With the mid-level trough near the Four Corners moving to the east, the risk for isolated dry thunderstorms has been shifted east accordingly. Additionally, some locally elevated conditions are possible along the lee of the northern California coastal ranges, with guidance depicting some potential for terrain-enhanced downslope flow with near-critical values of RH. However, fuels in the area are not particularly dry, so will decline to introduce highlights. ..Supinie.. 06/14/2024 .PREV DISCUSSION... /ISSUED 0153 AM CDT Fri Jun 14 2024/ ...Synopsis... A midlevel trough and belt of south-southwesterly flow aloft will advance east-northeastward across the Southwest on Friday. A surface low south of south-central NM will promote modestly breezy westerly surface winds across southeastern AZ and southwestern NM. Given a deep/dry boundary layer across the area (single-digit RH), elevated to locally critical fire-weather conditions are expected. The primary limiting factor for the addition of a Critical area continues to be marginal surface winds (15-20 mph). Across northern Arizona on the fringe of better moisture located across the Four Corners into western New Mexico, isolated dry thunderstorms will be possible along the Mogollon Rim. Enhanced westerly flow aloft will move into the base of a mid-level trough across the Northwest Friday afternoon. The associated downslope flow across the Cascades and Sierra will favor locally dry/breezy conditions across portions of northwestern NV and eastern WA/northeastern OR where fuels have dried sufficiently to support fire spread. As a result, elevated conditions are expected for both areas, with locally critical conditions possible in northwestern NV -- where 20-25 mph sustained westerly surface winds are expected. ...Please see www.spc.noaa.gov/fire for graphic product... $$
