Snow next week?? maybe..

Interesting weather pattern shaping up for next week..We been talking about this for sometime time…Looks like our first snowfall of the session may be on the way…. We will get to this in while….


***FORECAST ANALYSIS AND DISCUSSION***

This afternoon the FA is locked under clouds and light rain showers/sprinkles as a cold front is working its way through the area..Cold front is knocking on our front door…Winds will be picking up after the frontal passage, though the strongest winds will be found out over in MN….. Tonight cold front races off to the East/Southeast should see skies become partly cloudy…. Thursday we see a 1018 MB high pressure build into the area this will bring us clear skies, with rather strong CAA moving into the FA don’t except to see temps warm a lot… Upper 40s to lower 50s seem the way to run.. This cold air will be short lived as the high pressure slips down into Northeast MO return flow should begin tomorrow night, As winds become more out of the Southwest..Lows Thursday night in the middle 30s… Friday WAA well under way under sunny skies temps should reach for the lower 60s across much of the area… Somewhat cooler air returns for the upcoming weekend similar today as another cold front and a 1001 MB low pressure system moves towards the area…..Should also see a chance at some light rain showers/sprinkles once again…Rain chance will be on the increase as we head through the weekend into early next week….

***EXTENDED FORECAST TUESDAY NIGHT THROUGH HALLOWEEN***

This is where things could become interesting in the Tuesday night/Wednesdays time frame….GFS shows an 981 MB low pressure along the MT/Canada border… GFS pushes this low into far Northwestern WI/Western Lake Superior by Tuesday night and deepen low to around 970 MBS then it races the low Northeast well into Canada…. GFS shows a rather cold punch of cold air as a cold front plows through the area, thickness values drop off, 540 thickness line well to our South and East for late Tuesday night and Wednesday… It this does pan out this would lead to rain and snow showers becoming all snow showers….Now looking at the ECMWF model we see more problem come into play…This model does have a low pressure along the Canada/USA border it has the low somewhat weaker around 987 MBS..Also we see a 998 MB over the OK panhandle this low is forecasted to lift Northeast to around Southern IA/Northern MO by Thursday… Then through Northeast IL Thursday late afternoon then into Canada Friday…ECMWF does show warmer air in place over the GFS’S colder air in place…Though a Northwest flow is forecasted to become stronger… So as one can see many problems with this forecasted time frame… Nevertheless the potential does exist for our first snowfall of the session… We shall see….. Bright side Halloween looks to be dry,may be on the cool side, but no Halloween blizzards in the offering...
