Marine Weather and Tide Forecast for Heath, TX

SHORT TERM
(This afternoon through Saturday)
Issued at 146 PM CDT Fri Mar 13 2026

Expect an overall tranquil and warm transition from the work week into the weekend, with abnormally warm temperatures and southerly winds persisting through tomorrow. A surface low is currently moving south into the Permian Basin. While southerly winds and mostly sunny skies allow for warming temperatures across the region, the movement of the low to our west will add somewhat of a southwesterly wind component to our Big Country counties this afternoon. In response to this downsloping wind, temperatures should be able to rise a couple of degrees warmer than the NBM, and we have increased high temperatures slightly due to this.
Expect highs in the mid 70s to mid 80s. Saturday will be another warm and sunny day with highs in the upper 70s to upper 80s. Wind speeds and gusts will begin to gradually increase throughout the day tomorrow in response to an incoming mid-level disturbance from the PACNW and a deepening lee-side surface low to our northwest.
By Saturday afternoon, expect winds around 15-20 mph with gusts closer to 25-30 mph.

LONG TERM
(Saturday night through next Thursday)
Issued at 146 PM CDT Fri Mar 13 2026

The aforementioned shortwave and surface low will move east into the Central Plains by early Sunday morning, with breezy winds continuing ahead of the system. Throughout Sunday morning, expect winds 15-25 mph with gusts up to 30-35 mph. As the disturbance and low move, they will shunt the system's strong cold front southward towards North and Central Texas. This front is progged to reach our northwestern counties by 12-1PM, but could reasonably be a couple hours earlier (RAP has the front reaching our northwest closer to 10 AM). We'll nail down this timing better over the next day or so as it begins to be within the high- resolution guidance window. A lack of moisture ahead of the front means that this FROPA will remain dry for most, however there remains low chances that more abundant moisture pools out in East Texas near the front as it moves south. This would allow for scattered showers and storms to develop and grow upscale into a line(s) along the front in our East and southeast Central Texas counties Sunday afternoon and evening. Convective development would be conditional on if quality moisture is able to interact with the lift from the front within our CWA If storms are able to develop, model soundings show that enough shear and instability would be present for a couple strong to severe storms with a primary wind threat.

The bigger story will be what occurs behind the front Sunday into Monday. While conditions will be breezy ahead of the front, winds within the post-frontal airmass will be downright windy, with speeds increasing to 30-35 mph sustained and gusts between 40-50 mph by the afternoon. Over the next day or so, we will be issuing a Wind Advisory for most (if not all) of our North and Central Texas counties. We will approach our High Wind Warning criteria in some spots (sustained 40+ mph / gusts 58+ mph), but it is uncertain at this time whether or not we would exceed that criteria and just how widespread these more extreme winds would be. Nonetheless, make sure to secure/bring in any loose outdoor items and be very cautious driving on W-E roads on Sunday. These strong winds will aid in an elevated to critical fire weather threat for Sunday for areas near and west of I-35, as highs will be above normal for the day and humidity will drop below 30%. Even with the recent rainfall, we are still fairly dry and available fuels are within the 60-70th percentile.

As the front moves south, strong post-frontal north winds and stout CAA will allow for falling temperatures behind the front.
While high temperatures for Sunday are expected to be in the 70s and 80s, by mid-late evening, temperatures will have dropped into the 40s and 50s. A late season freeze is on the books for portions of North Texas and the Big Country as overnight temperatures are able to dip into the upper 20s to low 30s Monday morning, with elsewhere dropping into the mid 30s. Much cooler conditions will persist through Monday as highs only peak in the 40s and 50s, alongside another night of lows in the 30s (some areas in East Texas dipping below freezing). Behind the departing shortwave disturbance, upper-level ridging will begin to build back into the region, and with the return of southerly winds, will allow for a warming trend as we head into mid-late week.

AVIATION
(00Z TAFS)
Issued at 558 PM CDT Fri Mar 13 2026

VFR skies with a modest southerly breeze of 10-15 kts will prevail the rest of this evening and tonight. An influx of low stratus could result in MVFR conditions at Waco towards daybreak Saturday, and a Tempo has been introduced for cigs near 1 kft.
Veered flow will likely keep the bulk of this cloud cover east of Metroplex TAF sites, although stratus of FEW/SCT coverage could pass near the eastern airports of DFW, GKY, and DAL. Stronger south winds are forecast tomorrow afternoon and evening, and gusts near or above 25 kts can be expected through the end of the forecast period.
