Pattern October Thread

All but the 0z gfs keeps the LR rather transient. Seeing a lot of 50/50 low-type activity, which should promote some occasional wedging. But the big stable west cost ridging pattern seems to take a break for a while.

The 0z gfs would give me confidence that we would be more below normal than above, once the pattern changes. The rest of the guidance seems variable, but at least the big heat and high dew points look to be gone....if it holds.
 
The front has all the makings of one of those pencil thin lines with some trailing showers as the 85-7 trough lags behind the sfc front/pft. Probably only a .05-.2 type event. If we get the deeper trough next week we get a more significant rain event
Y’all might get the moisture from Pamela at the end of the week??
 
Euro trying to find a way to find a warmer period, noticed this on the 12Z EPS yesterday but didn’t think much of it, per this look it would be transient tho D2B92898-1ECB-471D-99A7-596E04312AE4.png92F45A89-3B93-4E0B-9EDD-0F6B1179CADB.png9B4AAAE4-87EA-4E31-A5E6-7DB77CC6C85F.png

I do like the big high on the euro spreading into the plains. Don't like the big ridge Amp from the rockies into Canada and the fractured trough... that's a recipe for a cutoff and warm/muggy if we didn't wedge or get a clean trough
 

Gotta love the 600+ hour European … unfortunately can’t be trusted but I’ll take it for now as it’s showing what I’ve been thinking could happen for a while with an early start to winter with the help of that early strat warming taking into effect much earlier than we usually get … haven’t had a thanksgiving flurry in a while ??
 
Need to be really careful on how we evolve the SPV. If you bother it but let it come back, typically it comes back stronger and harder to disrupt, there’s cases where failed attempts at SSWEs have lead to a very strong stratospheric polar vortex later on which ends up leading to a off the wall +AO

The one time I got to experience a snowfall before Thanksgiving was in November 2000… I had 4 inches in Concord where I was living at the time, and then never got more than flurries the rest of the winter

That was a great event full on mashed potatoes falling. Could have been an awesome 2 week period if the coastal low didn't miss east in early December

Some type of SSW event is our only chance to see a possible cold start to winter. A weaker pv for sure. Dont want it too early either because, imo, it's tough to see a sustainable cold pattern to produce snow and ice in the south and se other than your typical favored higher elevations

It would literally be an antisocial winter. Just like 2018-19. :(
