   Day 2 Fire Weather Outlook

   Valid 021200Z - 031200Z

   ...Afternoon Update...
   Only minor adjustments were made to the Isolated Dry Thunder risk
   area based on recent guidance. Increasing mid-level moisture
   alongside afternoon heating and resultant instability will promote
   isolated showers and thunderstorms, maintaining a threat of some
   lightning ignitions across western NM, far southwestern CO, and
   east-central AZ. Owing to antecedent weather conditions aiding in
   curing the landscape, fuels are expected to be receptive and
   conducive to fire spread as storms produce localized erratic wind
   gusts with little accumulating precipitation (<0.25").

   .PREV DISCUSSION... /ISSUED 0125 AM CDT Mon Jun 01 2026/

   ...Synopsis...
   Fire weather concerns for Tuesday will primarily be associated with
   dry lightning potential across parts of far eastern Arizona and
   western New Mexico. A weak upper wave is evident off the Baja CA
   coast that will migrate east towards the Southwest over the next 24
   hours. Weak pressure falls across the interior West will promote
   eastward low-level moisture transport into the southern Rockies. The
   western periphery of the moist plume should spread into eastern AZ
   by Tuesday afternoon with PWAT values on the order of 0.4 to 0.5
   inch. While modest, this will provide sufficient buoyancy to support
   isolated thunderstorms as weak ascent overspreads the region ahead
   of the approaching wave. A deeply mixed boundary layer and 15-20
   knot storm motions will help limit rainfall amounts and support the
   potential for dry lightning strikes over a region with receptive
   fine fuels after several days of warm and dry conditions.

   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0456 PM CDT Mon Jun 01 2026

   Valid 031200Z - 091200Z

   ...Synopsis...
   An upper low will begin to traverse southern Canada on Day
   3/Wednesday while surface high pressure and associated dry
   conditions amid light winds persist over the Great Lakes.
   Concurrently, an upper low moves offshore the Eastern Seaboard,
   allowing the ridge of high pressure to slide over the eastern CONUS.
   Recent appreciable precipitation across the High Plains through the
   Southeast will keep broader fire weather concerns low through the
   week. A robust upper trough is expected to enter the Pacific
   Northwest on Day 5/Friday, allowing fire weather concerns to emerge
   across the Intermountain West.

   ...Portions of the Southwest and Great Basin...
   ...Day 3/Wednesday...
   Deeper atmospheric moisture and sufficient buoyancy will approach
   portions of the Southwest on Day 3/Wednesday, promoting widespread
   thunderstorms east of the Rio Grande Valley. Isolated convection
   west of the Continental Divide and lower PWATs may allow some threat
   of lightning ignitions to evolve. Slower storm motions prevent the
   introduction of Dry Thunderstorm probabilities at this time, though
   may be considered in future outlooks.

   ...Day 6-7/Saturday-Sunday...
   Increasing southwesterly mid-level flow ahead of an approaching
   upper-level trough should encourage a dry and breezy environment to
   emerge across the Great Basin and Southwest on Day 6/Saturday. 40%
   Critical probabilities have been introduced where extended guidance
   and ensemble probabilities denote a broad area of low RH and strong
   winds. As a result of the overall pattern, fire weather concerns may
   continue into Day 7/Sunday, however ambiguity in the progression of
   the upper trough precludes the introduction of probabilities.

   ...Great Lakes...
   ...Day 3-4/Wednesday-Thursday...
   The upper ridge will begin to flatten on Day 3/Wednesday as an upper
   low traverses southern Canada. Warm daytime temperatures and RH
   declining to less than 35% on Day 3/Wednesday and Day 4/Thursday
   could allow fire weather concerns to emerge where favorable fuels
   exist. However, misaligned breezy winds/critical RH limit broader
   fire concerns.
