   Day 3-8 Fire Weather Outlook  
   NWS Storm Prediction Center Norman OK
   0313 PM CDT Fri Sep 21 2018

   Valid 231200Z - 291200Z

   Fire weather concerns will be focused across parts of the Great
   Basin vicinity on Day 3-4/Sun-Mon. An upper trough over the Pacific
   Northwest on Sunday will shift east across the Great Basin to the
   Plains by 12z Tue. Falling heights will lead to strengthening
   westerly deep layer flow while a favorable surface pressure gradient
   across the Great Basin further aids in breezy surface conditions.
   Sunday will be warm, with highs in the 70s and 80s, but a cold front
   will bring cooler conditions on Monday with temperatures about 10-15
   degrees cooler.  As a result, RH values will be lower on Sunday,
   from about 10-15 percent, while more marginal values are expected
   Monday, from 10-25 percent. These conditions should support areas of
   elevated to critical conditions through Day 4/Mon. 

   Thereafter, fire concerns will become more limited as a broad trough
   persists across much of the U.S. through the end of the period.
