.SHORT TERM...
(This afternoon through Sunday night)
Issued at 1147 AM CST Sat Nov 22 2025

Low clouds are currently present across portions of the southern
Texas Panhandle, and if these clouds persist much longer into the
afternoon, will have to adjust temperatures downward. Otherwise,
expecting clouds to clear by the mid to late afternoon.

Meanwhile, latest water vapor imagery shows an upper-level low
spinning just west of Baja California with ALPW showing a plume of
subtropical moisture west of Mexico slowly creep northward by the
cyclonic flow around the upper-level low. This moisture will get
advected into the Panhandles overnight and through tomorrow as the
upper-level system moves east. As this happens, showers with
isolated/brief thunderstorms are favored from Sunday morning through
late Sunday night. Forecast soundings show PWAT values between 0.70"
to 1.00" which is between the 90th to 99th percentile for late
November. However, CAPE looks very meager; less than 200 J/kg. This
suggests that, while the saturated profile will cause this activity
to produce some decent rain rates for late November, the general
lack of instability and limited potential for thunderstorms argues
in favor of more light rain/showery activity rather than moderate
rainfall... though any thunderstorm that can occur will produce a
quick bout of moderate rain.

QPF has been on a downward trend across much of the area, though the
western Panhandles have a better chance to reach or exceed 0.50":
The NBM is showing a 30-50% chance across the western Panhandles, 10-
30% across the central Panhandles; meanwhile the HREF is showing a
10-30% chance across the western Panhandles with a 0-10% across much
of the rest of the CWA. Will lean toward the HREF given the
previously mentioned concerns about relatively low rain rates and
the unfavorable setup for prolonged rainfall.

Rain will come to an end from west to east through Sunday night.

.LONG TERM...
(Monday through next Friday)
Issued at 1147 AM CST Sat Nov 22 2025

An upper-level system will be progressing eastward, away from the
Panhandles, to start Monday. A weak cold front will move in from the
northwest, but the sunny sky will allow for temperatures to warm
into the 60s.

Another upper-level trough is expected to dip into the Northern
Plains on Tuesday as a cold front will push through the Great
Plains. Latest model guidance has the cold front moving through the
Panhandles late Tuesday afternoon and through the evening. There is
a fairly steep surface pressure gradient associated with this cold
front which indicates the potential for breezy/gusty winds along and
behind the cold front.

Wednesday will be a cooler than normal day behind the cold front
with highs expected to be in the low-50s. Surface winds will turn
southerly late Wednesday as a high pressure system shifts off to the
east, allowing temperatures to warm for Thanksgiving; currently
expecting highs ranging from the mid-50s to low-60s for the Holiday.

.AVIATION...
(18Z TAFS)
Issued at 1121 AM CST Sat Nov 22 2025

Fog and low clouds persist over Amarillo at this time, but should
dissipate in the early afternoon hours. Will have to watch for fog
late tonight and into Sunday morning at KGUY and KDHT. Showers
with a low chance for thunderstorms will move in late Sunday
morning into KDHT and KAMA. Have left thunder mentions out of the
TAFs for now given the low confidence of occurring, but may
eventually be needed.
