AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC 315 PM EDT THU JUN 22 2006 .SHORT TERM...TONIGHT AND FRIDAY... SEVERAL CONCERNS IN THE SHORT TERM AS WELL AS LONG TERM FCSTS. OUR EYES FOCUS THIS AFTN TO THE CONVECTION OCCURRING IN SE OH...BUILDING INTO NRN WV AND FAR WRN PA. THIS ACTIVITY IS OCCURRING IN RELATION TO A STRONG S/W MOVING TO THE EAST. WE EXAMINE THE MID LVL HGTS AND SEE THAT THE PATTERN BRINGS THIS S/W ENE ACROSS SRN PA...WHILE SKIFFING WRN MD. MEANWHILE STRONG MID LVL HIGH REMAINS PLANTED ACROSS OUR SRN CWFA AND ESP FURTHER SOUTH WHERE THE WARM TEMPS ALOFT ARE SUPPORTING HOT TEMPS. SPC HAS BEEN VERY CONSISTENT THE LAST FEW OUTLOOKS WITH HIGHLIGHTING OUR NRN CWFA FOR A SLGT RISK FOR SVR. BELIEVE THIS IS STILL THE CASE FOR THIS EVENING...WHERE THE BEST CHC FOR SVR TSTMS AND PRECIP IN GENERAL WILL BE CLOSEST TO THE TRACK OF THE MID LVL ENERGY. THEREFORE HAVE INDICATED SCTD EVNG CONVECTION ACROSS THE NW AND FAR NORTH WITH JUST ISO TSTMS ELSEWHERE THIS EVNG. CONVECTIVE PARAMETERS ARE WORTH NOTING THIS AFTN...VERY STRONG SFC INSTAB WITH CAPE APPROACHING 4000J/KG AND MODEL LI -6 TO -8. HWVR LAPSE ANALYSIS SHOWS THAT THE MORNING MID LVL CLOUDINESS WHICH HAS IMPACTED MUCH OF OUR AREA HAS HELPED TO DAMPEN THE INTENSITY OF INSTAB. LATER TNGT WILL MAINTAIN HIGHER CHC POPS IN THE N AND CONTINUE 20S IN THE SOUTH. THERE IS A CHC OF HIGHER PRECIP COVERAGE IN THE SOUTH DUE TO POSSIBLE REMNANT MESO BNDRYS HWVR THE FACT OF POOR SHEAR...DOWNSLOPE (EVIDENCE LATEST VWP) AND DECREASING LOW LVL MOISTURE IN THE SOUTH IS OUR REASON FOR LACK OF PRECIP COVERAGE OUTSIDE OF WRN AND N CTRL MD AND FAR NRN E WV PANHANDLE. ON FRIDAY THERE ARE AGAIN SOME TRICKY ISSUES IN THE FCST. THE GNRL IDEA OF ACTIVITY BEING FOCUSED IN THE NRN MOST CWFA REMAINS. BELIEVE BEST FORCING WILL BE IN THE FAR NRN AREA AND ESP N OF THE MASON/DIXON. HAVE ADDED CAT POPS IN THE N ON FRIDAY WITH CHC IN THE SOUTH. THIS IS SOMEWHAT IN AGREEMENT WITH GFS MOS POPS ALTHOUGH UNDERCUT A BIT IN THE SOUTH. && .AVIATION... FOG IS A CONCERN FOR LATE TNGT. HAVE INDICATED IFR FOG CONDS AT THE MORE PRONE/CLIMO SITES SUCH AS IAD/MRB/CHO. IF THOSE LOCATIONS GET ANY RAIN ALONG WITH THE HIGHER DEWPOINTS EXPECTED OVERNGT THERE COULD BE A POTENTIAL FOR DENSE FOG. && .MARINE... NO MARINE CONCERNS AT THIS TIME. && .LONG TERM (FRI NIGHT-THU) FRONTAL BDRY WILL STALL OVR THE AREA THIS WEEKEND AND BE FOCUS FOR HEAVY RAIN. SWRLY UPPER FLOW ALONG WITH HIGH PW AIR AND SERIES OF WAVES WILL ENHANCE PRECIP COVERAGE AND POTENTIAL FOR SMALL STREAM FLOODING. HPC DY1-5 QPF SHOW A MAX OF 7.5 INCHES THRU 12Z TUE. WILL CONTINUE WITH HYDROLOGIC OUTLOOK AND HOLD OFF ON FLOOD WATCH FOR NOW. ROSA .LWX WATCHES/WARNINGS/ADVISORIES... DC...NONE. MD...NONE. VA...NONE. WV...NONE. MARINE...NONE. && JB/LFR
