PREV DISCUSSION... /ISSUED 302 AM CDT Wed Apr 29 2015/

Light winds, clear skies and cool surface ridging has led to
temperatures rapidly cooling into the 30s and 40s overnight tonight.
Could even see some near or below freezing temps near the Davis Mtns
and Marfa Plateau by sunrise. As a result,a late season Freeze
Warning remains in effect for this area from 5-9am today. Otherwise,
light winds will continue through the day under sunny skies as the
surface ridge slow slides east. High temperatures will warm into the
70s for much of the region today but still remain roughly 5-10
degrees below seasonal normals.

Not much change to the previous forecast package, remaining dry for
the next several days. Still expecting a warming trend through the
end of the week as upper ridging slowly moves east over the area by
the weekend. Meanwhile at the surface, lee troughing will
strengthen, promoting the return of southerly flow to the region.
Above normal temps expected by Friday with afternoon highs generally
in the upper 80s to near 90 most locations through Monday.

Upper ridging will weaken/flatten Sunday, becoming more zonal
through Monday. The dryline looks to return to the region by this
weekend but very little moisture return leave thunderstorm chances
rather low attm. Will see a bit more moisture return Monday
however the dryline may be too far east with only a slight chance
possible across eastern zones. Tuesday, the dryline looks to be
farther west, allowing more moisture return to the region. At the
same time, an Pacific upper trough will approach from the west,
increasing upper forcing for ascent. Tuesday looks to be the
better day for dryline thunderstorms for now and will continue at
least chance PoPs for now.
