AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
242 PM EDT SAT JUN 18 2011

...HOT AND SMOKEY FOR THE JACKSONVILLE AREA THIS FATHERS DAY...

.SHORT TERM...
TONIGHT SOME CONVECTION BEGINNING TO DEVELOP IN THE SYNOPTIC FLOW
OVER THE SOUTHERN FORECAST AREA AND EXPECT ISOLATED TO WIDELY
SCATTERED CONVECTION TO BREAK OUT ACROSS MOST OF THE FORECAST AREA
LATER THIS EVENING. SMOKE FROM THE FIRES WILL FOLLOW A TRAJECTORY
TOWARD NORTHEAST FLORIDA AND EXPECT THAT TO CONTINUE THROUGH
WEDNESDAY. IT IS GOING TO BECOME SMOKEY AGAIN IN THE JACKSONVILLE
METRO AREA AND LIKELY THROUGH MID WEEK.

HIGH PRESSURE IS GOING BUILD IN WEST OF THE AREA BRINGING A DRIER
AND HOTTER PATTERN TO THE AREA BEGINNING TOMORROW. WHILE THE CAP
WILL BE STRONG I HAVE CONFIDENCE THAT NEAR 100 DEGREE TEMPERATURES
OVER THE INTERIOR WILL GENERATE ENOUGH LIFT TO ALLOW ISOLATED
CELLS TO BLOW THROUGH THE CAP AND THUS HAVE 15-20 PERCENT
AFTERNOON AND EVENING POPS THROUGH WEDNESDAY. KEPT THE HIGHER
NUMBERS TOWARD THE EASTERN PORTION OF THE FORECAST AREA DUE TO THE
SYNOPTIC FLOW. TEMPERATURES WILL BE ABOUT 5 OR SO DEGREES ABOVE
CLIMO AND HEAT INDEX VALUES IN THE LOW TO MID CENTURY RANGE
THROUGH MID WEEK.

.LONG TERM...
A SIGNIFICANT LONG WAVE TROUGH BEGINS TO DROP INTO THE LOWER
MISSISSIPPI RIVER VALLEY ON THURSDAY AND FRIDAY WITH THE NEXT
CHANCE FOR A DECENT SYNOPTIC LEVEL RAINFALL BEING ON THURSDAY
NIGHT INTO FRIDAY. DO NOT GET HOPES UP TOO HIGH YET AS THE TEN
DAY PRECIPITATION FORECAST THROUGH TUESDAY JUNE 28TH HAS ONLY 1.5
TO 2 INCHES OF GENERAL RAINFALL ACROSS THE FORECAST AREA. GFS IS
FORECASTING A LARGE AREA OF HEAVY RAINFALL OVER THE CENTRAL GULF
OF MEXICO AND MAYBE WE WILL GET LUCKY AND HAVE SOME OF THAT SHIFT
EAST.

.AVIATION...SMOKE WILL CONTINUE TO BE A PROBLEM AND EXPECTED TO
POUR BACK INTO JAX METRO AREA AGAIN TONIGHT AND SUNDAY. WILL CARRY
FU ALONG WITH VSBY WITH MVFR AGAIN LATE TONGT. WILL KEEP MVFR AT
SSI NEXT 24 HRS. HAVE INCLUDED TEMPO FOR TSRA THIS AFTN.

&&

.MARINE...NO HEADLINES EXPECTED THROUGH SUNDAY. SOUTHWEST TO
SOUTHERLY NOCTURNAL SURGES ARE EXPECTED NEXT SEVERAL NIGHTS WITH
BRIEF SCEC NEAR THE GULF STREAM.

&&

.FIRE WEATHER...ALTHOUGH RH VALUES ARE FORECAST TO REMAIN ABOVE 35
PCT INTO THE MIDDLE OF NEXT WEEK...RAIN CHANCES ARE LIMITED AND AN
ELEVATED FIRE DANGER WILL PERSIST. DO NOT ANTICIPATE ANY RED FLAGS
UNLESS RH'S DROP INTO CRITICAL RANGE ALONG THE TRAIL RIDGE NEXT WEEK.
