(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus64 kcrp 180923 afdcrp area forecast discussion national weather service corpus christi tx 423 am cdt Thu jul 18 2019 Short term (today through Friday) No change to the semi-permanent upper pattern (ridge over the srn conus with disturbances moving around the NRN periphery of the ridge) during the period (gfs ECMWF nam deterministic output). Nam and GFS deterministic runs maintain pwat values below normal during the period. No significant pcpn expected. Expect maximum heat index values in the 105-109f range with isolated amounts around 110f over SRN sections. Long term (Friday night through Wednesday)... the 500mb sub-tropical ridge will remain in place through Saturday before starting to break down and shift northwest late this weekend. Above normal temperatures and generally dry conditions are expected through the weekend as limited moisture and subsidence continues. However, can not rule out an isolated shower or thunderstorm with the afternoon sea breeze. Breezy conditions will be possible Saturday afternoon as broad high pressure across the gulf of mexico and lower pressure upstream persist. The latest GFS and ecmwf continue to suggest a weak cold front will move south into central texas early next week before stalling across south texas by mid to late week. There remains some uncertainty on how far south this frontal boundary will make it. However, rain chances should begin to increase across the CWA by early next week. Southeast winds are |
expected to shift to the east with slightly cooler temperatures on Tuesday and Wednesday. Marine Anticipate small craft exercise caution conditions over the srn bays nearshore coastal waters this afternoon owing to the expected thermal mslp gradient. Application of local expert system suggests a moderate risk of rip currents today Friday. Small craft exercise caution conditions are possible Friday night into Saturday, mainly for the southern waters. Otherwise, weak to moderate onshore flow will prevail with seas 2 to 4 feet. Isolated to scattered thunderstorms over the waters Sunday through Tuesday.

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. |
