DISCUSSION...

MILD NIGHT ACROSS THE MID STATE WITH CURRENT TEMPS IN THE UPPER
50S AND 60S WITH DEWPOINTS IN THE 50S. TODAY WILL START THE
BEGINNING OF A MUCH WARMER AND WETTER PATTERN FOR OUR REGION AS
THE PERSISTENT UPPER RIDGE OVER THE SOUTHEAST CONUS GETS FLATTENED
SOMEWHAT AND SOUTHWEST FLOW ALOFT INCREASES. LLJ PROGGED BY
GUIDANCE TO STRENGTHEN TO 30 KTS TODAY AND UP TO 45 KTS SUNDAY
NIGHT...WHICH WILL BRING MUCH DEEPER GULF MOISTURE INTO THE AREA
WITH PWATS RISING SIGNIFICANTLY INTO THE 1.25-1.75 INCH RANGE BY
THIS EVENING. AS TEMPERATURES WARM WELL INTO THE 80S
TODAY...EXPECT SOME DIURNAL ISOLATED SHOWERS AND THUNDERSTORMS TO
DEVELOP WEST OF I-65 THIS AFTERNOON AND ACROSS THE ENTIRE CWA
TONIGHT. IN ADDITION...THE STRONG LLJ WILL BRING GUSTY SOUTH WINDS
TO THE AREA TODAY INTO TONIGHT...SO BOATERS ON AREA LAKES AND
RIVERS ARE URGED TO USE CAUTION AS GUSTS WILL REACH TO AROUND 30
MPH AT TIMES.

MORE WIDESPREAD CONVECTION IS ANTICIPATED ON MONDAY AS AN
INTENSE SHORTWAVE ALOFT CREATES A LARGE AREA OF SHOWERS AND
THUNDERSTORMS TO OUR WEST WHICH GUIDANCE SPREADS ACROSS OUR NECK
OF THE WOODS DURING THE DAY. TEMPERATURES WILL LIKELY BE MUCH
COOLER THAN TODAY DUE TO CLOUDS AND PRECIP. ANOTHER INTENSE
SHORTWAVE WILL MOVE QUICKLY ACROSS THE REGION MONDAY NIGHT INTO
EARLY TUESDAY...BRINGING ANOTHER WIDESPREAD ROUND OF SHOWERS AND
STORMS. SPC HAS PLACED ALL OF MIDDLE TENNESSEE IN A SLIGHT RISK
FOR SEVERE STORMS ON TUESDAY...AND A FEW STRONG TO SEVERE STORMS
APPEAR POSSIBLE DUE TO MODERATE CAPE LEVELS AND BULK SHEAR AROUND
40 KTS. UPPER TROUGH OVER THE CENTRAL AND EASTERN CONUS WILL
WEAKEN FROM WEDNESDAY INTO NEXT WEEKEND...BUT CONTINUED
SOUTHWESTERLY FLOW ALOFT AND HIGH MOISTURE LEVELS WILL PROMPT
CHANCE TO LIKELY POPS. AFTERNOON TEMPS WILL ALSO GRADUALLY
INCREASE DUE TO LESS CLOUD COVER AND PRECIP COVERAGE. EXTENDED
RANGE MODELS SHOW A TROUGH REMAINING IN PLACE OVER THE EASTERN
CONUS AS WE MOVE INTO JUNE...SO PATTERN WILL LIKELY CONTINUE TO
BE WARM AND WET AS WE HEAD INTO CLIMATOLOGICAL SUMMER NEXT WEEK.

.OHX WATCHES/WARNINGS/ADVISORIES...
NONE.
