WHAT HAS CHANGED
WINTER STORM WATCH IS NOW IN EFFECT FOR SUMMERS CO, WV AND THE
WESTERN PORTION OF GREENBRIER COUNTY, WV FROM 1AM ON SUNDAY
THROUGH 7PM ON MONDAY. SNOWFALL IN THIS AREA DURING THIS TIME
FRAME MAY RANGE FROM SIX TO TEN INCHES.
KEY MESSAGE
1) SIGNIFICANT UPSLOPE SNOW FOR PORTIONS OF THE MOUNTAINS HAS
TRIGGERED THE ISSUANCE OF A WINTER STORM WATCH FOR WESTERN
GREENBRIER AND SUMMERS COUNTIES SUNDAY AND MONDAY. LESSER SNOW AND
RAIN EXPECTED IN OTHER AREAS.
DISCUSSION
KEY MESSAGE 1:
A GREAT LAKES MID-LEVEL SHORTWAVE WILL TRACK SOUTH INTO THE MID-
ATLANTIC, WHILE A SURFACE LOW WILL MAKE ALMOST MIRROR MOVEMENTS,
MOVING FROM THE SOUTH TOWARDS THE CAROLINAS. THESE TWO FEATURES WILL
COMBINE AND INSTIGATE RAPID INTENSIFICATION NEAR THE VA/NC ATLANTIC
COAST. AS THIS SYSTEM CONTINUES TO INTENSIFY, THE WIND FIELD WILL
STRENGTHEN AND EXPAND, ADVECTING COLDER AIR INTO THE AREA, AND
ENHANCING UPSLOPE EFFECTS IN THE WESTERN SLOPES OF THE MOUNTAINS.
ENSEMBLE GUIDANCE HAS BEEN SPLIT, WITH MEMBERS OF EVEN THE SAME
ENSEMBLE FALLING INTO DISTINCT CAMPS. THE FIRST CAMP HAS THE
INTENSIFYING STORM HOLD FAIRLY TIGHT TO THE COASTLINE, STAYING
CLOSER TO OUR MOUNTAINS, AND MAINTAINING UPSLOPE AND COLD AIR
ADVECTION FOR A LONGER PERIOD THROUGH SUNDAY. THIS WOULD INCREASE
THE EXPECTED SNOW IMPACTS. THE LATTER CAMP HAS MORE OF A WESTERLY
DRIFT, SHUTTING OFF THE TWO AFOREMENTIONED FACTORS EARLIER, LEADING
TO A LESS IMPACTFUL EVENT. THE FORECAST REFLECTS AN ATTEMPT TO SPLIT
THE DIFFERENCE, PLACING HIGHER SNOW AMOUNTS OF 5-10" IN THE HIGHEST
ELEVATION PORTIONS OF OUR WV MOUNTAINS (W. GREENBRIER), WITH LESSER
IMPACTS EVEN ONE COUNTY EAST OF THAT, WITH LITTLE TO NO SNOW
EXPECTED NEARER TO THE BLUE RIDGE.
IDEALLY, IN THE NEXT 24 HOURS THERE WILL BE SOME MORE AGREEMENT
AMONGST ENSEMBLES AND DETERMINISTIC GUIDANCE TO ALLOW A HIGHER
CONFIDENCE FORECAST.
SNOW IS THE BIG HEADLINE FOR THIS WEEKEND, WITH RAIN TURNING TO SNOW
STARTING EARLY SUNDAY MORNING AND CONTINUING THROUGH EARLY MONDAY
MORNING. OTHER AREAS FURTHER EAST WILL EXPERIENCE A FULLY LIQUID
RAIN EVENT FROM SATURDAY EVENING THROUGH TO SUNDAY AFTERNOON. MOST
AREAS WILL RECEIVE A QUARTER TO TWO THIRDS OF AN INCH OF RAIN OVER
THE DURATION OF THIS EVENT.
AN ADDITIONAL HAZARD DURING THIS ENTIRE EVENT WILL BE WIDESPREAD
STRONG WIND GUSTS. RAIN OR SNOW, FOLKS CAN EXPECT TO FEEL GUSTS OF
25-35 MPH, EVEN REACHING UP TO 40 MPH ALONG RIDGES AND IN HIGHER
ELEVATIONS. THIS COULD PROVE PARTICULAR DANGEROUS IN THE AREAS UNDER
A WINTER STORM WATCH AS SNOW WILL BLOW AND DRIFT, FURTHER REDUCING
VISIBILITY AND THE DANGER OF DRIVING DURING AND AFTER THE EVENT.
AVIATION /18Z FRIDAY THROUGH WEDNESDAY/
VFR CONDITIONS HAVE ARRIVED ACROSS THE ALL BUT THE FAR EASTERN
SECTION OF THE REGION. AT BEST, WITHIN AN HOUR, THESE LOCATIONS
WE ALSO SEE CEILINGS IMPROVE TO VFR.
WINDS HAVE BEEN INCREASING FROM WEST TO EAST BEHIND THE PASSAGE
OF A COLD FRONT. GUSTS OF 25 TO 35 KTS FROM THE WEST HAVE BEEN
COMMON ACROSS THE MOUNTAINS IN THE WAKE OF THE FRONT. SIMILAR
WIND GUSTS ARE EXPECTED TO CONTINUE THROUGH THE EARLY EVENING.
LOCATIONS EAST OF THE MOUNTAINS MAY SEE GUSTS PERHAPS IN THE 20
TO 30 KT RANGE BY THE MID-AFTERNOON.
FOR ALL LOCATIONS, WINDS WILL TREND DOWNWARD THROUGH THE
OVERNIGHT HOURS, WITH LIGHT AND VARIABLE CONDITIONS EXPECTED BY
DAYBREAK SATURDAY.
VFR CONDITIONS ARE EXPECTED THROUGH THE DURATION OF THE VALID
TAF PERIOD, CONCLUDING 18Z/1PM SATURDAY.
EXTENDED AVIATION OUTLOOK...
INCREASED AREAS OF SUB-VFR CONDITIONS SATURDAY NIGHT HEADING
INTO SUNDAY THANKS TO SNOW AND RAIN ARRIVING ACROSS THE REGION.
SNOW WILL BE MOST ABUNDANT ACROSS THE MOUNTAINS WITH RAIN FOR
THE PIEDMONT.
FLIGHT CATEGORIES IMPROVE FOR THE PIEDMONT SUNDAY NIGHT INTO
MONDAY THANKS TO AN INCREASING VERY GUSTY NORTHWEST WIND
BRINGING A CONCLUSION TO THE PRECIPITATION AND PARTIAL ERODING
OF CLOUD COVER.
ACROSS THE MOUNTAINS SUNDAY NIGHT INTO MONDAY, THE GUSTY
NORTHWEST WINDS (30 TO 40 KTS) WILL YIELD A CONTINUATION OF
SUB- VFR CONDITIONS AND A PROLONGED PERIOD OF SNOW SHOWERS.
VFR CONDITIONS RETURN FOR THE ENTIRE AREA BY TUESDAY INTO
TUESDAY NIGHT.
FOR WEDNESDAY, A COLD FRONT MAY BRING SOME LIGHT RAIN SHOWERS TO
WESTERN SECTIONS ALONG WITH POCKETS OF SUB-VFR CONDITIONS. GUSTY
NORTHWEST WINDS ARE EXPECTED.
