Fire Weather Outlook
— Day 1
Synopsis
Weak and diffuse upper-level troughing will continue over the Southwest while a mid-level shortwave trough traverses the Northwest. Winds will increase across northeastern Nevada into southern Idaho ahead of the shortwave and an associated dry cold front, overlapping a dry airmass. Sustained surface winds of 15-20 mph (gusts up to 35 mph), above normal temperatures, and 10-15% RH are expected by peak heating. While some green-up is in place over the area, enough continuity of very dry fuels coincident with previously mentioned weather conditions will maintain Elevated fire weather concerns, accompanied by locally critical in terrain-favored areas.
Isolated to scattered mixed wet/dry thunderstorms are likely again across portions of far eastern Arizona into western New Mexico and southern Colorado this afternoon. Storms east of the Rio Grande Valley will be mostly wet with drier storms along/west of the Divide. However, with weak steering flow storms are likely to linger over areas, especially on the higher terrain. Additionally, slightly deeper moisture may work its way into portions of eastern Arizona, which would also limit the potential for drier thunderstorms. Fuels remain dry, but some areas will have a second consecutive day of thunderstorms, which may help limit ignition potential.
The upper-level ridge will begin to flatten over the Upper Midwest and Great Lakes, but the stronger winds will be displaced from the lowest RH. Regardless, fuels remain very dry across these areas (90th+ percentile) amid above normal temperatures and lower RH.
