WHILE A MORE ACTIVELY 'WET' PATTERN IS EMERGING, IT WILL NOT BE
WET/RAINY THE WHOLE TIME. RATHER, WE'LL SEE IT IN SURGES, TIED
TO PERIODIC PULSES OR WAVES OF ENERGY THAT SPREAD OUT OVER A
WEEK'S TIME. STORM TOTAL AVERAGE QPF THRU MID WEEK NEXT IS 1-2",
BUT LOCALIZED HIGHER AMOUNTS MAY BE REALIZED VIA CONVECTION
AND/OR ANY REPEAT TRAINING THAT MAY OCCUR. THE NAEFS E-SAT
DEPICTS 99TH PERCENTILE 1.75"+ PW'S WITH 5-10 YR R.I'.S WITH
THE FIRST ROUND FRIDAY-FRIDAY NIGHT, SO HEAVIER RAIN POTENTIAL
EXISTS. THIS MAY ULTIMATELY LEAD TO MINOR/LOCALIZED NUISANCE
FLOODING AS IT OCCURS, WITH SOME MINOR RIVER FLOODING POTENTIAL
ESP ON OUR SMALLER STEMS; THIS LATTER PATTERN IS ALREADY
ONSETTING AND WILL BE WATCHED CLOSELY FOR EXPANSION AS THE
REAL-TIME BASIN TOTALS ARE INCORPORATED.
SATURDAY OFFERS AN IN-BETWEEN RECOVERY DAY FOR MOST AS THE
FRIDAY SURGE DEPARTS AND THE NEXT SURGE PREPS FOR SUNDAY ONSET.
THE MODELS SUGGEST THE BEST STRONG-SVR RISK REMAINS SOUTH AND/OR
EAST WITH TIME, INCLUDING FRIDAY, BUT RETURN FLOW MOISTURE/INSTABILITY
AND INCREASING BULK SHEAR WITH STRENGTHENING FLOW OVERHEAD AS
THE FIRST LOW PRESSURE WAVE(S) SURGE ACROSS SOUTHERN KY DOES
SUPPORT THE EXISTING MRGL RISK IN THE WARM SECTOR/OVER THE
PENNYRILE MAINLY EAST OF THE LAKES.
THANKS TO THE HIGH POPS DAILY, SKY COVER AND PCPN RESULTS IN
TEMPS THAT WILL SPEND MOST OF THEIR DAYTIME IN THE 70S AND
NIGHT-TIME IN THE 60S...IE MUTED...DESPITE ACTUAL HIGHS IN THE
LOWER 80S FOR MOST OF THAT TIME.
