Forecast problems shall be found with rain chances today through Monday and then again Tuesday night through Saturday...Temps will also be tricky through the entire forecast period.
Current Conditions...
Temps this morning starting out on the warm side...Mainly in the 40s a few stations reporting temp at 50...Dewpoints are running from the middle 30s to the lower 40s....Radar is showing some light returns up in our far Northern FA of MN..Skies range from partly cloudy to mostly cloudy per satellite and SFC OBS...
For today through Monday.
SFC analysis shows a 1001 MB low pressure in Southern Canada with cold front reaching into the Eastern ND,and SD..Cold front is forecasted to move into and through the FA today,Winds will be switching from the South to a West/Northwest as the front pushes through...Did keep the chance of showers alive,though moisture is scant...Front will still be close enough to our WI Zones to keep the shot of showers here on Monday..Temps today will still be rather warm...50s seems the way to run....
Tuesday...
1028 MB high pressure build into the area.This should ensure the FA a nice day..Light winds..Temps will be a few degrees cooler that they were on Sunday...
Tuesday night through Saturday..
Models still not agreeing on the next system to move through the area,though slowly starting to come closer..Long range models GFS/ECMWF now agreeing that the upper level low should remain well to our South in KS,and MO areas....If this trend keeps pointing in that direction we may very well need to remove the rain from the forecast and run with mainly cloudy skies...As moisture will remain well South of the area...As of right now thinking is to leave rain in the forecast until short term models latch onto this system and we see how they handle it...Temps shall range from the upper 40s to lower 50s with lows in the 30s
