DISCUSSION

(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.

AVIATION

(18Z TAFS) Issued at 1203 PM CDT Sat Jun 20 2026
