Forecast

Some light snow along with some freezing drizzle possible today through tonight...Warmer temps on tap for much of the upcoming working week,along with dry weather...Then back into the cold we shall dive...Not thinking the upcoming cold snap will be as cold as the one we are climbing out of....

CURRENT CONDITIONS.....

Temps this morning are a lot warmer than yesterday morning...Temps are mainly in the single digits above zero...We do see some 10°s showing up in our Western/Southwestern part of our MN FA......Radar is showing some light snow/flurries through out the area....Though it's not picking up on all of the light snow/flurries..SFC OBS at this hour showing light snow/flurries...no mixed precip as of yet..One can easily see where the cold front now sits with the SFC OBS...Won't go into details on that...

SFC ANALYSIS....
.
This early morning we find a 1006 MB low pressure over far Northwestern MN..Large are of high pressure over the Eastern and Southeastern states....Meanwhile large ridge building out in the Western States...

TODAY THROUGH SUNDAY NIGHT....

South winds between the high to our East/Southeast and low pressure to our Northwest has brought in warmer air to the FA...Low pressure is forecasted to move from Northwestern MN right through Central WI by 18Z today..This will keep the chance of light snow going through out the FA....Would think 1 to 2 inches will be possible up in the Northeastern areas of MN while around far Northern WI area could see 1 to 3 inches of snow...Looking at the cross section charts from INL MN to HYR WI...We could also see some off and on freezing drizzle mixed in from time to time...As we see a warm layer air between the 925 MB to 700 MB layer...Temps in said areas range from -12c to -10c....Colder air higher up in the 600 to 600 MB layer ranging from -14c to -24c..I did not add that wording to the forecast as I feel it wont be that much of a problem,however we will have to watch it...Meanwhile as the low moves through the area winds will be switching to the North/Northwest through out today......By 00Z low pressure will have moved to Western MI...Still will keep a small chance of snow going through tonight and Sunday through much of the FA...As we find a weak trof moving into and through the area...Temps today should be in the teens,lows tonight single digits to around 10 should do it...

MONDAY THROUGH THURSDAY.....

Large ridge of high pressure will take control of our weather...Should be a dry work week coming up...Temps will be rather nice,with highs ranging from the middle to upper 20s across our Central MN,and all of my WI FA...Will upper 20s to lower 30s across our far Southern areas of MN....Lows should mainly be in the upper single digits to the middle teens...However we will start to see a slow cool down as we end the work week.

LONG TERM FORECAST....(JAN 23 THROUGH FEB 2)

We will see temps drop to -12 to -8 C through out the whole FA...By 00z Saturday temps shall drop to -24C in our Far Northwestern areas of our MN FA..While the rest of MN and WI FA area temps will range from -16C to around -20C..By 06Z temps shall be around -24 C through out the whole FA..By 12Z Saturday look out as temps fall to around -28C to -24C..Looks like the Arctic air will hold strong through much of the this week With a slow warming trend towards the end of the week...By Monday Feb 2 we find temps warming to a range from -8 to -4.....As far as precip goes...We start the period on a dry side.This trend does seem to hold through this time frame...We may see some snow move into the area around the middle of this time frame...Won't worry about that right now...But get ready for another cold period as more Arctic air is set to move back into the area....
