   Dry offshore flow is forecast to continue across inland areas of
   southern California into Day 2/Thursday morning. Despite minimum RH
   values near 15%, the surface high over the Great Basin is expected
   to weaken throughout the day, which will relax the pressure gradient
   and keep sustained surface wind speeds generally at or below 15 mph.
   Furthermore, the influence of the surface high on the low-level flow
   will dwindle by afternoon, as it gradually shifts farther southeast
   and onshore flow re-develops. While near elevated fire weather
   conditions could briefly develop -- especially during the morning
   when wind speeds are greatest -- it currently appears that reduced
   RH values and elevated surface wind speeds will not overlap for a
   long enough duration and/or over a large enough area to warrant the
   introduction of an Elevated fire weather area.

   The amplified, west-to-east ridge-trough pattern will continue
   through Thursday. Thus, the warm/dry conditions across the Southwest
   and Great Basin, albeit with light winds, will also continue. Across
   the East, the mid-level flow should relax slightly ahead of the next
   in a series of short-wave troughs. This relaxation of the mid-level
   flow should result in lighter surface winds than on Wednesday. Thus,
   despite the continued dry conditions across the Plains, there are no
   fire-weather concerns at this time.
