Area Forecast Discussion National Weather Service Corpus Christi TX 352pm CST Thu Nov 14 2019 Short Term - Tonight Through Friday Night Satellite imagery shows the weakening upper low east of Matagorda Bay moving to the east. Some lingering light showers or areas of light drizzle will affect the coastal region early this evening. But drier air will finally push into south Texas tonight with skies clearing late tonight. With clearing skies inland, should see lows in the upper 30s across the northern counties. The gradient will be strong enough along the coast for breezy conditions for the island this evening as high pressure builds into south Texas. Dry conditions and mild temperatures are expected for Friday under mostly sunny skies. A cool night is in store for Friday night as the high pressure ridge settles over south Texas with lows in the mid to upper 30s. Tide levels continue to run a little over a foot above expected levels at Bob Hall Pier and Port Aransas. This will lead to minor coastal flooding around time of high tide this evening. Adjusted the expiration until 06Z for possibility of flooding lingering for a few more hours past high tide. P-ETSS continues to show the tide levels will remain elevated through Friday with minor coastal flooding expected again around the time of the next high tide cycle late Friday afternoon and evening. Long Term - Saturday through Thursday Warming trend expected through the weekend as midlevel ridging builds in from the southwest, with highs reaching into the 60s and 70s. Onshore flow returns at the surface on Saturday and Sunday as surface high pressure slides off to the east and an area of low pressure develops across the Texas Panhandle. In the meantime, a longwave trough will dig through the Great Plains Saturday and Sunday, pushing a weak cold front through South Texas Sunday night into early Monday morning. Moisture should be sufficient enough for isolated showers along the boundary, but mainly be confined across the coastal region and across the gulf waters. An uptick in the winds is expected over the waters Monday, but Small Craft Advisories are not expected. Temperatures will not be greatly affected with the frontal boundary, however relatively humidity values in the afternoon will be noticeably lower. Surface high pressure will build in on Monday, with a second weak reinforcement high on Tuesday, keeping things dry. Winds return out of the southeast Tuesday night as the surface high quickly slides east. Onshore flow will strengthen on Wednesday and Thursday as surface low pressure again develops near the Texas Panhandle. Breezy conditions are expected over land, but Small Craft Advisories will be possible for portions of the gulf waters. This should help return at least slight chances for rain for the latter half of next week. Marine Scattered showers and areas of light drizzle will linger over the coastal waters into the evening hours then diminish overnight as the weakening upper low/trough moves to the east. The gradient will increase tonight between the area of low pressure over the northwest Gulf of Mexico and high pressure building into south Texas. Moderate to strong north winds will occur tonight through early Friday morning. Winds are expected to diminish along the coast late and will expire the SCA (Small Craft Advisory) for the near shore waters at 10Z. The SCA (Small Craft Advisory) will linger until 18Z Friday even though the winds will have diminished below criteria early, the seas will likely remain elevated most of the morning. A weak to moderate offshore flow is expected for Friday night. A weak onshore flow will develop Saturday night and Sunday as surface high pressure slides east and low pressure develops in the Texas Panhandle. A weak cold front will move off the Coast Sunday Night resulting in a weak to moderate offshore flow. Isolated showers will be possible along the front. Offshore winds will become weak and variable Monday night and Tuesday, then become more onshore Tuesday night. Small Craft Advisories may be needed for portions of the gulf waters Wednesday and Thursday as another area of low pressure develops near the Texas Panhandle.
