Marine Weather and Tide Forecast for Trinidad, TX

SHORT TERM
(Tonight through Wednesday)
Issued at 145 AM CST Mon Jan 19 2026

A chilly night is unfolding across the region in the wake of yesterday's cold front, with temperatures expected to bottom out in the 20s to mid 30s by daybreak. Wind speeds will gradually decrease through the remainder of the night, so wind chills will remain within a couple degrees or so of actual temperatures.
Nonetheless, you'll certainly want to bundle up before heading out the door this morning! Cool but seasonable weather will prevail throughout the day today, with afternoon highs in the mid 50s to low 60s.

Southerly low-level winds will return to the region later this morning as a shortwave trough approaches. As a result, moisture will steadily increase this afternoon through Tuesday night. A weak cold front will be nearing our northern border early Wednesday morning. Ahead of the front, strengthening warm air advection will result in the development of scattered showers Tuesday night into Wednesday morning. Showers will increase in coverage as the front approaches and eventually moves through the area on Wednesday. Rainfall rates are expected to remain rather light, with only a low potential for thunder in Central Texas. The bulk of the rain chances will be confined to areas along and east of I-35, tapering off from west to east with the passage of the front throughout the day.

LONG TERM
(Wednesday night through next Monday)
Issued at 145 AM CST Mon Jan 19 2026

Wednesday's cold front will have little effect on our sensible weather, other than to shave a couple degrees off of high temperatures on Thursday, mainly across North Texas. Expect afternoon highs ranging from the mid 50s near the Red River to mid 60s in Central Texas.

Big changes will be on the way as we head into Friday, as a very strong cold front will move into the region from Oklahoma as early as late Thursday night/early Friday morning. As the front enters the area, overrunning is expected to quickly develop as the first of several shortwaves moves overhead. This will result in the development of widespread precipitation early Friday morning which will continue throughout the day. At this time, it still looks like temperatures will remain well above freezing for much of the day, keeping any precipitation in liquid form. This will change as we get later into the day, with frozen precipitation becoming increasingly likely heading into the evening/overnight hours Friday night as temperatures fall below freezing. The precise timing of this transition remains uncertain since we are still several days out. While latest guidance still indicates the transition to frozen precipitation will most likely occur after sunset Friday evening, there remains a low potential for an earlier transition Friday afternoon/evening, which could impact the evening commute. This will certainly be an important detail to monitor over the next few days.

As we head into the Friday night/Saturday time period, confidence in the potential for wintry weather and associated impacts across the region continues to increase. Widespread wintry precipitation is expected to develop Friday night into Saturday morning, as temperatures are forecast to bottom out in the teens to mid 20s for most of the area. Impacts to roads and infrastructure will likely begin Friday night, especially across North Texas where temperatures will be coldest. Conditions are not expected to improve much on Saturday and could continue to deteriorate throughout the day, as most locations will not see temperatures climb above freezing with additional rounds of precipitation expected to develop. Precipitation type currently looks to be a bit messy, as a warm nose is expected to exist just above the surface. This will likely result in a wintry mix for most of the area, with a transition to snow likely occurring somewhere near/north of the Highway 380 corridor. Precise amounts for any snow and/or ice accumulations are still too uncertain to pinpoint this far out since the location of any transition zones will ultimately determine these details. Therefore, be cautious with any accumulation information and precipitation type forecasts, as these details are certainly still subject to see significant changes over the next few days.

Any wintry precipitation should gradually taper off Saturday afternoon, though some of the latest guidance carries some low chances for additional wintry precipitation through Saturday night. By Sunday, no precipitation is expected, but very cold temperatures will certainly be a concern. Overnight lows are expected to plummet into the teens for most areas Saturday night, with our northwestern zones likely seeing lows in the single digits. A steady north breeze will result in wind chills near zero Sunday morning. Any winter weather impacts will likely linger into Sunday, with temperatures only forecast to reach into the low to mid 30s at this time. Fortunately, we should at least have some sunshine to assist with thawing out any lingering snow and/or ice, but any liquid left on the roadways at the end of the day will have a high likelihood of refreezing Sunday night, potentially resulting in impacts to the Monday morning commute.

Given the expected cold and potential for wintry weather, stay weather aware and up-to-date with the latest forecast this week as many of the forecast details will likely change over the next few days.
