I know we don't ordinarly provide weather reports....but for those of you in Texas that usually don't worry about freezing....READ THIS.
Summary is that it has been fairly cool lately so building/surface temps are mild. Temps Friday nite in the 20s with possible snow. Mid 20s after two days in the 40s can freeze your block/heater.
PREPARE for this .... or risk "or else".

defying all logic ... it appears that mother nature has thrown
southeast texas a bit of a curve ball or should we say a snow
ball? models have come into better agreement that moisture levels
will be sufficiently deep and thermal profiles sufficiently cold
to give the area snow. isentropic upglide is maximized during the
late morning and early afternoon and precipitation should become
widespread. forecast soundings show pw values near 0. 8 inches
which is robust for this type of air mass. forecast soundings also
reveal a saturated profile below 0c from about 975mb and up. only
the lowest 1000 feet of the atmosphere will be above freezing and
this will likely cool with evaporative effects. the ground is warm
so am expecting some melting before snow begins to accumulate on
grassy and elevated surfaces. southeast texas will lie in a right
rear quad which will assist in lift. all the ingredients are in
place so what can go wrong? plenty!! it is difficult to determine
when the precipitation will change over to snow and if the period
of snow is shorter than currently diagnosed ... amounts will be
lower. warming from the gulf could affect the thermal profile as
well altho not likely with surface winds out of the north. at this
time ... it appears that 1 to 3 inches of snow will fall across
areas along and east of us highway 59 with slightly lower totals
northwest of this corridor. a winter storm watch has been issued
for the entire cwa for friday. north winds of 15 mph combined with
the falling temps will produce wind chill values in the mid 20s.
temperatures will plunge friday night as skies clear. if snow is
on the ground ... min temps sat am will fall into the lower 20s. any
wet spots will freeze fri nite so motorists will need to be very
careful if driving especially on the elevated bridges. max temps
on saturday are tricky too. if snow is on the ground to start the
day ... max temps will never reach the lower 50s. basically the temp
forecast is a work in progress depending on how things pan out on
friday. another s/wv approaches the area on sunday. this feature
coupled with warm air advection will bring a quick shot of rain
sunday and sunday evening. another shot of rain on tuesday with a
weak front. 43
