DISCUSSION

***********TODAY'S SEVERE POTENTIAL*************************
SINCE THE LAST DISCUSSION, SPC HAS EXPANDED THE MARGINAL RISK TO THE
REMAINDER OF THE S IN CWA COUNTIES, WITH A SLIGHT JUST CLIPPING
WASHINGTON, ORANGE, DUBOIS, AND SCOTT COUNTIES. WHILE THE UPPER-
LEVEL WIND PROFILE AND SHEAR IS FAVORABLE FOR A WIND AND LOW-END
TORNADO THREAT, THIS RISK IS ENTIRELY BASED ON THE POTENTIAL OF
STORMS TO FORM. AT THE MOMENT, IT DOES NOT APPEAR THAT WE HAVE HAD
OR WILL HAVE ENOUGH SURFACE HEATING FOR THESE STORMS TO FORM.
HOWEVER, IF CLEARING OCCURS ACROSS SOUTHERN ILLINOIS AND INDIANA
WITHIN THE NEXT TWO HOURS, THIS THREAT MAY BECOME SLIGHTLY MORE
REALISTIC. THIS THREAT SHOULD QUICKLY CLEAR OUT AFTER SUNSET AS WE
LOSE THE SURFACE-BASED ENERGY TO SUSTAIN IT.
***********OVERNIGHT AND FRIDAY'S COLD FRONT*******************
BOWLING GREEN HAS BROKEN THEIR HIGH RECORD FOR TODAY, ALTHOUGH THEY
ARE LIKELY THE ONLY ONES. CLOUD COVER HAS KEPT THE REST OF THE CWA
IN A FOG/DRIZZLE/SHOWERY ENVIRONMENT TODAY, PUSHING THE HIGH TEMPS
TOWARD THE LOW 80S INSTEAD. OVERNIGHT, OUR MINIMUM TEMPERATURES WILL
OCCUR CLOSE TO SUNRISE. THERE SHOULD BE A NORTHWEST TO SOUTHEAST
GRADIENT, WITH TEMPERATURES IN SOUTHERN IN IN THE MID-50S AND SOUTH
CENTRAL KY IN THE MID-60S. WE EXPECT THE COLD FRONT TO PUSH THROUGH
IN THE SAME DIRECTION, WITH IT PASSING OVER S IN AROUND 08Z. THIS
MEANS THAT TOMORROW'S MAX TEMPS SHOULD ALSO OCCUR JUST AFTER
SUNRISE, WITH HIGHS NEAR 60 FOR S IN, THE BOWLING GREEN AREA, AND
THE LOUISVILLE AREA. HIGHS ARE LIKELY TO BE CLOSER TO THE UPPER 60S
FOR THE BLUEGRASS AND LOW 70S FOR LAKE CUMBERLAND AREA.
WITH THIS COLD FRONT, EXPECT TO SEE A WIND SWITCH FROM SOUTHWESTERLY
FLOW TO NORTHWESTERLY FLOW. IT WILL BE BREEZY TOMORROW, WITH
SUSTAINED SPEEDS IN THE 13-15 KT RANGE AND GUSTS UP TO 25KTS. WINDS
WILL PERSIST INTO THE OVERNIGHT HOURS. A LIGHT LINE OF SHOWERS IS
ALSO LIKELY, WHICH SHOULD CLEAR OUT BY TOMORROW EVENING. TOMORROW
NIGHT'S MIN TEMPERATURES WILL BE AROUND THE 40 DEGREE MARK.
**************THIS WEEKEND'S FALL WEATHER**********************
SATURDAY SHOULD SEE SOME SEASONABLE TEMPERATURES, WITH HIGH
TEMPERATURES IN THE 50S. BREEZY CONDITIONS SHOULD PERSIST THROUGH
THE DAY ON SATURDAY, WITH WIND DIRECTION SHIFTING TO NORTHEASTERLY
THROUGHOUT THE DAY AS AS THE SURFACE LOW PUSHES OFF THE COAST AND A
SURFACE HIGH SETS UP OVER NORTHERN INDIANA. OVERNIGHT SATURDAY
NIGHT, WINDS SHOULD SLOW DOWN. FROST IS CERTAINLY NOT OUT OF THE
QUESTION EARLY SUNDAY MORNING, BUT WINDS ARE THE LIMITING FACTORS.
TEMPERATURES WILL BE IN THE LOW TO MID-30S ACROSS THE REGION FOR
OVERNIGHT LOWS. WE DO WARM BACK UP A BIT ON SUNDAY, WITH HIGHS IN
THE MID-60S AS THE HIGH PRESSURE PUSHES TOWARDS PENNYSYLVANIA, WHERE
IT STAGNATES OVER THE MID-APPALACHIANS. THIS WILL LEAD TO A
CONTINUES WIND SHIFT, TO THE POINT WHERE WE LIKELY HAVE SOUTHERLY
FLOW SUNDAY EVENING, ALBEIT LIGHT FLOW. EXPECT CHLLY OVERNIGHT LOWS
AGAIN, IN THE 30S.
THE STAGNANT HIGH PRESSURE SHOULD KEEP US SEASONABLE FOR THE END OF
NEXT WEEK, WITH HIGHS IN THE 70S AND LOWS IN THE 40S. EXPECT MOSTLY
LIGHT WINDS THROUGHOUT. HOWEVER, CLEAR SKIES SHOULD BE VISIBLE FOR
SOME GORGEOUS FALL SUNSETS.

A STATIONARY FRONT IS CURRENTLY DRAPED OVER NORTHERN KY
LEADING TO MORE CLOUD COVER ON THE COOL SIDE TO THE NORTH. OVERCAST

SOUTH TO NORTH. SCATTERED TO ISOLATED RAIN SHOWERS (AND A FEW
STORMS) WILL REMAIN IN THE TAFS FOR TONIGHT AND INTO TOMORROW. SITES

OVERNIGHT AHEAD OF A COLD FRONT MOVING IN FROM THE NW. AS THE
BOUNDARY PUSHES INTO THE FORECAST AREA OVERNIGHT TONIGHT INTO
TOMORROW MORNING, A WIND SHIFT WITH 20-25KT WINDS ARE EXPECTED FOR
ALL SITES. THERE IS A 40-50% CHANCE THAT WIND GUST COULD OVERACHIEVE
>25KTS. WITH AMPLE MOISTURE AHEAD OF THE FRONT, RAIN SHOWERS HAVE TO
POTENTIAL TO FORM IN THE MORNING WITH THE FORCING OF THE BOUNDARY.
