The forecast for Western & Northwestern WI.

Looks like a great weekend for any outdoor activity one has planed…Will be less humid and cooler…Temps do moderate back into the 80s the start of the new work week through midweek…Then cool right back off at the end of the week temps may not even get out of the 60s by Friday….There will be periods of off and on showers and thunderstorms…


***CURRENT CONDITIONS***

At the 9 AM hour skies are sunny to partly cloudy throughout the FA…Temps are in the middle to upper 60s with a few stations reporting 70.Winds are calm to light from the West/Northwest..Dewpoints in the middle to upper 50s with a few low 60s..Either way its less humid.

***FORECAST DISCUSSION***

Looking at the latest SFC charts we find the cold front that pushed through the area in now about to enter Eastern WI…Meanwhile a secondary cold front is entering ND…This cold front should be knocking on our door right around 18z today….Cold front is not forecasted to push through the FA to around 06z Sunday…Front will come through dry…Front washes out over central WI and MN, as a 1024 MB high pressure system builds into the area…This setting the stage for a very nice weekend one we haven’t see in a very long time….Sunday night a warm front starts to work back into the area…We could see a few showers and thunderstorms along and just North of this front…This will allow for very warm and humid conditions to return to the area…Monday warm front rather close to the area so showers and thunderstorms will be possible some storms Monday into Monday evening could become strong to severe….Tuesday warm front blasts through the area will be a very warm and humid day…Wednesday we have the warm front North of the area with a 1004 MB low pressure system moving through Northern MN with a cold front extending South of low through Western MN…Temps on Tuesday and Wednesday should hold like they were yesterday…Middle 80s to upper 80s…Once again ATTM thinking is 90s will be found out over Eastern MN and in my far Southern zones…This time 90s could even get into my far Western Counties near the MN boarder..e will have to watch this as there are some indications that a good chunk of the FA could see their 90 degree reading of the year for now will not add 90s into the forecast will wait for a few more computer runs to decide… Wednesday late afternoon into the overnight time frame the strong cold front is forecasted to work Eastwards into the FA…This could set the stages for showers and thunderstorms...However just like yesterday capping does look to be a problem as 700 MB temps forecasted to be 12c + Cap does weaken by 0z Thursday, however there is still some questions to rather the cold front will have pushed through by then…Something we will work out as we get closer to that time frame… After that temp really take a hit downwards highs may only reach the upper 60s by Friday…

Hitting back on Monday’s severe weather possibilities…CAPE does increase to around 1500 to 2500 J/KG Lifted Index runs around -4 to -6… As of right now Shear is around 20 to 25 KTS so looks like a small chance at severe weather.. Also this activity will be elevated so look for mainly hailers if this were to pan out….

***LONG TERM FORECAST DISCUSSION JUNE 7TH THROUGH JUNE 20TH.***

To sum this time frame up looks to be on the wet side with off and on showers and thunderstorms….Temps will have a wide range through this period ranging from the lower 70s to middle 80s with lows ranging from the lower 50s to around 70… Once the long term models start to agree better we will go more into details, right now it all depends what model one looks at….What I did was blend them together for this summary…..
