Area Forecast Discussion . UPDATED National Weather Service Brownsville TX 1138 PM CST Thu Dec 12 2019

DISCUSSION. Updated for latest aviation discussion below.

AVIATION. Surface high pressure will continue to settle over the region tonight with clear skies in place. This will combine with a relatively dry layer in the low levels, resulting in the development of fog overnight. Dense fog will be possible, especially in the lower RGV from BRO to HRL, before sunrise. Therefore, a period of IFR to LIFR visibilities continue to be possible. By mid-morning, conditions will improve and VFR conditions should prevail.

PREV DISCUSSION. /issued 629 PM CST Thu Dec 12 2019/

DISCUSSION . Made an adjustment to the forecast this evening to include areas of fog across all inland locations tonight into Friday morning. Winds have already begun to calm in the Mid Valley as surface high pressure settles over the region. In addition, very dry air will advect into the region in the low levels, moving over a relatively moist surface. The current limiting factor for sufficient radiational cooling is a thick cirrus layer blanketing the eastern half of the CWA. This is expected to clear out from west to east late this evening, allowing dew point depressions to fall. There is the possibility of dense fog, which is particularly noted in the latest SREF guidance.

This will combine with a relatively dry layer in the low levels, resulting in the development of fog overnight.

PREV DISCUSSION . /issued 249 PM CST Thu Dec 12 2019/

SHORT TERM (Tonight through Friday Night): Cool, though near normal weather will continue tonight in a benign pattern with light winds and low temperatures in the 40s and 50s. Patchy fog likely will develop across the area, with patches of locally dense fog possible. Temperatures will warm to near or slightly above normal on Friday, in the 70s to lower 80s, with upper 40s to lower or mid 50s Friday night. Weak coastal troughing will persist tonight before breaking down on Friday. A weak mid level trough axis will lift over Texas and will be replaced by a stable northwest mid level flow and lower column moisture. Winds will remain light, shifting to southwest Friday to Friday night. This will help support the warmer Friday temperatures, and later on Saturday. Low level moisture will recover along with temperatures, and patchy fog could again develop Friday night. Overall, however, quiet weather will prevail with negligible rain chances as high pressure dominates over the region.

LONG TERM (Saturday through Thursday): The global models are in good agreement with the upper air patten across the United States Saturday with a 500mb trough across the eastern United States and a west to northwest flow aloft across south Texas. Low to mid level moisture will be limited across southwest TX through the weekend into early next even as a 500mb trough develops across the west-central U.S. Monday and moves eastward Tuesday. This upper level trough will bring a cold front through the Rio Grande Valley early Mon night and a chance of showers mainly across the coastal sections Mon afternoon into Mon evening. High temperatures will generally be in the 80s Saturday through Monday before cooler air advects into the area Mon night into Tuesday. Temperatures will be below normal through the rest of the forecast period with dry conditions as surface high pressure settles into the state Wednesday and shifts eastward Thursday.

MARINE (Tonight through Friday night): Lingering high seas prevail offshore at Buoy020, but conditions are slowly improving. Should be able to drop the small craft advisory later today. Winds and seas will further decrease through Friday night as broad high pressure remains over the northwest Gulf.

Saturday through Tuesday . Light south to southwest winds will prevail across the coastal waters Saturday with surface low pressure across west Texas. Winds will increase Sat night as the pressure gradient increases across the lower Texas coast. Moderate to strong south winds will develop offshore the lower Texas coast providing at least SCEC conditions if not SCA conditions. Small craft advisories will likely be needed for the coastal waters Sunday as strong south winds develop across the lower Texas coast. Winds will diminish Monday as the pressure gradient weakens ahead of a cold front moving into south Texas. The front will move through the coastal waters Mon night and very strong north to northeast winds will develop with gusts near gale force likely. Strong north winds will prevail across the lower Texas Tuesday in the wake of the cold front. Gale warnings may be needed for the offshore waters Mon night into Tues morning Otherwise. small craft advisories will be needed for all of the coastal waters Mon night into Tuesday.

BRO WATCHES/WARNINGS/ADVISORIES. TX . None. GM . None.

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