Here is the latest outlook from the SPC:

...NEW ENGLAND AREA TODAY INTO TONIGHT...
   LOW-LEVEL MOISTURE /BOUNDARY LAYER DEWPOINTS IN THE UPPER 60S/ HAS
   SPREAD NEWD INTO NY AND SRN NEW ENGLAND...AND ADDITIONAL MOISTENING
   IS EXPECTED TODAY ACROSS NRN NEW ENGLAND TO THE S OF A STATIONARY
   FRONT ACROSS NRN MAINE.  THE PRIMARY SYNOPTIC SHORTWAVE TROUGH AND
   SURFACE CYCLONE/COLD FRONT ARE STILL WELL TO THE W IN ONTARIO...AND
   WILL LIKELY REACH MAINE TONIGHT.  THEREFORE...THE PRIMARY FOCI FOR
   CONVECTIVE DEVELOPMENT WILL BE THE STATIONARY FRONT AND WEAK
   EMBEDDED SPEED MAXIMA MOVING EWD FROM QUEBEC.
   
   FORECAST SOUNDINGS SHOW THE POTENTIAL FOR ORGANIZED SEVERE STORMS
   WITH DAMAGING WINDS AND HAIL INVOF THE STATIONARY FRONT IN
   MAINE...WHERE MLCAPE VALUES COULD REACH 1500-2000 J/KG IN
   COMBINATION WITH STRAIGHT HODOGRAPHS AND 0-6 KM BULK SHEAR NEAR 40
   KT.  FARTHER S/SW...VERTICAL SHEAR WILL BE WEAKER...BUT SCATTERED
   THUNDERSTORMS ARE STILL EXPECTED THIS AFTERNOON INVOF A WEAK
   PRE-FRONTAL TROUGH.  HERE...THE WEAKER VERTICAL SHEAR AND MODERATE
   INSTABILITY SUGGEST THAT A FEW WET MICROBURSTS SHOULD BE THE PRIMARY
   SEVERE THREAT TOWARD ERN NY STATE.

Temperatures and dew points have started to soar (see latest home page post). Convective temperature should be reached by 1pm. High dew points indicate that storms this afternoon will have a lot of moisture to work with. Torrential rainfall is possible, along with damaging winds and frequent lightning.

Stay tuned.
