Aviation
Based on slowly increasing ceilings, model soundings time heights,
and trends, it appears that conditions will improve (no wintry
precip) at kvct and klrd by 16 23z, then kali and kcrp at 02z and
03z respectively. Concurrently, these terminals will begin to see
improved CIGS during that time, as the isentropic pattern
diminishes ends. Since precipitation is more scattered now, will
go with tempo groups rather than categorical. Since temperatures
are just about freezing now if not below, have zr with pl in the
terminals. Winds will taper off as CIGS improve as mentioned
before, withVFR conditions at kvct around 17 00z (klrd about the
same time), then kali AOA 17 02z and kcrp 17 03z. Should stayVFR
after that. North winds will generally continue to decrease
through the period, with no precipitation expected as drier air
comes in.

Previous discussion issued 1130 am cst Tue jan 16 2018
discussion... Freezing line continues to shift south this morning
and nearly all of S tx should be below freezing by early afternoon.

Areas of light rain light drizzle continue across the southern
portions of the CWA with light freezing rain freezing drizzle
mixed with sleet occurring across the far western and northern
half of S tx. Expect most areas to transition to periods of light
freezing rain drizzle and light sleet through the afternoon... With
possibly a transition to all sleet occurring by mid to late
afternoon as the sfc-h9 layer cools further.

The back edge of light precip should begin to progress from NW to
se by early to mid afternoon as drier air works its way into the
aforementioned sfc-h9 layer. Guidance continues to trend faster
with this occurrence... And as such precip should end earlier this
evening than previously forecast. Therefore, the expiration time
of the winter weather advisory has been changed to this evening
(rather than late tonight).

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.
