SPOT FORECAST FOR IRVINE RX...MARYLAND DNR FOREST SERVICE
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
1039 AM EDT SUN MAR 29 2026
FORECAST IS BASED ON IGNITION TIME OF 0800 EDT ON MARCH 30.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.
PLEASE CONTACT OUR OFFICE IF YOU HAVE QUESTIONS
OR CONCERNS WITH THIS FORECAST.
DISCUSSION
MONDAY AND TUESDAY WILL BE SIMILAR IN THAT THE AREA WILL BE
POSITIONED BETWEEN HIGH PRESSURE OFF THE COAST AND A FRONTAL
ZONE OVER THE GREAT LAKES. THIS WILL RESULT IN GUSTY SOUTH
TO SOUTHWEST WINDS EACH DAY, PERHAPS A LITTLE STRONGER MONDAY
COMPARED TO TUESDAY. THE FORECAST IS STILL A BIT IN FLUX, AND
THE TABLES BELOW ARE BASED ON SATURDAY EVENING'S MODEL DATA.
HOWEVER, MORE RECENT DATA IS TRENDING TOWARD HIGHER CHANCES
FOR SCATTERED RAIN SHOWERS OR SPRINKLES ON MONDAY ALONG WITH
MORE CLOUDS. HOWEVER, IF RAIN WERE TO OCCUR, AMOUNTS WOULD
LIKELY BE LESS THAN ONE TENTH OF AN INCH. WHILE A STRAY SHOWER
CAN'T BE RULED OUT TUESDAY, I THINK BASED ON THE CURRENT
DATA THAT IT WILL MORE LIKELY REMAIN DRY. THE OTHER DECISION
POINT IS THAT TEMPERATURES AND DEW POINTS WILL CONTINUE TO
TREND UPWARD. HOWEVER, RELATIVE HUMIDITY WILL LIKELY BE A BIT
LOWER ON TUESDAY AS AIR TEMPERATURES RISE TO NEAR 80F.
I MODIFIED THE START TIME OF THE FORECAST TO 8 AM MONDAY SO
THE TABLES BELOW REFLECT BOTH MONDAY AND TUESDAY.
