WILL MENTION "WITH HEAVY RAIN" THROUGH THE NORTHEASTERN COUNTIES TONIGHT. WON'T GO WITH FLASH FLOOD WATCH SINCE FFG NUMBERS REMAIN HIGH AND RAINS DURING THE MORNING DIDN'T PRODUCE ANY PROBLEMS EVEN THOUGH 4.4" FELL AT ONE LOCATION. ALTHOUGH THERE WILL BE SOME RESIDUAL RAIN THURSDAY MORNING THROUGH THE EXTREME EASTERN COUNTIES...MOST OF THE AREA WILL BE DRY UNTIL THE ARRIVAL OF THE COLD FRONT LATE THURSDAY AFTERNOON AND INTO THE EVENING.
