Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0204 AM CDT Sat Jun 27 2020 Valid 271200Z - 281200Z ...CRITICAL FIRE WEATHER AREA FOR NORTHWEST NEVADA... ...CRITICAL FIRE WEATHER AREA FOR EASTERN ARIZONA AND WESTERN NEW MEXICO... ...Synopsis... A strong mid-level jet will move into Oregon today as an upper-level trough settles across the Pacific Northwest. This increasing mid-level flow will lead to some critical fire weather conditions in northwestern Nevada. A weak upper-low can be seen in southern Arizona on water-vapor this morning. Slightly stronger mid-level flow is present ahead of this low which may lead to critical fire weather conditions in eastern Arizona and western New Mexico. Isolated to widely scattered dry thunderstorms are expected across a broad region from the Southwest into the Great Basin and central Rockies. ...Northwest Nevada... Strong downslope flow is expected to develop by late this afternoon across northwest Nevada. This will lead to breezy 25 to 30 mph winds across northwest Nevada during the afternoon. In addition, relative humidity is expected to be 12 to 17 percent in the region. ...Eastern Arizona and Western New Mexico... A narrow corridor of stronger mid-level flow (~30 knots) is expected ahead of an upper low on Saturday afternoon. Deep mixing will bring some of these stronger winds to the surface as relative humidity drops below 10 percent. Therefore, a narrow corridor of critical fire weather conditions are expected from eastern Arizona into western New Mexico. ...Isolated Dry Thunderstorms - Much of the Southwest, Great Basin and western Colorado... A broad area of isolated to widely scattered storms are expected to develop across much of the Southwest into the Great Basin and western Colorado. PWAT values in this morning are expected to be in the 0.5 to 0.6" range. In addition, very deep mixing is expected with LCLs above 15 kft. Therefore, storms will likely be on the drier side. ...North-central Oregon and south-central Washington... Downslope flow in the lee of the Cascades will lead to dry and windy conditions across much of central Oregon and Washington. Fuels are still mostly green across this region, but some low-elevation grasses have recently cured in east-central Oregon and south-central Washington. Therefore, a small elevated area has been added in this region. ..Bentley.. 06/27/2020 ...Please see www.spc.noaa.gov/fire for graphic product...Read more
