Signs of Winter?

Thursday, September 18, 2014 at 7:25 am


Scattered showers and thunderstorms likely late today (Thursday), tonight, and tomorrow.  A break on Saturday before another push of moisture brings showers and storms late Sunday into Monday.  Attention then turns to a colder storm for late next week.


The moisture from Odile all but missed Utah this time around, but the atmosphere is slightly more damp than it would typically be this time of year.  Add in dynamics from a low pressure system moving through northern Utah and you get showers and storms that are likely to form late on Thursday into Friday.

We will dry out by Friday night and have a break on Saturday and for the first part of Sunday before moisture pushes back into the area late on Sunday.  Another round of scattered showers and storms looks likely to last through Monday before we dry out again on Tuesday.

Now for the exciting part… Both the EC and GFS now have a trough dropping down off the PacNW coast middle of next week.  The trough is progged to progress inland next Thursday and Friday.  Both models currently show the trough weakening as it does so.  Still, this would be a much colder storm than we’ve been seeing lately.  Snow would likely return to the highest elevations.  We’ll have to keep an eye on it but it looks like around Friday of next week we could be much cooler and thinking about winter again.  GFS then follows this trough up with a second one for the end of the month.

This change in pattern is fairly typical during Fall, which is why I said just the other day that even if models show dry patterns continuing, they may just be slow this time of year to catch on to things.  Looks like they are catching on now…
