The forecast for Western/Northwestern WI and thunderstorm outlook.

Enjoy today’s warm weather a big changes on tap, even a chance of snow…Good news is it does warm backup a little by week’s end with a chance of showers and thunderstorms, none of the thunderstorms are forecasted to be severe.

All stations reporting sunny to mostly sunny skies...Temps are in the upper 40 to lower 50s...Winds are light out of the West/Southwest


High pressure system will remain parked over the area today…Will run with temps a little warmer than yesterday…999 MB low pressure if forecasted to start to lift Northeast into MO later today..This low is forecasted to deepen to 992 MBS as it pushes into Southern WI/Northern IL by later tonight or early Tuesday morning… This low will hang around throughout Wednesday, meantime we see an upper level low pressure system moving into the MN then into WI…At this time it does not appear that the upper level and SFC low will become vertical stack…. Look for rain to form very early Tuesday….Rain will be likely Tuesday and could be heavy at times….Models painting out ½” to ¾” inches…Winds will also become a problem as they howl out of the Northeast could gust up to 30 MPH….Colder air gets drawn into the system so rain Tuesday night is forecasted to mix with and chance over to all snow….This will also hold for Wednesday morning into early afternoon…. We could see 1 to 3 inches of snow by time the snow changes back to rain and slowly ends….

Will run with a dry forecast for Thursday however will keep clouds around…..Friday looks like the second nicest day of the this week with partly cloudy skies….Saturday another system works into the area so showers and thunderstorm are forecasted.. Will keep rain in the forecast right through Sunday morning until the strong cold front moves through.


The early morning hr of May second still should see some rain will also be mixed with snow As a Low up by Hudson Bay keeps drawing in colder air and wrap around moisture…We will hold on to rain and snow mix right through the early morning hr of Tuesday may 3rd… High pressure builds into the area on the 3rd so we should see skies become partly cloudy…Temps should be right around 50..Next system moves into the area on the early morning hrs of Wednesday the 4th this will bring a chance of rain back into the area..Once again we could see a rain snow mix during the overnight hrs of Wednesday into early Thursday morning hrs..We get a break on Friday May 6th …By Saturday morning May 7th more rain is back in the forecast. This hold right through Sunday May 8th and Monday May 9th Again with the 540 dropping South we could see another round of rain snow mix in the overnight hrs and early morning hr of the 9th and 10th.Tuesday the rain should end by early afternoon….

So over all highs in the upper 40s to middle 50s with a day or two around 60, but temps will average out to well below normal through this time frame…..Precip should average out above normal….People are already calling this “the year without spring” so far that is living up to the name…..
