12/1/10 convective threat

Joe D not big on winds at all..though he tends to always play things conservatively

Nothing wrong with going conservative about the winds, especially this time of year. Really going to depend on how well we can warm sector and how high the sfc temps can get too. If we can end up in the lower 60's than that would certainly be enough to limit the inversion some and allow potential for some stronger winds to mix down. The CAA winds could end up being more impressive.

From OKX

WILL LEAVE OUT MENTIONOF THUNDER FOR NOW...BUT WITH FORCING FROM THE SECONDARY LOW PASSINGNEARBY...ASSOCIATED COLD FRONT...AND FROM THE LLJ...A FEWTHUNDERSTORMS ARE NOT OUT OF THE QUESTION. WILL NEED TO CONTINUE TOMONITOR THIS THREAT OF HIGH WINDS ON WEDNESDAY...CONVECTIVE ANDSYNOPTIC. RAINFALL THEN TAPERS OFF WEDNESDAY NIGHT.

It would ne nice if the LLJ came through during the daytime. Well, it may do that for CT, but it looks like it comes through ern mass at night. This really is a LLJ, because max winds seem very near 950mb..at least on the soundings I saw. Some of those winds were between 65-70kts on the gfs...even at 950mb. However, there does look to be a pretty good inversion.

There will likely be a pretty good inversion in place which alone is really going to prevent some of those stronger winds from mixing down, unless we happen to somehow warm into the upper 60's to near 70F and that doesn't appear quite likely.

One thing that may have to actually be hit a little harder is the potential for some flash flooding...while this system looks rather progressive the potential exists for some extremely heavy rainfall and rainfall rates. Potential exists for as much as 1'' to perhaps 3'' of rainfall in a fairly short amount of time. Not sure how drain situations are across the region and when leaf collection commences for certain areas but I imagine there are locations where some drains are clogged from leaves and such. That could locally enhance any flash flooding threat as well.

This isn't looking like it will be a huge flood threat but there certainly could be some minor issues in spots.

Looks like the better potential for stronger WAA winds will be down across NJ, looks like this is where the warmest low-level temperatures will occur and warmest sfc temperatures. Could see temps down there get into the lower to perhaps mid 60's with dewpoints just about the same.

As WE thought..conservative not the way to go here

OVERALL THERE IS MODERATE TO HIGH CONFIDENCE OF WIND ADVISORY

POTENTIAL...WITH SOMEWHAT LOWER CONFIDENCE HIGH WIND WARNING

CRITERIA ACROSS MOST OF THE COASTAL PLAIN AS WELL AS CT/RI/EASTERN

MA AS WINDS WITHIN THE BOUNDARY LAYER INCREASE TO 50 TO 65 KT.

Who cares if a lighthouse on ACK sees a gust to 65mph.......it will be like 50 mph for 95% of the region and 40mph at my house......NBD.

Looks like the better potential is weenie atrophy due to the 11th consecutive month of monotony.

wow you guys really do have the best forum

I realize this is likely light-hearted, but.....

It only appears that way to those who are unfamilar with the dynamic here and choose to qualify the character of our subforum with a random, arbitrarily chosen raunchy post, but we don't really care what most of that contigent thinks anyway; the fact remains that the majority of posters from other regions will frequent our subforum when there is a major winter storm imminent.......if you don't find our vulgar sense of humor appealing, yet fail to focus on the superior contributions of our mets and fairly adept hobbyists, then that is your loss and no one else's.

Seems like Kushy and Bowelmehunter spend quite a bit of time in our threads...wonder why?

Violently agree, If folks get offended coming in here to bad..

I can't believe we are this close and yet the NAM is still painting as much as 60-70 knots at 925mb. THe amount of QPF is also pretty incredible as well, just so much moisture being drawn into this system. The trough is just so deep the flow out ahead of it is just straight from the Gulf, just drawing boatloads of moisture up the East coast. If it wasn't for all these waves developing and occlusion going on we could have potentially seen even warmer air get advected into the region.
