Good Sunday to one and all. December is off and running on a very mild note with temps in the 60s. Now some gusty showers join in on the fun and these showers will take us into early Monday. All of this is the start of a very active weather pattern that should start to turn wintry in about a week or so.
Showers will increase today from west to east and I can’t rule out a clap of thunder. These showers will be scattered and will carry us into early Monday.
A stout cold front will then sweep in here late Tuesday with widespread showers and gusty winds. You can see what I’m talking about on the GFS…
That front will drop some decent rains and also cause a nice drop in temps into Wednesday.
Our pattern is kicking it up a notch as things become very active and that’s a sure sign of a major pattern change. That’s exactly what we have coming by next weekend into the following week. I’m seeing many national folks now picking up on this change and some are even highlighting the same December 7th-14th time frame I’ve yapped about since Thanksgiving.
The jet stream will undergo a major adjustment and that will send a deep trough into much of the country next weekend. Several areas of low pressure are likely to be working underneath this trough and that means the devil will be in the details with each system. The models will handle these storms very poorly as there is a lot going on. They will continue to show the much colder pattern, but don’t settle on any one solution of any storm until within 2 or 3 days.
The first system should roll in on Friday and I think this is a rain maker with colder air coming in behind it. The storm that follows is the one I’m keeping my eye on because there is a growing signal this one could be a big system. It will be all about the track with that one, but the Canadian Model shows something similar to what I would expect from this far out…
The new European Model looks fairly similar to what the Canadian is showing.
The pattern for the second half of the month has the look of one that can produce some extreme wintry weather across the country. Only time will tell if we get in on the real nasty stuff.
I will have another update later today. Have a great Sunday and take care.
