My AFD

Did we go back in time ? Sure does seem that way,as we are talking about another major snowstorm...This discussion will focus on the winter storm to pound the FA...Very little in the way of long term discussion...
Current Conditions...
Temps are rather warm this morning,single digits to around the upper teens...Radar is showing a large areas of light snow through out the FA DBZ running around 10 to 20 or so right now..Snow is moving Northeast...Sorry not much more time left for the SFC OBS....
SFC analysis....
Models showing a trof over the Eastern Dakotas back down into Eastern NE..Mean while we see a low pressure over OK this low is forecasted to move almost do East to NC This low will not have a impact on our FA...We find a low pressure over Canada this is forecasted to dive in MN by 18z today then into Southeastern WI by 06z Sunday..The low is forecasted to move up towards Door County WI by 12 Sunday...Meanwhile as the low is pulling away we see another trof pushing South from said low.All these features combined will bring the FA an extended period of snow through the weekend..
Today through Tonight....
Snow will become widespread this morning and become heavier as we head through the day and into tonight as the low and first trof pushes into the area...
Sunday and Sunday night....
We still find the low over in WI around the Door County area with a trof being drove South into the area from said low...This will help keep snow chances alive....For the most part most of the FA will see less than inch maybe and inch of snow,However over the Northeast tip of MN they could pick up another 1 to 3 inches of snow...Wind will also increase in speed across the FA...This will lead to blowing and drifting snow...Blizzard conditions will also be possible through out the area....The Arctic gates open back up allowing for more cold air to pour into the FA....Temps should start to fall off in the afternoon...Wind-chills will also become a problem for Sunday into Sunday night..By Sunday night the light snow should becoming to an end across much of the area...Will keep it alive in the LES belts of WI and the Northeastern tip of MN....
Monday through Monday night....
LES will still be possible in our WI snow belts,otherwise look for a break in to snow today as we bask under mostly sunny skies...Temps will be a cold though...
Tuesday and Tuesday night....
Here we go again another winter storm on tap...This on looks to be a quick hitter through...Low pressure over CO is forecasted to move to move into Northeast IA/ Northwest IL/ Southern WI Tuesday..This track as of right snow should keep the heavy snows in our Central and Southern zones of MN and WI....We will fine tune this in Sunday's forecast...To much work going on with this weekend's winter storm...
HWD will be issued shortly...
Watches/Warnings....The NWS has issued a Winter Storm warning for the entire forecast area.of MN,and WI...
