Short term (today through saturday)...
upper air analysis last evening showed split flow across the
country with a northern stream trough from Minnesota to
northeastern New Mexico and a low cutting off west of the Baja California
peninsula. A weak ridge was beginning to move into Texas from
northern Mexico. Flow over the region was from the southwest. At
the surface...high pressure was centered over northeastern Texas.
Winds across our County Warning Area were light from the north through northeast.
Some high clouds were streaming up from the southwest. During this
period...the upper level ridge will build into the Southern
Plains. The surface high will drift to the east turning the winds
to the east and then southeast. This will be a dry period with
temperatures warming...but still below normal.

Long term (saturday night through thursday)...
Saturday night the upper low that was off the coast of Baja California will
begin to move toward the east as an open wave. As this feature
moves across the southwest a series of short wave troughs will
move through the pattern. These will bring chances for rain to our
County Warning Area beginning Saturday night and continuing through Tuesday when
the upper trough lifts away from the area. An upper level ridge
will build over the Southern Plains with dry weather and near
normal temperatures returning for the end of the period.
