Changes Brewing...

Sunday will start of with areas of frost, especially north of I-80, and then southerly winds take over ahead of our next front that will move through Sunday evening allowing temperatures to reach the low to mid 60s!  As the front passes, we can't rule out a few showers north of the area.  After that temperatures cool down significantly and all eyes are on a clipper system set to roll in on Tuesday that could bring everyone's (least) favorite four letter 'S' word...no accumulation is expected at this time, but the flakes may be flying!

 The first image is of the GFS model (an American model) showing the area of precip passing directly over us, and is the most aggressive with the snow probability.  The 540 decameter line (the thickness between the surface and about 3 miles above the surface) indicates the transition between the rain and snow.  Since it's still Fall, we generally look for lower thickness levels for snow.  (This is valid ~1PM Tuesday)

 This is the European model which generally does pretty well in handling wintry precipitation.  It's got a very similar output to the GFS, but is just a bit less progressive.  The GFS is also much faster (this is valid ~7PM Tuesday).

This is the Canadian model, another model meteorologists use to forecast.  Generally this model is colder and more aggressive with systems coming from Canada, and it's evident here that this model is colder.  Nonetheless, it puts precip over our area.









The true outlier is the North American Model (NAM).  It is much less aggressive with the precip chances, whether it is in the form of rain or snow.  One thing is for sure, temperatures are going to be very chilly for October standards!
