   Broadly cyclonic flow aloft will exist across much of the Lower 48
   today as a series of progressive shortwave troughs migrate eastward
   across the northern Plains and Great Lakes region.  Broad height
   falls in the central Rockies will aid in continuing to weaken the
   Southwestern U.S. ridge throughout the day.  At the surface, high
   pressure will build into the Rockies and adjacent Plains, which will
   result in a tempering of low-level wind fields in most areas during
   peak heating hours.  Although very hot and dry conditions will
   likely exist during the afternoon and early evening, notable fire
   weather concerns will be limited to a small part of southern
   California as weaker wind fields and a lessened thunderstorm risk
   will mitigate the overall fire weather risk elsewhere.

   ...Southern California...
   Gusty, southwesterly onshore flow will once again occur during the
   afternoon and evening hours in coastal ranges, exceeding 20mph at
   times.  The near-coastal airmass will quickly modify with inland
   extent as a result of insolation and surface heating, with 90s-100
   degree F surface temperatures and 10-15% RH becoming common.  Fuels
   will also be dry across the region.  An elevated fire weather
   delineation has been made to address this threat.
