950 pm cdt Sat apr 29 2017

Update
The rapid southeasterly advance of the cold front is certainly
doing a number on the (potential) convection this evening as it
undercuts the line. The boundary has passed across college station
at the bottom of the 8 pm hour with 9 pm pressure rises and a
stout NW 20 mph wind gusting to over 30 mph. Will give it another
20 minutes or so and then... If activity doesn't blossom up... Will
be paring back/canceling the severe watch at 10 pm (an hour early).

Per a recent uh sounding... The downstream is pretty capped between
7-850 mb so am not anticipating much more than the passage of
light showers between 10 and midnight over metro... The front
should be clearing the coast between 8 to 9z per recent 01z hrrr
run. Breezy northwesterlies under early Sunday clearing skies...

becoming mainly clear by early afternoon. Afternoon temperatures
will slowly warm into the average middle 70s as lower level cold
advection continues through sunset. Surface high moves over
tomorrow night... Weakens Sunday night/Monday morning variable
winds to near calm. Overnight resident dry air mass with dew
points in the 40s equates to Monday morning interior mints in the
upper 40s to lower 50s... Low to mid 60s along coast. 31
prev discussion... /issued 706 pm cdt Sat apr 29 2017/
.Severe thunderstorm watch is in effect for the northwestern
cwa through 11 pm tonight...

a severe thunderstorm watch is in effect for the northwestern
forecast area through 11 pm. The main threats in association with
the approaching cold front will be damaging thunderstorm winds
and hail. The strongest convection is expected to begin moving (or
developing) across the extreme northwestern counties from around
9 pm and be across the majority of the northern counties... Possibly
moving into the east-southeast cwa... Before midnight. 31
prev discussion... /issued 636 pm cdt Sat apr 29 2017/
aviation...

really not many changes to the ongoing tafs other than to slightly
tweak timing of, what's expected to be, a thin line of shra/tstms
that'll be moving thru SE tx later this evening and overnight
ahead of a cold front. Southerly winds should remain gusty into
the evening hours then gradually taper off ahead of the front.

Improving aviation conditions in its wake on Sunday. 47

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
