Area Forecast Discussion

.DISCUSSION...
A heat advisory is in effect for portions of SE Texas through 7 PM
this afternoon. Several obs are coming in at or above 108 within
the advisory area, and the breezy onshore winds are not causing
the dew points to mix out as much as initially anticipated. A
handful of showers and thunderstorms have developed across the
southeastern portion of the area this afternoon, and this activity
will likely continue through this evening.

Otherwise, a typical summer-like pattern will continue through the
period. Ridging overhead will allow high temperatures to rise well
into the 90s with heat indices generally in the 104-109 degree
range each afternoon. Like today, a heat advisory may be required
at times over the next several days. Isolated showers and
thunderstorms will continue to be possible each afternoon, with
some small variations in coverage and location depending on slight
differences in the upper-level pattern each day. The upper-level
ridge loosens its grip somewhat heading into next week, cooling
temperatures down just a touch and allowing for slightly higher
rain chances to start out the work week.  11

.MARINE...
Moderate onshore winds (occasionally strong during the
overnight hours) and elevated seas will continue into
Thursday. By the end of the week and on into the start
of next week, expect lighter winds and lower seas as
Gulf of Mexico high pressure edges closer to our area.
