HIGHER HUMIDITY BY LATE WEEK.
DISCUSSION
KEY MESSAGE 1 DESCRIPTION...
SURFACE HIGH PRESSURE WILL BUILD TO OUR SOUTHWEST TODAY,
ALLOWING FOR MAINLY SUNNY SKIES WITH HIGH TEMPERATURES INTO THE
UPPER 70S/LOWER 80S ACROSS THE NORTH WITH MIDDLE TO UPPER 80S
SOUTH OF THE MOUNTAINS. DAYTIME MIXING WILL ALLOW FOR
COMFORTABLE HUMIDITY VALUES WITH DEW POINTS MAINLY INTO THE 50S.
IT WILL BE A BIT BREEZY AS WELL WITH WESTERLY WIND GUSTS UP TO
AROUND 25 MPH AT TIMES, ESPECIALLY THROUGH THE FIRST HALF OF THE
DAY.
CLEAR TO PARTLY CLOUDY SKIES TONIGHT COMBINED WITH LIGHT WINDS
WILL ALLOW TEMPERATURES TO COOL TO AROUND 50 DEGREES ACROSS SOME
INTERIOR VALLEYS WITH UPPER 50S TO LOWER 60S ELSEWHERE.
THE WARMING TREND WILL CONTINUE ON WEDNESDAY THROUGH THE
REMAINDER OF THE WEEK AS A BERMUDA HIGH ALLOWS FOR SUB-TROPICAL
AIR TO BE TRANSPORTED NORTHWARD AS SOUTH-SOUTHWESTERLY FLOW
PREVAILS AT THE SURFACE. THIS WILL ALLOW FOR TYPICAL AUGUST
WEATHER WITH HIGH TEMPERATURES EACH DAY INTO THE 80S TO NEAR 90
DEGREES AND ELEVATED DEW POINTS INTO THE 60S TO NEAR 70 DEGREES
AT TIMES. THE PEAK OF THE HEAT AND HUMIDITY CURRENTLY LOOKS TO
BE ON FRIDAY WHEN AFTERNOON HEAT INDICES MAY APPROACH THE
MIDDLE 90S ACROSS SOME INTERIOR LOCATIONS SOUTH OF THE
MOUNTAINS.
AS IS OFTEN THE CASE IN THE SUMMER, WE WILL NEED TO WATCH FOR
DIURNALLY DRIVEN SHOWERS AND THUNDERSTORMS MOST DAYS. WHILE NO
PARTICULAR DAY CURRENTLY LOOKS OVERLY SUPPORTIVE FOR SEVERE
STORMS, DEPENDING ON THE TIMING OF A FEW WEAK WAVES OF ENERGY,
A FEW STRONG TO SEVERE STORMS CANNOT BE RULED OUT, ESPECIALLY
TOWARDS LATE WEEK OR THIS UPCOMING WEEKEND.
AVIATION /12Z TUESDAY THROUGH SATURDAY/
THROUGH TUESDAY NIGHT: VFR CONDITIONS EXPECTED, ALTHOUGH SOME
PATCHY FG IS POSSIBLE BOTH TONIGHT AND TUESDAY NIGHT. THE
GREATEST POTENTIAL FOR FG IS AT LEB AND HIE. W WINDS WILL
PREVAIL WITH GUSTS THROUGH TUESDAY UP TO 25 KTS. WINDS WILL
BECOME LIGHT AND VARIABLE TUESDAY NIGHT. NO LLWS IS ANTICIPATED
THROUGH THE PERIOD.
OUTLOOK:
WEDNESDAY-SATURDAY: MAINLY VFR CONDITIONS EXPECTED WITH S-SW
PREVAILING. THE EXCEPTION WILL BE WITHIN AN POSSIBLE SHRA/TSRA,
WITH THE GREATEST POTENTIAL FOR THIS DURING THE AFTERNOON AND
EARLY EVENING HOURS, ESPECIALLY TOWARDS LATE WEEK. NIGHTTIME AND
EARLY MORNING FG ALSO CANNOT BE RULED OUT, ESPECIALLY ACROSS
INTERIOR VALLEY AND COASTAL TAF SITES.
MARINE
SEAS WILL REMAIN ELEVATED AT 4-6 FT THROUGH THIS AFTERNOON WITH
THE SCA REMAINING IN EFFECT. BERMUDA HIGH PRESSURE WILL THEN BRING
LIGHT WINDS AND FAIR SEAS MID TO LATE WEEK WITH S-SW WINDS OF
GENERALLY 10-15 KTS AND SEAS OF 2-4 FT.
