From the National Weather Service office in PAH, issued 6 hrs ago

Key Messages

- Seasonable temperatures trend around 5 degrees above normal during the latter half of this week into the weekend.

- Dry conditions will persist over the next 7 days with no precipitation.

Discussion

Issued at 1250 AM CDT Tue Oct 20 2026

An omega block will continue to provide tranquil weather conditions with seasonable temperatures as sfc high pressure remains in control over the Great Lakes region. While the ridge axis begins to shift more east from the Plains into the lower Ohio Valley during the latter half of the week, the only noteworthy change will be temperatures warming around 5 degrees above normal due to southerly return flow. Highs will range from the mid to upper 70s with lows struggling to dip below 50 degrees by the weekend. There are signs on some of the model guidance that a cold front will eventually impact the FA towards the middle of next week as a potent trough ejects across the northern Plains. For the foreseeable future, no precipitation is expected over the next 7 days that would provide relief from the abnormally dry to moderate drought conditions.

Aviation

Issued at 627 PM CDT Mon Oct 19 2026

Can't rule out some patchy ground fog late tonight through sunrise, mainly at PAH/CGI and near any water bodies. Otherwise, VFR conditions expected with only some SCT high cloud. Calm winds overnight will become light 3-5 kts out of the northeast tomorrow afternoon.
