[venture]

At 9:32 PM, Tipton [Tillman Co, OK] AMATEUR RADIO reports TSTM WND GST of E76 MPH

[venture]

Radar Update for the west metro...

Normalized Rotation is the image on the right, which is good in identifying high wind areas on setups like this. Also on the left look for curls in the line to pick up areas where a quick spin up could occur.

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
528...529...530...CONTINUES.

SUMMARY...THE THREAT FOR 50-70 MPH WIND GUSTS WILL PROBABLY INCREASE
AND BECOME WIDESPREAD ACROSS PORTIONS OF SWRN AND INTO CNTRL OK
DURING THE NEXT FEW HOURS AS A CONVECTIVE LINE TRACKS EWD THROUGH
THE REGION.

DISCUSSION...RADAR MOSAIC IMAGERY DURING THE PAST 30-60 MINUTES HAS
SHOWN A FAIRLY RAPID INTENSIFICATION IN CONVECTIVE INTENSITY AS
SHOWN IN THE OVERALL DEEPENING OF REFLECTIVITY STRUCTURE IN HEIGHT
AND MAGNITUDE. RAPID NWD TRANSPORT OF LOW-LEVEL MOISTURE IS
UNDERWAY ACROSS N-CNTRL TX INTO OK WITH AN AXIS OF LOWER 60S
DEWPOINTS E OF THE QLCS FROM THE RED RIVER NWD TO I-40. 02Z
SUBJECTIVE SURFACE MESOANALYSIS PLACES THE COLD FRONT APPROXIMATELY
25 MI TO THE W OF THE LEADING EDGE OF THE QLCS GUST FRONT. AN
INVERTED TROUGH EVIDENT BY A SURFACE WIND SHIFT APPEARS TO LARGELY
BE PARALLELING THE I-44 CORRIDOR FROM NEAR OKC NEWD TO TUL.

AS THE INTENSE MID-LEVEL SHORTWAVE TROUGH/SPEED MAX APPROACHES THE
SRN PLAINS...FORCING FOR ASCENT WILL MAXIMIZE TONIGHT COINCIDENT
WITH THE FRONTAL FORCING EVENTUALLY REACHING THE W EDGE OF THE WARM
SECTOR OVER THE NEXT FEW HOURS. AS A RESULT...THE SQUALL LINE WILL
LIKELY STRENGTHEN AND THE PROPENSITY FOR SEVERE WIND GUSTS WILL BE
MAINTAINED OR INCREASE...ESPECIALLY INVOF ANY DEEPER CORES OR WITH
MESOVORTICES THAT DEVELOP AS THE LINE MATURES NEAR AND S OF THE
INVERTED TROUGH OVER CNTRL OK.

FARTHER S OVER WRN N-CNTRL TX...EXPECTING THE GRADUAL ZIPPERING SWD
OF THE QLCS WITH STRONG TO SEVERE WIND GUSTS BECOMING THE
PREDOMINATE THREAT WITH THIS ACTIVITY. HOWEVER...THE STRONG SLY
LOW-LEVEL JET AND ISENTROPIC ASCENT WILL AT LEAST SUPPORT THE NOTION
FOR STORMS TO DEVELOP AHEAD OF THE LINE AND POSE PRIMARILY A LARGE
HAIL THREAT WITH THE MORE INTENSE STORMS.

THE SEVERE THREAT APPEARS TO BE LESS OVER NRN OK AND SRN KS DUE IN
PART TO ONLY LOWER-MID 50S DEWPOINTS AND A LESS UNSTABLE AIRMASS
RESIDING IN THIS REGION. PERHAPS A FEW STRONG TO SEVERE STORMS MAY
POSE A MARGINAL LARGE HAIL THREAT THE NEXT FEW HOURS.
