Area Forecast Discussion . UPDATED National Weather Service Corpus Christi TX 609 PM CST Tue Dec 10 2019

DISCUSSION.

Updated for the 00Z Aviation Discussion.

AVIATION.

MVFR CIGs to persist tonight through 15-18Z WED with model soundings showing moisture trapped around 1500-2000 feet. Afterward, a transition to VFR is expected. Gusty northerly winds this evening will gradually diminish to 5-10 KTs overnight through much of the day WED, with a slight turn to the northeast late in the TAF period as high pressure builds into the region.

PREV DISCUSSION. /Issued 342 PM CST Tue Dec 10 2019/

SHORT TERM (Tonight through Wednesday night) .

Most of the rain associated with the cold front has come to end with showers lingering in the eastern portions of the CWA. Low temperatures tonight could dip to near freezing in the northern tier of counties, but generally expect temperatures to remain in the upper 30s to low 40s for most. Winds will continue to be gusty at least through the evening, so have kept the Wind Advisory in place across the coastal counties through 9 pm. The upper level system associated with this will move out of the area by Wednesday, leaving cool temperatures, diminished winds, and clearing skies.

LONG TERM (Thursday through Tuesday) .

The deterministic GFS, NAM, and ECMWF predict an upper disturbance to move across the CWA Thursday. In response, isolated showers are expected over the ERN CWA Thursday afternoon/evening, with moisture as the limiting factor (NAM/GFS predict PWAT values just below normal.) Another upper system is predicted to move across the NRN Plains/Great Lakes/Midwest Thursday night/Friday with the corresponding frontal boundary moving SWD across the Plains. This boundary is predicted to stall just north of the CWA Sunday, while another system approaches from the SRN Rockies. A wave also develops along the front. The combination of upper and surface forcing is expected to increase the chance for showers over the ERN CWA Sunday night/Monday. Drier Tuesday as the upper system moves east.

MARINE . A Gale Warning and Small Craft Advisory will remain in place through this evening with windy conditions. Winds will begin to diminish later this evening, however a Small Craft Advisory will be in effect from midnight tonight through Wednesday morning across the Offshore Waters as the upper level system moves offshore. Moderate north to northeasterly flow will continue Wednesday, diminishing to weak to moderate flow Wednesday night. Weak to moderate offshore flow Thursday then becoming light as the MSLP gradient weakens. Isolated showers Thursday evening in response to an upper disturbance. Another upper disturbance, and corresponding surface front/low pressure system is expected to increase the chance for showers Sunday night/Monday.

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.
