Pretty rare to get thunderstorms moving in from the NW, and six hours later have more moving up from the SW.

I think they were running down the base of the near-surface warm front. The whole batch was slowly moving north/NE with the cells running southeast along it. Now the upper level warm front is pushing through so the flow is fully from the sw.

Awesome pics Hank! I caught the following using my Wife's P & S just down the road from you at 7:59 pm:

Two minutes later, I managed to catch a few decent bolts but the results didn't come out so well so I, umm, touched up the next pic. I should probably get my own camera:

Probably Sprites which appear as luminous reddish-orange flashes.

HAH no. Sprites occur visibly waaaaay up above the clouds, and they are difficult to see with the naked eye. The most likely cause would be contaminants in the air between you and the bolt that would absorb the other visible wavelengths, leaving only a reddish-looking bolt.

Ya probably all the haze.

..CNTRL APPALACHIAN MTNS/MID-ATLANTIC

AN UPPER-LEVEL RIDGE WILL MOVE EWD INTO THE NRN APPALACHIAN MTNS AS

AN UPPER-LEVEL TROUGH APPROACHES THE REGION FROM THE SOUTHWEST. ON

THE WRN EDGE OF THE UPPER-LEVEL RIDGE... AN AXIS OF MODERATE TO

STRONG INSTABILITY IS FORECAST TO DEVELOP FROM WCNTRL PA SSEWD INTO

MD AND ERN VA. THUNDERSTORMS SHOULD INITIATE IN THE HIGHER TERRAIN

OF THE CNTRL APPALACHIAN MTNS AND MOVE EWD ACROSS THE INSTABILITY

AXIS THIS AFTERNOON. FORECAST SOUNDINGS ALONG THIS CORRIDOR AT 21Z

SHOW MLCAPE VALUES IN THE 2000 TO 3000 J/KG RANGE ALONG WITH 40 TO

45 KT OF DEEP LAYER SHEAR. ALTHOUGH THIS SHOULD BE SUFFICIENT FOR

SUPERCELLS AND ISOLATED LARGE HAIL...CONVECTION MAY TEND TO LINE

OUT. THIS WOULD FAVOR WIND DAMAGE AS THE GREATER THREAT THIS

AFTERNOON IN THE MID-ATLANTIC REGION.

LWX morning disc

THE EXPECTED CLOUD COVER WILL LIMIT DAYTIME HEATING SOMEWHAT AND

LIKELY DELAY ONSET OF DIURNAL CONVECTION UNTIL THE ERY TO MID AFTN.

CONVECTION WILL LIKELY FORM ALONG A SFC TROUGH FORMING ON THE LEE

SIDE OF THE BLUE RIDGE AS LIFT FROM THE UPPER DISTURBANCE BECOMES

JUXTAPOSED WITH CONVERGENCE ALONG THE SFC TROUGH. LOCAL WRF-ARW

AND HRRR-WRF SIMULATES CONVECTION ORGANIZING INTO BKN LINE

SEGMENTS EAST OF THE BLUE RIDGE DURING THE MID AFTN. AMOUNT OF

INSTABILITY AND SEVERE POTENTIAL WILL DEPEND ON AMOUNT OF BREAKS IN

CLOUD COVER. BASED ON CURRENT FCST OF AFTN TEMPS IN THE UPPER

80S...DEWPOINTS IN THE LOW 70S AND MODEST BUT STEEPENING LAPSE

RATES SHOULD YIELD MODERATE CAPE VALUES EAST OF THE BLUE RIDGE.

COMBINED WITH DEEP-LAYER SHEAR VALUES OF 30-35 KT...THERE IS A

POTENTIAL FOR STORMS TO ORGANIZE AND BECOME SEVERE WITH DAMAGING

WINDS AND LARGE HAIL ACROSS THE ERN HALF OF THE CWA. HAIL THREAT

WILL BE LIMITED SOMEWHAT BY WARM THERMAL PROFILES THOUGH. SPC HAS

PLACED AREAS EAST OF THE BLUE RIDGE IN A SLIGHT RISK TDA.

CONVECTION WILL LIKELY CONTINUE DURING THE FIRST HALF OF THE EVE

ALONG AND EAST OF I-95 AS THE SFC TROUGH PROGRESSES EWD...BEFORE

WANING DURING THE LATE EVE WITH THE LOSS OF DAYTIME HEATING. LOW

CHANCES FOR SHOWERS AND PERHAPS A TSTM WILL LINGER INTO THE OVNGT

AS ANOTHER WEAK DISTURBANCE APPROACHES FROM THE WEST.-- End Changed Discussion --
