Heat Advisory Again Monday

Another hot one today, with heat index values surging into the Heat Advisory range again. The advisory will be in effect from noon to 8pm with afternoon temperatures in the mid 90s from I-10 southward to the Gulf of Mexico, and mid to upper 90s north of the interstate. Heat index values will run from 105-110, with a few areas up to 113 over northern sections. There is a "front" in the region and it will bring a slight bit of relief on Tuesday.

The front may bring a few widely scattered afternoon showers and storms. Best chances for rain will be over the eastern sections. As the front sinks southward toward the Gulf of Mexico overnight, dew points will drop into the upper 60s to near 70 degrees. Not exactly the dry air we would like to see (as in fall like), but it will be considerably less humid. So, the steam bath type weather we’ve felt over the past few days will be more like a blast furnace! Even though the heat will be dry, it still will be very hot with highs in the mid 90s into the mid week. A slightly better chance for rain will come in later in the week and toward the weekend. Therefore, afternoon highs will run more in the normal range with low 90s during the day and mid 70s at night. 

At least tropical weather remains quiet. No new systems are expected to develop over the next several days.
