DISCUSSION
ISSUED AT 138 AM EDT FRI OCT 31 2025
CURRENTLY EARLY THIS MORNING, UPPER TROUGHING CONTINUES TO LIFT TO
OUR NORTHEAST WITH THE SYSTEM THAT RECENTLY IMPACTED THE AREA MOVING
INTO NEW ENGLAND. NORTHWESTERLY FLOW WILL REMAIN BUT WEAKEN TO 25
KTS OR LESS WITH SOME 850MB MOISTURE KEEPING CHANCES FOR A FEW
MORNING FLURRIES IN THE MOUNTAINS. OTHERWISE, BREEZY WINDS AND
GRADUAL CLEARING CAN BE EXPECTED AS HIGH PRESSURE EXPANDS FROM THE
SOUTHWEST. HEADING INTO SATURDAY, TROUGHING WILL DEEPEN ACROSS THE
REGION WITH HIGH PRESSURE KEEPING PLACES COOL AND DRY FOR MOST OF
THE DAY. HOWEVER, A WEAK FRONT WILL MOVE IN SATURDAY NIGHT WITH
MOISTURE SUFFICIENT FOR PRECIP CHANCES. THIS IS EXPECTED TO BE ALL
RAIN AS LOW-LEVEL TEMPERATURES WILL REMAIN WELL ABOVE FREEZING. BY
SUNDAY, A CLOSED LOW WILL BECOME CUT OFF AND INTERACT WITH A
DISTURBANCE IN THE GULF, SHIFTING MOISTURE AND RAIN CHANCES TO OUR
SOUTH AND EAST.
BY MONDAY, THE FLOW ALOFT WILL BECOME ZONAL AGAIN AS THE CLOSED LOW
CONTINUES MOVING FURTHER SOUTH AND EAST. SURFACE HIGH PRESSURE WILL
ARRIVE BACK IN THE AREA, PROMOTING DRY CONDITIONS AND COOL OVERNIGHT
LOWS DUE TO SUBSIDENCE. HEIGHT RISES WILL THEN LEAD TO A GRADUAL
WARMING TREND THROUGH THE WEEK WITH HIGH PRESSURE KEEPING THE REGION
DRY.
