EVENT...SLOW SWD MOVEMENT OF W-E ORIENTED CELLS IN SE OK NEXT 1-2 HRS
.
SATELLITE ANALYSIS AND TRENDS...TWO VERY NOTICEABLE FEATURES APPEAR IN
IR IMAGERY OVER TX AND OK..ONE BEING THE RELATIVELY COLDER AIR..HIGH 50'S
TO LOW 60'S..BEHIND THE SLOWLY SAGGING COLD FRNT ACROSS OK AND THE OTHER
BEING THE DRYLINE WHICH RUNS FROM THE US BORDER AT KDLF TO K1F0/KADM IN
OK WHERE IT INTERSECTS THE COLD FRNT. ITS AT THIS POINT OVER JOHNSTON
COUNTY WHERE CELLS HAVE BEEN ANCHOR FOR THE PAST FEW HRS BUT WITH THE
COLD FRNT HAVING NOW REACHED THE AREA AND PUSHING STILL FURTHER S..THE
TAIL END OF THE SQUALL LINE WILL START TO MOVE SWD BUT AT A VERY SLOW
PACE. DRYLINE IS SEEN ADVANCING WWD IN BOTH IR AND RADAR IMAGERY SO THE
BIGGEST THREAT FOR ANCHOR CELLS APPEARS TO BE ENDING. WITH THE SQUALL
LINE ACROSS AR MOVING MORE QUICKLY TO THE E/SE NOW..THIS SHOULD BEGIN
TO PULL THE CELLS EWD AND OFF OF THE DRY LINE/COLD FRNT INTERSECTION IN
THE NEX 1-2 HRS..WHICH MAY THEN ALLOW FOR A SPEED UP IN MOVEMENT OF THE
CELLS ALONG THE RED RIVER THE ESE.
.
OOZ PW ANALYSIS INDICATED 1.25" PW VALUES STILL HELD BACK NEAR FWD
THOUGH LLJ IS NOW FOCUSING FROM CENTRAL AR NEWD INTO THE OH VLY AHEAD
OF THE SQUALL LINE PER RECENT PROFILERS. WHILE EWD MOTION OF CELLS FOR
NEXT 1-2 HRS WILL OCCUR FROM CHOCTAW COUNTY/OK EWD TWDS KM89 AND KPBF
IN AR..ESTIMATE RAINFALL AMOUNTS OF 1.5-2.5" TO OCCUR BEFORE THE CELLS
CONTINUE SEWD. SEE WEB ADDRESS IN 10-15 MIN FOR GRAPHIC ANALYSIS AND 1
HR ESTIMATE GRAPHIC ENDING 0130Z.
