Synopsis for Baffin Bay to Rio Grande out 60 nm: GMZ100
340 AM CST Tue Mar 2 2021

Improving, but still adverse, marine conditions are expected along the Lower Texas Coast today and tonight as surface high pressure gradually builds in from the west in the wake of the Monday passage of a cold front. More favorable winds and seas will then prevail until the end of the week, when another cold front brings increasing winds and building seas at that time and into the weekend.

Short Term - Now through Wednesday
Light precipitation is currently spreading over the central and eastern inland portions of the BRO CWFA and adjacent coastal waters with a cold front positioned over the western Gulf of Mexico. The precipitation should end by around sunrise this morning as closed 500 mb low pressure quickly shifts east to the Mississippi River Valley and surface high pressure builds in, allowing dry weather to prevail for the remainder of the period. Moderating temperatures are also anticipated as decreasing cloud cover allows for increasing sunshine.

Long Term - Wednesday Night through Monday
Surface high pressure across east Texas Wednesday night will move farther eastward Thursday into Thursday night. Temperatures will gradually warm Wednesday night into Friday as onshore surface flow develops. Low temperatures Wednesday night will fall into the 50s under partly cloudy skies. Thursday will be warm with highs in the 70s, the lower 80s across the west, with a mix of sun and clouds. A few showers will be possible on Friday as low level moisture increases along the lower Texas coast with the steady southeasterly flow. The next cold front moves across Texas on Friday and pushes through deep south Texas by Friday evening. Temperatures are expected to fall to near or slightly below normal in the wake of the front.

.Marine - Now through Wednesday
Adverse marine conditions will continue along the Lower Texas Coast until around sunset today with Small Craft Advisories in effect. Winds and seas will improve tonight and especially on Wednesday as high pressure becomes the dominant weather force over the region. However, seas may remain high enough tonight to warrant Small Craft Exercise Caution for the Gulf of Mexico waters from 20 to 60 nautical miles offshore.

Wednesday night through Saturday night...Favorable conditions are expected Wednesday night into Friday as high pressure prevails across the northwest Gulf. Light to moderate southerly flow and low to moderate seas will continue through Friday morning. The next cold front is expected to arrive by late Friday. Adverse conditions will develop in the wake of the front with moderate to strong north winds and building seas. A small craft advisory will likely be needed along the lower Texas coastal waters Saturday into Saturday night.
