DISCUSSION
AS OF 243 PM EDT SATURDAY...
KEY MESSAGE 1: DESPITE A FEW SHOWERS TODAY AND TOMORROW
DUE TO A COUPLE OF PASSING TROUGHS, TEMPERATURES WILL BE
TRENDING MARKEDLY WARMER THROUGH MID WEEK. SOUTHERLY FLOW
DEVELOPS SUNDAY KICKING OFF WARM AIR ADVECTION IN EARNEST
BRINGING SURFACE TEMPERATURES BACK TO AROUND SEASONAL AVERAGES
GENERALLY IN THE 40S BEFORE INCREASING INTO THE LOW/MID 50S
THROUGH WEDNESDAY FOR MOST LOCATIONS. OVERNIGHT LOWS WILL FOLLOW
A SIMILAR WARMING TREND WITH TEMPERATURES RUNNING BELOW SEASONAL
AVERAGES TONIGHT RANGING FROM THE TEENS TO MID 20S, ABOVE
FREEZING BY MONDAY NIGHT.
KEY MESSAGE 2: THE NEXT SYSTEM REMAINS ON TRACK TO MOVE INTO THE
REGION TUESDAY WITH MOST MODEL GUIDANCE FAVORING THE QUASI-
STATIONARY BOUNDARY ALONG THE CANADIAN BORDER INTO SOUTHERN
CANADA. THERE IS STILL A LITTLE UNCERTAINTY ABOUT WHERE THIS
BOUNDARY WILL BE INITIALLY, BUT TRENDS SEEM TO BE POINTING TO
THE MORE NORTHERLY POSITIONING. AS SUCH, TEMPERATURES WILL
CONTINUE TO WARM AND FAVOR RAIN AT ONSET RATHER THAN A MIX OF
PRECIP OR SNOW. WILL CONTINUE TO MONITOR SINCE COLDER SOLUTIONS
WOULD POINT TO SOME IMPACTS. TRAJECTORY OF THE SYSTEM AND
ACCOMPANYING DYNAMICS CURRENTLY SUPPORT PWATS CLIMBING TO
AROUND 1" WITH SLOW/TRAINING MOTION VECTORS. THIS COULD MEAN
SOME DECENT RAIN TOTALS AS ENERGY TRACKS WEST TO EAST ALONG THE
BOUNDARY RATHER THAN HAVING A SHARP NORTHWEST-SOUTHEAST PUSH ON
TUESDAY. WITH THE REGION IN THE WARM SECTOR AHEAD OF THE COLD
FRONT, SOME THUNDERSTORM POTENTIAL EXISTS TUESDAY AFTERNOON
MAINLY IN NORTHERN NEW YORK - TIMING WILL NEED SOME REFINEMENT
GOING FORWARD, BUT A FEW CELLS COULD TRACK INTO WESTERN VERMONT
BY THE EVENING. MODELS POINT TO AN INCREASE IN THERMAL GRADIENT
OVERNIGHT WITH JET ENERGY PUSHING THE FRONT THROUGH MORE RAPIDLY
IN THAT TIME PERIOD. AS TEMPERATURES FALL, A TRANSITION TO SOME
SNOW SHOWERS SEEMS PROBABLE GIVEN LATEST GUIDANCE. QPF ON THE
BACK END WOULD BE LOWER THOUGH, SO ONLY A DUSTING OF SNOW IS
FAVORED AT THIS TIME. WINDS WILL BE GUSTY ALONG THE FRONT WITH
POTENTIAL FOR GUSTS TO 35 MPH AS FLOW TRANSITIONS MORE
NORTHWESTERLY.
KEY MESSAGE 3: ANOTHER STORM SYSTEM MAKES A RUN AT THE REGION FOR
FRIDAY, BUT IT CURRENTLY LOOKS TO TAKE A MORE SOUTHERLY TRACK.
CANADIAN HIGH PRESSURE WILL BE ESTABLISHED ON THURSDAY AND IT WILL
PROVIDE A COLD ANTECEDENT AIRMASS FOR THIS LOW PRESSURE TO RUN INTO.
WITH THE CURRENT FAVORED STORM TRACK, THE PRECIPITATION LOOKS TO
BEGIN AS SNOW AND GRADUALLY TRANSITION TO MIXED PRECIPITATION AND
RAIN, BUT BEING ALMOST A WEEK OUT, THERE IS PLENTY OF TIME FOR A
SIGNIFICANT CHANGE IN THE STORM TRACK AND THEREFORE PRECIPITATION
TYPES. COMBINED GEFS/EPS/CAN ENSEMBLE PROBABILITIES OF 1 INCH OR
MORE OF SNOW GENERALLY RANGE BETWEEN 35-55 PERCENT, 3 ARE BETWEEN 15-
35 PERCENT AND 6 ARE BETWEEN 5-15 PERCENT. PROBABILITIES OF 0.1 INCH
OR MORE OF FREEZING RAIN ARE BETWEEN 10-30 PERCENT FOR THE FAVORED
LOCATIONS EAST OF THE GREENS AND IN SOUTHERN ESSEX COUNTY NY.
AVIATION /00Z SUNDAY THROUGH THURSDAY/
THROUGH 00Z MONDAY...VFR CONDITIONS CURRENTLY PREVAIL ACROSS THE
REGION, AND WILL GENERALLY CONTINUE THROUGHOUT THE FORECAST
PERIOD. A FEW SCATTERED SNOW SHOWERS PERSIST ACROSS THE REGION,
AND THESE SHOWERS HAVE BROUGHT BRIEF PERIODS OF REDUCED FLIGHT
CONDITIONS TO TERMINALS, PARTICULARLY AT KSLK AND KMPV. SHOWER
ACTIVITY SHOULD CONTINUE TO WANE OVER THE NEXT FEW HOURS. WINDS
CONTINUE TO BE NORTHWESTERLY TO WESTERLY THIS EVENING, TRENDING
MORE LIGHT AND VARIABLE OVERNIGHT. WINDS WILL SHIFT TO BECOME
MORE SOUTHERLY DURING THE DAY TOMORROW, WITH SOME GUSTS OF 15 TO
20 KNOTS POSSIBLE DURING THE AFTERNOON.
