Aviation Showers and thunderstorms have already begun developing over the coastal waters. These will move over the coast this morning, introducing MVFR ceilings for vct. Light winds combined with higher moisture could allow for some patchy fog, particularly for ali and vct around daybreak. Isolated to scattered showers and thunderstorms are possible across the coastal bend and victoria crossroads this morning as convection moves ashore and again this afternoon along an enhanced seabreeze, so have added a mention of vcsh and vcts for crp, ali, and vct. Any thunderstorms that develop could cause gusty winds and reduced visibility. Prev discussion issued 413 am cdt Fri aug 23 2019 short term (today through Saturday)... upper level energy and associated tropical moisture continue to trend more toward the north, with most of the moisture remaining off the south texas coast. Showers and thunderstorms are likely over the waters, with a slight chance to chance of some morning convection across the coastal bend and victoria crossroads. A slight chance to chance of showers and thunderstorms will continue through the evening today and tomorrow, but development will be highly dependent on the seabreeze. Rain totals over the area will likely be low; however, with pwats near or over 2 inches, showers and storms that develop could provide quick downpours. Cloud cover will increase through today, particularly over the east, moderating temperatures a bit. This should keep us near normal for this time of year. With the fairly high humidity, heat index values will peak near 105 to 109, with some locations briefly reaching near 110. At this point, will hold off on a heat advisory as advisory criteria are not met consistently over any particular location, and the development of any showers or thunderstorms will likely inhibit higher heat index values. A similar situation is expected Saturday, with near normal temperatures, high humidity, increased cloud cover, and the possibility of showers. Long term (Saturday night through Thursday)... a mid-level shortwave will move east across the northern mexican |
state of chihuahua into texas around the big bend area through Saturday night, moving farther south toward south texas by Sunday night as the mid-level ridge remains situated across the desert southwest. This will bring additional moisture from the west, with pwats of 2.0 to 2.3 inches. With this amount of moisture being between the 75th percentile of normal moisture and +2sd above normal moisture, showers and thunderstorms will be possible. The main caveat will be the h925 and h85 temperatures which continue to run warm. With the exception of the more aggressive GFS model, other long term models hold back on convection. Will continue to follow a more persistent weather pattern with only isolated to scattered showers possible underneath the cap daily inland, especially during the overnight to early morning hours, with greatest rain chances over the gulf waters. Hot and humid conditions continue through the period, with highs across the coastal region in the 90s, and highs farther west across the rio grande plains up to 104 degrees. Heat index values over 105 degrees across for most locations across south texas, with heat advisories possible Monday through Thursday, especially across the southern coastal bend. Marine... a generally weak to moderate onshore flow will persist through early next week. Ample moisture across the area waters will contribute to scattered showers and thunderstorms across the middle texas coastal waters through the weekend. Moisture is expected to linger and contribute to isolated showers and thunderstorms next week. A more moderate onshore flow is expected during the afternoon and overnight periods across the waters Sunday through Monday night, especially for areas south of port aransas.

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. |
