Airline spokeswoman Valerie Wunder says nobody was injured. Wunder says flight 4376 operated by the US Airways subsidiary Piedmont was en route from Charlotte, N.C., to Lynchburg, Va., when it was struck by lightning 20 miles south of its destination Wednesday.
She says the pilot declared an emergency and landed at the Lynchburg airport without incident. There were 13 passengers and three crew members aboard the Dash 8-300 twin turboprop aircraft.
Federal Aviation Administration spokesman Jim Peters says the pilot reported an electrical failure. Peters says the FAA will investigate.

TEMPS JUST BELOW FREEZING AT THAT TIME...ICE CRYSTAL FORMATION IS
NOT EXPECTED UNTIL MONDAY MORNING. SHOULD A TRACE OF ICE ACCRETION
BE EXPECTED...A WINTER WEATHER ADVISORY WOULD BE NEEDED TO BE ISSUED
BY LATER SHIFTS. MIN TEMPS TONIGHT MID TO UPPER TEENS UP ALONG THE
MASON-DIXON WHERE LATE NIGHT CLEARING IS EXPECTED. MID TO UPPER 20S
ACROSS THE BALT-WASH METRO AND SOUTH...AND THE SHENANDOAH VALLEY.
&&
.SHORT TERM /MONDAY/...
INCREASING AND EXPANDING ELY FLOW WILL MAKE FOR OVERCAST
LOW CLOUDS. ISENTROPIC LIFT THROUGH THE CLOUD LAYER/TEMPERATURE
INVERSION SHOULD ALLOW FOR A LIGHT WINTRY MIX TO SPREAD NORTHEAST
ACROSS THE CWA BY THE LATE AFTERNOON. BOTTOM LINE...CONFIDENCE IS
LOW...SO CHANCE POPS ARE GIVEN. ANY PRECIP THAT FORMS IS EXPECTED TO
BE VERY LIGHT THROUGH MONDAY. MAX TEMPS LOW 30S...UPPER 20S
NORTH...MID 30S SOUTH.
&&
.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
ON MON NGT THERE'LL BE AN AREA OF STRONG HIGH PRES (PRSNTLY CENTRAL
PRES OVR LAKE WINNEPEG IS 1041 MB) MOVG OVR NY STATE WHICH WL LEAD
TO CAD DOWN THE E SIDE OF THE APLCHNS. AT SAME TIME A WARM FNT WL BE
XTNDG ACROSS THE SERN STATES TO THE ATLC CST. MID ATLC WL BE IN AN
OVERRUNNING SITUATION. QUSTN IS HOW MUCH QPF WL BE GENERATED IN THIS
ENVIRONMENT...AND WHAT POPS TO CHOOSE? NAM IS SHOWING CAT WHILE GFS
IS GNRLY HIGH CHC. TO MAKE IT TOUGHER IT'S LOOKING LK THE BULK
OF PCPN WL BE OCCURRING N OF THE MASON-DIXON LN. FOR NOW I'LL STAY
W/ THE HIGH CHC SCENARIO GIVEN A LACK OF FORCING. P-TYPE BEGINNING
MON NGT WL RANGE FM ZR/IP IN THE CENTRAL SHEN VLLY TO CHC S N OF THE
PTMC RVR...W/ MIXING GOING ON IN ALL XCPT NE MD BY MRNG. QPFS WL BE
LGT...BUT IF ANY FRZG RA DOES DVLP AN ADVISORY WL BE NEEDED. BUT IT
IS MUCH TOO EARLY TO DO THAT NOW.
THE COLD AIR MAY BE DIFFICULT TO DISLODGE TUE MRNG...ESPECIALLY IN
"THE USUAL SUSPECT" - THE ERN PANHANDLE OF WV/NW VA/W CENTRAL MD. AS
W/ MON NGT THE BEST FORCING TO CAUSE PCPN WL BE ACROSS PA DURG
...SO WL MAINTAIN THE CHC POPS W/ LOW QPF TUE. IN CENTRAL SHEN
VLLY/LOWER SRN MD/DC PCPN CHC WL CHG TO PLAIN RA AFTR MID MRNG.
