.DISCUSSION...
SOME CONVECTION STARTING TO DEVELOP NEAR AND ALONG SEABREEZE THIS
AFTERNOON. DECAYING MCS NEAR ABI AND BGS HAS PRODUCED OUTFLOW BOUNDARY
EXTENDING FROM NEAR MAF TO NEAR BRADY WHILE WEAK DIFFUSE FRONTAL
BOUNDARY CONTINUE TO LINGER OVER NE TEXAS. MODELS INDICATE HIGH PW VALUES
OVER NORTHERN ZONES LATE THIS AFTERNOON AND INTO EVENING WITH FRONTAL
BOUNDARY SAGGING SLOWLY SOUTH THIS EVENING TO THIS REGION. WE MAY SEE
CONVECTION INCREASING NW OF REGION AND POSSIBLY EXPANDING EAST. WE SHALL
SEE. FOR NOW... WE SHALL LEAVE SLIGHT CHANCE POPS TONIGHT (WHICH MAY
BE ADJUSTED LATER) MAINLY NORTHERN HALF OF CWFA. NEXT SEVERAL DAYS
WILL SEE THE UPPER LEVEL FLOW BECOMING NORTHWESTERLY WITH IMPULSES
MOVING THROUGH MAINLY EAST OF CWFA. SURFACE FEATURES INDICATE WEAK
DIFFUSE BOUNDARY LINGERING OVER CWFA TOMORROW. PRESSURE GRADIENT WILL
REMAIN RELATIVELY WEAK FOR THE NEXT TWO DAYS. WE EXPECT SEABREEZE TO
INITIATE SOME CONVECTIVE ACTIVITY MAINLY DURING AFTERNOON THE NEXT FEW
DAYS. ANY BOUNDARIES FROM FUTURE MCS WILL CHANGE THIS ANTICIPATED
SCENARIO. MAINLY LOW POPS NEXT SEVERAL DAYS. TEMPERATURES EXPECTED TO
REMAIN SLIGHTLY ABOVE NORMS. MODELS INDICATE DEEPENING UPPER TROUGH
OVER EASTERN CONUS LATE THIS WEEKEND/EARLY NEXT WEEK WITH CUT-OFF LOW

.AVIATION...
SEABREEZE BEGINNING TO LIGHT UP JUST EAST OF US. THIS BOUNDARY...
ALONG WITH THE RESIDUAL OUTFLOW FROM LAST NIGHTS STORMS IN N TX
CURRENTLY SITTING ACROSS THE SOUTHERN & CENTRAL ZONES WILL LEAD TO A
CHANCE OF SHRA/TSRA THRU THE EVENING HOURS AS TEMPS CLIMB INTO THE
MID 90S. THOUGH NO WIDESPREAD SEVERE WX IS ANTICIPATED...ANY STRONG
STORMS THAT DO MANAGE TO DEVELOP WILL POSE A RISK OF DOWNBURSTS WITH
A FAIRLY DRY CLOUD SUBLAYER IN PLACE. ANOTHER OUTFLOW BOUNDARY
CURRENTLY SEEN ON SAT PIX MOVING THRU NCNTRL TX MAY ALSO BECOME A
PLAYER LATER THIS EVENING AND POSSIBLY UP TO MIDNIGHT...ESP ACROSS
NRN PORTIONS (CLL & LFK). NAM SHOWING THIS BOUNDARY RE-FIRING THIS
EVENING. DONT HAVE ENOUGH CONFIDENCE TO EVEN MENTION TEMPOS IN ANY
OF THE TAFS AT THIS POINT...WILL WAIT A WHILE LONGER AND SEE HOW
THINGS BEGIN SHAPING UP TOWARD LATE AFTN BEFORE ANY UPDATES.  47
