August 2012 Severe Thunderstorm/Convection Discussion


earthlight

Recommended Posts

If a technically non severe storm can cause significant damage, then why do people overreact when a storm that's actually severe causes a lot more damage. Many people then complain about how worse the storms were than forecast and how they had no warning, when clearly severe thunderstorm watches and warnings described the criteria for severe storms perfectly.

If people overestimate a weaker storm, then they really blow up when a severe storm hits, even though if meets warned criteria.

There is a ton of moisture available for the storms from late tomorrow into the evening.

The best combo of shear and instability will be found the further west that you go.

The weak lapse rates may cut down on the wind potential a bit especially the further

east that you go. Though flooding will be a concern just about anywhere that you go

around the region that sees training of cells.

That is a very skinny cape...value around 580...not impressive although I think the nightime storms will be driven by elevated instability.

It looks like the South Shore beaches will be very windy before the front comes through with gusts to 30 mph

or higher, strong rip currents, and very choppy seas. The PWAT axis is really impressive for tomorrow night.

Yea looks like even though areas east of the city miss out on the severe they will still get dumped with a ton of rain.

Getting pummeled here. Small hail and unbelievable rain rates. Also had a strong wind gust as the storm came in but not sure on the exact severity of it.

Just had the best storm of the season so far here in Piscataway. Rain so heavy you could not see, and some extremely close lightning strikes. The lightning show was spectacular.

Lol...im out of town...no wonder

Lol I left New Brunswick like two hours ago to go back to Long Island for the remainder of the weekend...awesome timing! :axe:

Haven't seen hail since fall 2010. I was in New Brunswick when Nassau County had their 1-3" hail episode last summer.

I guess I can't complain considering what I saw when I went chasing last Thursday, but still...I want hail! Lol

Radar indicated strong winds (close to 60) between 406 and 445 PM EDT

from South Plainfield to Plainfield to Watchung to Madison. Could have

downed a few trees and wires. The SVR was certainly warranted. The storm

clipped Western Union/Essex counties. I call that a fringer for an NWS office

on the edge of a coverage area. Tough for Upton to warn for it, even

if it did cause minor wind damage on their side of the line, probably a good

idea not to issue a small polygon.

There was definitely a near-severe gust as the storm came through..so I can back up what you saw on the radar scans.

Surprisingly it looks like there was no rain recorded at the Rutgers weather station. I'm sure there must've been a very good lightning show at the very least though. I did see impressive cumulonimbus clouds to the south and east and heard a rumble of thunder, even from here.

I'm very close to that area outlined but I didn't see anything that could even be considered 'strong.' However I'll be heading over to Berkeley Heights in a bit which, as per radar scans, did look like was hit by some winds. I'll certainly be on the lookout for damage.

Upton bearish on the severe threat east of the hudson.

ANY STRONG TO SEVERE CONVECTION SHOULD START WEAKENING IN INTENSITY

THIS EVENING AS IT TRACKS EAST TOWARDS THE HUDSON RIVER/NYC WITH

MARITIME AIRMASS IN PLACE.

Looks like we still get the heavy rain though

NAM has heavy rain starting around 2 pm for the city and out of here by 6 or 7 tonight, and little else after that...clearly off as there is no way the area is getting doused in the next 20 minutes...so we have no idea whats going to happen later...
