See previous discussion for details. ..Nauslar.. 05/23/2018 .PREV DISCUSSION... /ISSUED 0803 AM CDT Wed May 23 2018/ ...Synopsis... The greatest risk of fire weather today will occur across portions of the Southwest and southern Rockies. 35-45 kt flow will continue to overspread these areas in response to a weakening mid-level low that will lift northward from the Great Basin into the northern Rockies. At the surface, a dry airmass will remain in place from Arizona into western New Mexico and spread east/northeast during the day toward central New Mexico and south-central Colorado along and west of a weak lee surface trough. The net result of this pattern is elevated fire weather conditions across much of the region. ...Eastern Arizona, western/central New Mexico, and southern Colorado... Surface flow will range from 10-20 mph in most areas during peak heating in response to vertical mixing and a modest surface pressure gradient. Additionally, as temperatures rise through the 70s and 80s F, RH values will fall below 15% areawide and fall into the single digits across central New Mexico and vicinity. Localized areas of 20+ mph surface winds will develop in terrain-favored areas from central New Mexico northward to south-central Colorado. These conditions, in conjunction with dry fuels and areas of continued drought, are consistent with elevated fire weather, and an attendant delineation remains in place. ...Please see www.spc.noaa.gov/fire for graphic product...
