Not So Scary Weather

As of 11:30 AM this halloween, it's already 68ºF at the Salt Lake City Airport.  The record high for the date is 76ºF and it's looking like we will make a serious run at that.

Other than the fact that it may be windy later today, you can't ask for better Halloween weather.  That's great news for trick-or-treaters who won't have to cover up their costumes with bulky layers to keep warm.

Tomorrow looks to be an exciting weather day with the potential for some thunderstorms, strong winds, and a vigorous frontal passage.  After that, much depends on the details of the postfrontal flows and the whims of the lake.  I still see a lot of spread in the model forecasts, although most are leaning towards periods of snow beginning tomorrow afternoon through Monday.  My most likely accumulation for the central Wasatch is 4 to 8 inches, less if the NAM wins (drier post frontal environment),  more of the GFS wins (wtter post frontal environment) and we also get the lake going.
