AFTER LOOKING AT THE LATEST DATA, NO CHANGES WERE NEEDED DURING
THE MORNING FORECAST UPDATE. WE WILL REMAIN UNDER THE INFLUENCE OF
HIGH PRESSURE THAT WILL CONTINUE TO ENFORCE A COOLER AND DRIER
AIRMASS OVER THE AREA WITH MOSTLY CLEAR SKIES AND LIGHT EASTERLY
WINDS TODAY. THE PREVIOUS FORECAST REMAINS ON TRACK.
A DOME OF HIGH PRESSURE CURRENTLY SITS OVER QUEBEC, EXPECTED TO
SINK FURTHER SOUTH WITH TIME. MEANWHILE, WHAT WAS ONCE AMPLIFIED
RIDGING OVERHEAD, WILL BROADEN ACROSS MUCH OF THE COUNTRY. WE
WILL SIT UNDER THIS INFLUENCE OF BROADENED RIDGING AND SURFACE
HIGH PRESSURE THAT WILL EVENTUALLY CENTER OVER THE MID-ATLANTIC
REGION. A DEVELOPING TROUGH WILL DEEPEN AND MOVE EASTWARD,
COMPRESSING THE RIDGE AND POTENTIALLY CHANGE OUR WEATHER PATTERN
NEXT WEEK.
TODAY WILL BE NOTABLY COOLER THAN YESTERDAY, WITH VALLEY HIGHS
REMAINING IN THE LOWER 80S INSTEAD OF THE MID TO UPPER 80S. IT
WILL ALSO FEEL A BIT DRIER OUT TOO. TEMPERATURES WILL CONTINUE
THE "COOLER" TREND OR WHAT'S NORMAL FOR OCTOBER, AS WELL AS DRIER
AIR SETTLING IN FOR AT LEAST PART OF THE WEEKEND, BEFORE MOISTURE
RETURN. WITH THAT SAID, EXPECT QUIET AND CALM CONDITIONS WEATHER-
WISE THROUGH EARLY SUNDAY OR SO. SUNDAY INTO MONDAY TIME FRAME, A
GULF COAST FRONTAL BOUNDARY MAY TRY TO SEND MOISTURE NORTHWARD
TOWARDS OUR AREA, RETURNING THE CHANCE FOR PRECIPITATION. THE
AFOREMENTIONED TROUGH WILL MARCH ACROSS THE COUNTRY WITH A
DEVELOPING COLD FRONT THAT MAY IMPACT THE AREA AROUND THE END OF
THE FORECAST PERIOD OR THE MIDDLE OF NEXT WEEK.
