High pressure moving off to the east will allow onshore winds to return to the area Sunday night and strengthen on Monday. Moderate onshore winds and elevated seas can be expected for much of the remainder of the week.

Area Forecast Discussion National Weather Service Corpus Christi TX 1045 PM CST Sat Jan 16 2021

AVIATION /06Z TAFs/ .

VFR conditions are expected through most of the period. A shallow layer of moisture may result in brief borderline-MVFR visibilities as fog develops closer to sunrise across the Coastal Plains and the Brush Country. Light and variable winds will continue overnight with a brief shift to the north mid day as a weak boundary moves through the region. Southeasterly flow will return towards the end of the period with winds generally around 5 knots.

PREV DISCUSSION . /Issued 409 PM CST Sat Jan 16 2021/

SHORT TERM (Tonight through Sunday Night) .

GOES WV imagery depict an upper level disturbance approaching/entering TX from the NW. Concur with deterministic output that this upper system will move across the CWA tonight/Sunday. Although mid/upper level clouds will be associated with the ascent portion of the disturbance, below normal PWAT values (per the GFS/NAM) will preclude precipitation. Very low dew points this afternoon, along with the expectation of light wind overnight, would suggest strong radiational cooling. However, the cloud cover will limit cooling. Nevertheless, will forecast minimum temperatures closer to the NBM, which is cooler than the SREF ensemble mean temperatures at 12z Sunday. No freezing temperatures anticipated. There is a risk that patchy fog could occur tonight/early Sunday morning, when considering the NAM prediction of near saturation at the surface, yet very dry aloft. However, not confident enough to add fog. There is a slightly better chance for fog Sunday night (per SREF probability output), yet unsure whether the moisture depth will limit fog development.

LONG TERM (Monday through Saturday) .

Not much has changed from the previous forecast package. Models are continuing to show an area of low pressure developing across North Texas Monday. The area of low pressure is expected to move southward into Mexico with onshore flow increasing across the CWA. As a trough and associated low pressure approaches the region Tuesday, moisture is expected to increase across the Coastal Plans and Coastal Bend. PWATs are expected to be around 1.5 inches Tuesday night into Wednesday, and beginning to decrease slightly Thursday. Isolated showers are expected Tuesday, becoming scattered Tuesday night into Wednesday with rain chances beginning to decrease by Thursday. With uncertainty regarding the timing, models are showing the possibility of a weak front affecting South Texas Friday.

High temperatures Monday through Wednesday are expected to range within the lower to upper 70s before increasing a couple degrees into the mid 70s to lower 80s Thursday ahead of the possible weak front. Low temperatures will remain mild Monday through Thursday night with temperatures in the 60s and dropping about 5 degrees into the mid to upper 50s Friday night if the front has enough energy to push through South Texas.

MARINE .

Weak onshore flow expected tonight through Sunday night. A weak to moderate southeast flow on Monday will become strong Monday night over the Gulf waters with Small Craft Advisory conditions Monday night into Tuesday morning. Small Craft Exercise Caution conditions will continue in the wake of the Small Craft Advisory with Small Craft Advisory condition possible again Wednesday night into Thursday night. Winds will subside to moderate levels from the southeast by Tuesday night continuing into Wednesday. Isolated to scattered showers will be possible over the area Tuesday and Tuesday night with rain chances decreasing by Thursday night. An isolated thunderstorm cannot be ruled out.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
