Now for the forecast

Forecast headaches...Today...Cold temps..Tonight frost....Tuesday through Wednesday thunderstorms....

CURRENT CONDITIONS....

Temps starting this Mother's day in the upper 30s to lower 40s..Still some rain showers showing up on radar in parts of my WI zones...Most of my Northern and Western MN zones under fair to PTLY CDLY skies....

SFC ANALYSIS....

This morning's weather charts showing a 1018 Low pressure system sitting over SW WI..A 1026 high pressure system over Central Southern ND/Central Northern SD...Meanwhile a 1022 MB high pressure is over NE/MO Then that pesky FNTL BNDRY over the far Southern States...This is where all the active weather will remain...Severe thunderstorms again a good PSBLTY along the boundary areas.....

TODAY THROUGH MONDAY....

Weak area of low pressure that has and still is kicking off some showers over mainly my WI Counties is FCSTD to move out of the area today...High pressure is FCSTD to build into the area,this is already showing up rather nice on the satellite image...This should end the rain across my WI zones,however skies here should remain MSTLY CDLY...In most of my MN zones skies should be PTLY CDLY...Highs today will be well below norms for this time of year....Tonight temps will dive into the 20s and 30s across much of the FA,this with PTLY CDLY skies and light winds could lead to the formation of frost across the entire FA..
Monday FA area under the hands of a high pressure system....Mon may be a little of a problem...WAA slowly kicks into gear if this happens a little sooner may have to add a chance of showers and thunderstorms in the FCST...For now am going to keep it dry....

MONDAY NIGHT THROUGH WEDNESDAY.....

Monday night WAA gets it act going on stage so will run with chances of showers and storms..Best chance coming over my Western and Central areas of MN...Tue and Wed....Strong CDFNT moves into and through the area...Showers and thunderstorms look to be a sure bet...PWS still FCSTD to range around the 1.25 Inches...Still not to thrilled about a lot of INSTBY,however with forcing along and ahead of the strong CDFNT could see some thunderstorms become strong...SEE HWD for that info....

REST OF THE WORK WEEK....

Thur..should be dry...Did run with showers and storms for Friday,as WAA kicks back into play....

THE LONG TERM....

Off and on showers and storms are in much of this time frame...Temps for the most part will remain on the cool side,still should see a few warm days here and there...
