A mid/upper trough and associated stronger southwest flow aloft over the northwestern CONUS will present a broad fire weather concern for the eastern Great Basin, portions of the Southwest and central Rockies on Day 2/Monday. Critical highlights remain largely intact across southeastern NV, northern AZ, southern UT and south-central WY where southwest winds of 15-25 mph (locally 30 mph) and RH reductions in the 5-15% range align with receptive fuels. Elevated highlights were extended into the CO Rockies and San Luis Valley based on latest forecast guidance and fuels that are trending drier. ...Northwestern New Mexico... Introduced isolated dry thunderstorm highlights across northwestern NM for Day 2/Monday. A stream of mid and upper level Pacific moisture will continue to infiltrate into the Southwest through Monday morning. Increasing vertical shear at the base of an upper trough moving through the Northern Rockies, daytime instability and sufficient moisture aloft will generate high-based convection across northwestern NM and Upper Rio Grande Valley Monday afternoon and evening. ERC values in the 90th percentile and above suggests fuels more receptive to ignition. This moisture plume will be transient, with a return to dry and breezy conditions for much of the Southwest and Four Corners region beginning on Tuesday as the upper trough ejects into the northern Plains. ...Central High Plains... Adjusted existing isolated dry thunderstorm highlights to reflect latest forecast guidance and expectation for wetting rains associated with potentially severe convection across northeastern CO, NE Panhandle and far eastern WY. Dry lightning risk is still present upon initial thunderstorm (and nascent rain cores) development more adjacent to the Laramie Mountains in WY and CO Front Range in north-central CO. ..Williams.. 06/07/2026 .PREV DISCUSSION... /ISSUED 0122 AM CDT Sun Jun 07 2026/ ...Synopsis... A longwave trough will remain over the northwestern CONUS through the day on Monday, and a shortwave trough will dig across the northern Rockies and Great Basin. This will result in breezy conditions across portions of the Great Basin and the Southwestern CONUS with low RH in place and dry fuels. ...Southwest, Great Basin, and central Rockies... Strong vertical mixing during the afternoon with modest flow aloft is expected to result in winds of 20-30 mph along with RH near 5-15% for several hours across this region. Continued poor RH recovery overnight will contribute to dry fuels. Therefore, a Critical area is introduced across the area. Surrounding this is an Elevated area, where winds are generally expected to be near 15-20 mph with 5-15% RH and receptive fuels. ...Central High Plains... Upslope flow may provide the lift for convective development Monday afternoon in the presence of a relatively dry boundary layer. Precipitable water and storm motions may be a bit marginal, but it appears a mix of wet and dry thunderstorm activity may occur, which warrants an Isolated Dry Thunder area. ...Please see www.spc.noaa.gov/fire for graphic product... $$
