not much to change on the morning update as the current forecast
package looks on track. After morning lows at or below freezing
across almost all of inland southeast texas, lots of sunshine
today will help to warm temperatures into the upper 40s to lower
50s. Surface high pressure centered over the area tonight along
with the clear skies will allow most inland low temperatures to
bottom out in the the upper 20s to lower 30s. Locations in and
around the bays and also at the coast will stay above freezing.

short term [today through Friday]...

high pressure is steadily building in from central texas,
causing skies to become clear and moderate north winds to dampen.

With little cloud cover to insulate the ground and relatively
light winds, temperatures this morning across southeast texas are
expected to fall to 25-32 f, with the exception of the coastal
areas where winds remain over 10 mph. The current freeze line, as
of 3 am, is roughly along and north of a wharton-the woodlands-
livingston line, and is expected to progress farther south
throughout the early morning hours. Therefore, a freeze warning
remains in effect for the entire CWA except the barrier islands
until 9 am cst today. Wind chills will dip down to 20-25 for
interior southeast texas, so be sure to bundle up for the morning
commute or bus stop. Forecast low temperatures this morning are
within 1 or 2 degrees f of record low minimum temperature for all
of our major climate sites, so this cold spell may be record-
breaking cold, in addition to the record-setting earliest snowfall
yesterday. High temperatures will struggle to reach 50 this
afternoon, which is over 20 degrees below normal.

Strong cold air advection remains in place with continuing clear
skies and calmer winds, causing low temperatures tonight to dip
down once again below freezing. Neither a freeze watch or warning
is in place because of the current freeze warning. Any areas that
do not dip to or below freezing this morning and are expected to
reach freezing tonight will be added to an additional freeze
warning. The remainder of the week will stay cloud-free as the
surface high progresses eastward over the northern gulf. Without
the oppressive sinking air associated with high pressure systems,
temperatures will be able to gradually increase to seasonal
average by Saturday with highs near 70 and lows near 50.

Long term [Saturday through Wednesday night]...

onshore flow resumes late Saturday, resulting in an increase in
moisture and cloud cover. This moisture slightly builds up over
southeast texas just in time for a weak cold front to approach the
region from the northwest. Highest rain chances will be Sunday
night into Monday morning along and behind this anafront. Although
canadian in origin, the coldest air will remain north of the
area. Temperatures will still decrease Monday and Tuesday from
highs in the 70s to highs in the 60s, but nowhere near as cold as
we are currently experiencing.

Moderate northerly surface winds behind the front on Monday will
quickly veer to onshore on Tuesday, as a coastal trough builds
over the southwestern gulf. The associated moisture return will
result in an increase in pops Tuesday and Wednesday. An additional
"rain-maker" mid-week next week will be a cold front crossing
through texas on Wednesday and Thursday. While there is still
much uncertainty and a large model spread with timing and details
of the front, all show some disturbance progressing through
southeast texas around thanksgiving. For now, rain chances
increase heading into the holiday, making this the feature to
watch in the upcoming forecast.

22
marine...

there is a wide disparity between seas at the 42035 buoy and
offshore at 42019. 42035 showing 3 ft seas while 42019 showing 8
ft seas. Winds along the coast are borderline SCA while advisory
conditions are holding strong offshore. The current stair step
decrease in hazards for advisories looks on track as winds seas
should continue to decrease with high pressure at the surface over
the hill country. Exercise cautions may need to replace the
advisories at some point in the transition to lower winds seas for
this afternoon and tonight. Low winds and seas are expected
tomorrow and Friday. Southerly winds develop on Saturday with
another front pushing off the coast late Sunday into Monday.

Tide levels up in the houston ship channel of galveston bay and
closer to port lavaca in matagorda bay are increasing heading into
high tide this morning. Offshore winds will continue today so the
low water advisory will be needed for tides about 1 foot below
normal this evening with low tide.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
