If you're wondering when our next cold snap and/or chance of snow is, well, then follow along with the following six images below.  First off, the first graphic there quickly shows you we've got no cold weather or snow chances over the next seven days.  Ironically, we're warming up for our first December weekend.  So, let's go beyond the 7-day outlook with graphic number two.

Graphic 2: The second image is the GFS model surface temperatures for Wednesday, December 5th.  Clearly you can see the cold air spilling in from Canada.  Our high temperatures could drop to the upper 30s and low 40s. 

Graphic 3:  The third image is the EURO model showing a similar cold snap next Wednesday. 

Graphic 4: The fourth image shows the jet stream taking a dive, which gives us more confidence in the cold snap next week.

Graphic 5: What about snow chances with this cold air?  Probably not.  Like we've seen several other times, the cold air doesn't catch up in time.  The moisture from the storm system will be moving out too quickly Tuesday night, before the cold air could turn it over to snow.  That blue line is the magic "540 snow line", and it doesn't look like it will drop far enough south to change over to snow.  So, basically, it's going to get cold next week, but snow chances remain low.

Graphic 6: The next cold snap looks like it could arrive two weekends from now.  This would be December 8-9th.  This storms system looks larger, with perhaps enough cold air on the backside to produce some snow chances.  However, this is long ways out, and the confidence is very low for this storm system. 

But, it does appear our weather will become more active with some cold snaps as we head further into December.  If you don't like the cold weather, enjoy this first warm weekend of December coming up!
