The forecast..Looks warm with off and showers and storms..

Forecast problems....Still a small chance of showers today then a chance of showers and thunderstorms Friday,and Friday night...Still will hold on to scattered showers for Saturday....Temps may be on the tricky side,but overall should hold right around 70 from today through Saturday.....

CURRENT CONDITIONS....

Looking at the SFC OBS across the area...Temps in the lower to middle 50s through out the area under cloudy skies....Dewpoints range from the upper 40s to lower 50s.....Radar at this 8 AM hr showing a band of showers from Central and Eastern Washburn County through Central and Eastern Barron County....Reaching into Dunn and Chippewa Counties...Sawyer and Rusk Counties have some rain showers per radar...This activity should clear the area within the next hour or so..Satellite showing the clearing line now moving into parts of Western WI...



SFC ANALYSIS..

This morning's SFC charts still showing that old stationary frontal boundary from OK Panhandle up through PA...Shortwaves have been traversing this frontal boundary since last week...That trend still not giving up...1017 MB high pressure is sitting over the Northern high plains reaching up into Canada...Also we find a shortwave Through MN

TODAY THROUGH SATURDAY NIGHT.....

Frontal boundary will be pushed to the way to South into TX,AR,TN,SC by Saturday...Shortwave is moving through MN pushing into WI this morning...Evident on the satellite and radar showing so showers along it boundary..Nice clearing line showing up through Central MN..Update to show clearing line now pushing into Western WI.....This is were temps could become tricky....If clouds clear out temps should have no problem ramping up a few degrees warmer than now forecasted...Looking at the satellite loop I see no reason why we won't see more sun today that the past 5- 6 days...Will keep a chance of showers in the forecast for this morning...Then skies should become partly cloudy...Still some lower level moisture being trapped so with some SFC heating this afternoon.Clouds could reform with some ISO light showers....We shall see....Tonight lows throttle back into the into the middle 40s....Friday is a whole new headache as models mainly the GFS/NAM showing their own outcome for Friday....So what I did I used the good old trusty ECMWF, and blended GFS with it...Trof of low pressure is forecasted to move through the area...This should bring us a chance of showers and thunderstorms Friday afternoon through out the over night hours of Friday...Thinking is as of now Southern MN into my Central and Southern FA have the best chance at seeing this activity.None of the thunderstorms are forecasted to be strong or severe..Highs on your last day of work should push into the lower to middle 70s...Lows on Friday night right around the 50 degree mark...Saturday will hold onto the chance of some light rain showers...Don't feel ATTM Saturday will be wash out...Highs will be right around 70 with the clouds and ISO showers around...Saturday night lows drop to around 50 once again under mostly cloudy skies...May see some clearing later Sat night...

SUNDAY THROUGH WEDNESDAY....

Sunday and Monday look to be dry and warmer...Temps on Sunday reach for the middle 70s with lows in the lower 50s..Monday we should break the 80 degree mark under mostly sunny skies...Monday night lows in the middle 50s look good to run with..Dewpoints will be coming back up..So things will start to get muggy..A word we haven't used that often this spring...
Tuesday and Wednesday...Next system starts to roll into and through the FA...This will bring the chances of showers and thunderstorms back into the forecast...Some of these storms could become strong to severe both days...Still ways out in time to try to forecast that,nevertheless models are point their fingerer at it..So we will watch to see how this unfolds...Temps will still be in the upper 70s to lower 80s with lows in the middle to upper 50s.....So one is asking how long will this warm air stay around for ? Answer below.....

LONGER TERM.... (JUNE 18 THROUGH JUNE 27).....

We should get a break in the showers and thunderstorms on Thursday....Friday we see yet another system moving into the FA with another round of showers and thunderstorms...It appears right now there is going to be a frontal boundary setting up very close to home..With systems riding along this...So rounds of showers and thunderstorms will be the main story right through next weekend into Monday...Cold front is forecasted to move through the area on Monday this will leave us high and dry for Tuesday....By Wednesday we see another system diving Southwards out of Canada,so will be forced into adding showers and thunderstorms back into the forecast for Wednesday afternoon through Friday....So to sum the precip dept up...Looks like we will be in for an active period....Time to talk about the temps dept....Temps start the period rather warm middle to upper 70s with a few 80s thrown in here and there through out much of this time frame....Also most of this period shall be rather humid..This forecast cycle is way out in time so things could change...Will keep fine tuning this as we head through the period...

So to sum up this whole forecast cycle....

Looks like summer is going to be taken over...People will not have to worry about the year without a summer...Though I would have to admit it was sure looking that way for awhile....
