KEY MESSAGES

- Elevated fire danger concerns will persist through early next week due to very dry ground conditions and low humidity each day.

DISCUSSION

Issued at 210 PM CDT Sat Oct 24 2026

Sprawling high pressure over our region is the primary driver of (no) weather heading into the new week. A highly amplified upper- level ridge axis extends along the Mississippi River this afternoon, while the axis of the surface high pressure system over the Northeast US extends along the Appalachians and over the Gulf Coast. Subsidence and continued dryness has allowed for temps today to warm into upper 70s and lower 80s with a light east wind. Have retained the "Elevated" fire danger graphic for the persistent low humidity and warm temperatures that have stressed and dried out vegetation transitioning out of the growing season. The ridge will be impressed upon by a shortwave trough to our northwest on Tuesday, but do not expect the ridge to be suppressed until mid to late week as western CONUS troughing deepens. Ridge will still be prominent over the southeastern CONUS, and the details of the pattern to our west will be harder to nail down this far out. The general idea in the guidance though is that at least some moist return flow and possible interaction with a shortwave/cold front would be centered around next weekend. Official forecast is an optimistic 15-25% chance for rain in the very final period of this forecast - next Saturday daytime. The synoptic pattern to our west though is highly uncertain with the injection of a strong jet streak into positively tilted trough over the West Coast. Even at 7 days out, guidance begins to diverge over how to resolve the feature as one or as distinct waves. Regardless of any rain chances, temperatures for the upcoming Halloween day/night may push 10 degrees warmer than normal. /NF/
