Your local forecast

Forecast problems...There are a few of them...1...Thunderstorms this afternoon how strong will they be?...2....Will frost become a bigger problem than forecasted for Monday night?.....Last but surely not least....Will the temps warm up by weeks end?....
Current Conditions.
Temps this morning have a wide spread to them....Middle to upper 30s along the North shore into far Northeastern tip of MN....Middle 40s to lower 50s are found else whereas....Also some areas of fog in the SCF reports this morning....Radar is showing a line of showers maybe a thunderstorm or two from Lake County all the way down into Benton County MN the line becomes broken more as it reaches into Kandiyoki/Meeker Counties..The highest DBZ I found so far is around 40 45 at best..This where one may hear a clap of thunder or two...This cell was ready to move into Benton County...
Today and Tonight.
A cold front now starting to works it's way into the Western parts of our MN FA is forecasted to keep on the pace and should be into far Eastern MN and Far Western parts of WI FA by midday...Showers and thunderstorms have been firing along and just ahead of said front....Except this trend to be ongoing for most of the day...Some of the models are saying that some of these thunderstorms could become strong this afternoon...Though the boundary layer is some what on the dry side...How lapse rates are rather steep...Given the cold temps aloft and near the SFC..Any thunderstorms that may become strong could produce some hail along with gusty winds later today...I did not ad strong wording into the forecast as I feel this will not be a widespread event,scattered at best,if that...Tonight the front clears the FA however will keep a few showers alive as a weak shortwave moves through...
Monday and Monday night.
Shortwave still hangs around much of the day.So kept some showers in the forecast...That very well might have to be changed later today....System moves out of the FA Monday later afternoon this will set the stage for clearing skies, and light winds as a rather strong high pressure builds into the area..Radiational cooling will take hold Monday night this setup is some what like we saw back on August 25/26....However this setup we may have a few more clouds around to keep this from going into a widespread freeze event....Patchy frost does look like a good bet..I have added that into the forecast...We will have to watch this, as this could turn into more of widespread event if less clouds hang around....
Tuesday.
As of right now looks to be a dry day temps still on the cool side,however a little warmer...
Wednesday and Thursday..
Next system moves into the area during this time frame.It appears right now this system will have better moisture to work with and should bring the FA a good amount of much needed rain...We shall see....
