Forecast discussion will revolve around the Arctic blast that is posed to move in and make camp over the area for the upcoming work week....Will talk about snow for Monday...
No time for current conditions this morning....
SFC ANALYSES...
This mornings charts we find a 1018 MB low pressure over Central MN..We see our next trouble maker over the British Columbia Canada....This feature will be the main interests as this will sever to give the FA a shot of snow,however the most important thing this system is going to do,it will open the Arctic gates and draw very cold air into the FA....Lets get right to it....
TODAY THROUGH TONIGHT....
Low pressure currently over Central MN is forecasted to dive into Southeastern IA by 18z today...This will produce some off and on snows through out the morning hours...Thinking is snow should end by middle to late afternoon...Little in the way accumulations forecasted...Will bring snow back to life for tonight as the next clipper system starts to move towards the area..
Monday...
06Z Monday we see the low pressure dropping into Central parts of ND..By 12Z Monday the low should be around Southwest MN...By 00z Tuesday the low should be around Southeastern WI.This has some good lift and a little more moisture to work with Will peg snowfall amounts from 1 to 2 inches in our Northern areas of MN,and WI...Our Central and Southern zones of MN,and WI should pick up 2 to 4 inches..Strong 1043 MB Arctic high pressure towards the Northwest,and with the low pressure to our South than Southeast pressure granites will really increase...Winds could gust up to 25 to 30 MPH through out much of the FA later Monday.This will lead to blowing and drifting snows..Temps should slowly fall from their morning highs in the teens....
MONDAY NIGHT THROUGH TUESDAY....
Arctic high pressure will control the weather through this time frame...Skies will clear out this will allow the first shot of Arctic air to dive South on strong Northwest/North winds...Once again winds could gust up to 25 to 30 MPH across the FA,,With temps falling from -20 to -17 wind-chills will become the main topic of interest...Wind-chill values could fall to near -60 in our Northern areas of MN..-50 to - 40 will be common through out the rest of the FA....
TUESDAY....
Models showing another,but weaker clipper moving South...This one appears it will track more to the Southwest...So not to thrill about snowfall attm...Plus with the colder and drier air in place it will be hard to produce any good snowfall amounts...However this system will ensure even colder air to drain into the area...
TUESDAY NIGHT THROUGH THURSDAY NIGHT....
Very large and very strong Arctic high pressure will build into the area..This high pressure is forecasted of 1050 MBS or so by most computer models...This is when the coldest air of the season will settle into the FA....
Temps through the middle and long term period (Monday through Thursday) will not climb above zero...Over night lows -20s to -30s along with a few areas getting into the -40s....
Some warmer air may be on tap for the upcoming weekend...We shall see....
