Area forecast discussion, Jul 30, 2:00 PM EDT, 1 hour 50 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 200 PM EDT WED JUL 30 2008 .DISCUSSION... THE EAST COAST SEA BREEZE WAS PUSHING FURTHER INLAND OVER THE SOUTHERN AREAS...THEN OVER THE NORTHERN AREAS EARLY THIS AFTERNOON. THE SOUTHERN PORTION OF THE EAST COAST SEA BREEZE SHOULD CONTINUE TO PUSH INLAND WHILE THE NORTHERN PORTION REMAINS CLOSER TO THE COASTLINE...DUE TO THE SOUTH TO SOUTHWEST STEERING FLOW. AT THE SAME TIME...THE WEST COAST SEA BREEZE WILL ALSO CONTINUE TO PUSH ACROSS THE CWA TOWARDS THE EAST COAST AREAS THROUGH THE AFTERNOON HOURS. SHOWERS AND THUNDERSTORMS WILL ALSO CONTINUE TO DEVELOP ALONG BOTH SEA BREEZES AND MOVE TO THE NORTH TO NORTHEAST DIRECTION THIS AFTERNOON INTO EARLY THIS EVENING. THIS WILL FOCUS MOST OF THE ACTIVITY OVER THE NORTHERN AND NORTHEAST AREAS OF THE CWA THIS AFTERNOON INTO THIS EVENING. SO WILL HAVE THE HIGHEST POPS OVER THE NORTHERN AREAS TAPERING DOWN AS YOU HEAD SOUTH. THE RIDGE OF HIGH PRESSURE IN THE LOWER LEVELS OF THE ATMOSPHERE WILL REMAIN OVER THE SOUTHERN PORTIONS OF SOUTH FLORIDA THROUGH FRIDAY. THIS WILL KEEP THE SOUTH TO SOUTHWEST WINDS OVER THE CWA THROUGH FRIDAY. AT THE SAME TIME...A TROPICAL WAVE EAST OF THE WINDWARD ISLANDS WILL ALSO MOVE WEST TO NORTHWEST TOWARDS SOUTH FLORIDA. DRIER AIR AHEAD OF THE TROPICAL WAVE WILL MOVE INTO THE CWA FOR THURSDAY AND FRIDAY. SO HAVE LOWER THE POPS DOWN TO ISOLATED TO LOW END CHANCE CAT FOR THURSDAY INTO FRIDAY WITH THE HIGHEST POPS OVER THE NORTHERN AREAS. THE SURFACE RIDGE OF HIGH PRESSURE WILL THEN MOVE NORTH INTO CENTRAL FLORIDA LATE THIS WEEKEND...AS THE NORTHERN PORTION OF THE TROPICAL WAVE PASSES THROUGH SOUTH FLORIDA. THIS WILL ALLOW FOR THE WINDS TO BECOME SOUTH TO SOUTHEAST OVER THE AREA...AND INCREASE THE MOISTURE OVER THE AREA. SO HAVE LEFT SCATTERED POPS OVER THE CWA LATE THIS WEEKEND. .EXTENDED FORECAST... THE RIDGE OF HIGH PRESSURE WILL REMAIN OVER CENTRAL FLORIDA FOR EARLY TO MIDDLE OF NEXT WEEK. THIS WILL KEEP THE WINDS FROM THE SOUTHEAST DIRECTION OVER THE CWA FOR THE EARLY TO MIDDLE OF NEXT WEEK. SO THE HIGHEST POPS WILL BE OVER THE WESTERN AREAS OF THE CWA FOR THE EARLY TO MIDDLE OF NEXT WEEK...BUT THE EAST COAST CAN STILL SEE ISOLATED TO SCATTERED COVERAGE. && .AVIATION... CONVECTIVE SHOWERS AND THUNDERSTORMS ARE FIRING ALONG THE SEA BREEZE CONVERGENCE IN DADE AND BROWARD, BUT SEA BREEZE HAVING A HARD TIME MAKING ANY HEADWAY AGAINST THE PREVAILING SOUTHWEST FLOW IN PALM BEACH COUNTY. STILL EXPECT SCT SHRA/TSRA TO CONTINUE PRIMARILY ALONG THIS CONVERGENT LINE AFFECTING AIRPORTS ALONG AND WEST OF THE FLORIDA TURNPIKE IN THE THREE METRO ATLANTIC COUNTIES. ULTIMATELY CONVERGENCE FROM LAKE BREEZES MEETING OUTFLOW BOUNDARIES WILL RESULT IN CONTINUED SHRA/TSRA ACROSS THE LAKE OKEECHOBEE REGION AND INLAND AREAS FARTHER SOUTH. FOR KAPF SOUTHWEST FLOW WILL CONTINUE WITH LESSER CHANCES OF SHRA/TSRA. OTHERWISE VFR CONDITIONS ARE EXPECTED TO PREVAIL WITH WINDS BECOMING LIGHT AND VARIABLE AFTER SUNSET. && .MARINE... THE WINDS WILL REMAIN FROM THE SOUTH TO SOUTHWEST DIRECTION AT 5 TO 10 KNOTS THROUGH FRIDAY...BEFORE SWINGING SLOWLY TO THE SOUTHEAST DIRECTION BY EARLY NEXT WEEK. THE SEAS WILL ALSO REMAIN BELOW 2 FEET THROUGH EARLY NEXT WEEK. SO BOATING CONDITIONS SHOULD BE GOOD OUTSIDE OF THE SHOWERS AND THUNDERSTORMS THIS WEEK INTO EARLY NEXT WEEK. && .FIRE WEATHER... THE RELATIVE HUMIDITIES WILL REMAIN ABOVE THE 35 PERCENT CRITICAL VALUE THIS WEEK INTO THIS WEEKEND. SO NO PROBLEMS WITH THE FIRE WEATHER. && .PRELIMINARY POINT TEMPS/POPS...
