...UPDATE TO AVIATION...

.UPDATE...

SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ARE DEVELOPING
ACROSS EASTERN KANSAS INTO NORTHEASTERN OKLAHOMA THIS MORNING.
THIS ACTIVITY IS DEVELOPING IN AN AREA OF MOISTURE TRANSPORT AND
THETA-E ADVECTION. IN ADDITIONAL A WEAK UPPER LEVEL DISTURBANCE
IS ALSO SPREADING EAST ACROSS THE CENTRAL PLAINS. ELEVATED
INSTABILITY IS ALSO SPREADING NORTH INTO THE AREA WITH THIS
ACTIVITY. THESE FEATURES WILL CONTINUE TO SPREAD TO THE NORTH AND
EAST ACROSS THE REGION THIS AFTERNOON. SCATTERED SHOWERS WITH
ISOLATED TO SCATTERED THUNDERSTORMS WILL SPREAD TO THE EAST
NORTHEAST ACROSS THE AREA...WITH THE BEST COVERAGE GENERALLY
EXPECTED ACROSS EXTREME SOUTHEAST KANSAS AND THE WESTERN MISSOURI
OZARKS INTO CENTRAL MISSOURI. SMALL HAIL MAY BE POSSIBLE WITH THE
STRONGER STORMS ACROSS THE WESTERN PORTIONS OF THE FORECAST AREA.
HAVE INCREASED POPS FOR TODAY BASED ON THESE TRENDS. UPDATED
PRODUCTS HAVE BEEN SENT.

.DISCUSSION...

A COOL START THIS MORNING WITH READINGS IN THE LOWER 50S AND UPPER
40S. THE COOLER READINGS ARE AT THE LOCATIONS THAT HAVE CLEARER
SKIES AND LIGHTER WINDS THIS MORNING.

WE WILL SEE SOME QUICK CHANGES IN THE WEATHER LATER TODAY. A
RAPID RETURN OF WARMTH AND MOISTURE WILL HAPPEN OVER THE NEXT 24
HOURS. A SURFACE LOW WILL DEVELOP IN NORTHWEST TEXAS AND A STRONG
LOW LEVEL JET WILL SURGE MOISTURE NORTHWARD LATER TODAY AND
TONIGHT. A SURFACE WARM FRONT WILL ALSO BEGIN TO ADVANCE NORTHWARD
TOWARDS THE OZARKS LATE TODAY.

A STRONG CAP THIS AFTERNOON WILL KEEP THE DEVELOPMENT TO A
MINIMAL ACROSS OUR AREA...BUT EXPECTING SOME SHOWERS AND STORMS
MOVING INTO THE AREA LATE THIS EVENING AND OVERNIGHT. DECENT
ISENTROPIC LIFT WITH LOW LEVEL MOISTURE STEADILY INCREASING WILL
HELP DEVELOP STRONG TO ISOLATED SEVERE STORMS POSSIBLE TONIGHT. A
DIFLUENT MID AND UPPER LEVEL JET WITH FORECAST SOUNDINGS SHOW
MLCAPE FROM 1000 TO 2000 J/KG...A STRENGTHENING LOW LEVEL JET
TONIGHT WITH 50 TO 60 EFFECTIVE SHEAR POSSIBLE WHICH WILL SUPPORT
THE CHANCE FOR A FEW STORMS WITH LARGE HAIL WHICH WILL BE THE MAIN
THREAT.

MOST OF THE ACTIVITY WILL BE MOVING INTO CENTRAL AND NORTHERN
MISSOURI BY LATE SATURDAY MORNING. WARMER AND MORE HUMID
CONDITIONS WILL MOVE IN FOR THE WEEKEND. THE FRONTAL BOUNDARY WILL
BE NORTH OF OUR REGION AND A SURFACE HIGH TO AND MID LEVEL HIGH
PRESSURE WILL BUILD IN FOR THE LATTER PART OF THE WEEKEND. THE
WEATHER PATTERN LOOKS PRETTY QUIET AND ALMOST SUMMER LIKE WITH A
RIDGE OF HIGH PRESSURE JUST TO OUR EAST WITH STORM SYSTEMS MOVING
OUT OF THE ROCKIES UP TO THE NORTHERN PLAINS. OCCASIONAL PRESSURE
GRADIENTS WILL KEEP SOUTHERLY WINDS ON THE BREEZY SIDE FROM TIME
TO TIME. TEMPERATURES WILL BE IN THE MID AND UPPER 80S IN THE
AFTERNOONS AND IN THE MID 60S AT NIGHT.

A SAGGING FRONTAL BOUNDARY MAY TRY TO SLIP DOWN DURING THE MIDDLE
PART OF NEXT WEEK TO GIVE SLIGHT CHANCE FOR POPS BUT KEEPING THE
FORECAST MAINLY DRY AND VERY WARM NEXT WEEK. LOOKING AT A MID
LEVEL RIDGE OF HIGH PRESSURE REALLY SETTING UP ACROSS THE CENTRAL
AND SOUTHERN PLAINS REGION BY THE END OF NEXT WEEK WHICH WILL MAKE
FOR MORE DRY AND WARM CONDITIONS.

.AVIATION...

CURRENTLY AN ELEVATED LINE OF CONVECTION HAS DEVELOPED ALONG A
DISTURBANCE ACROSS EASTERN KANSAS AND WESTERN MISSOURI. AS THIS
CONVECTION LIFTS NORTH NORTHEAST ACROSS SOUTHWEST MISSOURI IT WILL
IMPACT ALL THREE TAF SITES THIS AFTERNOON. EXPECTING A LULL IN
CONVECTION ONCE THIS LINE MOVES THROUGH LATE IN THE AFTERNOON AND
EARLY EVENING BEFORE A WARM FRONT LIFTS NORTH ACROSS THE MISSOURI
ARKANSAS BORDER AND ONCE AGAIN BRINGS SHOWERS AND THUNDERSTORMS
ACROSS THE REGION IMPACTING ALL THREE SITES AGAIN. PINPOINTING THE
EXACT TIMING AND LOCATION OF STORMS WILL BE NEXT TO
IMPOSSIBLE...THEREFORE HAVE MENTION OF VCTS AND VCSH THROUGH THE
OVERNIGHT AND EARLY SATURDAY MORNING. EXPECTING VFR CEILINGS AND
VISIBILITIES TO PREVAIL THROUGH MOST OF THE TAF PERIOD...HOWEVER
AN MVFR STRATUS DECK CONTINUES TO HOVER OVER BBG...AND IS EXPECTED
TO PREVAIL THROUGH MOST OF THE AFTERNOON. COULD SEE MVFR OR IFR
CONDITIONS IF ANY SITE IS DIRECTLY IMPACTED BY A THUNDERSTORM.
