Well as usual dates can shift around and I was hoping the Saturday deal could have worked out. The models had an interesting configuration at 500mb about a week ago...but now the Saturday deal looks rather meager. That Thursday through Sunday timeframe was the time I was hoping for something interesting. The good news is that next week and beyond definitely hold some interest as we become active no doubt. The amount of storms and QPF seem the least of the questions.

Good point

 

Will's earlier set of dates/possibilities shows this idea well

Will the low SSTs give coastal regions a bit more wiggle room when it comes to the theoretical R/S threats? Not that it would help in a big ole cutter, but just curious about the impact in marginal/on the line situations would be.

 

Well 38-39F SSTs certainly are better than SSTs in the mid and even U 40s to start out December. They'll cool off if the pattern allows it to, right until mid March or so before levelling off and getting some small diurnal variations.

Anyone can weenie me on this, but I'm bored, so was looking around the always accurate DGEX has back-to-back SWFE ala '07-'08 coming up...

 

Extrapolating the NAM (always a good idea) comes out with a nice event this weekend from the Pike northward...40/70, Will, Hunchie, all in a good heavy burst of overrunning.

Just get the qpf up here, We will make it work, That has been what we have lacked, I will roll the dice with marginal cold, If we have to get a couple mixed bag events so be it

To further confuse people... here's a 180 hour prog of the DGEX for the next week event... you want SWFE QPF, here it is, haha.  Another classic SWFE climo from Pike northward.  The validity of this or any solution is right up there in accuracy along with a 5-year-old with crayons at this point... but I love the almost textbook SWFE solution. 

 

-10C H85 temps near Dendrite with 0C near ORH.  Should just change the year of this to January 2008.

 

All joking aside, you can see why ORH/Will has been hammering the better CAD with the second system.  You can see that here with a pretty cold surface until the dryslot would race in.  Pure boredrum on my part to be posting this, but sort of goes along with what some of the METs have been speculating.

I think that it should help in keeping any front-end snows from changing quickly with a ne wind  After reviewing some earlier posts seems like people are throwing around 07-08 as the type of upcoming pattern.  I don't remember that year as having any real extensive cold like this year.  So while pattern may be similar, would there be more cold to work with, esp. with front-end snows?

You would not like that analog being in Fall River. That year had an epic gradient from you to southern NH.

I think you got maybe 35" or so while southern NH got 100". Anyways, I think that was a example as the types of storm track possible. Personally, I don't see a 2007-2008 pattern as the PV is in a more favorable location for us. Also, the systems may have some Gulf origins unlike that year when they were more Plains systems ejecting northeast and just tapping into some Gulf moisutre.

 Oh yeah that year was horrid.  Storm after storm sailing to our north.  What you have to expect a lot of years living in extreme sne.

Don't have the time these days ... but just a cursory eval of the main players and teles ... seems evident that a period of more storminess overall is in store, as a "somewhat" less meridional flow allows for actual moisture transport into the mean, well-established polar/arctic air.  Last few cycles of the GFS have several moderate winter storm threats as I'm sure has been heavily covered.
