AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
220 PM EDT TUE JUN 23 1998

17Z. LOCAL SFC MESO ANALYSIS SHOWS THETA-E RIDGE(>345 DEG K) FROM
BGM-SYR-BTV AND STRONG MOIST CONVERGENCE BULLSEYE OVER ELM WHERE
STRONGEST CELL IS NOW. ANOTHER WEAKER CONVERGENCE CENTER OVER NE NY.
BEST INSTABILITY(-3 TO -5 SBLI/MIXED BOUNDARY LAYER OVERALL BTV CWA
EXCEPT LOWER CT VALLEY WHERE AIRMASS MORE MARTIME AND STABLE.
MORNING SOUNDING AT ALY/GYX SHOWS PRECIP WATER NEARLY 1.7 WHILE ONLY
NEAR 1 INCH AT WMW IN DRIER AIRMASS. WV LOOP SHOWS WELL DEVELOPED
SHORTWAVE MOVING STEADILY EAST WITH NY/VT UNDER BAROCLINIC LEAF.
SO EVEN THOUGH STORMS WILL MOVE, LOCALLY 2+ INCHES OF RAIN ARE
POSSIBLE. THIS ALREADY EVIDENT WITH CELL NEAR BGM PER KTYX
ESTIMATES. NOT TOO CONCERNED WITH SEVERE BUT VWP SHOWS 30-40 KTS OF
WIND AT 18 K FEET WITH VERY LITTLE SHEAR BELOW. SO WILL HAVE TO
WATCH. INHIBITING FACTOR IS AC/AS CLOUD DECK WITH SHOWERS NOW MOVING
INTO ST. LAW VALLEY THAT IS COOLING LOW LEVELS. SO BEST CHANCE OF
STRONGER CONVECTION APPEARS ART-BTV AND SOUTH. LOTS OF SHOWERS AND
THUNDER A POSSIBILITY THROUGH ABOUT MIDNIGHT SO BELIEVE HIGHER AVN
POPS ARE WARRENTED.

TROF SHOULD MOVE THROUGH THE REGION TONIGHT LEAVING LOTS OF LOW
CLOUDS AND AREAS OF FOG. LOW TEMPS IN THE 60S.

SOME OVERALL DRYING EVIDENT ON MODELS AS UPPER RIDGE BUILDS INTO THE
AREA WED/THU.  POPS LOW ON BOTH MODELS SO PREVIOUS FORECAST/EXTENDED
WITH MOSTLY SUNNY LOOKS GOOD. HUMIDITY SHOULD BE A BIT LOWER THAN
THAT OF TODAY/YESTERDAY. SEASONABLE TEMPS WITH HIGHS IN THE 80S AND
LOWS AROUND 60.
