that will move across the area, bringing gusty north winds
and cooler temperatures areawide. The front is expected to
reach the I-20 corridor around 8 AM and clear the I-10 corridor

front and continue into the afternoon hours before diminishing
towards sunset. The current Wind Advisory looks good and no
changes are planned at this time, with the advisory covering
all but Sutton, Kimble and Mason counties. Temperatures will
be much cooler today, with highs ranging from the lower 60s
north, to the lower 70s along the I-10 corridor.

Surface high pressure will build south across the area tonight,
with winds subsiding. The light winds, clear skies and a dry
airmass will promote ideal radiational cooling overnight, allowing
temperatures to fall into the low to mid 30s by daybreak Sunday.

mid 30s, below normal temperatures are forecast on Sunday, with
