EVENT...STNRY WARM TOP TSTMS OVER PECOS COUNTY
.
SATELLITE ANALYSIS AND TRENDS...SCT WARM TOP TSTMS HAVE DEVELOPED OVER
SEVERAL COUNTIES FM PECOS WWD AND SWWD. MOST SIGNIFICANT ATTM IS THE
CLUSTER OVER PECOS COUNTY..S OF FST. MANUAL STLT ESTIMATES INDICATE BTWN
1-2" JUST S OF CENTRAL PECOS COUNTY BTWN 2045Z-2145Z..WHERE CELL MERGERS
HAVE TAKEN PLACE AND WHERE THE MAIN STM HAS BEEN STNRY. AN ADDITIONAL 1-2"
IS PSBL.
.
IR AND VIS IMAGERY ANIMATIONS SUGGEST THAT WARM TOP TSTMS WILL CONTINUE
TO INCR OVER THE NEXT COUPLE OF HRS OVER PECOS/REEVES COUNTIES..AS WELL AS
OVER THE COUNTIES TO THE SW. BEYOND THAT..WOULD NORMALLY EXPECT A DECR IN
ACTIVITY WITH SUNSET. HOWEVER..GOES WV IMAGERY ANIMATION SHOWS SUBTROPICAL
JET STREAK HAS SURGED ACRS CENTRAL BAJA AND ACRS W MX..AND IS AIMED TWD
SW TX. THIS MAY RESULT IN PROLONGED CONVECTIVE ACTIVITY OVER PARTS OF
SW TX BEYOND SUNSET. NOT A CERTAINTY..BUT WITH SFC CONVERGENCE MAX AND
PW/RH MAX AS WELL AS THETA E RIDGE OVER THE AREA..AND THE APPROACH OF
THE JET STREAK..THERE IS THE POSSIBILITY THAT ENOUGH ADDITIONAL UPWARD
LIFT WILL BE CREATED TO PROLONG THE CONVECTION.
