Aviation Vfr will again be the prevailing conditions for the period, with the possibility of some MVFR cig vsby in the morning hours. Confidence in this is low in vct and crp, so left the mention out of those tafs, but did include this in the ali TAF as confidence is a bit higher. Winds will likely remain light to moderate for the majority of the period with winds slightly stronger than usual for much of the period, particularly along the coastal bend and coastal plains. Precipitation is not a factor for the area tonight through Sunday, with very little chance of showers or thunderstorms over land. Prev discussion issued 350 pm cdt Sat aug 17 2019 short term (tonight through Sunday night)... midlevel ridge situated across texas will continue hot conditions through the weekend. Moisture in the lower levels will continue humid conditions at the surface, as well as slight chances for showers to develop mainly across the gulf waters during the overnight and early morning periods. Heat indices over 100f degrees are expected across south texas, with a heat advisory currently in place for the southern coastal bend this afternoon. Will likely see another heat advisory for Sunday, although there may be a bit more coverage than today. The only relief will be the breezy conditions that develop in the afternoon as the thermal gradient sets up. Small craft exercise headlines will remain in place for portions of the bays and gulf waters, especially for areas south of port aransas, as moderate onshore flow develops this afternoon due to the thermal gradient and then overnight from mixing with the low level jet. Overnight lows will continue to run above seasonal normal with lows in the upper 70s across much of the inland areas to low to mid 80s. Along the coast and rio grande. |
Long term (Monday through Saturday)... the upper ridge is expected to gradually move westward during the period, resulting in a weakening of the upper geopotential height field over the ern CWA msa. The GFS and ECMWF deterministic predict greater moisture to advect onshore early in the period, with pwat values above normal over the ERN cwa. Deterministic and ensemble output suggest that a surface trough will enter the bay of campeche Tuesday Wednesday and influence the msa Thursday Friday. Anticipate that the combination of even greater moisture surface trough will contribute to scattered convection Friday Saturday. Expect maximum heat index values to fall below advisory criterion by Tuesday. Marine... hot and mostly dry conditions are expected across the middle texas coastal waters Sunday. A few streamer showers will be possible tonight and then again Sunday night across the gulf waters. Moderate onshore flow is expected tonight through Sunday night with small craft exercise caution headlines in place for the bays and gulf waters, especially for areas south of port aransas. Increasing moisture and weakening upper geopotential heights will contribute to isolated scattered convection during the period, with the greatest probability Friday Saturday owing to greater moisture proximity of a surface trough. Persistent onshore flow during the period, owing to a surface ridge over the NRN gulf of mexico surface low over west texas Monday Tuesday, and due to the proximity of the surface trough higher surface pressure to to the n NE afterward.

I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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. |
