CORPUS CHRISTI, Texas — Upper level high pressure that gave fair but hot conditions over the weekend will shift into the Central Plains States early in the week, allowing deeper tropical moisture into the region from the western Gulf of Mexico.
By midweek, that moisture will combine with weak instability to bring isolated coastal showers. Rainfall totals will be modest, and temperatures will stay at or slightly below normal for this time of year.
Heat index values each afternoon, however, will reach between 105 and 109 degrees. The tropical Atlantic Basin remains no threat to the Coastal Bend.
