Pattern/storm inverted trough thread early Jan


Damage In Tolland

Recommended Posts

It's funny the differences between the 12z and 18z NAM at 500mb are huge. 12z had the ULL diving underneath us (blizzard, probably) while the 18z has an enlongated ULL and winds up producing a nice inverted trough.

It's going to take some time to figure out exactly what will happen. 18z NAM was nice... but 12z was sweet.

No doubt the 12z NAM was going to be a good one.

yep...same thinking...the NAM took a jump towards the GFS with it's PV placement.

Ultimately it slowed the s/w just off Cape Cod at 60h on the 18z NAM by several hours while maintaining speed on the other systems. I'd like to see that continue.

Still a lot of time and so much changes each six hours.

Yeah the lead impulse from the southern stream outruns everything while staying rather weaker than what the 12z run had. Also the NAM now has the SPV over LK Erie or eastern MI instead of over OH. 12z NAM would have ended as a bomb IMHO, but 18z run was good as well. Still a lot of run to run inconsistencies. 00z Thursday should give us a better clue as to what is happening with this potential winter storm/inverted trough.

...TROUGH THROUGH THE GREAT LAKES AND NORTHEAST D2/D3...

THE NAM AND CMC ARE ON THE SLOWER AND DEEPER SIDE OF THE MODEL

SOLS WITH THE DEEP TROUGH AND ASSOCD SFC FEATURE OVER THE ST

LAWRENCE VALLEY ON D3. THE MORE PROGRESSIVE AND FLATTER GFS/UKMET

AND ECMWF SOLNS ARE FAVORED GIVEN THEIR GOOD RUN TO RUN

CONTINUITY.

well ... that's certainly good ole news :axe:

It looks to be the American Models vs the Foreign Models debate once again with this setup, quite frustrating at this moment. I think you can bet on a stronger and faster northern stream disturbance than currently modeled. I hope the models trend towards a stronger SPV passage than what the CMC and EURO are showing as well as the UKMET.
