SATELLITE ANALYSIS AND TRENDS...ANOMALOUS UL TROF/RIDGE COUPLET HAS SET
THE STAGE FOR CONTINUED DEEP MOISTURE TRANSPORT FROM SUBTROPICAL EAST
PAC. PW VALUES ARE GENERALLY 2 STD DEV ABOVE NORMAL ACROSS NERN TX/NWRN
LA/AR. BROAD ISENTROPIC ASCENT ACROSS THE REGION IS CURRENTLY ENHANCED
BY RIGHT ENTRANCE REGION JET DYNAMICS OVER THE ARKLATEX AREA AS WELL AS
A LOWER LEVEL CONVERGENT BNDRY IDENTIFIED BY VWP DATA AT 850 MB ALONG
THE TX/OK BORDER AND INTO SRN AR. THIS ENHANCEMENT HAS BEEN SEEN IN BOTH
IR/WV IMAGERY AS WELL AS MOD/HVY RAINFALL IN NERN TX.
.
THE PRIMARY CONCERN OVER THE NEXT FEW HRS INTO THE EVENING WILL BE
THE CHANGE-OVER FROM RAIN TO FRZ RAIN TO SNOW FROM NW TO SE ACROSS SRN
OK/NERN TX/AR. THE COLD FRONT HAS ALREADY PASSED THRU AND MADE IT INTO
CNTL TX. THE FRZ LINE APPEARS TO BE CURRENTLY SET UP ACROSS NRN TX/SRN
OK/NRN AR AND STRONG CAA ASSOCIATED WITH 25 KT NORTHERLY SFC WINDS
CONTINUE TO PUSH THE FRZ LINE FURTHER S/SE. LATEST NESDIS SNOWFALL RATE
PRODUCT FROM 1857Z INFERS THE LOCATION OF THE MELTING LAYER ALOFT IN NRN
AR AND POSSIBLE CHANGE-OVER TO FRZ PRECIP SOON AFTER NEAR THE SFC. AN
EARLIER PASS FROM 1834Z INDICATED 0.02"/HR SNOW-LIQUID EQUIVALENT RATES
ACROSS NERN OK WHERE SNOW WAS OBSERVED. AS CLOUD-TOPS CONTINUE TO COOL
ACROSS NRN TX INTO OK/AR AND ENHANCEMENT CONTINUES TO OCCUR...IMAGINE
THAT 1-2"/HR MAX SNOWFALL RATES ARE POSSIBLE IN THE REGION ALONG THE
COLD SIDE OF THE FRZ LINE OVER THE NEXT SEVERAL HRS.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
