AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE RALEIGH NC 600 PM EDT SAT AUG 11 2001 **********UPDATE******** MERGING OUTFLOWS AND MOIST VERY UNSTABLE AIRMASS WILL RESULT IN CONTINUED CONVECTIVE DEVELOPMENT ACROSS THE NORTHERN PIEDMONT... ESPECIALLY ALONG I-40 CORRIDOR BETWEEN THE TRIAD AND THE TRIANGLE. MSAS PLOTS AT 20Z & 21Z DEPICT BEST LOW LEVEL CONVERGENCE AND INSTABILITY IN THIS REGION. FINALLY...EARLIER CONVECTION OVER NORTHERN COASTAL PLAIN HAS DIMINISHED. THUS WILL LOWER POP IN THE AREA TO CHC. ************************ SUBSIDENCE HAS DONE A GOOD JOB HOLDING DOWN CONVECTION ACROSS CENTRAL NC TODAY. WILL PROBABLY TREND TO CLEAR TONIGHT DEPENDING ON BLOWOFF CIRRUS COVERAGE AS SUBSIDENCE CONTINUES THROUGH THE NIGHT AND SHOULD KILL ANY CONVECTION EARLY. WILL PERHAPS HAVE SOME 20/30 PERCENT EVENING POPS PENDING COVERAGE AT RELEASE. BASIC PATTERN CONTINUES AS WE REMAIN BLOCKED BETWEEN THE UPPER RIDGES THROUGH WEDNESDAY. CHANCE POPS WILL SUFFICE TOMORROW AND TOMORROW NIGHT. TEMPS IN THE UPPER 80S TO LOWER 90S...SIMILAR TO TODAY...LOOK GOOD. WILL PROBABLY STAY IN THE HIGH CHANCE CATEGORY MONDAY AS WELL ALTHOUGH WOULD EXPECT BETTER CHANCES WITH VORT AXIS FINALLY SHIFTING EAST OF THE MOUNTAINS. CLOUDINESS SHOULD BE MORE PREVALENT ON MONDAY AS WELL...BUT DONT THINK TEMPS WILL BE RETARDED INTO THE LOWER 80S DEPICTED ON THE MAV MOS. WILL KEEP CHANCES IN TUE DUE TO LACK OF CONFIDENCE IN TIMING OF THE TROFS LIFTING OUT. WILL STAY DRY WED AND THU AS BERMUDA HIGH TEMPORARILY REASSERTS ITSELF PRIOR TO FROPA ARRIVAL BY EARLY IN THE WEEKEND. .RAH...NONE. MLM/WSS
