   Valid 021700Z - 031200Z

   ...17Z Update...
   The previous forecast remains valid and largely unchanged. An
   expansion of the Southern Plains Elevated area further southwest
   into Central TX was introduced in order to cover hot, dry, and windy
   conditions this afternoon and early evening that overlap with
   supportive fuels. Localized dry and breezy conditions may occur
   across Southwest OR. However, no Elevated highlight will be
   introduced at this time. See previous discussion for more
   information.

   .PREV DISCUSSION... /ISSUED 0143 AM CDT Tue Jul 02 2024/

   ...Synopsis...
   Broad cyclonic mid-level flow will overspread much of the
   northwestern and north-central CONUS today, with an embedded
   mid-level impulse overspreading the northern Plains as a 500 mb jet
   max impinges on the Pacific Northwest. Coincident with low pressure
   development in the Central California Valley region, 15+ mph
   sustained northerly surface winds may develop by afternoon in the
   Sacramento into Napa Valleys as RH drops to or just below 15
   percent. Given receptive fuels in this region, Elevated highlights
   have been maintained. 

   Locally dry and breezy conditions should also develop along the lee
   of the Cascade Ranges into the Harney and Columbia basins in eastern
   Oregon and Washington (respectively). Fuels continue to cure across
   the Pacific Northwest, but are currently only modestly receptive at
   best on a widespread basis. Given the localized nature of the dry
   and breezy conditions, and given modest fuel receptiveness, no fire
   weather highlights have been introduced.

   Finally, surface low development over the central Plains will
   encourage dry southerly low-level flow over the southern High Plains
   as the boundary layer deepens and mixes by afternoon. Latest
   guidance consensus depicts 15-20 mph sustained south-southwesterly
   surface winds overlapping 20-25 percent RH for at least a few hours.
   Given the stress of fuels under hot conditions over the past few
   days, fuels may be receptive enough to support wildfire-spread
   potential, hence the maintenance of Elevated fire weather
   highlights.
