Forecast dis. for Northwestern/Western WI


Forecast problems…..Once again tomorrow there will a chance of isolated to scattered showers and thunderstorms around….Better chance tomorrow night as WAA kicks in full gear….Temps will be somewhat problematic for the weekend, more on this later…..

CURRENT CONDITIONS……

At 11:00PM skies range from clear to partly cloudy…..Temps are in the upper 50s to lowers 60s….. Winds are calm ti light from the East/Northeast….

*** FORECAST DISCUSSION ***

Look for the same setup tomorrow as we have seen over the last few days…..A few showers and thunderstorms will be possible in the afternoon…..Tomorrow night a shortwave is forecasted to move into Northern MN….WAA will kick into high gear this will aid in more showers and thunderstorms Thursday night into the early morning hours of Friday… Shortwave will still hang around for Friday afternoon….Here is where things could get a little interesting…..Depending if storms get going in MN and if they can hold their own, which ATTM conditions looks like they could/should……This storms could effect parts of my Central and Northern areas….Some of these storms could be on the strong side to even lower end severe…..Still feel the main severe weather threat should stay over in Central and Northern MN for Friday afternoon……Highs on Friday should flirt with 80…….Saturday and Sunday…. We will see tons of sunshine……No  showers or storms are forecasted, as the atmosphere will be capped due to very warm temps aloft…..850 MB temps 15 to 20c will mean a hot two days on tap…..Temps will reach for the 90 degree mark this weekend…If we get some high to middle clouds to drift in temps will them be in the upper 80s….Dewpoints are forecasted to be in the 60s….So looks like a great weekend on or in the lakes…..

Sunday night a cold front is forecasted to march across MN…This will fire off thunderstorms…..Storms should form into a line…..This line of storms should march its way through my FA Sunday night into the early Monday morning hours……Can’t rule out a few strong to severe thunderstorms…..Though with the frontal boundary forecasted to come through after prime-time SFC heating is over….Monday afternoon could be interesting as  another cold front/ Shortwave drops Southeast into the area……We could see a better chance of severe thunderstorms then, however thermodynamics look a tad weak ATTM….Something we will keep a close eye on though….

*** MIDDLE TERM FORECAST DISCUSSION***

Tuesday will be colder than normal with highs in the upper 60s to lower 70s…..Same holds for Wednesday and Friday. There will a chance of a few showers and thunderstorms for Wednesday….Overall the big weather story will be the colder temps and lower dewpoints….Which will be welcomed after this weekend….

***LONG TERM FORECAST DISCUSSION***

We will issue this tomorrow……
