CORPUS CHRISTI, Texas — A weak dome of high pressure at the surface will combine with an upper level ridge to give a gradually warming, fair weather scenario for the first half of this week, while upper level disturbances suggest isolated showers Friday and again on Sunday. No significant rainfall is expected either day.

The dome of surface high pressure is gradually moving east, and as it moves into the western Gulf of Mexico it will return higher levels of humidity on southeast winds. That increased moisture content will support isolated showers with a cold front on Friday, but the front's associated upper level disturbance will not be strong enough to generate significant rainfall.

A second disturbance arrives Sunday and will support isolated showers as well.
Highs in the 70s through this week will dip into the 60s Sunday and Monday. Lows will hover in the 40s and 50s, except middle 60s Friday morning.
