SHORT TERM...
(Today and Tonight)

A cold front will move through West Central Texas this morning,
resulting in northwest winds of 10 to 20 mph, with higher gusts.
Slightly cooler temperatures are forecast today, with highs in the
upper 50s to lower 60s. Winds overnight will gradually decrease,
becoming light and variable after midnight. This in combination with
dewpoints in the teens and clear skies will result in good
radiational cooling conditions. Overnight lows will be in the upper
20 to lower 30s, with low lying areas and river valleys possibly
dropping into the mid 20s.

Fire Weather...
A cold front will move through the area this afternoon, resulting in
northwest 20 foot winds increasing to 15 to 20 mph, with higher
gusts. In addition, minimum relative humidity values will fall to 15
to 20 percent, resulting in elevated to near critical fire weather
conditiions. Portions of the northern and eastern Big Country may
briefly see Red Flag Warning (RFW) conditions, but have opted to
issue a Rangeland Fire Danger Statement for much of the area, as
most locations look to remain below RFW criteria. Minimum relative
humidity values on Tuesday and Wednesday will once again drop to 15
to 20 percent, but 20 foot winds are forecast to remain light.

LONG TERM...
(Tuesday through Sunday)

Quiet weather in the long term continues. Upper level ridge shifts
across the area through mid week, before a trough moves across the
Plains for Friday into the Weekend. Dry with temperatures very
close to seasonal normals through Thursday Night. A little warmer
ahead of a cold front that may also help develop a few showers and
storms across the Hill Country and Heartland east of a Brownwood
to Junction line. Friday is the warm day with highs in the upper
60s, with temperatures dropping back into the upper 50s and lower
60s for the weekend.
