ADDITIONAL ISOLD CELLS DEVELOPED ACROSS AL/GA COUNTIES. WEAK LOW/MID LEVEL FLOW WILL FAVOR BRIEF PULSE STORMS AND A FEW CAN GENERATE GUSTY WINDS INTO THIS EVE. ALSO CANNOT DISCOUNT BRIEF SEVERE STORM WITH MICROBURSTS AND DAMAGING WINDS. THERE WERE VARIOUS REPORTS OF WATERSPOUTS THIS MORNING AND AFTERNOON IN THE VICINITY OF APALACHICOLA. AT UPPER LEVELS...

THE LONG TERM PERIOD BEGINS WITH RIDGING EXTENDING FROM SOUTHERN CALIFORNIA EASTWARD TO THE TENNESSEE RIVER VALLEY. THERE IS A BREAK BETWEEN THIS LARGE RIDGE AND THE BERMUDA RIDGE JUST OFF THE CAROLINA COAST DUE TO A DEPARTING EAST COAST TROF. WITH THE RIDGING REMAINING IN PLACE INTO AT LEAST MONDAY...POP CHANCES WILL REMAIN RELATIVELY LOW AND CONFINED PRIMARILY TO THE SEA BREEZE ZONE IN THE AFTERNOON. TEMPERATURES WILL RETURN TO NEAR THE 100 DEGREE MARK. RECORD HIGH TEMPERATURES FOR TALLAHASSEE FOR THE FIRST PART OF JULY ARE IN THE MID 100S (1931)...WHICH WITH THE EXPECTED PATTERN SHOULD BE SAFE. BY TUESDAY...THE LARGE UPPER LOW OVER THE HUDSON BAY WILL DEEPEN AS IT SURGES SOUTHEASTWARD INTO THE ST LAWRENCE RIVER VALLEY. THIS WILL RESULT IN THE LARGE RIDGE RETREATING WESTWARD...WHILE THE EASTERN COMPONENT WEAKENS CONSIDERABLY...CREATING A GAP BETWEEN THE WESTERN CONUS RIDGE AND THE BERMUDA RIDGE. AS THIS OCCURS ON TUESDAY...AN INCREASE IN MOISTURE IS EXPECTED TO ARRIVE FROM THE SOUTHERN GULF OF MEXICO IN ASSOCIATION WITH A WESTWARD MOVING TROPICAL WAVE. RAIN CHANCES WILL BE ON THE RISE AS DEEP LAYER MOISTURE INCREASES AS WELL. MAX TEMPS WILL ALSO DROP OFF INTO THE MID 90S. && .MARINE... A TROUGH NEAR THE COAST WILL GRADUALLY SETTLE SWD ACROSS THE WATERS WITH HIGH PRESSURE BECOMING ESTABLISHED TO THE N. THIS WILL CREATED A PERIOD OF RATHER LIGHT WINDS WITH SEA BREEZE DOMINATING THIS AFTERNOON INTO FRI WITH WINDS SWITCHING AROUND TO THE E BY SAT. CONVECTIVE COVERAGE OVER THE WATERS WILL CONTINUE TO MAXIMIZE DURING THE EARLY MORNING HOURS AND DROP OFF DURING THE MIDDAY TO AFTERNOON HOURS. TS ARLENE WILL GENERATE SOME SWELLS WHICH WILL MOVE NEWD AND LIKELY INCREASE RIP CURRENT RISK BY LATE WEEKEND.... ESPECIALLY OVER PANHANDLE BEACHES. && .AVIATION...

CONVECTION WILL DISSIPATE WITH THE SETTING OF THE SUN THIS EVENING GIVING WAY TO PREVAILING VFR CONDITIONS THROUGH MUCH OF THE OVERNIGHT. PATCHES OF MVFR VIS ARE POSSIBLE TOWARD DAWN...ESPECIALLY FOR THOSE TERMINALS WHICH RECEIVE MEASURABLE RAINFALL TODAY. && .FIRE WEATHER...
