Summer 2015 General Thunderstorm Thread

Recommended Posts

Figured it is time to start this thread.  Really think Wiz should be the one to start it, but going to need somewhere to talk about it if these storms fire.

 

First Severe Watch possible.

 

 MESOSCALE DISCUSSION 0801
   NWS STORM PREDICTION CENTER NORMAN OK
   1050 AM CDT WED MAY 27 2015

   AREAS AFFECTED...PORTIONS OF UPSTATE NY ACROSS THE HUDSON AND
   CHAMPLAIN VALLEYS THROUGH VT

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 271550Z - 271715Z

   PROBABILITY OF WATCH ISSUANCE...60 PERCENT

   SUMMARY...RISK FOR LOCALLY DAMAGING WINDS AND MARGINAL HAIL WILL
   INCREASE OVER THE NEXT COUPLE OF HOURS AS STORMS INCREASE ACROSS
   THIS AREA.  WW POSSIBLE.

   DISCUSSION...LATEST SURFACE ANALYSIS SHOWS A WEAK N-S CONFLUENCE
   AXIS/TROUGH ACROSS ERN NY JUST W OF THE CHAMPLAIN AND HUDSON
   VALLEYS...WITH HEATING/DESTABILIZATION OF THE PRE-EXISTING MOIST
   BOUNDARY LAYER /MID 60S DEWPOINTS/ UNDERWAY ALONG THIS AXIS. 
   VISIBLE SATELLITE SHOWS AN INCREASE IN SCATTERED TCU/CB ACROSS THIS
   AREA...WITH A FEW STRONGER CELLS -- A FEW NOW PRODUCING LIGHTNING --
   INDICATED IN THE LATEST RADAR AND LIGHTNING LOOPS.

   MORNING ALB RAOB AND LATEST AREA WSR-88D VWPS REVEAL WEAKLY
   VEERING/STRENGTHENING FLOW WITH HEIGHT -- SUFFICIENT FOR
   ORGANIZED/ROTATING UPDRAFTS.  AS LARGE-SCALE ASCENT GRADUALLY
   INCREASES ACROSS THIS AREA AS HEIGHT FALLS OVERSPREAD THE REGION
   AHEAD OF THE SHORT-WAVE TROUGH...ADDITIONAL AIRMASS DESTABILIZATION
   WILL SUPPORT A STEADY INCREASE IN CONVECTIVE COVERAGE/INTENSITY. 
   RELATIVELY WEAK LAPSE RATES SHOULD LIMIT OVERALL HAIL RISK...BUT
   LOCALLY DAMAGING WINDS WILL BECOME INCREASINGLY LIKELY INTO THE
   EARLY AFTERNOON HOURS.

Haha.  You golfing today?  Might be an interesting afternoon on the links.

 

Nope, Tuesdays and Thursdays are my golf nights.  Wednesdays are usually lawn mowing nights, that may get postponed.

I don't think the heavy stuff's gonna come down for quite awhile

Whenever we get a bit of weather when golfing someone throws this line out.

Hammertime in VT and Western Mass today. Could see picnic tables blown off mountain tops..and Pony tails ripped off heads

 

tomorrow probably just Jersey to NW CT

 

Dew the dew... lots of 70F Td's showing up in VT now.

 

Pretty good moisture pooling just ahead of the boundary in the Champlain Valley and northern VT with 66-72F dews.  That stuff in the Adirondacks should really explode when it hits the juice of the Champlain Valley this time of year.

So many folks in good moods enjoying this wx. Def good vibes and deep summer among the populace. Got my first 70 dew today as well. Hit 71 earlier. Now 69.

Enjoy the storms

Another MD from SPC...sneaking towards CT and the Berks.

 

MESOSCALE DISCUSSION 0803
   NWS STORM PREDICTION CENTER NORMAN OK
   1121 AM CDT WED MAY 27 2015

   AREAS AFFECTED...THE CATSKILLS/LOWER HUDSON VALLEY AREA SSWWD ACROSS
   WRN NJ/ERN PA INTO MD/NRN VA

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 271621Z - 271715Z

   PROBABILITY OF WATCH ISSUANCE...60 PERCENT

   SUMMARY...SEVERE RISK TO INCREASE AS STORMS ORGANIZE OVER THE NEXT
   1-2 HOURS.  WW ISSUANCE MAY BE NEEDED IN THE NEXT HOUR OR SO.

   DISCUSSION...LATEST RADAR LOOP SHOWS AN INCREASE IN CONVECTION FROM
   ERN PA SWD INTO NWRN VA ATTM...AHEAD OF ONGOING/WEAK PRECIPITATION
   BAND CROSSING THE APPALACHIANS AND INVOF AN ASSOCIATED/NNE-SSW
   SURFACE TROUGH.  HEATING OF THE MOIST BOUNDARY LAYER /60S TO LOW 70S
   DEWPOINTS/ HAS YIELDED AN AXIS OF 1000 J/KG MIXED-LAYER CAPE AHEAD
   OF THE DEVELOPING CONVECTION PER OBJECTIVE ANALYSIS...AND FURTHER
   DESTABILIZATION WILL SUPPORT CONTINUED CONVECTIVE INCREASE -- BOTH
   IN TERMS OF COVERAGE AND INTENSITY.  STRONGER FLOW ALOFT WILL REMAIN
   ACROSS NRN PORTIONS OF THE AREA -- WHERE RISK FOR LOCALLY DAMAGING
   WINDS WILL INCREASE IN THE NEAR TERM.  HOWEVER...A MORE MOIST
   BOUNDARY LAYER -- AND THUS GREATER DESTABILIZATION POTENTIAL --
   FARTHER S MAY PARTIALLY OFFSET THE SOMEWHAT WEAKER KINEMATICS TO
   SUPPORT SEVERE RISK AS FAR S AS THE DC METRO AREA.

Only reason this is acceptable is because of the threat of storms, haha.  It does have that feel of storms though...hazy sun, hot, very humid, breezy out of the south like something is approaching.  Lets just avoid acres of straightline blow down on the mountain though.  No more natural mowing down of prime ski terrain.

If you could send or direct a blow down here in Tolland this summer, I would be in eternal debt to you.

Lakes region winning...at least nrn part.  Dendrite downpour en-route?

Not looking great so far...I'm going to need some redevelopment on the southern side of that line segment around I89. Hopefully I get something...even a tenth would be appreciated.
