KEY MESSAGE:
- A DRY "BACKDOOR" COLD FRONT ARRIVES FRIDAY NIGHT.
A SURFACE HIGH PRESSURE SYSTEM WILL LEAD TO CONTINUED CLEAR TO
MOSTLY CLEAR SKIES THIS AFTERNOON AND EVENING. THE COMBINATION OF
CONTINUED OFFSHORE FLOW, COLD AIR ADVECTION, AND MOSTLY CLEAR
SKIES TONIGHT WILL PROMOTE EFFICIENT RADIATIONAL COOLING,
RESULTING IN OVERNIGHT LOWS DROPPING TO THE MID TO UPPER 40S
ACROSS THE VICTORIA CROSSROADS AND NORTHERN PORTIONS OF THE BRUSH
COUNTRY. ELSEWHERE, TEMPERATURES WILL SETTLE INTO THE LOW- TO-MID
50S.
FRIDAY WILL FEATURE AFTERNOON HIGH TEMPERATURES COMPARABLE TO
TODAY. HOWEVER, A REINFORCING PUSH OF DRIER AIR WILL ARRIVE FRIDAY
NIGHT AS A DRY "BACKDOOR" COLD FRONT MOVES INTO THE REGION.
NORTHEASTERLY WINDS, AROUND 10-15 MPH, WILL DEVELOP BEHIND THE
FRONT AS SURFACE HIGH PRESSURE AGAIN BUILDS BACK INTO THE AREA
AGAIN. IN THE WAKE OF THIS FRONT, OVERNIGHT LOWS WILL BECOME
NOTABLY COOLER. THE VICTORIA CROSSROADS MAY EXPERIENCE LOWS IN THE
UPPER 30S, WHILE THE REMAINDER OF THE REGION IS EXPECTED TO SEE
LOWS IN THE 40S.
