DISCUSSION
AS OF 514 AM EDT WEDNESDAY...
KEY MESSAGE 1: STRONG TO SEVERE THUNDERSTORMS HAVE CLEARED THE
REGION. WE CONCLUDE A NIGHT THAT FEATURED A DANGEROUS STORM IN
ST. LAWRENCE COUNTY THAT DROPPED BASEBALL-SIZED HAIL AND A FEW
STORMS THAT MANAGED TO PRODUCE WIND DAMAGE WITHIN BOWING
SEGMENTS, PARTICULARLY ACROSS SOUTH-CENTRAL VERMONT. THINGS ARE
QUIETER NOW, ESPECIALLY ON ACCOUNT OF THE LARGE AMOUNT OF
LIGHTNING ON DISPLAY WITH THE OVERNIGHT CONVECTION. A FEW
SHOWERS ARE LINGERING AS THEY APPROACH THE ADIRONDACKS WITH A
FEW SPOTS IN EASTERN VERMONT WITHOUT LIGHTNING. AS ALWAYS, WE
APPRECIATE REPORTS, AS THEY HELP US GET A SCOPE ON THE IMPACTS
OF THE EVENT.
KEY MESSAGE 2: WILDFIRE SMOKE WILL MOVE BACK INTO THE REGION LATE
WEDNESDAY AFTERNOON AND OVERNIGHT, SPREADING ACROSS VERMONT AND
NORTHERN NEW YORK INTO THURSDAY. POOR AIR QUALITY WILL BE POSSIBLE,
BUT TEMPERATURES WILL BE IN THE UPPER 70S TO MID 80S FOR THE MOST
PART. WITH DIURNAL HEATING, SOME SHOWERS AND STORMS WILL DEVELOP
ALONG THE COLD FRONT SHIFTING SOUTH, BUT IT WILL NOT HAVE NEARLY AS
MUCH INSTABILITY AS THIS EVENING'S ACTIVITY. COOLER CONDITIONS ENSUE.
KEY MESSAGE 3: LONGWAVE TROUGHING WILL CROSS THE REGION THIS WEEKEND AS
TWO SURFACE LOW PRESSURES, ONE IN THE GREAT LAKES AND ONE ALONG THE
MID-ATLANTIC COAST, WILL INTERACT WHILE TRACKING THROUGH THE
NORTHEAST. GLOBAL DETERMINISTIC MODELS ARE FAIRLY ALIGNED IN THIS
IDEA AT THE MOMENT, PROVIDING INCREASED CONFIDENCE OF SHOWERS AND
THUNDERSTORMS SATURDAY AFTERNOON INTO EARLY SUNDAY MORNING. THE
PROBABILITY OF AN INCH OF RAINFALL WITHIN 24 HOURS FROM THIS SYSTEM
IS AROUND 5-20%. MORE LIKELY 24 HOUR AMOUNTS WILL FALL SOMEWHERE
BETWEEN 0.33 AND 0.66 INCHES. DEPENDING ON THE STORM TRACK AND
TIMING OF ANY ASSOCIATED FRONTAL PASSAGES, THE THREAT OF STRONG TO
SEVERE STORMS WILL BE WATCHED, BUT THE THREAT SHOULD REMAIN ON THE
LOWER SIDE DUE TO A COOLER AND LESS HUMID AIRMASS. TEMPERATURES WILL
REMAIN AROUND SEASONAL NORMALS IN THE MID 70S TO LOWER 80S BOTH
SATURDAY AND SUNDAY WITH NIGHTTIME LOWS IN THE UPPER 40S TO LOWER
60S. NEXT WEEK SHOULD START BRIEFLY DRY ON MONDAY WITH TEMPERATURES
INCREASING INTO THE UPPER 70S AND 80S, THEN ANOTHER TROUGH AND
NORTHERN STREAM LOW PRESSURE SWING THROUGH TO INCREASE CHANCE OF
PRECIPITATION AGAIN ON TUESDAY.
AVIATION /06Z WEDNESDAY THROUGH SUNDAY/
THROUGH 06Z THURSDAY...SCATTERED STORMS WILL MOVE THROUGH THE REGION
DURING THE NEXT FEW HOURS, BRINGING LOCALIZED IFR VISIBILITY AND
FREQUENT LIGHTNING. THERE WILL ALSO BE SOME GUSTY ERRATIC WINDS.
THIS IS EXPECTED AT BTV AND PBG BETWEEN 6-7Z AND RUT BEFORE 9Z.
THESE STORMS EXIT BY AROUND DAYBREAK. VFR CONDITIONS ARE EXPECTED TO
PREVAIL THROUGH TONIGHT. WINDS WILL INCREASE INTO THE 15-25 KT RANGE
OUT OF THE NORTHWEST TODAY, BEFORE GENERALLY GOING LIGHT AND
VARIABLE TONIGHT. A FEW POCKETS OF LLWS WILL EXIST FOR THE REST OF
THE NIGHT, BEFORE GOING AWAY THIS MORNING.
