Finally...I'm getting tingles as my fingers stroke the keyboard typing this up. Intense tingles...just like the intense updrafts that will be plowing through the troposphere this weekend headed towards the stratosphere before the EL smacks them short.
Low pressure associated with a fairly strong shortwave progresses slowly through southeast Canada over the weekend. As this strengthens we see an increase in winds aloft with 500mb winds in excess of 30-50 knots. At the surface a warm and humid airmass with sfc temperatures at least into the 80's with dewpoints into the 60's. Steeper mid-level lapse rates associated with the energy will help to contribute to MLCAPE values approaching 1500 J/KG both days...perhaps near 2,000 depending on degree of sfc heating.
Given sufficient wind shear aloft, the main severe threat will be damaging winds, however, an early look at forecast soundings indicate straight and long hodographs. This would suggest splitting cells with an accompanied risk for large hail.
Saturday looks to feature numerous t'storms from NY into northern New England...with the potential for the evolution of an MCS which could come with the threat for widespread damaging winds. Activity should persist into at least western sections of New England before beginning to diminish, however, activity may push through much of the region. The damaging wind threat could extend into MA should an MCS evolve (MA and southern NH).
Sunday is a wildcard as it will all be dependent on cloud debris, however, strong shear and potential for sufficient CAPE will be there.
FINALLY SOMETHING TO TRACK!!!!
