Forecast..SUCKS!!!!

Forecast headaches...There are many....Temps will be the main player through out the whole forecast cycle....As they will remain well below norms overall..I had to go back a trim temps down across the broad...Frost/freeze will also become a problem once again through out this forecast period...Today the problems will be showers and thunderstorms...Storms in my Central and Southern areas of MN,and WI..While rain in the Northern areas....Some storms still have the possibility of becoming strong to severe...Overall the severe weather threat has took a turn for the downside...More on that in a mintue....

CURRENT CONDITIONS....

Temps this morning are in the lower 40s where there has been rain/clouds...Middle 50s elsewhere's...Dewpoint still rather low lower to middle 30s...Radar showing a rather large area of showers,maybe a few t-storms Moving across much of my Northern MN areas...Also a few rain showers up over Iron County....

SFC ANALYSIS....

This morning we find a 1017 MB high pressure over LK Superior...Also find a trof located over Northern MN...Meantime we see a 1000 MB low pressure system spinning it's wheels over ND..Warm front extends South of the low into SD,and NE...Also a strong cold front now entering far NW ND...This front reaches back into and through MT.....

TODAY THROUGH TONIGHT....

First off showers have been moving through most of my Northern MN into my Northeastern zones of WI areas along the trof..Rain has been moving East ....This may lead to problems with the chances of strong to severe thunderstorms across my Central and Southern zones of MN,and WI,as the cloud deck from this trof is pushing East/South East....Also clouds have really started to pop along the warm front..Moisture/higher dewpoints have not made it into my FA yet...Dewpoints still in the 30s....Overall I think the severe weather threat is going to very low through out my FA...However if deeper moisture can make it into my Central and Southern zones,and the FCSTED cloud deck clears out before primetime heating there may be a few strong to severe thunderstorms...As of right now to many things going against it....Still we will have to see how this mess plays out this morning into the early afternoon hrs.....

UPCOMING WORK WEEK....

Temps take a dive right back to below norms again...No big warm ups in sight....Have ran with chances of showers and thunderstorms...With little daytime heating it won't take much to produce some showers/storms.With very cold air sitting aloft...
Northwest flows refuses to give up like most of this spring...Trend in the models is to keep it going right through the extended forecast period...So I did some major downsizing in the temp dept....There will be chances of frost/freeze conditions off and on right through this period....Same old song,and same old dance....Good news is if you like summer temps...Long range models are showing a nice warm up starting around the 324 hr forecast which would be Sat June 13th...If this all plays out we could see temps into the 80s..We can only hope!
