DISCUSSION
KEY MESSAGE 1...
A SHORTWAVE AND STRENGTHENING LLJ WILL AFFECT THE AREA, BEFORE
DIMINISHING LATER THIS MORNING. RELATIVELY DRY AIR OBSERVED IN LOWER
LEVELS ON AREA SOUNDINGS AND SURFACE OBSERVATIONS, INDICATES
PRECIPITATION SHOULD OVERALL BE VERY LIGHT AND SPOTTY IN NATURE,
WITH MANY AREAS JUST EXPERIENCING AN INCREASE IN CLOUD COVER, OR
SPRINKLES AT BEST.
AS WE PROGRESS THROUGHOUT THE DAY TODAY, SOUTHWESTERLY FLOW WILL BE
ON THE INCREASE, WITH INCREASING WARMTH, MOISTURE AND INSTABILITY
EXPECTED. THIS WILL RESULT IN THE POSSIBILITY FOR ISOLATED SHOWERS
AND STORMS, PARTICULARLY THIS AFTERNOON AND EVENING DURING PEAK
HEATING. SEVERE IS NOT ANTICIPATED, AND ANY CONVECTION SHOULD
GENERALLY DIE OFF SHORTLY AFTER SUNSET.
TEMPERATURES WILL WARM A FEW MORE DEGREES ON TUESDAY, AS
SOUTHWESTERLY WINDS CONTINUE TO STRENGTHEN ACROSS THE AREA OUT AHEAD
OF AN APPROACHING COLD FRONT. ANOMALOUSLY HIGH MOISTURE CONTENT AIR
WILL SURGE INTO THE REGION BY TUESDAY NIGHT INTO WEDNESDAY, WITH PW
VALUES PROGGED TO TOP OUT AT AT LEAST 1.3 INCHES.
FRONTAL BOUNDARY WILL MOVE INTO THE AREA TUESDAY NIGHT THROUGH
WEDNESDAY NIGHT, WITH A LOW MOVING ALONG THE FRONT THROUGH THE AREA.
MODERATE TO HEAVY RAIN CAN BE EXPECTED DURING THIS PERIOD, WITH MOST
AREAS GENERALLY EXPECTED TO GET AT LEAST HALF AN INCH TO THREE
QUARTERS OF AN INCH THROUGH WEDNESDAY NIGHT. THIS WILL BE FOLLOWED
BY A SECONDARY WAVE ON THURSDAY, WITH AN ADDITIONAL QUARTER TO THREE
QUARTERS OF AN INCH EXPECTED, MAINLY EAST OF THE OHIO RIVER.
HOWEVER, THERE IS GREATER UNCERTAINTY DURING THIS TIME PERIOD OF HOW
MUCH RAIN WILL AFFECT THE AREA, AND WILL DEPEND ON HOW FAR SOUTH AND
EAST THE AFOREMENTIONED FRONT IS ABLE TO MAKE IT OUT OF OUR AREA.
AT THIS POINT WPC HAS PARTS OF THE AREA OUTLINED IN A MARGINAL RISK
FOR EXCESSIVE RAINFALL. THINKING OVERALL IMPACTS SHOULD BE SOMEWHAT
LIMITED, DUE TO ANTECEDENT DRY CONDITIONS, AND GREENING OF
VEGETATION ACROSS THE MAJORITY OF THE AREA.
KEY MESSAGE 2...
THE SECONDARY LOW WILL GRADUALLY EXIT OFF TO THE EAST LATER IN THE
DAY THURSDAY, WITH A BRIEF PERIOD OF DRIER CONDITIONS, AND CLEARING
TAKING HOLD FOR EARLY FRIDAY AS HIGH PRESSURE NUDGES IN FROM THE
WEST. ALTHOUGH IT WILL BE MUCH COOLER, A WIDESPREAD FROST/FREEZE IS
NOT ANTICIPATED AT THIS TIME, BUT ALSO CAN'T BE COMPLETELY RULED
OUT. WILL DEPEND ON CLEARING AND HOW QUICKLY WINDS CAN SLACKEN
ACROSS THE AREA.
AN ADDITIONAL DISTURBANCE WILL AFFECT THE AREA LATER FRIDAY INTO
SATURDAY, WITH ADDITIONAL SHOWERS.
AVIATION /06Z MONDAY THROUGH FRIDAY/
MAINLY VFR CONDITIONS EXPECTED FOR THE PERIOD. SOUTHWESTERLY WINDS,

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
