Yeah it's possible. Recall on June 1st after he first line of cells went through, we had that awesome light show develop in the evening.

BOX looks like they agree with the late aftn/evening with better dynamics.Just gotta have to wait and see.

ALL FACTORS CONSIDERED...FEELING IS THERE WILL STILL BE TWO WAVES

OF CONVECTION. /FIRST/ WITH THE MCS INTO THIS EARLY AFTN...ALONG

AND AHEAD OF WHICH CONVECTION WILL BLOSSOM WITH THE

DESTABILIZATION AND LIFT OF THE SFC BOUNDARY LAYER. CANT RULE OUT

ISOLATED THREATS OF HEAVY RAINFALL...SMALL HAIL AND DAMAGING

WINDS. THE SITUATED WILL NEED TO BE MONITORED CLOSELY. /SECOND/

ALONG AND AHEAD OF THE SFC COLD FRONT POISED SE OF THE ST LAWRENCE

VLY RGN...TEMPS AND DEWPOINTS ARE REBOUNDING BEHIND THE MCS OVER

THE ERN GRT LKS RGN. VISIBLE SATELLITE TRENDS DO HIGHLIGHT SOME

CLEARING WHICH SHOULD ACT TO AID THE DESTABILIZATION OF THE SFC

BOUNDARY LAYER...BUT THIS WILL HAVE TO BE CLOSELY MONITORED. FEEL

THIS WILL BE THE MAIN SHOW OF THREATS FOR THIS LATER AFTN INTO

EVNG...WITH THE ANTICIPATION OF DAMAGING WINDS...SMALL HAIL...

HEAVY RAIN AND LOCALIZED FLOODING...FREQUENT LIGHTNING...AND THE

ISOLATED POSSIBILITY OF TORNADOES.

AFOREMENTIONED SHEAR PROFILES CONTINUE TO SUPPORT MULTICELL

CLUSTERS AND LEWPS...BUT WITH S/SW SFC FLOW AND FAST MID-LVL FLOW

OUT OF THE W/NW...COUPLED WITH SHEAR ORTHOGONAL TO THE SFC COLD

FRONT...SUPERCELLS WITH ISOLATED TORNADOES CANT BE RULED OUT PER

SPC DAY 1 OUTLOOK.

LIKELY TO SEE STRONG STORMS INTO THE MIDDAY AND INTO THE EARLY

AFTN PERIOD WITH THIS FIRST LINE...AFTER WHICH A LULL MAY OCCUR

THRU AFTN...WHENCE BY LATE AFTN WE SHOULD START TO SEE THE SECOND

WAVE ALONG AND AHEAD OF THE SFC COLD FRONT WITH THE PRIMARY SEVERE

Idk what you guys are talking about but the suns been.blaring.here all day and its 85 lol

The first round of showers needs to clear up fast do we can spike the instability with sunshine and fire storms in the pm time . your morning sun will just get erased when those showers work in

drove through that storm in Windham/Londonderry. Heavy rain and some wind, nothing spectuacular. Nice cloud formations though. It was around 90 in Gov't Ctr and Downtown, 71 here.

It was pretty good here too.. probably the best storm well see all day here.. hopefully not tho.. its.actually starting to clear up now to the west!

FARTHER S...MORNING CONVECTION IS

WEAKENING ACROSS SE NY/MA...BUT SUBSTANTIAL DEBRIS CLOUDS WILL

LIKELY REMAIN DURING THE DAY ACROSS NEW ENGLAND. REGIONAL 12Z

SOUNDINGS SHOW POOR LAPSE RATES ALOFT...AND THE STRONGER INSTABILITY

IS LARGELY CONFINED TO AREAS FROM THE UPPER OH VALLEY WWD. THERE

WILL BE SOME DESTABILIZATION ACROSS SRN NEW ENGLAND IN ADVANCE OF

THE WEAKENING CONVECTION...AND ACROSS WRN/CENTRAL PA IN ADVANCE OF A

CONVECTIVELY ENHANCED VORT MAX MOVING SEWD OVER LAKE ERIE. SOME

INCREASE IN STORM COVERAGE/INTENSITY IS EXPECTED THIS AFTERNOON FROM

PA TO SRN NEW ENGLAND...WHERE MLCAPE WILL RANGE FROM 500-1000 J/KG

ACROSS SE NEW ENGLAND TO 1500 J/KG ACROSS CENTRAL/WRN PA. LARGELY

UNIDIRECTIONAL PROFILES WITH DEEP-LAYER WNWLY/NWLY SHEAR COULD

SUPPORT A FEW ORGANIZED CLUSTERS/LINE SEGMENTS CAPABLE OF PRODUCING

DAMAGING WINDS.
