A SHORTWAVE TROUGH ACROSS THE MIDWEST WILL SLIDE EASTWARD INTO THE
OHIO VALLEY ON TUESDAY. THIS WILL ALLOW A COLD FRONT TO SINK
SOUTHEAST ACROSS OUR REGION TONIGHT. FORCING ALONG AND AHEAD OF THE
BOUNDARY WILL KICK OFF SHOWERS AND STORMS. WHILE SOME ISOLATED
ACTIVITY IS POSSIBLE THIS AFTERNOON, IT APPEARS COVERAGE WILL BE
HIGHER THIS EVENING INTO THE EARLY OVERNIGHT PERIOD, BEFORE
DWINDLING HEADING INTO EARLY TUESDAY MORNING. 0-6KM SHEAR IS QUITE
LIMITED, MAYBE UP TO 25 KTS. PWS ARE HIGH, RANGING FROM 2-2.2"
THOUGH. INSTABILITY WILL ALSO BE DECENT, WITH MLCAPE ABOVE 2000
J/KG. THUS, CAN'T RULE OUT SOME STRONGER DOWNDRAFTS GENERATING SOME
SEVERE WINDS WITH A STORM OR TWO. A LOCALIZED FLASH FLOODING THREAT
IS ALSO PRESENT. ANY SORT OF TRAINING OF CONVECTION COULD GENERATE
SOME NARROW SWATHS UP TO OR POSSIBLY EXCEEDING 2". LOW LEVEL
MOISTURE LINGERS ON TUESDAY, WHICH MAY ALLOW SOME ISOLATED SHOWERS
OR STORMS TO CONTINUE ACROSS WEST KENTUCKY THROUGH AT LEAST THE
FIRST HALF OF THE DAY.
SURFACE HIGH PRESSURE WILL MAINTAIN AN EXTENDED PERIOD OF DRY
WEATHER WEDNESDAY THROUGH SATURDAY. DEW POINTS, WHICH HAVE BEEN
CONSISTENTLY IN THE MID TO UPPER 70S FOR 10 DAYS NOW, WILL FINALLY
TREND DOWN INTO THE MID TO UPPER 60S ON WEDNESDAY AND THURSDAY.
WINDS TURN BACK AROUND TO SOUTHERLY BY FRIDAY INTO NEXT WEEKEND
THOUGH, WHICH WILL ALLOW DEW POINTS TO SNEAK BACK ABOVE 70 (AND
POSSIBLY MID 70S AGAIN BY SUNDAY).
UPPER LEVEL RIDGING BUILDS BACK INTO THE REGION IN TIME FOR
INDEPENDENCE DAY. AS 850MB TEMPS RISE FROM 15-16C TO AROUND 19-20C
FOR THE WEEKEND, HIGHS WILL NUDGE BACK ABOVE 90. HEAT INDEX READINGS
IN THE MID TO UPPER 90S ON FRIDAY WILL TREND CLOSER TO OR JUST ABOVE
100 OVER THE WEEKEND. WHILE MOST OF THE HOLIDAY WEEKEND LOOKS DRY,
THERE ARE SOME INDICATIONS OF HEIGHT FALLS ON SUNDAY AS TROUGHING
LIFTS FROM THE PLAINS INTO THE UPPER MIDWEST. THIS MAY LEAD TO SOME
CONVECTION SNEAKING SOUTH INTO OUR AREA.
