DISCUSSION

Issued at 1215 AM CDT Thu Oct 22 2026

A ridge axis associated with an Omega block is centered over the southern Plains this morning, while sfc high pressure remains in control over the Great Lakes region. Radiational cooling will favor some patchy shallow ground fog, mainly near bodies of water where exceeding the crossover temperature will be more probable. Otherwise, daily high temperatures today through Monday are progged around 5 degrees above normal as ample sunshine is expected each day. As the omega block begins to break down, the ridge axis nudges more east over the FA by Saturday. Uncertainty in the synoptic details increases Tuesday into Wednesday as the deterministic GFS was previously more amplified with southern and northern stream energy phasing over the Plains. Meanwhile, the ECMWF remains more progressive and zonal in line with the LREF, including the GEFS. Given meager 700 mb moisture and questionable 500 mb forcing, only a 10-15% chance of a sprinkle Tuesday night into Wednesday will be possible as a cold front moves through, bringing more seasonable temperatures.

Patchy ground fog will quickly diminish after sunrise this morning, with VFR conditions prevailing through the remainder of the day. Winds will be northeast around 4-7 kts, diminishing after sunset. Clear skies tonight could yield some patchy fog again early Friday morning, but the probability is around 20% at best.
