DISCUSSION
KEY MESSAGE 1: DRY WEATHER CONTINUES THE REMAINDER OF THIS WEEK
AND INTO THE WEEKEND WITH TEMPERATURES NEAR TO JUST BELOW
NORMAL.
ANOTHER FAIRLY RINSE AND REPEAT FORECAST IS EXPECTED OVER THE
COMING 5 DAYS OR SO. AFTER A CHILLY MORNING WITH TEMPERATURES IN
THE LOW TO MID 40S, AFTERNOON TEMPERATURES TODAY ARE EXPECTED
TO TOP OUT NEAR NORMAL VALUES, IN THE MID TO UPPER 70S. THIS
COMES AS HIGH PRESSURE LINGERS IN THE REGION WITH A VERY DRY
AIRMASS (PWAT'S UNDER 0.50"). HEADING INTO THE LATE WEEK, A DEEP
TROUGH CURRENTLY OFF THE SOUTHERN CA COAST, WILL SLOWLY WORK
EASTWARD INTO THE FOUR CORNERS REGION, FURTHER AMPLIFYING THE
CENTRAL CONUS RIDGE AND TROUGHING OVER THE EASTERN US. WHILE
THIS UPPER LEVEL PATTERN SHOULD NOT BRING ANY SIGNIFICANT
CHANGES TO THE PATTERN WE ARE CURRENTLY IN, HIGH TEMPERATURES
FRIDAY AND SATURDAY CONTINUE TO TREND COOLER, TOWARD THE UPPER
60S TO LOW 70S FRIDAY AND THE MID TO UPPER 60S SATURDAY. LATE
THIS WEEKEND INTO EARLY NEXT WEEK, TEMPERATURES LIKELY NEAR
NORMAL VALUES AGAIN AS GLOBAL MODELS SHOW THE RIDGE FINALLY
BUILDING OVERHEAD WITH SURFACE HIGH PRESSURE WORKING INTO THE
CAROLINAS. AS DISCUSSED THE PAST FEW DAYS, THE CHANCE FOR
MEANINGFUL RAINFALL REMAINS VERY LOW INTO EARLY NEXT WEEK WITH
MINIMAL MOISTURE ADVECTION INTO THE SOUTHEAST.
AVIATION /12Z WEDNESDAY THROUGH SUNDAY/
VFR CONDITIONS LIKELY THROUGH THE NEXT 24 HOURS.
LIGHT NORTHERLY FLOW WILL REMAIN IN PLACE WITH STRONG HIGH
PRESSURE STILL OVER THE REGION. EXPECT CLEAR OR MOSTLY CLEAR
SKIES. NORTH OR NNE WINDS AROUND 5 KTS WILL BECOME LIGHT AND
VARIABLE OR CALM AROUND SUNSET AND REMAIN THAT WAY OVERNIGHT.
SHALLOW FOG OFF THE RIVER WILL BE POSSIBLE AT AGS EARLY THURSDAY
MORNING BUT CONFIDENCE IS LOW AT THIS POINT.
EXTENDED AVIATION OUTLOOK...MOISTURE CREEPS BACK INTO THE AREA
THIS WEEKEND. SOME PATCHY FOG WILL BE POSSIBLE LATE IN THE
EXTENDED.
