Discussion

Issued at 106 AM CDT Wed Oct 21 2026

Recent WV sat imgry depicted perturbed upper level flow over the CONUS, w/ an upper low approaching Srn CA and the Baja region, and another upper low maneuvering over the NErn US. Intermediate ridging resided over the Cntrl US, w/ broad sfc high pressure extending SEwrd fm the Great Lakes thru the OH River Valley and Mid-South.

Thru much of the current fcst PD, there is considerable agreement amongst deterministic and ensemble global guidance for upper level ridging to persist across the central CONUS. This wl drive a persistence-style fcst, w/ daily high temps in the upper 70s to low 80s...typically above-normal for most locations...and lows in the upper 40s to low 50s, w/ no appreciable rainfall expected.

Concerning drought and fire danger, a lack of forecast rainfall, and any recent substantial rainfall wl foster drying ground fuels (noted by fcst ERC values approaching >90th percentile over portions of Srn AR), and persisting to deteriorating drought conditions for much of the state. Additionally, very low afternoon RH values of 25 percent or less may contribute to daily elevated fire danger concerns through at least this weekend.

For the long term, the aforementioned west coast trof looks to slowly translate Ewrd over the Four Corners region into early next week, weakening as it does so. Locally, the center of the upper level high wl also shift Ewrd, positioning SWrly flow acrs the Srn Great Plains, and possibly driving some poleward moisture transport by mid- week next week, but confidence remains low, w/ most ensemble guidance pointing towards zonal H500 near the end of the fcst PD and beyond.
