Forecast for Western & Northwestern WI

***SEVERE THUNDERSTORMS & HEAVY RAINFALL***


***CURRENT CONDITIONS***

At this 9 am hr temps through out the FA are in the upper 50s to lower 60s... Cold spot is up in Superior with a temp of 48 warm spot is over in Osceola temp of 63... Dewpoints have came up during the over night hrs....Upper 50s to lower 60s Winds still remain out out of the East/Southeast from 7 to 17 MPH with some gusts up to 26 MPH...Radar showing the thunderstorm complex slowly moving out of the area...Back edge now extends from Northeast Polk County through Central Barron, Dunn, and Pepin Counties.. I would expect in a hr or 2 this area of showers and thunderstorms should clear must of the FA all for my far Northeastern parts... Satellite imagery still showing a large area of clouds back through MN....

***FORECAST DISCUSSION***

Low pressure is forecasted to move East through the area today...Moisture flowing Northwards along with cape around 500 to close to 1500 J/KG....Dewpoints should keep their upward trend into the 60s.... Warm front to the South will try to work Northeast not having much luck... More thunderstorms should fire along said front... Though support appears to be in place thinking is clouds will keep SFC heating at bay, hence lowering the chances of severe thunderstorms... With that said, any thunderstorms that form on either side of the warm front will need to be watched rather close for large hail and damaging winds...Main tornado threat will be South of warm front in the warm sector where wind shear is the greatest.ATTM I'm not really thrilled about severe thunderstorms in my FA.. Heavy rain still looks to be the main problem today and through this evening....1 to 2 inches of rain is forecasted so flooding is still a concern... Sat will still have to keep a chance of showers and storms as the system will still be rather close to the FA...Sunday is looking like the best day...Monday should also be dry...After that more showers and storms.... with temps close to normal..

***TODAY THROUGH TONIGHT***

Showers and thunderstorms reforming some of the thunderstorms could produce heavy rain, some hail along with gusty winds this afternoon & evening... Highs around 70 winds South/Southeast 10 to 15 MPH with higher gust in and near thunderstorms...Low tonight fall back into the upper 50s....

***SATURDAY THROUGH SATURDAY NIGHT***

Will keep a chance of showers and thunderstorms going with highs around 70 and lows in the middle 50s.. Winds East to Northeast around 10 MPH...

***SUNDAY THROUGH SUNDAY NIGHT***

Skies become PC with a North/Northwest wind around 5 to 10 MPH.. Highs lower to middle 70s with lows in the middle 50s...
