Gusty winds east of the Cascades may overlap with ongoing low daytime relative humidities (RHs) to create periods of critical fire weather concerns this Thursday and Friday. On Thursday, RHs in the low teens and wind gusts of 20-30 mph fall short of Warning conditions but do reflect critical conditions. On Friday, RHs may drop into single digits and wind gusts may reach 40 mph in parts of Modoc and southeast Klamath counties. A Fire Weather Watch has been issued to reflect these conditions. For other areas, the combination of low daytime RHs and elevated winds can still help fires grow uncontrollably, even if a Watch or Warning is not present.
