(THIS EVENING THROUGH NEXT FRIDAY)
ISSUED AT 1209 PM CDT SAT JUN 20 2026
A FRONTAL BOUNDARY HAS STALLED NORTH OF THE LOCAL REGION, HOWEVER
DEEP MOISTURE CONTINUES TO STREAM ACROSS THE AREA ALONG AND SOUTH
OF THE OLD BOUNDARY. TROUGHING IS OVER A LARGE PORTION OF THE
EASTERN CONUS WITH SHORT WAVES PASSING ACROSS THE SOUTHERN STATES
AROUND THE BOTTOM OF THE LARGER TROF. THESE DISTURBANCES ARE
INTERACTING WITH THE WEAKENING SURFACE BOUNDARY AND HIGH PWATS TO
FORM SCATTERED TO NUMEROUS STORMS CAPABLE OF PRODUCING VERY HEAVY
RAIN ACROSS SE TX AND S LA.
CONVECTION IS EXPECTED TO GRADUALLY DECREASE THIS EVENING AS
HEATING IS LOST, HOWEVER A FEW STORMS MAY LINGER THROUGH THE
NIGHT AS THE BOUNDARY REMAINS NEAR.
SUNDAY INTO MONDAY A RIDGE WILL BEGIN TO BUILD IN ALOFT. ISOLATED
AFTERNOON STORMS WILL BE POSSIBLE SUNDAY, BUT RAIN CHANCES WILL BE
NEAR 0 FOR MONDAY. NO RAIN IS ANTICIPATED TUESDAY. WITH THE LACK
OF CONVECTION AND CLOUD COVER, APPARENT TEMPS WILL CREEP UP TO
NEAR HEAT ADV CRITERIA OF 108F, BUT MAINLY ACROSS INTERIOR
LOCATIONS.
THE RIDGE ALOFT MAY HOLD THROUGH THE REMAINDER OF THE WEEK KEEPING
THE AREA HOT, HUMID, AND MOSTLY RAIN FREE, HOWEVER A WEAK BACK
DOOR FRONT MAY MOVE CLOSE ENOUGH TO PROVIDE A LOW END CHANCE OF
RAIN FOR CEN LA BY THURSDAY OR FRIDAY.
