SATELLITE ANALYSIS AND TRENDS...VIS AND IR IMAGERY DEPICT A DANGEROUS FF
SITUATION DVLPG SWWD OF THE LINE OF STRONG CELLS THAT HAS BEEN PRODUCING
DOWNPOURS ACROSS ERN OK THIS AFTERNOON. ADDTL CELLS HAVE BEGUN TO FORM
ALONG THE TAIL END OF THE LINE OF CELLS BACKBUILDING SWWD TWDS A SFC
LOW VERY NEAR K1F0 IN S CENTRAL OK JUST N OF THE TX BORDER. THIS LOW IS
AT THE POINT WHERE THE TX DRY LINE COMES VERY CLOSE TO MEETING THE FRNT
AND THE TAIL END OF THE SQUALL LINE. COLD AIR CAN BE SEEN IN IR IMAGERY
CREEPING SWD BEHIND THE FRONTAL BNDRY THROUGH OK AND WITH T DIFFERENCES
OF HIGH 60S IN CENTRAL OK COMPARED TO LOW 90S AT K1F0 AND IN N TX THE
UNSTABLE AIR MASS SHOULD CONTINUE TO PRODUCE A FEW MORE CELLS AND MAY
EVEN BECOME ANCHORED FOR A TIME INVOF MARSHALL/JOHNSTON/BRYAN/ATOKA
COUNTIES THOUGH ERLY MOVEMENT OF TROF SHOWN BY WV SHOULD FOR THE MOST
PART PREVENT THIS. THE AREA OF CONCERN IS RIGHT ON THE LEFT SIDE OF THE
NOSE OF THE THETA-E AXIS WHICH EXISTS FROM S CENTRAL TX TO S CENTRAL OK
BEFORE TURNING NEWD OUT ALONG THE LINE OF CNVTN INTO AR. ALSO LOW LVL
MOISTURE CNVG HAS INCREASED GREATLY IN THE PAST 1-2 HRS. WITH THIS AREA
ALSO BEING UNDER THE LEFT EXIT REGION OF A PASSING JET STREAK SHOWN BY
GOES STLT WINDS..SOME UPPER LVL DIFFLUENCE CAN BE EXPECTED.
.
MANUEL ESTIMATES GIVE 1-1.75" OVER BRYAN AND ATOKA COUNTIES OVER THE
PREVIOUS HR AND SIMILAR ESTIMATES OVER COAL/JOHNSTON COUNTIES FOR THAT
TIME. CELLS SHOULD CONTINUE TO REFORM/BACKBUILD FOR THE NEXT 1-2 HRS AT
LEAST PROLONGING HVY RAIN OVER THE AREA. VIS IMAGERY SHOWS THE LINE OF
CELLS BEGINNING TO BECOME W-E ORIENTED ACROSS S PITTSBURG/PUSHMATAHA
COUNTIES WITH MANY OVERSHOOTING TOPS THAT WILL PRODUCE HVY RAINS EWD
INTO WRN AR OVER THE NEXT 1-2 HRS AS WELL.
