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...
