Record WPAC warm pool in conjunction with the cold over Siberia continue to create the very strong thermal gradient leading to the faster Pacific Jet and dominant Northern Stream Storm track. The tropical warm pool near the equator and the record subtropical warm pool to the east of Japan and south of the Aleutians both enhance the Southeast ridge. Plus the record Gulf Stream SSTs also contribute. Models tend to underestimate this long range influence as we are seeing with the new forecasts in early December with stronger Southeast ridge than originally forecast. Once this pattern becomes established, it can linger longer than expected as we have often seen heading into December over the last decade.

Who’s going to start the thread: “Post Turkey Day Hooker” :BEYOND THANKSGIVING, SIGNS CONTINUE TO POINT TO A TURN TOWARDS A MUCH MORE ACTIVE WEATHER PATTERN ACROSS THE CENTRAL CONUS THIS WEEKEND GOING INTO THE FIRST WEEK OF DECEMBER. OVERALL, THE LARGER SCALE PATTERN ACROSS NORTH AMERICA CONTINUES TO FAVOR UPPER TROUGHING SETTING UP ACROSS THE WESTERN CONUS AND UPPER RIDGING ACROSS THE SOUTHEASTERN CONUS DURING THIS PERIOD. THE PRESENCE OF GREATLY ENHANCED SOUTHWESTERLY MID AND UPPER LEVEL FLOW INTO THE LOWER GREAT LAKES IN SUCH A PATTERN IS NOTORIOUS FOR STEERING NUMEROUS IMPULSES ACROSS OUR REGION. ACCORDINGLY, SOME PERIODS OF ACTIVE WEATHER, WITH RAIN AND/OR SNOW IS POSSIBLE AS WE HEAD INTO NEXT WEEKEND. IT IS IMPORTANT TO NOTE, HOWEVER, THAT AS IS TYPICAL, WHILE THE PATTERN LOOKS INCREASINGLY ACTIVE, THE FINER SCALE DETAILS THIS FAR OUT REMAIN LARGELY UNCLEAR AND WILL NEED TO BE IRONED OUT IN THE COMING DAYS. NEVERTHELESS, THIS PERIOD WILL BE MONITORED CLOSELY FOR POTENTIALLY IMPACTFUL WEATHER SYSTEMS ACROSS THE CENTRAL CONUS THAT COULD IMPACT HOLIDAY TRAVEL. STAY TUNED. - LOT

The 1st week of December does look mild though. Delayed but not denied ?
-
I think an amped storm brings us rain during this period. But a 2-4 incher could be in the cards if the timing is right especially for NW zones.

The models are really struggling. Thanksgiving and its weekend warmup went poof so is the week 1 warmup which consists of plus 20 day skewing the entire week Here's another warm bust in the making

About as boring as you can run a -2. If we ran a +2 like this people would be saying it was faux warmth. But yeah, it’s been fairly seasonal with no real ups and downs. -
Cant believe how warm it was the last week. 83 yesterday, and muggy. Felt like the begining of September. As usual, we are still lacking in the rain dept. Half inch for the month. Today should be a beautiful with less humidity and a high temp of 75. I have to admit, I am enjoying outdoor activities with this warmth.

Seems like guidance is really struggling with the Pacific pattern in early December. There will be some very cold air somewhere in North America. Not much more is certain yet.

Latest 17F or colder at CON is 12/12/1998. That’s pretty far out there still. -

Consistently cold mornings her for weeks though. -
I see +NAO/-PNA

Yes. You went against the grain and said weeks ago that you thought the November stratospheric warming was going to be a weaker wave reflection event and the SPV was going to rebound and strengthen quickly again mid-late December. If that works out, then it will have been a very impressive call

39 here. One last leaf cleanup today and then setting a neighbors oak tree on fire. It’s still half full and I’ll be damned if I let it blow leaves over to my yard
