DAY 3 CONVECTIVE OUTLOOK...REF AWIPS GRAPHIC PGWK48 KWNS.
VALID 141200-151200
LESS THAN A SLIGHT RISK.
BROAD TROUGH OVER THE NRN PACIFIC WILL CONTINUE TO SEND SEVERAL
MINOR SHORTWAVE TROUGHS INTO THE NRN CA/SRN ORE COASTAL AREA DURING
THE PERIOD. PATTERN OVER MUCH OF THE CENTRAL U.S. INTO THE GREAT
LAKES BECOMES ZONAL BEHIND MINOR SHORTWAVE RIDGE OVER THE OHIO
VALLEY.
MOST NOTABLE FEATURE ON THE DAY 3 FORECAST IS THE CONTINUED LOW
LEVEL WARM ADVECTION FROM THE SRN PLAINS INTO THE LOWER MO AND MID
MS VALLEY AREAS. SURFACE LOW IS FORECAST TO DEVELOP OVER ERN
NEB/WRN IA AFTER 15/00Z ENHANCED BY 40-50 KT LOW LEVEL JET FROM
NWRN TX INTO W CENTRAL IL. MODELS DEPICT THETA-E AT 850 MB OF 320K
WITH INSTABILITY OF 2000 TO 2500 J/KG. REVIEW OF MODEL FORECAST
SOUNDINGS SHOW RELATIVELY STEEP LAPSE RATES OF 7.5C/KM...ALL
INDICATORS TOWARDS POSSIBLE HAIL IF THUNDERSTORMS DEVELOP. MID
LEVEL FLOW/FORCING SEEMS WEAK ATTM...BUT HAVE INCLUDED A LOW
PROBABILITY FOR HAIL.

AREAS AFFECTED...SERN LA...SRN MS...SRN AL...WRN FL PANHANDLE
CONCERNING...SEVERE THUNDERSTORM POTENTIAL
VALID 121611Z - 121915Z
THUNDERSTORMS ARE EXPECTED TO INCREASE IN COVERAGE THROUGH EARLY
AFTERNOON. A FEW STORMS COULD CONTAIN SEVERE HAIL.
LATEST RADAR TRENDS SHOW STORMS INCREASING OVER SRN MS AND
AL...ATOP A STABLE LAYER. STORMS ARE BEING FED FROM THE SW WHERE
MUCAPES ARE ON THE ORDER OF 1000-1500 J/KG. WEAK DISTURBANCES
ALOFT WILL HELP SUPPORT THUNDERSTORM DEVELOPMENT THROUGH THE
EARLY AFTERNOON HOURS. STEEP LAPSE RATES ABOVE 700 MB WILL ALLOW
THE MOST PERSISTENT STORMS TO DEVELOP HAIL. DAMAGING WINDS
APPEAR TO BE LESS LIKELY GIVEN WEAK MEAN WINDS THROUGH THE MID
TROPOSPHERE...SLOW STORM MOTIONS...AND COOL BOUNDARY LAYER.
HIGHEST RELATIVE WIND THREAT WILL BE OVER SERN LA...WHERE WARMER

A PROGRESSIVE PATTERN OVER THE US WILL REMAIN IN PLACE THROUGH THE
PERIOD AS AN UPPER-LEVEL TROUGH MOVES ACROSS THE APPALACHIANS.
ANOTHER TROUGH WILL APPROACH THE W COAST. A BROAD RIDGE ALOFT WILL
DOMINATE THE PLAINS AS A DIFFUSE SHORT-WAVE TROUGH MOVES SEWD

WILL BE PLENTIFUL IN ADVANCE OF THE UPPER-TROUGH WITH CONVECTION
LIKELY DEVELOPING ALONG AND AHEAD OF THE FRONT. ALTHOUGH
UNIDIRECTIONAL FLOW IS EXPECTED...0-6 KM SHEAR OF 35-40 KTS SHOULD
BE FAVORABLE FOR ORGANIZED LINEAR CONVECTION. VEERED WINDS AT THE
SURFACE AND FORECAST MLCAPE OF 500-1000 J/KG SHOULD LIMIT
CONVECTION UPDRAFT STRENGTH. HOWEVER...500 MB TEMPS OF -16C AND
LAPSE RATES AROUND 6.5 C/KM MAY SUPPORT SMALL HAIL.

