should last right into early the following week....
