/06Z TAFS/

Another clear and cool night is on tap with light winds mainly
from the east. As a result, some local reduction of visibilities
may occur after 4am due to fog/mist. Unlike last night, we do not
expect the visibility to be reduced below one mile. Any fog or
mist that does develop by sunrise should quickly dissipate within
a couple of hours. For Wednesday, light winds should become
southerly and southeasterly at around 5KT at all terminals.
Clouds will increase by early afternoon, with MVFR conditions and
showers possible by late afternoon for places such as Brady and
Junction. Ceilings and precip should continue through Thursday
night before they move out.

Skies are clear this evening across much of west Texas with light
winds mainly from the east. Another clear night is in store with
light and variable winds. For tomorrow, new model guidance
showing even lower rain chances than earlier runs. As a result,
we have lowered PoPs for tomorrow and have shown the best chances
for tomorrow afternoon. Grids have been updated to reflect this

(Tonight and Wednesday)

Quiet weather tonight underneath low amplitude ridging aloft, and
an exiting area of surface high pressure. Winds will turn more
southerly during the overnight hours. Low temperatures should be a
few degrees warmer tonight, but our low spots could still see
temperatures close to or below freezing.

For Wednesday, a weakening upper level trough will move through
the area, bringing mainly increasing cloudiness, but there is
still a slight chance for isolated to scattered showers across the
region, so have left some slight chance PoPs in the forecast.
Although we will be mostly cloudy, temperatures will still warm
into the mid to upper 50s, but it will likely feel a little cooler
than today with the clouds and scattered showers around.


(Wednesday night through Tuesday)

A nice warming trend will continue Thursday into Saturday with
dry zonal flow aloft, with colder air on Sunday with a cold

Breezy southwest to west winds are expected late Thursday night
into early Friday afternoon, and again during the day Saturday, as
surface lows move across Oklahoma. Winds and highs were adjusted
higher to account for the subsident, downslope westerly component
on the winds. Gusty northwest winds are expected late Saturday
night into Sunday, as a cold front moves through. Winds should be
weaken Sunday mid-afternoon. As the origin of the cold air Sunday
is in the Central Rocky Mountains, highs Sunday into Tuesday,
will be mainly in the 50s to lower 60s.
