AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WAKEFIELD VA 134 PM EDT WED JUL 16 1997 MAY NOT BE QUITE AS WARM AS YESTERDAY BUT APPEARS DEWPOINTS MAKING UP FOR THE LOSS OF A FEW DEGREES AS FAR AS THE COMFORT DEPARTMENT IS CONCERNED. DEWPOINTS NOW IN THE LOW TO MID 70S MOST OF THE AREA. THUNDERSTORMS HAVE POPPED JUST WEST OF THE AKQ RED LINE BETWEEN DAN AND SHD...AND THEY BE A CREEPING EASTWARD DUMPING COPIOUS RAINFALL. AKQ 88D ESTIMATES HAVE 1 HOUR TOTALS NEAR 3 INCHES ACROSS AMHERST COUNTY. ACCORDING TO 500 TEMPS VIL O THE DAY AROUND 61. PULSE SEVERE POSSIBLE THIS AFTERNOON...BUT THINK FLASH-FLOODING WILL BE MAJOR FEATURE WITH HEAVY RAINS AND CEMENT-LIKE GROUND. THINGS LIKELY TO PROGRESS SLOWLY EASTWARD THIS AFTERNOON AS TROF EASES ALONG. HOWEVER AS IT GETS A LITTLE FURTHER EAST IT SHOULD STALL...ACCORDING TO THE MODELS. ETA NEVER REALLY GIVES US A WINDSHIFT THRU THE 48 HR PERIOD. WITH PATTERN AS STAGNANT AS IT IS...THIS SEEMS LOGICAL. NOT MUCH IN THE WAY OF SHORTWAVE ENERGY COMING FROM THE WEST...HOWEVER LOW OVER SOUTHEAST WILL SPIN VORT LOBE INTO NORTH CAROLINA TONIGHT. THIS THEN GETS CAUGHT UP IN BAGGY TROF AND MOVES VERY SLOWLY NORTH AND EAST TOMORROW AND TOMORROW NIGHT. THIS COULD PROVE TO BE FOCUS FOR MORE CONVECTION TOMORROW AFTERNOON. THINK SMALL POPS FOR EASTERN ZONES WOULD BE PRUDENT FOR THURSDAY. CWF...NO FLAGS NEEDED. RIC...71/94/72/95 3212 ORF...75/92/75/92 3312 SBY...72/92/71/93 3312 ECG...74/91/74/92 4322 VALONE
