***Major Winter storm***(my AFD)

This AFD will focus on the major winter storm the is forecasted for the FA....

CURRENT CONDITIONS....

Temps this morning starting of cold once again single digits up North and middle teens to lower 20s Central and Southern area...Most areas reporting clear skies over in WI partly cloudy to mostly cloudy skies rule


SFC ANALYSIS......

This morning's weather map show area of high pressure over the FA...We see out trouble maker now digging into the MT/ID area...Well get right to that..

TODAY THROUGH MONDAY.....

High pressure will remain in control of our weather For the most part will keep things dry for most of the forecast area,However on Monday did bring in light snows through our Southern and Central zones of MN and most of my WI zones....

MONDAY NIGHT THROUGH TUESDAY NIGHT....

The NWS does have a winter storm watch out for most of the FA...Only the far Southern zones of WI are clear form this watch attm,however my thinking is the NWS will issue a winter storm watch for those areas by late afternoon..
ECMWF and GFS for the part are seeing eye to eye on this winter storm to pound the FA...987 MN low is forecast to be in NE CO Late tonight early tomorrow morning...Said low is than forecasted to lift Northeast towards into SW IA on Monday..From there the low is than excepted to move into SW WI than Northeast through our Eastern zones....This track will lay down a very good area of heavy snow for most of the FA...It does appear right now my MN zones will see the from 6 to 12 inches with locally higher amounts...My WI zones should see a range of 4 to 10 inches of snow..Here the highest snow amounts as of right now would occur the farther North you go...This system will also bring strong winds with it....Winds could reach up to 26 to 28 MPH might even be high,will depends on where the low ends up going,either way this will cause blowing and drifting snow,along with near blizzard conditions from time to time....

WEDNESDAY THROUGH FRIDAY.....

System moves out of the area,weak high pressure build in,however will keep off and on light snow/flurries alive as CAA wrings out what little moisture is left....Another storm system for the weekend or early next week..No time to deal with that one right now,but it could be a big one also....Models still all over the place with it......
