LOW PRES MOVG FM NR SBN EWRD ALG THE SRN SHORE OF LERI THIS EVE WL
PULL A CDFNT TRAILING THE LOW SE ACRS INLAND AREAS FIRST HALF OF
TNGT.  UNSTBL AMS AND SUPPORTING GUD WND SHEAR WL LEAD TO POTENTIAL
FOR STG TO LOCALLY SVR TSRA.  WNDS GUSTING TO 50KT OR MORE ARE
POSSIBLE LATE THIS AFTN THRU EVE. TRYING TO TIME WHEN AND WHERE TSRA
WL OCCUR WL BE TOUGH AS DYNAMICS MAY ALLOW FOR CONVECTION TO DVLP
ALMOST ANYWHERE BUT AT TAF ISSUE TIME WL TRY AND BEST REFLECT SOME
TYPE OF TIMING FM NW TO SE DUE TO PASSAGE OF LOW AND CDFNT. LLVL
MSTR IS SHOWN TO RMN WIDESPREAD OVR AREA LATE TNGT INTO WED MORN
WITH GUIDANCE HINTING AT LOW STRATUS CLDS VERSUS FOG AS WNDS STAY UP
ENUF TO LEAN THE BALANCE TOWARD MORE STRATUS THAN FOG. WL TAKE A
STAB AND GO FOR CIGS OF HI END IFR DURG THIS PD AS THE SHALLOW COOL

.SHORT TERM/TODAY THROUGH WEDNESDAY NIGHT/...
WARM FRONT ACROSS SRN OH WILL BE MAJOR WX MAKER TDA WITH POTENTIAL
FOR SOME DECENT STORMS LATER IN THE DAY. FIRST THINGS FIRST
THO...LINE OF CONVECTION CONTS TO STRETCH FROM NERN OH ACROSS LERI
AND INTO LOWER MI.  HAS BEEN A SLIGHT DECREASE IN INTENSITY OF THIS
ACTIVITY AND IT APPEARS TO BE SHIFTING OFF TO THE ENE EVER SO
SLOWLY.  AT ANY RATE EXPECT MOST OF IT TO BE GONE BY 12Z OR SO.
SOME MODEL DIFFS TODAY WITH MOVEMENT OF SFC LOW ACROSS NRN OH.  GFS
IS VERY FAST WITH THIS FEATURE WHILE NAM REMAINS SLOWER AND MUCH
MORE CONSISTENT.  GIVEN FLOW ALOFT FEEL NAM MAY BE THE WAY TO GO
TODAY.  WARM FRONT FROM THIS LOW WILL MOVE N ACROSS FORECAST AREA
THIS AFT.  MODELS CONTINUE TO OVERDUE SFC MOISTURE AND PROGS OF SFC
DEWPOINTS IN THE LOW 60S AT 18Z OBVIOUSLY OVERDONE GIVEN FACT YOU
HAVE TO GO AS FAR SW AS ARKANSAS TO FIND SIMILAR DEWPOINTS.  WITH
THAT SAID...FORECASTS OF INSTABILITY AND CAPE TODAY BY BUKFIT ARE
ALSO A LITTLE OVERDONE.  BUT...GIVEN FAIRLY DECENT STRAIT LINE SHEAR
DO EXPECT TSRA TO GET GOING AS FRONT APPROACHES.  COULD BE A FEW
SUPERCELLS TODAY BUT STEEP LAPSE RATES AND FAIRLY UNIDIRECTIONAL
SHEAR PROFILES SUGGEST MORE OF A DAMAGING WIND/LARGE HAIL EPISODE
THIS AFT.  SO...WILL CONT WITH LIKELY WORDING TODAY ALL AREAS AND IN
THE E TONIGHT.  HAVE ADDED SEVERE WORDING TO GRIDS GIVEN SLIGHT RISK
FROM SPC.  TEMPS COULD BE TRICKY TODAY WITH LOW 80S IN THE S AND
UPPER 50S IN NW PA.  DAY CREW WILL HAVE TO WATCH SRN AREAS THIS AFT
AS TEMPS IN SRN OH YDAY WERE VERY WARM.  PRECIP SHOULD WIND DOWN
FROM NW TO SE TONIGHT AS SFC LOW MOVES INTO CENTRAL PA.  DRY AND
RELATIVELY COOL WEATHER FOR THE MIDDLE OF THE WEEK.
