June 2nd Thunder Discussion

We should see a fairly active PM as a strong cold front and near record cold mid-level temps approach by Sunday night. SW flow will likely stick a fork in  stronger storms over much of E/SE areas but there may be enough elevated instability and forcing to maintain a few storms there as well. Severe threat seems pretty low overall.

Spc is pretty gung-ho all things considered. 

   ...Northeast/Mid Atlantic...
   A longwave upper trough will deepen over the Northeast and Mid
   Atlantic on Sunday, as individual vorticity maxima rotate through
   the mean trough position. A surface low should deepen and move
   northeastward across southern Quebec during the afternoon, as a
   trailing cold front sweeps through the Northeast/Mid Atlantic during
   the afternoon and evening. While cloud cover from weakening
   overnight convection may tend to limit insolation over portions of
   the area, sufficient heating and low-level moisture (dewpoints in
   the mid 50s to lower 60s F) should result in the development of
   moderate buoyancy in advance of the cold front by afternoon.
   Effective shear of 35-45 kt will support some organized structures;
   linear modes are most likely given that the primary focusing
   mechanism will be along the cold front, though any pre-frontal
   development will have some supercell potential. Damaging wind will
   likely be the primary threat, though any discrete storms will also
   have some potential for hail and perhaps a tornado.

I can always hope...

I bought a lightning detection add-on board for an Arduino microcontroller last year and never did get it operational. Had a few storms go by, but no response from the board that I could identify as representing a lightning strike.

Maybe I should hook it up again ahead of potential fireworks later today.

"western" new england is very fortuitously avoiding this cloud contamination. 

They have a 100 mile by roughly 100 mile sky light they're using to generate some SB CAPE out that way ...

Seen this more times than can be counted over the years... where the curse of the Southern New England peninsula pans a cloud deck that appears to be almost be disconnected from weather charts..  Although in this case, there's a definitive near coastal low that's apparently set up this deform band of clouds over eastern regions.  I'm not sure looking at various modeling ...that happenstance factor was really modeled too well.   I suspect it wasn't?  Most forecasts I heard formulated spoke of partial sun during the morning ... which so far is a pretty clear over-assessment.   Sky is brightening though...and sat does show some schisms beginning to crack through so perhaps we'll get a murk recovery going.

Thinking of going near Keene...like Swanzey area...about a mile south of Keene. Excellent wide open view to the west

Another great spot. Why not make the quick hike up Monadnock? lol

Goshen Fire Tower in DAR is another amazing spot. They actually still have an amazing scar trail from an F1/F2 from a few years ago through the park.

Likely going to SW NH this afternoon! First storm chase of the season 

Would that be at the airport, or at the fairgrounds, or somewhere else?

(I had a second home outside of Keene in the small town of Nelson a few years back, and explored the area quite a bit, but somehow never thought to go looking for good thunderstorm observation locations.)
