DISCUSSION
KEY MESSAGE 1
HIGH PRESSURE BUILDS NORTH OF THE AREA TODAY AS A LOW PRESSURE
SYSTEM DEVELOPS WELL WEST OF THE AREA.
A DECAYING COLD FRONT PUSHES THROUGH THE AREA EARLY MORNING
ALLOWING A S/W FLOW TO SHIFT MORE NW/N. HIGH PRESSURE NORTH OF
THE AREA SHIFTS EAST THROUGH THE DAY ALLOWING FLOW TO SHIFT MORE
NE, REINFORCING A MORE MARINE AIRMASS BACK OVER THE AREA LATE
TODAY. THIS WILL PREVENT HIGH TEMPERATURES FROM CLIMBING TOO
MUCH TODAY, GENERALLY PEAKING IN THE UPPER 50S TO LOW 60S ALONG
THE COAST WITH PERHAPS MIDDLE TO UPPER 60S FOR WESTERN AREAS.
THE NE FLOW ALSO BRINGS THE CHANCE OF LOW STRATUS AND FOG
DEVELOPMENT TONIGHT AS A STRONGLY INVERTED LOW LEVEL WILL TRAP
MOISTURE IN THE BL.
THE WEAK FRONT ONCE AGAIN STALLS NEAR OR JUST SOUTH OF THE AREA
TONIGHT. AS THE FRONTAL SYSTEM FROM THE WEST APPROACHES INTO
SUNDAY, THE FRONT MAY MOVE BACK NORTH AS A WEAK WARM FRONT,
ALLOWING FOR THE DEVELOPMENT OF SCATTERED SHOWERS OVER THE AREA
LATE TONIGHT. THE ASSOCIATED COLD FRONT WILL GRADUALLY PUSH
THROUGH ON SUNDAY, BRINGING A PERIOD OF RAINFALL TO THE ENTIRE
AREA AS THE FRONT PUSHES THROUGH. INSTABILITY WILL BE LOW BUT A
FEW RUMBLES OF THUNDER CAN'T BE RULED OUT ALONG WITH POCKETS OF
MODERATE TO POSSIBLY BRIEFLY HEAVY RAINFALL. TOTAL RAINFALL
ACCUMULATIONS OF 0.25-0.5 INCHES ARE POSSIBLE ACROSS THE ENTIRE
AREA.
FOLLOWING THE FRONTAL PASSAGE, CONDITIONS LOOK TO DRY OUT AS
HIGH PRESSURE NOSES IN FROM THE SOUTH SUNDAY NIGHT INTO MONDAY.
KEY MESSAGE 2
WEAK FRONT MOVES THROUGH MONDAY NIGHT INTO TUESDAY, WITH
CONDITIONS TURNING COOLER AND QUIETER BEHIND IT THROUGH MID
NEXT WEEK. A FEW SCATTERED SHOWERS, PERHAPS EVEN MIXING WITH WET
SNOW ACROSS THE INTERIOR, ARE POSSIBLE WITH THE FROPA EARLY TUE
AM, BUT COVERAGE APPEARS SPOTTY AND QPF IS LIGHT.
SURFACE HIGH PRESSURE THEN BUILDS OVER THE REGION IN ITS WAKE
WITH DRY CONDITIONS EXPECTED. THE HIGH USHERS IN A COOL
CANADIAN AIR MASS, WITH DAYTIME TEMPERATURES LIKELY IN THE 40S
AND 50S, OR ABOUT 5 TO 10 DEGREES BELOW NORMAL FOR EARLY APRIL.
THESE COOLER CONDITIONS BECOME MORE SEASONABLE BY THURSDAY WITH
PERHAPS A WARMING TREND INTO NEXT WEEKEND.