UPPER TROUGH ANALYZED FROM TN TO SERN TX WILL LIKELY AID THE
DEVELOPMENT OF WIDESPREAD CONVECTION IN THIS REGION. HOWEVER...
VEERED WINDS AT THE SURFACE IN THE WARM SECTOR AND WEAK DEEP LAYER
SHEAR SHOULD KEEP CONVECTION BELOW SEVERE LIMITS.

MO. THE DRYLINE CONTINUES TO SHARPEN FROM THE LOW SWWD THROUGH
WRN OK INTO SWRN TX. SURFACE DEWPOINTS IN THE UPPER 50S TO LOWER

CONCERNING...SEVERE THUNDERSTORM POTENTIAL
VALID 121936Z - 122230Z
THUNDERSTORMS ARE EXPECTED TO CONTINUE THROUGH THE AFTERNOON

ELY LOW LEVEL WINDS OFF THE GULF STREAM COMBINED WITH INCREASING
WESTERLIES ALOFT WILL MAKE FOR STRAIGHT LINE HODOGRAPHS WITH

SOUNDINGS SHOW MLCAPES OF 1500-2000 J/KG WITH COLD TEMPERATURES
AT MID LEVELS SUGGESTING HAIL WILL BE POSSIBLE WITH THE STRONGEST
AND LONGEST LIVED STORMS. ALTHOUGH SHALLOW LOW LEVEL CONVERGENCE
AND POOR LOW LEVEL LAPSE RATES WILL PRECLUDE EXPLOSIVE
DEVELOPMENT...HINTS OF UPWARD VERTICAL MOTION IN UPPER LEVELS
OVER THE NRN GULF AND DEPICTED IN MODEL FIELDS MAY BOOST
CONVECTIVE DEVELOPMENT THROUGH THE AFTERNOON.

AREAS AFFECTED...SRN AR AND NRN LA
CONCERNING...SEVERE THUNDERSTORM POTENTIAL
VALID 122008Z - 122245Z
ISOLATED LARGE HAIL WILL REMAIN POSSIBLE OVER SRN AR AND NRN LA
THROUGH THE REMAINDER OF THE AFTERNOON. DUE TO THE EXPECTED
LIMITED AREAL COVERAGE A WW IS NOT ANTICIPATED.
LATEST REGIONAL RADAR DATA SHOW TSTMS INCREASING IN COVERAGE AND
INTENSITY FROM SWRN AR INTO NRN MO. GIVEN THE RELATIVELY LOW
SURFACE THETA-E AIR IN PLACE OVER THE AREA...IT APPEARS THESE
TSTMS ARE LIKELY ELEVATED AND OCCURRING ON THE NOSE OF 850 MB
MOISTURE ADVECTION WHERE MUCAPES HAVE INCREASED TO 1000-1500
J/KG.
ADDITIONAL TSTM DEVELOPMENT REMAINS POSSIBLE E OF THE CURRENT
ACTIVITY AS FORCING FOR LARGE SCALE ASCENT INCREASES AHEAD OF
WEAK MID-LEVEL SHORTWAVE CURRENTLY OVER NRN TX.
CURRENT VWP/WIND PROFILER DATA SHOW MARGINALLY STRONG DEEP-LAYER
SHEAR FOR ORGANIZED CONVECTION WITH ISOLATED LARGE HAIL BEING THE
PRIMARY THREAT. TSTMS WILL LIKELY BEGIN TO DIMINISH IN INTENSITY
LATE THIS AFTERNOON/EARLY EVENING AS THEY MOVE E OF THE ELEVATED
INSTABILITY AXIS.

It looks like we could see some really big hail in Kansas and Missouri this evening, as well as parts of Oklahoma. The sun has been out warming and destablizing the atmosphere. Dewpoint is up to 57.
Dewpoint in Chanute is 60. Tulsa's is 61.
Waiting now for the storms to fire...
