Slightly cooler temperatures in the upper 70s to lower 80s expected on Monday and Tuesday as an upper-level trough translates east across the region. Southwest flow aloft ahead of the trough to bring increased cloud-cover to the region. However, with insufficient moisture return ahead of the trough, dry conditions to persist.

(12Z TAFS) Issued at 551 AM CDT Sat Oct 24 2026

Still only very high and thin cirrus is all we will have to deal with today across our airspace. Some hint of some low level returns along with fog developing inland of the SW LA coast should remain south of the LFK terminal this morning. Model time height cross sections hinting at the possibility of a very weak cu field late this afternoon across mainly our NE TX terminals but chose to leave this out of the 12z package as no ceilings are expected if we see this cloud cover at all. Winds will gradually become southeast later this morning with speeds generally under 10kts.
