DISCUSSION
ISSUED AT 1238 AM CDT THU JUL 2 2026
THE LARGER WEATHER PATTERN CONTINUES TO BE DOMINATED BY THE STOUT
RIDGE ACROSS THE EASTERN U.S. ISOLATED SHOWERS AND THUNDERSTORMS
WERE SEEN YESTERDAY EVENING ACROSS THE WESTERN PINEYWOODS AND EASTER
SOUTHEAST TEXAS REGIONS. CURRENT CONDITIONS SHOW DECAYING OUTFLOW
AND LIGHT SHOWERS MOVING WEST OF THE I-45 CORRIDOR.
OVERALL, THE FORECAST CONTINUES TO REMAIN STEADY, MAINLY DUE TO THE
STRENGTH AND POSITION OF THE MID-LEVEL RIDGE. THIS AFTERNOON IS
EXPECTED TO BE THE PEAK OF MOISTURE AVAILABILITY AS A WEAK IMPULSE
MOVES INTO THE AREA. SCATTERED SHOWERS AND THUNDERSTORMS LOOK TO
DEVELOP ACROSS THE SOUTHEASTERN TWO-THIRDS OF THE FORECAST AREA
ALONG THE SEABREEZE BOUNDARY. SHOWER COVERAGE WILL BE CLOSER TO
NUMEROUS ACROSS THE NORTHEASTERN GOLDEN TRIANGLE ALONG OUR BORDER
WITH LAKE CHARLES. LOW CHANCES FOR RAIN RETURN FRIDAY AND SATURDAY,
BUT SCATTERED SHOWERS AND STORMS WILL BE POSSIBLE SUNDAY AND MONDAY
AFTERNOONS AS THE MID-LEVEL RIDGE LOOKS TO BREAK DOWN OVER THE
EASTERN U.S.
HEAT CONTINUES TO BE THE MAIN TALKING POINT FOR THE REGION. LATEST
GUIDANCE HAS SLIGHTLY REDUCED THE COVERAGE OF SOME OF THE HIGHER
VALUES BETWEEN 108-110F (42-43C), BUT ISOLATED LOCATIONS MAY STILL
REACH THIS RANGE FRIDAY AND SATURDAY. WITH THIS WEEKEND DOUBLING AS
A HOLIDAY WEEKEND AND A MATCH DAY, CONSIDERATION FOR A HEAT ADVISORY
WILL NEED TO BE MAINTAINED. IF YOU PLAN TO SPEND THE DAY OUTDOORS,
MAKE SURE YOU WEAR LIGHT CLOTHS, APPLY SUNSCREEN AND STAY HYDRATED
BY DRINKING PLENTY OF WATER. ALSO TAKE PLENTY OF BREAKS FROM THE
HEAT BY SEEKING SHADE/AC.
