(TONIGHT AND TOMORROW)...UPPER LOW CONTINUES LIFTING NORTH NORTHEAST OVERNIGHT AS IT GETS SWEPT UP BY WEAK INCOMING UPPER TROUGH. BOTH OF THESE FEATURES ARE RATHER WEAK AS THEY MERGE TOGETHER AND SHOULDN`T POSE A THREAT FOR ANY WIDESPREAD RAINS. WILL HAVE CHANCE AND SLIGHT CHANCE SHOWERS IN OVERNIGHT. FOG IS TOUGH TO FIGURE OUT TONIGHT DUE TO UNCERTAINTY OF PRECIP COVERAGE AND HOW MUCH CLEARING...IF ANY...CAN TAKE PLACE TOWARD EARLY MORNING. NOT ENOUGH CONFIDENCE TO PUT PATCHY FOG WORDING IN ZONES BUT A FEW ISOLATED AREAS OF FOG CAN`T BE RULED OUT FOR LOCATIONS THAT SEE RAIN. LOWS WILL BE NEAR NORMAL TONIGHT. FOR TOMORROW...PWS REMAIN SOMEWHAT ELEVATED BUT THERE JUST ISN`T ANY STRONG FORCING PRESENT TO GENERATE MUCH IN THE WAY OF CONVECTION OR PRECIP FOR THAT MATTER. WILL HAVE CHANCE AND SLIGHT CHANCE POPS IN FOR TOMORROW WITH SLIGHT CHANCE OF A THUNDERSTORM DURING THE AFTERNOON HOURS. MAX TEMPS TOMORROW EXPECTED TO BE A FEW DEGREES BELOW NORMAL. .LONG TERM...(TOMORROW NIGHT THROUGH SUNDAY)...FIRST HALF OF NEXT WEEK LOOKS TO REMAIN MOSTLY DRY FOR MUCH OF THE AREA AS THE UPPER TROUGH MOVES OFF TO OUR EAST AND TAKES AWAY MOST OF THE MOISTURE WITH IT. WE LOOK TO REMAIN RELATIVELY DRY AFTER THAT, WITH THE NEXT ROUND OF MOISTURE POSSIBLY MOVING IN WITH WHAT LITTLE REMAINS OF ERIKA. ISOLATED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE, BUT COVERAGE IS NOT EXPECTED TO BE VERY WIDE. BETTER CHANCES WILL LIKELY HAVE TO WAIT TILL CLOSER TO THE WEEKEND WHEN MOISTURE RETURNS WITH SOUTHERLY FLOW AHEAD OF ANOTHER TROUGH MOVING IN FROM THE WEST. DUE TO DECREASE IN RAIN CHANCES AND CLOUD COVERAGE, HAVE GONE AHEAD WITH THE ABOVE AVERAGE TEMPERATURES WITH SOME PLACES REACHING NEAR 90 DEGREES NEXT WEEK.
