Arctic air is set to pour into the area starting this afternoon...This will come in two shots..First one starting today,the second shot coming in Wednesday...Highs after today will not make it above zero ! Lows will range from -20 to -20 with some areas getting down to -40...Details below....Will have to deal with a shot of snow this morning...Then again Tuesday night into Wednesday morning.....
CURRENT CONDITIONS...
Temps ranging from 10 above at New Richmond to -6 at Hayward..Here at the Rice Lake office we are now at 3 above after an over night low of -9...Skies are mostly cloudy...Radar is showing returns however SFC OBS from stations and weather observers showing no snow reaching the ground just yet...Highest DBZ in my FA is around 13...With that most of the returns are just virga...
SFC ANALYSES.....
This morning's weather map we find a 1012 MB Low pressure over Western IA...We see a strong 1044 MB high pressure over Southern Alberta Canada....Finally we find out next trouble maker sitting over the Golf of a Alaska...
TODAY THROUGH WEDNESDAY....
Low pressure over IA is forecasted to move into Southeastern IA by 00Z Tuesday,By 06Z Tuesday the low shall pushed into Southern MI....Meanwhile high pressure will be building into the area from Canada..Pressure gradients will increase between this two features..Looking at the 3 hour pressure tendency off the RUC....We see starting this afternoon pressure tends will start to raise from .5 MB/HR to 2. MB/HR..The highest pressure raise will be in Southwest/Southern MN This lines up rather well to were the NWS has Winter storm warnings and Blizzard warnings ...This would also lead one to believe winds should be in the sustained range of 20 to 30 MPH with wind gusts up to 40 MPH..This afternoon into this evening.....Up in our neck of the woods,this would mean winds of 10 to 15 MPH later this afternoon and picking up to 15 to 20 MPH tonight with some gusts up to 30 MPH...Wind-chills today won't get to out of hand until later...Most of the day we should see wind-chill values from -10 to around -1 or so....Tonight....light snow should have ended,if not it will.Thinking is most of the FA shall see 1 to 3 inches by time all is said and done...My Northern WI areas may not see no more than a trace..Though some LES is going to possible, the window won't be open to long to get and keep a good fetch of warm air off the lake...Skies will become clear,wind shall remain rather nasty,however should begin to decrease after the clearing line moves through.....Temps for today some what tricky..As some of my FA starting off below zero while the Southern areas starting off in the middle single digits....So I'm going to run with a range of temps 8 to 15 should cover that rather nice...This afternoon temps could start to fall as winds pick up from the North/Northwest...Over night lows -20s North to - teens Central and -12 to -9 South....Tuesday high pressure will control our weather..Under sunny skies and light winds...Temps will not get above zero most areas...Southern FA shall...Central and Northern parts won't....Our next system dropping South out of Canada will kick in some WAA very weak though...This will also bring a chance of some more light snow to the area...However this system is forecasted to take a track more South then the current one,which track more South than what was forecasted early yesterday morning...So as of right now I'm really to thrilled about this system....Lows Tuesday night should be in the same range as Monday night lows...Highs for Wednesday -5 below Central and Northern areas to around either side of zero in the Southern areas...
WEDNESDAY NIGHT THROUGH FRIDAY...
The coldest air thus far this winter will settle into the area Strong High pressure is forecasted to build into the area..Pressure readings on this high are remarkably high...1050 to 1052 MBS....Lows through this period shall range from the teens below zero in my Southern areas...Central and Northern areas twenties to thirties below zero...Some spots could dip to below -40 at a time...
Temps will remain well below zero for highs in the Central and Northern areas..Single digits below in the Southern areas....
Friday computer models do show some WAA moving into the area...I'm not 100% thrilled about that so will keep temps below zero Central and Northern areas..As these areas will have almost a 20 to 30 degree raise to get to zero.....Could happen but I'm not seeing it just yet...Also Friday night lows in the Central and Northern areas are forecasted to dip to the upper teens below zero to maybe -20...Southern areas could see temps closing in on high barley above zero Friday with low not dropping much.....
SATURDAY THROUGH SUNDAY...
The cold snap is forecasted to break...So warmer air on it's way....Temps on Saturday I'm going to hold them down below model guidance...Will keep them in the upper single digits to around 10 in the Central and Northern areas and around the middle teens Southern areas for highs...Low will run with either side of zero Saturday night....Sunday highs may be in the middle to upper teens Central and Northern areas...To around twenties in the Southern areas....
LONGER TERM...JAN 17 THROUGH JAN 25....
Long range models are hinting at temps going above norms for this time frame...Also precipitation look to below norms....Will we make it to our aver snowfall amounts for the year ?.....We shall see.....
