DISCUSSION
KEY MESSAGE 1...
THE PASSAGE OF AN UPPER-LEVEL TROUGH THIS AFTERNOON THROUGH THIS
EVENING, POTENTIALLY ALONG WITH ENHANCED LOW-LEVEL SUPPORT FOR
ASCENT THROUGH WEAK MOHAWK-HUDSON CONVERGENCE, WILL SUPPORT THE
CONTINUATION OF LIGHT, SCATTERED SNOW SHOWERS (OR SNOW/RAIN SHOWERS
WHERE TEMPERATURES ARE A BIT MORE MILD) ACROSS THE REGION. HOWEVER,
WARMER GROUND SURFACES SHOULD ENSURE LITTLE, IF ANY, ACCUMULATION
AND THEREFORE MITIGATE ANY THREAT OF SLIPPERY TRAVEL CONDITIONS FOR
THE EVENING COMMUTE. AMPLE CLOUD COVER THROUGHOUT THE REMAINDER OF
THE DAY WILL ALSO ENSURE TEMPERATURES REMAIN ON THE CHILLY SIDE,
PRIMARILY IN THE 30S.
HIGH PRESSURE BUILDS IN SWIFTLY BEHIND THE DEPARTING TROUGH TONIGHT,
BRINGING AN END TO ANY LINGERING SHOWERS AND HELPING TO SCATTER OUT
LASTING CLOUD COVERAGE. LARGELY DRY CONDITIONS WILL PERSIST THROUGH
AT LEAST WEDNESDAY MORNING AS THE SURFACE ANTICYCLONE AND AN
ASSOCIATED WEAK, UPPER-LEVEL RIDGE REMAIN IN PLACE. A WEAK SHORTWAVE
TROUGH WILL FLATTEN THE RIDGE A BIT TUESDAY NIGHT AND POTENTIALLY
BRING LIGHT SNOW SHOWERS TO THE HIGHEST ELEVATIONS OF THE
ADIRONDACKS, BUT AS THIS IS A FAIRLY WEAK SYSTEM WITH ALREADY
LIMITED MOISTURE, THE PROBABILITY OF PRECIPITATION ACTUALLY
REACHING THE GROUND IS VERY LOW.
THE DOMINATING ANTICYCLONE BEGINS TO DEPART TO THE EAST-
SOUTHEAST WEDNESDAY, GIVING WAY TO AN ADVANCING FRONTAL SYSTEM.
LIGHT, SCATTERED SHOWERS WILL BEGIN WEDNESDAY AFTERNOON AS A
SURFACE LOW SETTLES INTO THE EASTERN GREAT LAKES AND EXTENDS A
WARM FRONT EASTWARD. SHOWERS CONTINUE OVERNIGHT WEDNESDAY BEFORE
A BRIEF BREAK COMES THURSDAY MORNING. BUT BY THURSDAY
AFTERNOON, A STRONGER LOW WILL ENTER THE EASTERN GREAT LAKES
WITH A COLD FRONT IN ATTENDANCE. THIS SYSTEM LOOKS TO BRING
WIDESPREAD RAIN ACROSS EASTERN NEW YORK AND WESTERN NEW ENGLAND
THAT COULD POTENTIALLY BECOME MODERATE TO LOCALLY HEAVY AT TIMES
AS THE LOW TRACKS CLOSE BY. RAIN LOOKS TO BEGIN THURSDAY
AFTERNOON AND LAST THROUGH THURSDAY NIGHT. LATEST NBM
PROBABILITIES RANGE FROM ABOUT 40-60% FOR AT LEAST 0.25" THROUGH
FRIDAY MORNING AND THIS LUCKILY WILL NOT BE ENOUGH TO RAISE ANY
CONCERNS FOR HYDROLOGICAL ISSUES. IN FACT, THE LATEST NAEFS
HARDLY SHOWS ANY RIVER RESPONSE OVER THE NEXT SEVEN DAYS. BUT,
AS THIS IS OUR PRIMARY OPPORTUNITY FOR WIDESPREAD PRECIPITATION
OVER THE NEXT SEEN DAYS, WE WILL MONITOR CONDITIONS AND TRENDS
CLOSELY IN THE COMING DAYS TO ENSURE THAT DOESN'T CHANGE.
ONCE THE COLD FRONT DEPARTS FRIDAY, HIGH PRESSURE BUILDS BACK IN
ACROSS THE REGION TO GIVE US A DRY START TO THE WEEKEND. ANOTHER
WEAK SHORTWAVE MAY BRING SOME ADDITIONAL SCATTERED SHOWERS
SATURDAY NIGHT, BUT GENERALLY IT SHOULD BE A FAIRLY TRANQUIL
WEEKEND.
AVIATION /06Z TUESDAY THROUGH SATURDAY/
THROUGH 06Z WEDNESDAY...HIGH PRESSURE BUILDING IN FROM THE WEST
WILL RESULT IN CONTINUED VFR CONDITIONS, WITH ANY LINGERING
CLOUDS DISSIPATING PRIOR TO 12Z. MID LEVEL CLOUDS WILL INCREASE
THIS AFTERNOON AHEAD OF AN APPROACHING DISTURBANCE, BUT CIGS
WILL REMAIN AT OR ABOVE 10 KFT AGL WITH NO PRECIPITATION. WINDS
WILL BE NORTHWEST AROUND 10 KT OR LESS, BECOMING WEST-SOUTHWEST
THIS AFTERNOON.
