   ...Synopsis...
   A similar upper-level pattern to Wednesday is expected on Thursday.
   Broad cyclonic flow will persist across the West, Plains, and Upper
   Midwest. Some amplification of a ridge within the south-central U.S.
   is forecast. The southern Great Basin boundary will lift northward
   bringing precipitation to more of the central Great Basin.

   With a belt of stronger mid-level winds remaining in the Southwest,
   another day of dry and breezy conditions are probable in southeast
   Arizona into parts of central New Mexico. With another day of drying
   on Wednesday, it is possible that fire weather concerns will be
   slightly increased on Thursday. Still, winds will be on the marginal
   side (mostly around 15 mph). The current expectation is that only
   locally elevated conditions will occur.

   As thunderstorms shift northward from Wednesday, some activity will
   shift into areas that have not had fuel indices reduced by multiple
   convective days. However, scattered storms are expected with aided
   lift from the boundary and storm motions are not expected to be
   fast. This all suggests a primarily wet storm mode and limited
   lightning ignition risk.

   During the extended range, the upper-level flow pattern will undergo
   a change over the CONUS.  The upper-level pattern is forecast to be
   characterized initially on Friday (Day 3) by broad cyclonic flow,
   and then transition to a trough in the eastern CONUS and ridge in
   the West by Sunday (Day 5), as a strong shortwave trough dives
   southeastward out of Canada into the Northern Plains and Great Lakes
   Region.  As a result, there will be a warming and drying trend over
   much of the West with an increasing probability of widespread
   critical RH values as far north as eastern Washington.  The
   concurrent probability of surface wind speeds exceeding 20 mph,
   however, is expected to be low given the forecast of weak lower- and
   mid-tropospheric flow.  A series of weak shortwave troughs are
   forecast to move under the ridge in the West beginning on Monday
   (Day 6), which may increase the threat of dry thunderstorms across
   the area, but predictability is too low to warrant highlights at
   this time.
