A SMALL SECONDARY TSTORM CLUSTER SHIFTING SE ACROSS EC MS AT THIS
TIME. THIS CLUSTER HAS SHOWN AN OVERALL WEAKENING TREND OVER THE PAST
HALF HOUR.

LATEST VIS SHOWS MORNING MID/HIGH CLOUDS LOSING OPACITY AND SHIFTING
EAST ALLOWING FOR INSOLATION TO RESUME ACROSS THE DELTA REGION. THIS

LATE MORNING HOURS. AGITATED CUMULUS FIELD AND INCREASING ALTO DECK
HAS BUILT ALONG AND AHEAD OF THE SFC FRONT IN N-CNTRL AR AS S/WV
SHEAR AXIS AIDS IN BETTER DEEP-LYR LIFT. EXPECT THIS AREA TO BE THE

DELTA AND NRN AREAS THIS AFTN AS MODIFIED KJAN SOUNDING INDICATES
~2200 SBCAPE WITH FAVORABLE LAPSE RATES WITH ENOUGH SUPPORTIVE SHEAR
TO AID IN STORM ORGANIZATION. EXPECT SHOWERS/TSTORMS TO BECOME
SCATTERED TO NUMEROUS THIS AFTN ACROSS NRN/CNTRL AREAS WITH SOME
POSSIBLY BECOMING STRONG TO SEVERE AS THEY CONTINUE TO SHIFT SOUTH.
MAIN RISKS CONTINUE TO BE WIND GUSTS TO 60 MPH AND QUARTER SIZED HAIL
IN THE STRONGEST OF STORMS FROM 1PM-8PM.

CONCERNING OTHER FORECAST ELEMENTS...HOURLY TEMPS WERE ADJUSTED TO
ACCOUNT FOR LATEST TRENDS WITH THE SE WARMING QUICKLY DUE TO NO CLOUD
COVER AND GTR BEING THE SLOWEST. MAX TEMPS WERE REDUCED A DEGREE OR
SO GIVEN LATEST TRENDS. POPS WERE REDUCED ACROSS CNTRL/SRN ZONES
THROUGH NOON WITH INCREASING CHANCES THROUGH THE 1-8PM WINDOW.
RAIN CHANCES WILL DECREASE BUT LINGER THROUGH THE OVERNIGHT AS FRONT
SLOWLY SLIDES SOUTH THROUGH THE REGION. /ALLEN/
