SYNOPSIS

PRESSURE THEN PASSES NOT TOO FAR TO OUR SOUTH TONIGHT INTO SATURDAY
MORNING. HIGH PRESSURE THEN BUILDS BACK SATURDAY AFTERNOON AND WILL
REMAIN IN CONTROL THROUGH EARLY NEXT WEEK. THE HIGH MOVES OFFSHORE
ON TUESDAY FOLLOWED BY THE NEXT FRONTAL SYSTEM IMPACTING THE AREA
LATE TUESDAY INTO WEDNESDAY. HIGH PRESSURE SHOULD BUILD TOWARDS THE

HIGH PRESSURE WILL BE MOVING FARTHER OUT TO SEA TODAY. MOISTURE
ADVECTION FROM THE WEST LEAVES US WITH A MOSTLY CLOUDY DAY, BUT
REMAINING DRY. HIGH TEMPERATURES TODAY WILL BE MILDER THAN THOSE OF
YESTERDAY IN SPITE OF THE CLOUD COVER AND NEAR NORMAL IN THE RANGE
OF 50-55 DEGREES.
SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/
VARIOUS MODELS ARE NOW IN BETTER AGREEMENT COMPARED TO 24 HOURS AGO
REGARDING THE NORTHERN EXTENT OF THE PRECIP SHIELD ASSOCIATED WITH
WEAK LOW PRESSURE PASSING TO OUR SOUTH TONIGHT INTO SATURDAY
MORNING. ALTHOUGH THE LOW ITSELF IS WEAK, UPPER DIVERGENCE COURTESY
OF FAVORABLE POSITIONING OF A JET STREAK COUPLET SHOULD HELP BRING
THE LIKELIHOOD OF RAINFALL TO ROUGHLY THE SOUTHERN HALF OF THE
FORECAST AREA. NBM 6-HOUR POPS FOR LATE TONIGHT MATCHES THIS
THINKING. GREATEST CHANCES OF RAIN OVERALL WILL BE AFTER MIDNIGHT
TONIGHT UNTIL MID-MORNING SATURDAY. NO HYDROLOGIC IMPACTS EXPECTED
AS RAIN AMOUNTS LIKELY REMAIN BELOW A QUARTER OF AN INCH. HIGH
PRESSURE THEN BUILDS BACK IN FOR REST OF SATURDAY WITH CLEARING AND
DRY CONDITIONS. HIGHS FOR SATURDAY NEAR NORMAL AGAIN AT 50-55.
THE HIGH PRESSURE RIDGE AXIS SHIFTS INTO THE REGION DURING SUNDAY
WITH A CONTINUATION OF FAIR WEATHER. HIGH TEMPERATURES A LITTLE
COOLER THIS TIME.
LONG TERM /MONDAY THROUGH THURSDAY/
KEY POINTS:
* RAIN IS FORECAST LATE TUESDAY INTO TUESDAY NIGHT. THE CHANCE OF
RAIN CONTINUES ON WEDNESDAY, BUT CONFIDENCE IS LOWER.
* SEASONABLY COOL AND DRY CONDITIONS ON MONDAY, BECOMING MILDER FOR
TUESDAY AND WEDNESDAY.
* THE POTENTIAL REMAINS FOR A SEASONABLY COOL AND DRY THANKSGIVING.
NBM WAS FOLLOWED WITH NO SIGNIFICANT CHANGES. REGARDING THE RAIN
CHANCES FROM TUESDAY THROUGH THANKSGIVING, HIGHEST CHANCES STILL
APPEAR TO BE DURING TUESDAY NIGHT WITH HYDROLOGIC IMPACTS UNLIKELY.
RAIN CHANCES CONTINUE INTO WEDNESDAY, BUT AT LEAST THERE'S A LITTLE
MORE CONFIDENCE THAT CHANCES ARE NO MORE THAN 50%. THEN FOR
THANKSGIVING DAY, DETERMINISTIC AND ENSEMBLES FOR THE MOST PART
FAVOR A MORE PROGRESSIVE MOTION WITH THE MID-WEEK STORM SYSTEM,
LEAVING US WITH A GOOD CHANCE OF DRY CONDITIONS THROUGH THE DAY.
