Tonight will be muggy with low clouds and fog. The fog won't be as dense at the coast due to the breeze staying up near 10 mph but inland areas will see areas of dense fog with light winds. Low temperatures will fall into the upper 50s to low 60s by morning.
A cold front will arrive Wednesday afternoon with widely scattered showers. We'll still warm up into the middle 70s with south winds before the front arrives and cools temperatures down with northwesterly winds. Rainfall will be spotty with highest totals north of Corpus Christi where up to a quarter inch is possible but areas south will only see a tenth or less.
Thursday and Friday look pleasant with cool mornings and mild afternoons and mostly sunny skies. Highs will reach into the upper 60s Thursday and mid 60s Friday. Expect a cold morning Friday with lows in the upper 30s and 40s.
The clouds increase again Saturday ahead of another cold front that will move through South Texas on Sunday around midday with another shot at a few showers. Winds will be gusty with the Sunday cold front and send temperatures to the 30s by Monday morning.
