DISCUSSION
ISSUED AT 1221 PM CDT MON JUL 6 2026
A MID-LEVEL LOW PRESSURE SYSTEM OVER THE SOUTHERN PLAINS IS
INFLUENCING OUR REGION, SUPPORTING ANOTHER ROUND OF ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS TODAY.
CONDITIONS ARE CONDUCIVE FOR CONVECTION, WITH PWAT VALUES NEAR 1.8-
2.1 INCHES, AMPLE INSTABILITY, AND LITTLE TO NO CAPPING. HOWEVER,
SOME MID LEVEL DRY AIR MAY BE AN INHIBITING FACTOR, SIMILAR TO WHAT
OCCURRED OVER THE WEEKEND. WHILE THERE IS A LOW PROBABILITY OF MCS
DEVELOPMENT OVERNIGHT IN OUR NORTHERN AREAS, SMALL SCATTERED STORMS
DURING THE LATE AFTERNOON ARE THE MORE LIKELY SCENARIO. IN THE EARLY
MORNING FROM 6AM-8AM PATCHY FOG ALONG THE WEST SIDE OF I-45 CAN BE
EXPECTED.
SLIGHTLY DRIER AIR WILL MOVE INTO THE AREA TUESDAY INTO WEDNESDAY
GRADUALLY DECREASING PRECIPITATION CHANCES. SOME SCATTERED SHOWERS
ARE STILL EXPECTED TUESDAY, WITH HIGHEST CHANCES CENTERED AROUND THE
PINEY WOODS REGION. PRECIPITATION CHANCES WILL CONTINUE TO DECREASE
INTO LATE WEDNESDAY AND THURSDAY AS A PLUME OF SAHARAN DUST WILL BE
ARRIVING, BRINGING EVEN DRIER AIR, POSSIBLE HAZE, AND REDUCED AIR
QUALITY.
TEMPERATURES THROUGHOUT THE WEEK WILL REMAIN IN THE MID TO HIGH 90S
WITH HEAT INDICES APPROACHING ADVISORY LEVEL BY THE END OF THE WEEK.
HOWEVER, FRIDAY INTO THE WEEKEND WILL ALSO SEE MORE WIDESPREAD
SHOWERS/STORMS THAN WHAT HAVE BEEN SEEN OVER THE LAST WEEK. WHETHER
OR NOT HEAT ADVISORY CRITERIA WILL BE MET WILL DEPEND ON THE TIMING
AND LOCATION OF THESE SHOWERS AND THUNDERSTORMS.

AVIATION
(12Z TAF ISSUANCE)
ISSUED AT 601 AM CDT MON JUL 6 2026
SIMILAR TO THE LAST FEW MORNINGS, WE ARE STARTING TO SEE SOME
MVFR CIGS/VIS DEVELOP. THIS SHOULDN'T LAST TOO LONG WITH VFR
PREVAILING BY 13-14Z. SOUTHERLY WINDS WILL INCREASE TO AROUND 8-10
KNOTS THIS AFTERNOON THEN BECOME LIGHT AND VARIABLE DURING THE
EVENING HOURS. GLS LOOKS TO REMAIN AROUND 10 KNOTS THROUGH THE
NIGHT. THERE IS A LOW CHANCE FOR SHOWERS AND STORMS ACROSS THE
REGION THIS AFTERNOON. CONFIDENCE IS LOW IN IMPACTS AT ANY
PARTICULAR TERMINAL AT THIS TIME SO HAVE LEFT ANY MENTION OUT OF
THE TAFS. OTHER THEN THE RISK OF MIST/FOG CONDITIONS WILL REMAIN
VFR.
MARINE
ISSUED AT 1221 PM CDT MON JUL 6 2026
LIGHT ONSHORE WINDS (AROUND 10 KT) AND LOW SEAS (1-3 FT) WILL
PREVAIL THROUGH AT LEAST MIDWEEK. TOWARDS THE END OF THE WORK WEEK,
WINDS SLIGHTLY INCREASE AND COME CLOSE TO THE CAUTION FLAG THRESHOLD
AT TIMES DURING THE NIGHTTIME HOURS. THESE INCREASED WINDS WILL ALSO
INCREASE OFFSHORE SEAS TO AROUND 3-4 FT AND COULD LEAD TO AN
INCREASING RISK OF RIP CURRENTS GOING INTO THE WEEKEND. SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS WILL BE POSSIBLE OVER THE WATERS
DURING THE MORNING TO EARLY AFTERNOON HOURS BEFORE RAIN ACTIVITY
SHIFTS INLAND ALONG THE SEA BREEZE.
