Look for VFR conditions to continue for the next 24 hours. A
surface trough of low pressure, across eastern New Mexico, will
produce gusty southerly surface winds today. Otherwise, expect
southerly surface winds around 10 knots.
.PREV DISCUSSION... /ISSUED 400 AM CDT WED AUG 20 2014/
(Today and Tonight)
A dry forecast has returned to West Central Texas. The weak upper
low, which brought rain to much of West Central Texas over the last
several days, has moved east. High pressure aloft will again
dominate. Highs today will be slightly warmer in most areas, with
more sunshine today than the last several days. Overnight lows
tonight will be near seasonal normals.
(Thursday through Tuesday)
Our dominant weather influence will be an upper high, which
builds over the lower Mississippi Valley late this week. A
gradual warming trend ensues during the next few days as
850mb thermal ridge expands east into West Central Texas.
During the weekend, center of the aforementioned upper high
will shift north over western Tennessee and western Kentucky.
Our area will be on its western periphery. May have a few weak
shortwaves lift northeast from southern New Mexico across far
west Texas and the Panhandle, into northwestern Oklahoma. Any
associated convection is expected to stay west and northwest of
Early next week the upper high is progged to be centered over
Kentucky, with our area on the southwestern periphery. A fairly
deep upper trough is progged to extend from the northern
Rockies into Nevada and Utah, and may have continued weak
disturbances moving out of southern New Mexico and into the Texas
Panhandle. A steady-state pattern is indicated with our
temperatures during the weekend and first part of next week, with
highs expected to be a few degrees above normal. The warmest
readings will be across our northernmost counties.
