.PREV DISCUSSION... /ISSUED 239 PM CST Wed Feb 22 2017/

SHORT TERM (Tonight through Thursday Night)...
Upper air analysis this morning showed a low amplitude ridge over
Texas with nearly zonal flow. At the surface, a weak trough was
moving across our northern area. Dew point temperatures were
generally in the 40s and winds were light. The upper level ridge will
move to the east and a trough will move across the southern Rockies
during this period. A cold front will move to our northern border by
the end of the period. The weather will remain dry and temperatures
will be well above normal.

LONG TERM (Friday through Wednesday)...
The cold front will move through our CWA during the morning Friday.
The front will pass through dry and bring drier air and breezy north
to northwest winds. It will also bring temperatures down for the
weekend. Surface high pressure will move to our northeast Saturday
turning the winds around to the southeast. This will return moist low
level air to the region. There may be sufficient moisture and
isentropic lift to produce showers and thunderstorms Sunday. A
dryline and cold front will move through the region in quick
succession Monday and Tuesday bringing another chance for showers and
thunderstorms.
