Forecast + some info on yesterday's problem!

Forecast is for the most part cut and dry...Chances of snow creep back into the forecast for Saturday through Monday... Yesterday's problem is address in the long term forecast..So no long term forecast today.....

CURRENT CONDITIONS.....

Temps are starting this morning in the upper 20s to near 32...Winds are rather light for the most part from the West Southwest though some stations reporting wind gust from 10 to 20 MPH as of 6 AM..Skies range from partly cloudy to cloudy across the area this morning

SFC ANALYSIS......

This morning pesky low pressure is now just North of lake Superior...High pressure system building into the area from the ND/SD.

TODAY THROUGH SATURDAY.....

Weak area of high pressure is forecasted to build into the area....This will slowly allow for skies to become partly cloudy..Satellite showing areas of clear skies in parts of WI and MN...However do see some clouds trying to work Southward,and area of clouds trying to work Northwards out of IA..Looking at the 850-500 MBHUM charts we do see REL HUM dropping to around 30 to 40% through out Much of my WI zones so partly cloudy seems to way be the way to run ..Far NW WI REL HUM still up around the 60 to 70 % at 12z today so mostly cloudy skies are in the forecast for that area...Temps today will still be held at bay as West Northwest flow keeps diving South...So highs in the upper 30s North to around 40 South look to be passable.....Tonight partly to mostly cloudy skies shall rule much of the area as we see per 850-500 MBHUN charts REL HUM increase to 60 % in my Southern WI zones and still hang in the 65 % to 75 % in my Northern zones....Lows tonight will be colder than they were Wednesday night....Should see upper teens North to lower 20s Central maybe middle 20s far Southern areas...Friday through Saturday look for partly skies and high temps from the lower 40s North to middle 40s Central and South...Lows in the middle 20s...So below norm temps keep everyone wondering were spring is...

SATURDAY NIGHT THROUGH MONDAY NIGHT....

Here is when things get a little tricky,and a little interesting...ECMWF/GFS not seeing eye to eye on this next storm system just yet...Lets talk about old reliable...ECMWF...This model show a piece of energy digging into the OK/TX panhandle areas,then it spins up a 989 MB low pressure in said areas..This low is forecasted to eject into Central KS late Sat night/early Sun morning hours...said low then tracks to the East/slightly NE into Eastern IL/Western IN..Low deepens to around 997 MBS as it makes it's trip across said areas...Meanwhile we see a 1038/1039 MB high pressure building Southward out of Canada into the Eastern Rockies...Hence the further Southern track of this system..That's if it plays out that way...Ok lets break down the GFS and see what he's saying about this....Sat 12 UTC GFS has a 1000 MB low over SW KS/OK/TX panhandle....By 18 UTC low is forecasted to be in South Central KS..By 00 UTC Sun..Said low is forecasted to be around Eastern KS from there the lows track through Northern MO into Central IN by 18 UTC SUN...GFS still keep this low at the 1000 MB level until Sun night when GFS deepens low to around 996 MBs...So track is close to the ECMWF,however the strength is weaker...I have been seeing a trend to the South with models over the last two days..So with that thinking....Far Southern zones will have the best chance at seeing precip from this system,however models keep trending in South..My Southern zones may every well end up high and dry.....However at the same time we do see a shortwave dropping South as of right not I'm not to trilled about moisture return as the System down South should keep moisture tied up there...This shortwave really has not much of it's own to work with...Still for now will have to keep precip going,however that may be pulled in later forecasts or updates....Small chance of snow moves in for Sat night and holds through Monday.....
Sat night lows should reach the middle 20s once again...Highs on Sunday will be cooler with middle 30s across much of the FA,a few upper 30s may pop up in my Southern zones....Sun night lows fall back into the middle 20s,high still cold for Mon ...Middle 30s North to upper 30s South.....Lows Mon night fall into the lower 20s South and Central to as cold as the upper teens North....

TUESDAY THROUGH WEDNESDAY....

High pressure builds back into the are so will run with Mostly sunny skies through this time frame...Temps on Tue should be in the lower 40s....Lows Tue night drop back into the middle 20s South and Central while lower 20s seem like a great bet North...Wednesday highs scoot up to the upper 40s Central with a chance at a few 50s in my Southern FA..North parts of the FA lower to middle 40 should work out ok.....

LONGER TERM.....
