Severe Weather potential 9/8/12

Welcome to New England! You'll radiate pretty nicely there in North Adams, I think. You'll get shadowed a bit come snow season, but the temps will make up for it.

It's already pretty sunny, but there's some pretty nasty storms way west of us, and the sun is peaking in and out. We just did a huge shop last night and I hope nothing goes bad. This moderate risk really came out of nowhere, as I have been busy with school and whatnot.

Solid cloud deck here now.

Getting more in the way of clouds here but still a decent amount of breaks and sun. Seems like as llvl moisture continues to increase along with moisture convergence starting to get more in the way of clouds to develop.

9 am obs from the hud valley area.

HUDSON VALLEY

CITY SKY/WX TMP DP RH WIND PRES REMARKS

NEWBURGH PTSUNNY 73 70 88 S9 29.79F

ALBANY CLOUDY 73 64 73 S25G35 29.72F

I remember a couple of times where we had a few spinups and there was cloud cover most of the day. The sun is a big factor but we have the other factors in place to help overcome.

Man already sustained winds near 30mph out of the south on the BTV shore, and 50-60mph at 3Kft working across Adirondacks...not going to take much to mix down 50kts at 3000ft.

"South winds already sustained 26 kts at Colchester Reef and will increase areawide through late this morning. Also noted 50 kts at 3 kft on ktyx VAD past few hours...indicative of very strong wind fields moving in from the west. Isolated storms possible across northern New York...moving rapidly northeastward around 50 kts. Main action for late this afternoon/evening will evolve from activity currently extending from near buf southward through western PA. This is associated with linear forcing associated with vigorous upper trough over Ohio. Good moisture surge noted across southeastern New York/CT with low 70s dewpoints. Looks like everything is on track to come together. "

The dynamics are just so potent today we really don't need alot of sun at all. Obviously the more we get the bigger the bonus. Here it's 76F as of 9 AM...with the sun we've had and look to continue to get we could get well into the 80's.

Happened before with several Fall type systems...

one of the biggest issues for getting a derecho classification will be that the area under risk is not much larger than the minimum criteria for the wind swath.. .so you're going to need to maximize potential immediately then run the gamut.

Think I might try a storm chase today, have a fully charged phone, gassed up car and radarscope on my samsung galaxy nexus.

I would guess 84 west just over the CT/NY border would be a good place to start.

not going ot be an easy day to chase with motions. basically plant yourself out ahead and hope you're in the right spot then watch it leave you behind.

Only positive posts allowed.

like usual...

but to be clear i've not belittled the event at all really. just questioned a few smaller details. and wondered why ct blizz is still such a bad poster. :P

I still think this is more ALB and Hudson valley on west, but I could see some SVR spill into the Berks and maybe western CT. Then as second s/w approaches, I could see a flare up over areas like RI or SE MA and the Cape very late overnight. Maybe if that pre-frontal like develops and races east..the action could be further east....but not sure about that.

Welcome to New England! You'll radiate pretty nicely there in North Adams, I think. You'll get shadowed a bit come snow season, but the temps will make up for it.

North Adams Airport (AQW) is a great radiational cooling spot and will often be colder than Pittsfield Airport (PSF) by several degrees even though Pittsfield is quite a bit higher. Yes, North Adams does get shadowed quite a bit in winter synoptic snow situations as winds with an easterly component downslope quite a bit there. Regardless, the seasonal average (probably about 65" right in town) will be quite a bit higher than Chicago.

Not too sunny here with a lot of low level clouds zipping from SSE to NNW. While this is representative of good wind shear, the clouds will reduce surfacing heating and instability some if they persist. The lapse rates on the Albany, NY sounding also leave a lot to be desired. I think the convection will primarily be in the form of a low-topped squall line capable of wind damage and maybe a few discrete cells out ahead. The cells out ahead of the main line can be especially dangerous if some manage to get going due to the wind shear. Hail will not be much of a threat today as the freezing level is way up near 600 mb. Too bad we don't have a nice EML overhead. If we did, then we'd be in for a historic day of large rotating supercells. At least some of the synoptic scale forcing may help to overcome the less than stellar instability.

Got to be honest my friends. I am still not sold. Yes places west of say Springfield have a good chance, but the best chance still resides in New York State. I agree the line will survive all the way to the coast. But I just don't think it will be anything spectacular by the time it reaches most of us. The latest run of the Millersville WRF is almost kind of disheartening. It breaks the line up into pieces by the time it gets here. And the Millersville WRF is usually convectively happy. So this is something to watch.

I should add that even though we don't have terrific instability, low topped supercells are certainly capable of spinning a tornado up, especially given good wind shear. I wonder if SPC will go with a Tornado Watch for the area based on this idea.

The funneling of the winds through the N to S oriented Hudson, Berkshire, and Connecticut Valleys can add to the total wind shear by increasing both the speed shear and directional shear. In addition, the stronger winds can also enhance the advection of higher dew points and temperatures from the south. There's a reason why a lot of the historic tornadoes of W NE and E NY have occurred in the valleys.
