More snow on the way...

Forecast headaches...Snow,and cold...Same old story
Current Conditions....
Temps took a hit again last night..At this hour temps are in the teens to twenties below zero.SFC OBS showing partly cloudy to clear skies through Northwestern WI,along with Eastern MN.

SFC Analysis...
This morning we find a ride of high pressure over the area.This has allowed skies to clear out over night and temps dived to the teens and twenties below....Our next storm system is over the ID at this hour..

Today....
Arctic air ridge of high pressure remains in control of the weather...The SFC high it's self should be around the Northeast OK area pressure readings around this high are coming in at 1038 MBS..Meanwhile up in our neck of the woods we see pressure readings around 1028 MBS...Winds today shouldn't be a big factor around 5 to 10 MPH,however with temps only forecasted to be in the lower to middle single digits wind-chills will still drop to around -20 to -30 at times today...

Tonight through Tuesday...
We see the storm system over ID move into WY,another low pressure gets going over Eastern CO...Trof will extend North of the WY low into SD,and ND by 00z Tuesday.By 06z Tuesday the we see a 998 MB low pressures over far Southern SD/far Northern NE...Trof reaching North from said low into the Central parts of the SD,and ND...Low over CO deepens to around 996 MBS...By Tuesday 12z low pressure over NE is forecasted to scoot Northeast into SD,said low should weaken to around 1001 MBS..Trof will reach from low into Southern MN, and WI....With Southerly winds out ahead of the low we should see some over running snows...So using different methods I can up with around an inch or two of snow for later tonight,using the same methods looks like 2 to 5 inches for Tuesday morning into the early afternoon...Total storm accumulations could range from 4 to 6 inches... Temps will remain cold through Wednesday....

Wednesday...
Will have to keep the snow chances going as models still have the low close enough to the area some models are trying to strengthen the low if this does indeed happen parts of my FA could see more snowfall,around another 1 or 2...This remains to be seen right now....

Wednesday night through Christmas day...
A 1016 MB high pressure will take control of our weather...This will allow temps to drop to below 0 for over night lows,However Christmas day is looking really nice with highs reaching into the upper teens...

Friday through Saturday...
Looks like another system could effect the area.The way it looks right now models are all over with this system so my confidence is really low with this forecast period...Temps do look to warm into the 20s on Friday only to drop back off once again ....
