...UPDATE TO AVIATION...
.UPDATE...
THROUGH 10 AM...JOPLIN HAD ALREADY REACHED 93 DEGREES F...THEREFORE
HAVE BUMPED UP HIGHS TODAY A FEW DEGREES ACROSS SOUTHEASTERN
KANSAS AND THE MISSOURI OZARKS. 12Z SGF SOUNDING HAD 850MB TEMP OF
26 DEGREES C...THIS IS 6 DEGREES HIGHER THAN YESTERDAYS SOUNDING
WHERE JOPLIN HAD A HIGH OF 101 DEGREES F. RECENT GUIDANCE IS IN
GENERAL AGREEMENT WITH MID 20S 850MB TEMPS. MIXING THESE DOWN
WILL ALLOW HIGHS TO CLIMB OVER 100 DEGREES AT NUMEROUS LOCATIONS
ACROSS THE REGION. WINDS WILL TURN TO OUT OF THE SOUTHWEST THROUGH
THE AFTERNOON DRYING OUT THE LOWER LEVELS...SUPPORTING THE VERY
HOT DRY CONDITIONS THIS AFTERNOON. A HEAT ADVISORY WILL BEGIN AT
NOON TODAY AND WILL REMAIN IN EFFECT THROUGH 7 PM TOMORROW AS HEAT
INDICES WILL BE IN EXCESS OF 105 DEGREES THIS AFTERNOON AND
TOMORROW AFTERNOON. WE WILL CONTINUE TO MONITOR CONDITIONS AS IT
IS POSSIBLE THE ADVISORY WILL NEED TO BE EXTENDED BEYOND 7 PM
TOMORROW.

.DISCUSSION...
MAIN FOCUS IN THIS FORECAST PACKAGE CONTINUES TO DEAL WITH HOT
CONDITIONS TODAY THROUGH MOST OF THE UP COMING WEEK. OVER ALL
LITTLE CHANGE TO THE GOING FORECAST.
UPPER LEVEL RIDGE OF HIGH PRESSURE IS IN PLACE ACROSS THE CENTRAL
U.S. AND WILL REMAIN CENTERED OVER THE REGION INTO TUESDAY. A SLOW
MOVING WARM FRONT IS PUSHING ACROSS THE AREA EARLY THIS MORNING AND
SHOULD MOVE TO THE NORTH OF THE AREA THIS AFTERNOON. WINDS WILL
BECOME SOUTHWESTERLY BEHIND THE FRONT AND MAY BE A LITTLE GUSTY AT
TIMES THIS AFTERNOON BEHIND THE FRONT. A VERY HOT AIRMASS IS
SPREADING INTO THE AREA WITH HIGHS EXPECTED TO WARM INTO THE
MIDDLE 90S ACROSS THE EASTERN OZARKS TO AROUND THE 100 DEGREE MARK
ACROSS SOUTHEAST KANSAS AND SOUTHWESTERN MISSOURI. DEWPOINTS WILL
BE A CHALLENGE THE NEXT FEW DAYS...AS TO JUST HOW MUCH MIXING WILL
OCCUR EACH AFTERNOON. THE BETTER MIXING POTENTIAL SHOULD OCCUR ON
MONDAY AND ESPECIALLY TUESDAY WHERE AFTERNOON DEWPOINTS MAY FALL
INTO THE MIDDLE TO EVEN LOWER 60S. WITH TEMPERATURES EXPECTED TO
WARM TO AROUND THE 100 DEGREE MARK...SOLID HEAT ADVISORY
CONDITIONS WILL OCCUR THIS AFTERNOON AND AGAIN ON MONDAY. THE
ADVISORY MAY NEED TO BE EXTENDED INTO TUESDAY...BUT WITH MORE
QUESTIONS WITH DEWPOINTS DUE TO MIXING AND THE POSSIBILITY OF
INCREASED CLOUD COVER FROM AN APPROACHING TROPICAL WAVE...DECIDED
NOT TO EXTEND THE HEAT ADVISORY INTO TUESDAY WITH THIS PACKAGE.
AS MENTIONED ABOVE A TROPICAL WAVE THAT PUSHED INTO TEXAS
OVERNIGHT...IS EXPECTED TO UNDERCUT THE UPPER LEVEL RIDGE AND
MOVE ACROSS THE REGION BY WEDNESDAY. THIS WAVE SHOULD BRING A SLUG
OF MOISTURE AND INCREASED LIFT TO THE AREA. ALSO...IT SHOULD HELP
TO WEAKEN THE CAP SOME. WITH THAT SAID THERE WILL BE THE POTENTIAL
FOR THUNDERSTORMS MAINLY DURING THE AFTERNOON AND EARLY EVENING
HOURS WHEN INSTABILITY WILL BE INCREASED DUE TO THE HEATING OF THE
DAY. THINK THIS ACTIVITY WILL REMAIN MORE ON THE ISOLATED TO
SCATTERED NATURE. THIS WAVE WILL SLOWLY MEANDER ACROSS THE CENTRAL
U.S. AND COULD RESULT IN THUNDERSTORM POTENTIAL ACROSS THE AREA INTO
FRIDAY.
BY NEXT WEEKEND THE UPPER LEVEL RIDGE BUILDS RIGHT BACK OVER THE
AREA...WITH A RETURN TO TEMPERATURES IN THE UPPER 90S TO AROUND
100 DEGREES EXPECTED.

SLIGHTLY THROUGH THE EVENING INTO TOMORROW.
