Potential biggest severe outbreak of the Summer


Damage In Tolland

Recommended Posts

Looks like I picked a good time to go up to Lake Winni today.

 

Rest of region gets it as well.

 

Prepare for quite a bit of damage 

 

HIGH IMPACT WEATHER: THUNDERSTORMS MAY PRODUCE DAMAGING WINDS AND

LARGE HAIL THIS EVENING ACROSS INTERIOR WRN AND CENTRAL ME AND ALL
BUT SEACOAST AND MERRIMACK VLY NH.

LOTS OF SEVERE WX INDICATORS SHOWING UP FOR LATE TODAY AND THIS
EVENING ACROSS THE INTERIOR OF THE CWA - GOOD DYNAMIC FORCING IN
THE FORM OF HEIGHT FALLS ALOFT AND ENHANCED UVV ASSOCIATED WITH
JET ENTRY REGION. UNSTABLE ENVIRONMENT WITH GOOD SFC BASED CAPES
IN THE 1-1.5K RANGE...WHICH HOLD ON ABV NIGHTTIME INVERSION WELL
INTO THE EVENING. THE TIMING MAY NOT BE GREAT FOR DEVELOPMENT OVER
THE CWA...BUT STORMS THAT DO FROM TO OUR WEST SHOULD BE ABLE TO BE
MAINTAINED FOR SEVERAL HOURS AFTER SUNSET...AND WORK INTO NRN AND
WESTERN ZONES. WILL LKLY SEE SOME OF LINE DEVELOP OVER NY/VT AND
MOVE EWD INTO NH AND INTERIOR ME...WHICH WILL BRING THE THREAT OF
DAMAGING WINDS...AND ANY CELLS THAT DEVELOP JUST AHEAD OF THAT
LINE COULD PRODUCE ROTATING UPDRAFTS AND WILL HAVE AN ADDL LARGE
HAIL THREAT. SHOULD SEE STORMS WEAKEN LATE EVENING OR SHORTLY
AFTER MIDNIGHT...AND BEFORE THEY REACH THE COAST...SO THE THREAT
FOR ANY SEVERE WX IS MINIMAL. BUT COULD SEVERAL ROUNDS OF
CONVECTIVE SHRA IN SRN NH AND THE ME COAST THRU EARLY TUE MORNING.

From the BGM discussion this morning:  THE STEEP LAPSE RATES EXTENDING INTO THE MID LEVELS

WILL PROMOTE COLD POOLS ADVANCING AHEAD OF STORMS AND THUS GUSTY
WINDS...IN ADDITION TO THE DOWNBURST POTENTIAL DIRECTLY UNDER
CELLS.

 

I don't really understand conceptually what this means.....can someone help me out?  I think of lapse rates as a horizontal parameter so how does that get the cold pools out ahead of the storms?

Thanks.

CAPE actually increases overnight into tomorrow morning from the south. Strong winds aloft and decent lapse rates, venting from entrance region of jet...don't see why we won't have some good bangers maybe predawn into aftn depending on location.

 

I agree. Could see an impressive round of dawn-convection. Maybe some marginal hail reports and lots of CGs? Nice steepening of mid level lapse rates.

 

The question is can we recover after morning convection and do low level dews mix out?

Well NCAR ensembles say red area today, yellow area tomorrow (and average about 2,000 CAPE tomorrow across SNE, so take that Euro).

Yeah they're pretty impressive for tomorrow. Also - notice that area of convection around 6z tonight in the Springfield Mass area. Pretty decent signal for some good overnight bangers.

SPC WRF develops a nice supercell or two late night over far southern SNE. Wouldn't that be something, overnight ping pongs at Tolland, while Kevin is high and dry at the lake.

Looks like the NCAR ensembles have some supercells riding the coast east from Long Island.

 

And yes... that would be fantastic!

 

Damage in Tolland... Partly Cloudy in NH.

I have a feeling tomorrow may be best BOS-BDL and SE perhaps? Seems like GFS and NAM look good for that.
