AVIATION UPDATE, IN WHICH THERE MAY BE VISIBILITY RESTRICTIONS
IN SHOWERS MONDAY. RAISED POPS TO THE LATEST NBM VALUES, BUT
STILL SHORT OF LIKELY.
PREVIOUS, AS OF 204 PM SUNDAY...

IN FROM THE WEST TONIGHT INTO MONDAY. A MARGINAL RISK FOR
EXCESSIVE RAINFALL WAS ALSO INTRODUCED FOR THE CENTRAL
APPALACHIANS FOR WEDNESDAY INTO THURSDAY WITH A COLD FRONT.

THE START OF THE WEEK, FOLLOWED BY A COLD FRONT FEATURING HIGHER
CHANCES OF SHOWERS AND STORMS.
2) COLDER AIR ON THE BACKSIDE OF THE COLD FRONT ADVERTISES
CHILLY NIGHTS AND A MOUNTAINOUS WINTRY MIX FOR THE END OF THE
WEEK.
DISCUSSION
KEY MESSAGE 1...
AFTER A PLEASANT CONCLUSION TO THE WEEKEND, CHANCES FOR RAIN
RETURN TO THE FORECAST STARTING OVERNIGHT INTO MONDAY MORNING AS
SHORTWAVE TROUGH AND A SMALL AREA OF A STRENGTHENING LOW LEVEL
JET PIVOT INTO THE REGION. MID-LEVEL CLOUDS FIRST INVADE FROM
THE NORTHWEST AROUND SUNSET THIS EVENING, FULLY ENCASING THE
FORECAST AREA IN A BLANKET OF OVERCAST SKIES BY MIDNIGHT. ENOUGH
MOISTURE DIVING INTO THE AREA MAY SUPPORT A LIGHT SHOWER OR TWO
LATE TONIGHT ACROSS SOUTHEAST OH/NORTHEAST KY DOWN INTO THE
SOUTHERN COALFIELDS OF WEST VIRGINIA, BUT MAY BARELY REGISTER A
FEW HUNDREDTHS OF PRECIPITATION IN THE PROCESS. ON AND OFF
SHOWERS AND PERHAPS A RUMBLE OF THUNDER IN THE AFTERNOON
CONTINUES INTO THE DAY MONDAY.
LOW LEVEL SOUTHERLY FLOW WILL CONTINUE TO PULL IN MOISTURE ON
TUESDAY OUT AHEAD OF A COLD FRONT SLATED TO ARRIVE BEFORE THE
MIDDLE OF THE WEEK. THE FRONT GALLIVANTS THROUGH THE FORECAST
AREA AT A SLUGGISH PACE, BECOMING NEARLY STATIONARY IN THE
PROCESS, WHICH WILL SET THE STAGE FOR PERIODS OF MODERATE TO
HEAVY RAIN FOR WEDNESDAY AND INTO PARTS OF THURSDAY. THIS WILL
BE ESPECIALLY TRUE IN THE EVENT AN INFLUX OF MOISTURE RIDES
FURTHER NORTHWARD ALONG THE BOUNDARY THAN CURRENTLY HINTED UPON
BY MODEL GUIDANCE.
WPC HAS PLACED THE CENTRAL APPALACHIANS IN A MARGINAL RISK FOR
EXCESSIVE RAINFALL IN THEIR DAY 4 (12Z WEDNESDAY TO 12Z
THURSDAY) OUTLOOK, WITH A SLIGHT RISK LOOMING IN THE MISSISSIPPI
BASIN WHERE THE LOBE OF HEAVIER RAINFALL IS ANTICIPATED TO TAKE
PLACE. DROUGHT CONDITIONS IN THE FORECAST AREA AHEAD OF THIS
SYSTEM SHOULD HELP TO EVADE FLOODING CONCERNS INITIALLY WITH THE
ONSET OF RAINFALL. LONGEVITY AND EXTENT OF RAIN, HOWEVER, COULD
EVENTUALLY OVERWHELM SOILS IN A LOCALIZED CAPACITY.
KEY MESSAGE 2...
IN THE WAKE OF THE COLD FRONTAL PASSAGE, COLDER AIR NAVIGATES
DOWN INTO THE AREA FOR THE END OF THE WEEK. THIS WILL IMPOSE
OVERNIGHT TEMPERATURES TO BOTTOM OUT NEAR FREEZING FOR SOME
THURSDAY NIGHT. ADDITIONALLY, LINGERING MOISTURE ALONG THE
HIGHER TERRAIN THURSDAY NIGHT COULD CHANGE OVER TO A WINTRY MIX
AMID THESE COLDER TEMPERATURES.
AVIATION /06Z MONDAY THROUGH FRIDAY/
MAINLY VFR CONDITIONS EXPECTED FOR THE PERIOD. SOUTHWESTERLY WINDS,
WITH OCCASIONAL GUSTS IN THE TEENS TO LOWER 20 KTS, PARTICULARLY
AFTER 12Z. ISOLATED SHOWERS AND STORMS, MAINLY AFTER 18Z, WITH
BRIEF/LOCAL MVFR CONDITIONS POSSIBLE, WITH CONVECTION DISSIPATING
SHORTLY AFTER 00Z. COVERAGE AND CONFIDENCE IN CONVECTION IS
LOW, AND DID NOT INCLUDE IN THE TAF AT THIS TIME.
OVERNIGHT, EXPECT LLWS TO DEVELOP ACROSS THE REGION, AND HAVE CODED
INTO THE TAF.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z TUESDAY...
FORECAST CONFIDENCE: HIGH.
ALTERNATE SCENARIOS: A SHOWER OR THUNDERSTORM COULD IMPACT THE
TERMINALS MONDAY AFTERNOON.
