Area Forecast Discussion . UPDATED National Weather Service Corpus Christi TX 628 AM CDT Fri Aug 14 2020

DISCUSSION. Inserted patchy fog over Jim Wells and Duval Counties early this morning. See Aviation section for 12Z TAFs.

AVIATION. Low stratus and fog has formed in the region between ALI and HBV with IFR ceilings and LIFR vsbys. Expect this area of fog and stratus will lift by 14Z. Elsewhere, VFR conditions will occur today through the evening hours. Patchy fog will be possible after 09Z Saturday for the inland coastal plains with MVFR vsbys expected at this time. Light south winds will increase to southeast by this afternoon and become a little gusty over the Coastal Bend.

PREV DISCUSSION. /Issued 342 AM CDT Fri Aug 14 2020/

SHORT TERM (Today through Saturday) .

Hot and dry conditions will continue through the period as the mid to upper level ridge will remain over the southern Rockies east into central and south Texas. Moisture levels will be below average with precipitable water values below 1.5 inches today with GFS/NAM showing a very slight increase in PW values for Saturday. Expect dewpoint temperatures will fall to similar values this afternoon as yesterday during daytime mixing. Afternoon heat index values should remain below advisory criteria although some locations over the inland Coastal Bend could reach 110 for a brief period. Values should be a little higher on Saturday as dewpoints not expected to fall quite as much and high temperatures to be just a little higher. So may need an advisory for Saturday afternoon across the inland coastal plains.

LONG TERM (Saturday Night through Thursday) .

After one more day of very hot and dry conditions across South Texas on Sunday, the pattern aloft becomes a bit more unsettle as we head into next week. The mid to upper level ridge that has dominated the local weather for the past several days will be shifting westward in response to a trough deepening to the southeast into the northwestern Gulf coast. The weakness in the ridge will allow for a series of weak upper level disturbances to track into the area throughout the period. This will lead to increased instability across the region, which could combine with the arrival of deeper moisture to produce isolated to scattered convection beginning on Sunday night. As per current guidance, the best rain chances will exist Monday through Tuesday when a very weak frontal boundary is expected to drift south into our area allowing for the convective activity to become more scattered. The pattern aloft will vary very little throughout the remainder of the week, therefore have maintained isolated rain/storm chances in the forecast through Thursday mainly for sea breeze induced activity. However, models have trended drier leading into the mid and latter part of the week with PWATs dropping to well below normal for the season (around 1.3- 1.4 inches), so for now went close to NBM but may have to adjust PoPs in following packages.

Heat indices will continue to be a safety concern during the afternoon hours Sunday through Monday, with values approaching or exceeding 105-109 degrees. Some locations may experience values of 110 degrees or more at times on Sunday, and a Heat Advisory may be required later on. Temperatures are expected to return to near normal values Tuesday through Thursday due to the arrival of the rain.

MARINE .

A weak to moderate onshore flow will occur over the region through the period, except for late afternoon into early evening period when thermal gradient will lead to moderate southeast winds over the bays and near shore waters south of Port Aransas.

A weak to moderate onshore flow will continue through the weekend. During this time, brief moderate onshore winds will occur in the afternoons across the bays and nearshore waters, mainly south of Port Aransas. The arrival of a weak frontal boundary may lead to isolated showers and thunderstorms Monday through Tuesday, along with a weak offshore flow. Convective chances will continue daily through the latter part of the week.

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.
