Confidence has increased that a period of gusty winds (15-20 mph) could develop across portions of the southern and western Snake River Valley in ID. Concurrent with very warm temperatures and low RH below 15%, several hours of elevated to near-critical fire-weather conditions appear likely atop dry fuels. A small Elevated area has been added to better represent the risk for near-critical fire-weather concerns Friday afternoon and evening. Similarly across the lee of the Cascades and parts of the western Columbia Basin, increasing mid-level flow will foster periodically stronger downslope winds Friday afternoon and evening. Gusts of 15-20 mph may briefly overlap with RH below 20%. However, the strongest winds aloft are likely to be overnight and poorly timed with the lowest RH. While a few hours of dry and breezy conditions appear possible, the lack of greater overlap should keep the fire-weather threat localized. ..Lyons.. 07/04/2024 .PREV DISCUSSION... /ISSUED 0143 AM CDT Thu Jul 04 2024/ ...Synopsis... Similar conditions present over the Interior West today should also occur again for tomorrow (Friday). A mid-level trough will remain in place over the Plains/Mississippi Valley areas as a mid-level anticyclone meanders along the West Coast. Widespread dry conditions (i.e. 10-20 percent RH) should be prevalent by afternoon from the Pacific Northwest to the Desert Southwest. Still, sustained surface winds should remain below 15 mph on the large scale, though terrain-favoring areas may experience localized Elevated conditions. ...Please see www.spc.noaa.gov/fire for graphic product... $$
