Potential significant severe weather Wednesday

Recommended Posts

Its usually more common for the shear to be too strong with lacking instability...I think generally too much CAPE and lesser shear is not as much an inhibitor.

Very true. The pulsing nature of these cells though is suggesting to me that these storms are notseperating downdrfat from updraft very well right now.

The very high BRN numbers over Central NJ suggest maybe so:

Was going to post that map, >100 I'd think is way too much BRN.

I wonder what the major networks/evening news will do at 5pm with this tornado watch. Choppers flying over a hazy sky, saying it looks ominous, while Lonnie Quinn gives advice on what to do if a tornado strikes, and the naive anchors bound to summon Joplin into their conscience while a radar map of dissipating storms are shown...

Upton's giving up:

VERY NON IMPRESSIVE RADAR PRESENTATION LOCALLY GIVEN ALL THE INSTABILITY. TORNADO WATCH REMAINS IN EFFECT UNTIL 8 PM...BUT EXPECT THAT IT CAN BE CANCELLED EARLY FROM WEST TO EAST. APPEARS THE LACK OF SHEAR AND DYNAMICS HAS PREVENTED THE ANTICIPATED MORE EXTENSIVE DEVELOPMENT. ANVIL OVER N JERSEY AND LOWER HUDSON VALLEY AS OF 19Z WILL ALSO HELP CAP NEW CONVECTION. POPS HAVE BEEN LOWERED TO SCATTERED.

As I stated earlier, nice to seem them taking initiative over SPC.

I don't know if we're done yet....front is still back in central PA, plenty of time.

Sun just came back out, 86.3/76 and rising. Incredibly oppressive outside, feels like we couldn't help but have a severe t-storm right now.

MESOSCALE DISCUSSION 1053

NWS STORM PREDICTION CENTER NORMAN OK

0317 PM CDT WED JUN 01 2011

AREAS AFFECTED...ME...NH...SRN VT...MA...CT...RI...SE NY...NY CITY

CONCERNING...TORNADO WATCH 411...413...

VALID 012017Z - 012145Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 411...413...CONTINUES.

A THREAT FOR TORNADOES...LARGE HAIL AND WIND DAMAGE WILL CONTINUE

ACROSS TORNADO WATCH 411 AND 413 THIS AFTERNOON INTO THE EARLY

EVENING.

SEVERAL WELL-DEVELOPED SUPERCELLS ARE ONGOING FROM NRN MAINE SWD

ACROSS THE WRN PART OF MAINE ALONG AN AXIS OF STRONG INSTABILITY.

THIS AREA IS LOCATED TO THE EXIT REGION OF THE MID-LEVEL JET IN AN

AREA WITH STRONG LOW-LEVEL SHEAR. THE WSR-88D VWP AT PORTLAND MAINE

HAS A 0-3 KM STORM RELATIVE HELICITY OF 350 TO 400 M2/S2. THIS IS

CREATING A FAVORABLE ENVIRONMENT FOR SUPERCELLS WITH WELL-DEVELOPED

LOW-LEVEL MESOCYCLONES. AS THE SUPERCELLS MOVE ACROSS THE STRONGLY

UNSTABLE AIRMASS IN CNTRL MAINE...TORNADOES...WIND DAMAGE AND LARGE

HAIL WILL BE POSSIBLE WITH THE MORE INTENSE STORMS.

FURTHER TO THE SOUTH...SEVERAL VERY INTENSE STORMS ARE ONGOING

ACROSS MA AND NRN CT. THIS ACTIVITY IS LOCATED JUST TO THE NORTHEAST

OF A MAX OF STRONG INSTABILITY WITH MESOANALYSIS SHOWING MLCAPE

VALUES IN THE 3000 TO 4000 J/KG. THIS ALONG WITH 45 TO 50 KT OF DEEP

LAYER SHEAR WILL SUPPORT WELL-DEVELOPED SUPERCELLS WITH A THREAT OF

TORNADOES AND LARGE HAIL. WIND DAMAGE WILL ALSO BE LIKELY ESPECIALLY

IF SEVERAL OF THE STORMS CAN ORGANIZE INTO A LINE.

SPC continues to be 5 times more bullish than Upton. :whistle:

Airmass is just incredibly juiced now, 86/78 here, rarely see dewpoints so high.

We need a severe storm from this horrid airmass. I'm hoping something pops from those cells in NJ, although the highest CAPE is in W NJ with values up to 6000J/kg. CAPE starts to decrease as you approach the maritime-influenced environment of NYC.

NWS has a low of 48F here tomorrow night. Going to feel great as we only have one room with AC in the entire house, can't wait to shut it off and open the windows to a refreshing, crisp breeze. But first, we need storms. Is it possible we see a linear squall line with the cold front later tonight as well as the discrete supercells that have been popping up in Massachusetts and NJ?
