SURFACE MAP AT 07Z SHOWS RIDGE OF HIGH PRESSURE
MOVING NEAR MIDDLE TENNESSEE, WITH RETURN FLOW ABOUT 24 HOURS
AWAY. SKIES ARE CLEAR THIS HOUR, WITH DEW POINTS IN THE 50'S
ACROSS THE NORTH, IN THE 60'S ACROSS THE SOUTH, AND MILD
TEMPERATURES RESULTING FROM THE NORTHERLY FLOW AND DRY AIR.
ATMOSPHERIC MODELS GIVE US ANOTHER DAY OF PLEASANT WEATHER BEFORE
THE NEXT WEATHER SYSTEM BRINGS CONVECTION TO THE MID STATE. BY
FRIDAY, A WEAK SHORTWAVE WILL PRODUCE SCATTERED CONVECTION ACROSS
THE MID STATE, AND BY THEN WARMER SURFACE TEMPERATURES WILL HELP
CONTRIBUTE TO INCREASED INSTABILITY.
THE RAIN CHANCE WILL CONTINUE THROUGH THE WEEKEND AS THE 500 MB
HEIGHT PATTERN AMPLIFIES AS A SHORTWAVE DEVELOPS TO OUR EAST,
STRENGTHENING THE NORTHWEST FLOW ALOFT AND FURTHER DESTABILIZING
THE ATMOSPHERE.
AS TEMPERATURES WARM BACK INTO THE LOWER AND MID 90'S, LOOK FOR
THE BERMUDA HIGH TO RE-ESTABLISH ITSELF, MEANING THE
CHARACTERISTIC HOT, HUMID AIR MASS WILL SETTLE OVER THE MID STATE,
MEANING THAT ISOLATED CONVECTION WILL BE PART OF THE FORECAST
THROUGH THE END OF THE 7-DAY CYCLE.
