UPPER LEVEL RIDGING WILL BECOME SUPPRESSED TODAY, REPLACED BY
TROUGHING ACROSS THE NORTHERN TIER OF THE COUNTRY. INCREASED
RETURN FLOW AND PERSISTENT GULF MOISTURE UNLEASHED NORTHWARD,
WILL BRING RAIN CHANCES BACK TO WESTERN AND MIDDLE TN TODAY. IT'S
POSSIBLE A STRAY SHOWER OR SPRINKLE, MUCH LIKE YESTERDAY FOR
SOME, COULD OCCUR THIS AFTERNOON. FOR MOST, IT WILL BE ANOTHER DRY
DAY WITH INCREASING CLOUDS, HUMIDITY, AND CONTINUED WARMTH.
THE APPROACHING LOWERING HEIGHTS ALOFT WILL BRING A WELCOMED COLD
FRONT TO THE REGION TUESDAY INTO WEDNESDAY. ONE MORE DAY OF HIGHS
IN THE 80S UNTIL THE REST OF THE FORECAST READS IN THE 70S,
ESPECIALLY IN THE VALLEY. RAINFALL AMOUNTS WILL BE GREATEST
CLOSEST TO KENTUCKY AND WEST VIRGINIA. QPF TOTALS DROP CLOSER TO
THE SOUTHERN APPALACHIANS AND SOUTHEAST TN. IT'S POSSIBLE OVER AN

FOLLOWING THE FROPA, THURSDAY AND FRIDAY, ADDITIONAL SHORTWAVES

MAY BE A FEW SPRINKLES/LIGHT SHOWERS AROUND ESPECIALLY CHA, BUT
THESE ARE NOT EXPECTED TO BE IMPACTFUL. THERE IS A LOW CHANCE OF
MVFR CIGS MOVING INTO CHA FOR A FEW HOURS EARLY AND THEN AGAIN
LATE IN THE PERIOD, BUT RIGHT NOW THE PROBABILITY LOOKS TOO LOW TO
WARRANT INCLUSION. WILL GO WITH A VFR FORECAST ALL SITES FOR THE
PERIOD.