TEMPS TUE RANGE FM A40 CENTRAL SHEN VLLY TO L30S ALONG THE MD BRDR.
TUE NGT IS WHEN WE XPCT THE BULK OF THE PCPN TO FALL IN OUR CWA
AHEAD OF THE CD FNT. WE HV LKLY/CAT POPS DURG THAT PD. WARMER AIR
WL BE MOVG ACROSS THE ERN U.S. ALTHO THE SUB 130 DM (LO LVL COLD
POOL) MAY STILL HV TROUBLE BEING SCOURED FM THE USUAL SUSPECT.
P-TYPE FOR MAJORITY OF CWA AFTR MDNGT WL BE RA. IT BECOMES MORE
QUSTNBL CLOSER TO THE PA BRDR. TEMPS TUE NGT IN THE 30S - MAJORITY
OF THE CWA AT SFC WL RMN ON THE PLUS SIDE OF THE FRZNG LN. I'M
SURE THERE'LL BE ADJUSTMENTS TO THE TEMPS AND P-TYPE IN THE COMING
DAYS.
ACTUALLY - IN SPITE OF ALL THIS DSCN OF TEMP AND P-TYPE I THINK
THERE'S A CHC THAT THE BIG WX MAKER OUT OF THIS LOW PRES/FNT WL BE
THE WIND XPRNCD AFTR FROPA ON WED. WED NGT AND THU WL HV THE PTNL
TO BE QUITE WINDY. IN ADTN THE UPSLOPE SNOW MACHINE WL GET TURNED
ON AGN FOR THE WRN SLOPES OF THE HIGHLANDS THRU THU.
AFTR THAT A MUCH NEEDED RESPITE SHOULD BE ON THE WAY AS HIGH PRES
BUILDS INTO THE ERN U.S. THU NGT AND FRI. NGTS WL BE COLD AS TEMPS
DROP BACK INTO THE TEENS BUT IT WON'T BE COLDER THAN WHAT HAS BEEN
XPRNCD ALREADY THIS MONTH.
THERE IS A DISCREPANCY BTWN THE GFS AND ECMWF REGARDING A PSBL CSTL
STORM NEXT WKND - ONE HAS IT OFF OF ORF ON SAT WHILE THE OTHER ON
SUN. FOR NOW WE'LL KEEP OUR FCST BASED ON THE SAT POSN. THERE WL BE
MANY TWEAKS IN THAT FCST IN THE DAYS AHD.
&&
.AVIATION /THIS EVENING THROUGH FRIDAY/...
NLY/NELY FLOW WILL INCREASE LOW LEVEL NEAR MVFR CLOUDS THIS EVENING
THAT WILL PERSIST AT LEAST THROUGH MONDAY. CHANCES FOR A LIGHT
WINTRY MIX WILL SPREAD NORTHEAST LATE TONIGHT THROUGH MONDAY.
SWLY FLOW AHEAD OF A DEVELOPING STORM SYSTEM OVER THE SRN CONUS
WILL BRING INCREASING CHANCES FOR LIGHT WINTRY PRECIP MON AND TUE.
PTYPES ARE STILL UNCERTAIN AT THIS TIME...BUT PRECIP WILL MOST LIKELY
TRANSITION FROM A SN/IP MIX TO -ZR MON NGT INTO TUE. SUBVFR
CONDITIONS ALSO EXPECTED DURING THIS TIME. THE STORM SYSTEM WILL
TRACK UP THE WRN SIDE OF THE APPALACHIANS TUE NGT INTO WED...
BRINGING HEAVIER PRECIP INTO THE AREA. PRECIP WILL EVENTUALLY
CHANGE OVER TO RAIN TUE NGT AS WARMER AIR WORKS INTO THE AREA.
STRONG GUSTY WINDS PSBL WED NGT AND THU AT ALL TAF SITES.

.MARINE...
HIGH PRESSURE TO THE NORTH WILL INCREASE A NLY THEN NELY FLOW ACROSS
THE MD CHES BAY TONIGHT THROUGH MONDAY. NLY CHANNELING MAY REACH
MARGINAL SCA CRIT TONIGHT...WINDS CAPPED AT 15 KT ATTM. FLOW BECOMES
ELY MONDAY.
