Marine Weather and Tide Forecast for Port Arthur, TX

SHORT TERM
(Tonight through Tuesday night)
Issued at 309 PM CDT Sun Apr 20 2025

Widely scattered to scattered showers were seen today in locations mainly north of the I-10 corridor. Temperatures were in the lower 80s and winds were out of the south, gusting mainly in the 25 to 35 mph range.

A cold front is located north to south across Texas, and it will approach our region late tonight into Monday. However, it never makes it past us, and in fact, actually backs up to our north as a warm front later on Monday night. What this means is we will not see as much rain as initially thought for tonight through Monday, with south central Louisiana seeing less than a tenth of an inch, and parts of southeast Texas and central Louisiana seeing maybe an inch or so. The severe storm threat looks low as well.

We will still see the southerly flow on Tuesday, so still expecting scattered showers and maybe a thunderstorm, but rain totals will be on the low side, less than half an inch. No severe storms are expected.

Temperature-wise, we will run a few degrees above normal for the highs - in the lower 80s, with overnight lows in the mid to upper 60s - around 10 degrees above normal.

LONG TERM
(Wednesday through next Saturday)
Issued at 309 PM CDT Sun Apr 20 2025

Wednesday looks like the wettest day of the week, with rain totals ranging from half an inch in south central Louisiana, to over an inch in southeast Texas. So far not expecting severe storms, but WPC does highlight southeast Texas and western Louisiana in a slight risk for heavy rain/flash flooding.

The trend for the remainder of the week is going drier and warmer.
By Saturday no rain is expected, and high temperatures will be in the mid to upper 80s.
