   Day 2 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0105 PM CST Sun Jan 21 2018

   Valid 221200Z - 231200Z

   The ongoing forecast is on track with no changes needed.  Elevated
   to locally critical fire weather conditions remain likely across
   portions of Oklahoma, the Texas Panhandle, and into western north
   Texas.  The greatest likelihood of critical thresholds being briefly
   exceeded will occur across the eastern Texas Panhandle and vicinity
   where RH values will fall to near 15% and surface winds will
   approach 20 mph at times.

   See the previous discussion below for more details.

   .PREV DISCUSSION... /ISSUED 0125 AM CST Sun Jan 21 2018/

   ...Portions of the Southern Plains...

   The strong upper low and attendant trough centered over the Plains
   Monday morning will quickly eject northeast toward the Great Lakes
   by the end of the period. Strong deep-layer west/northwesterly flow
   on the back side of this system will persist over the central and
   southern Plains in conjunction with a still-tight surface pressure
   gradient. While the surface pressure gradient will weaken through
   the day, breezy winds are still expected given strength of
   deep-layer flow and deep boundary-layer mixing. Temperatures will be
   cooler, with highs generally in the 50s, but regional forecast
   soundings show mixing to around 4 kft. With PW values near 0.15 in,
   RH values will once again fall into the 12-20 percent range.
   West/northwest winds around 15-20 mph with higher gusts are
   anticipated, and some spotty critical conditions are possible. Winds
   will decrease during the evening and overnight hours as the surface
   pressure gradient relaxes and the upper-level system shifts well
   northeast. RH values also will rebound into the 40-60 percent range.
