Yeah RUC has winds very backed in metro NYC and areas northeast into SNE which enhances tornado threat. Will be interesting to see what SPC does at 1630.

Strongly agreed...I woke up about an hour ago (slept in on the wrong day) and was very impressed with what im looking at especially on the RUC and the latest mesoanalysis.

The mid level lapse rates are very impressive for this area and this time of year..over 8-8.5 down towards Southeast New York & New York City. The degree of surface based instability juxtaposed with favorable effective bulk shear and backing winds on the RUC is certainly concerning. The most favorable area for discrete supercells is likely from Southern VY southward through Western SNE and Eastern NY extending southwest towards Northern NJ and NYC.

It's been a while since I've seen decent 0-1km SRH and EHI parameters forecast in this part of the country in conjunction with moderate to high instability & a favorable EML in place.

A little uneasy about the storms west of BGM having a really tough time maintaining updrafts given the fact parameters there look favorable.

It's certainly interesting. They are riding on the periphery of around ~35 kts of 0-6km bulk shear and 200 m2/s2 of 0-3km SRH. There's 5000+ j/kg of SBCAPE to the east/southeast of those updrafts, too.

There's still a cap at the base of that EML. That's the issue here I think.

Could very well be. The EML is doing it's work right now over Central PA...check out the surface based CAPE on the mesoanalysis in juxtaposition with mid level lapse rates around 8 and approaching favorable bulk shear...5000+ j/kg right now at the 15z analysis.

Well in a terribly boring period like June I guess it's worth keeping an eye on days like today. But in general ...devoting much time on severe wx around here is comparable to a die-hard weenie tracking all the potential snowstorms for Atlanta. Even if it happens that someone does get an F1 tornado, it will be our equivalent of the 4 inch blizzard in ATL while ORH gets 28" from the same storm.

They are laughing at us...

OT but this is down right fascinating: that MCS that moved through the Midwest and off our coast yesterday turned S and is circumnavigating the ridge, but is taking on tropical characteristics...

TROPICAL WEATHER OUTLOOK

NWS NATIONAL HURRICANE CENTER MIAMI FL

800 AM EDT WED JUN 1 2011

FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO...

1. A SMALL AREA OF LOW PRESSURE LOCATED ABOUT 200 MILES EAST OF

JACKSONVILLE FLORIDA IS MOVING WEST-SOUTHWESTWARD AT AROUND 20 MPH.

THE LOW CONTINUES TO PRODUCE A CONCENTRATED AREA OF SHOWERS AND

THUNDERSTORMS...AND ENVIRONMENTAL CONDITIONS ARE MARGINALLY

FAVORABLE FOR SOME DEVELOPMENT OF THIS SYSTEM BEFORE IT MOVES OVER

NORTHERN FLORIDA LATER TODAY. REGARDLESS OF DEVELOPMENT...THIS

DISTURBANCE COULD PRODUCE LOCALLY HEAVY RAINFALL AND STRONG GUSTY

WINDS OVER PORTIONS OF THE FLORIDA PENINSULA. THERE IS A MEDIUM

CHANCE...30 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE

DURING THE NEXT 48 HOURS. FOR ADDITIONAL INFORMATION ON THIS

SYSTEM...PLEASE SEE PRODUCTS FROM YOUR LOCAL NATIONAL WEATHER

SERVICE OFFICE.
