NWS has issued a Freeze Warning for the entire area including the
coastal locations for tonight.
Hard freeze is expected along and north of a line from Katy to Spring
to Liberty with upper 20's to lower 30's south of this line.
Strong 1042mb high over central KS will build into NE TX this
afternoon and park over SE TX tonight. With clear skies and light
winds a strong radiation inversion will set up shortly after sunset
and the temps will drop quickly toward the dewpoint (upper teens and
low 20's).
Temps:
With dewpoints currently in the teens from College Station to Lufkin
lows in the upper teens to 22 are possible over the northern counties.
North of the Katy to Spring to Liberty line lows will be in the 20-25
range and 25-32 over the rest of the area. Winds and "warm" water
along the coast may prevent a freeze right on the water with lows from
32-34. It should be noted that any wind mixing tonight will result in
lows several degrees warmer than current forecast, however a
completely decoupled boundary layer will result in temps at the
dewpoints tomorrow morning.
Model Forecast Lows for tonight:
BUSH:
ETA 27
NGM 23
MAV 24
GFS 21
College Station: 19-21
Lufkin: 16-20
Hobby: 27-31

Impacts:
Should temps. reach their forecasted lows it will be a killing freeze
for most of the area. Tender vegetation will be severely impacted if
not completely destroyed (including tropical plants, citrus trees,
ect). Temps. will be at or below freezing for 7-10 hours within the
Hard Freeze area and 3-5 hours outside the 610 Loop. Outside spinkler
systems and water faucets should be protected north of a Katy to
Spring to Liberty line.
We may see more freezing temps. this weekend with another cold front
on Friday. Stay tuned.
Extended:
Arctic event with extremely cold air still appears possible the week
of Christmas, although this mornings model runs have pushed it back
until Christmas Day and the week between Christmas and New Years.

Today: sunny but cold with highs in the low 50's. North winds 5-10mph
