DISCUSSION
KEY MESSAGE 1...
A WEAK COLD FRONT CONTINUES TO APPROACH FROM WESTERN AND
NORTHERN NY WITH SOME CLOUDS OVER THE NORTH COUNTRY AND
ADIRONDACKS THIS AFTERNOON. A SFC PRESSURE GRADIENT BETWEEN THE
COLD FRONT AND THE MID-LEVEL SHORT-WAVE TO THE WEST/NORTHWEST
AND SUBTROPICAL STORM JOSEPHINE MOVING NORTHEAST INTO THE
ATLANTIC HAS ALLOWED FOR NORTH/NORTHWEST WINDS 5-15 MPH WITH
SOME GUSTS 20-25 MPH ESPECIALLY SOUTH AND EAST OF THE CAPITAL
REGION. THE WINDS WILL GRADUALLY DIMINISH TONIGHT, AS THE SFC
COLD FRONT WASHES OUT. LIGHT NORTH/NORTHWEST WINDS MAY PERSIST
AFTER MIDNIGHT FROM THE CAPITAL REGION SOUTH AND EAST, AS THE
SFC HIGH BUILDS IN FROM SOUTHEAST ONTARIO AND SOUTHERN QUEBEC.
WITH THE WEAK LOW-LEVEL COLD ADVECTION LOWS FALL BACK INTO THE
30S WITH SOME UPPER 20S OVER THE HIGHER TERRAIN.
A STRONG SFC ANTICYCLONE BUILDS IN OVER EASTERN NY AND WESTERN
NEW ENGLAND TOMORROW, AND LASTS THROUGH THE WEEKEND. THE STRONG
SUBSIDENCE FROM THE RIDGE WILL YIELD MOSTLY SUNNY CONDITIONS.
PWATS WILL RUN 1-2 STDEVS BELOW NORMAL IN THE DRY AIR MASS.
SHALLOW MIXING HEIGHTS AND WEAK COLD ADVECTION WILL YIELD
SLIGHTLY BELOW NORMAL TEMPS WITH HIGHS IN THE UPPER 40S TO MID
AND SPOTTY UPPER 50S FOR FRI. THE SFC HIGH OVER SOUTHERN
QUEBEC, NY AND NEW ENGLAND WILL YIELD IDEAL RADIATIONAL COOLING
CONDITIONS WITH MOSTLY CLEAR SKIES, LIGHT TO CALM WINDS WITH
LOWS IN THE 20S WITH A FEW UPPER TEENS OVER THE SOUTHERN DACKS
FRI NIGHT. WE WENT BELOW THE NBM GUIDANCE FOR LOWS GOING CLOSER
TO THE MAV/MET GUIDANCE. HIGH PRESSURE REMAINS DOMINATE FOR THE
WEEKEND WITH TEMPS MODIFYING TO SEASONAL TO SLIGHTLY ABOVE
NORMAL TEMPS WITH LIGHT WINDS. IDEAL RADIATIONAL COOLING IS
EXPECTED AGAIN SAT NIGHT WITH CHILLY TEMPS. THE MID AND UPPER
LEVEL HEIGHTS BEGIN TO FALL SUN NIGHT INTO MON AS THE THE FLOW
ALOFT BECOMES MORE ZONAL WHICH WILL ALLOW TEMPS TO RUN NEAR TO
SLIGHT ABOVE NORMAL. THE NEXT CHANCE OF RAINFALL LOOKS LIKE
POTENTIALLY WED INTO THU WITH A SHORT-WAVE AND A WARM FRONT, BUT
PRECIPITATION LOOKS LIGHT IN THE MEDIUM RANGE/ENSEMBLE/NBM
GUIDANCE.
