FORECAST IS BASED ON IGNITION TIME OF 1030 EDT ON JULY 02.
IF CONDITIONS BECOME UNREPRESENTATIVE...CONTACT THE NATIONAL WEATHER
SERVICE.
DISCUSSION
AN UPPER LEVEL TROUGH WILL SLIDE ACROSS THE REGION TODAY...AND
COULD SPARK OFF AN ISOLATED SHOWER OR THUNDERSTORM. MEANWHILE...
A WEAK SURFACE MOISTURE BOUNDARY WILL ALSO SLIDE EAST...AND COULD
ACT AS A FOCUS MECHANISM FOR CONVECTION. BOTTOM LINE...WHILE THERE
COULD BE A POP UP SHOWER OR THUNDERSTORM AT ANY TIME TODAY...THERE
WILL BE A BETTER CHANCE FROM LATE MORNING INTO THE AFTERNOON.
HOWEVER...WE ARE STILL TALKING ABOUT A LOW PROBABILITY EVENT.
DO NOT EXPECT MUCH OF WIND SHIFT WITH THE DEVELOPMENT OF THE SEA
BREEZE TODAY...AS THE LARGER SCALE FLOW IS ALREADY OUT OF THE
SOUTHWEST. PERHAPS ABOUT A 30 DEGREE DIRECTION SHIFT TO MORE OF
A SOUTHERLY COMPONENT ALONG WITH AN UP TO 5 MPH BUMP UP IN
MAGNITUDE BETWEEN NOON AND 2PM.
TOWARD EVENING...THE THREAT OF RAIN WILL CEASE. ALSO EXPECT WINDS
TO REVERT TO THE LIGHTER SOUTHWEST FLOW...WITH A SLIGHT DROP IN
DEW POINT TEMPERATURES FOR TONIGHT.
