Wesley's Blog: Brink of dangerous heat

This weekend will bring some of this summer’s hottest weather to South Mississippi. Parts of the southeast were under a Heat Advisory through Saturday evening. 

As of July 11th, the Gulfport/Biloxi airport's hottest 2015 temperature is 94°. That 94° occurred in June. And this weekend we will see high temperatures in the lower to middle 90s.

This hot weather pattern is thanks to an upper ridge of high pressure that is moving in from the east. That ridge will bring a lot of warm, sinking air to the south US over the next several days. That sinking air will also help to prevent thunderstorm development in our area. So, any heat relief from passing showers will be brief.

Even though the temperature on the thermometer will read lower 90s, it will actually feel hotter when you factor in the humidity. That’s called the heat index or “feels like” temperature. And this weekend, it will feel like about 100° to 105° across much of South Mississippi for the entire afternoon. That’s on the brink of dangerous heat.

When the heat index is expected to reach 108° or higher (or the air temperature is expected to reach 103° or higher) the National Weather Service will typically issue a Heat Advisory. We won't have any triple-digit air temperatures in South Mississippi this weekend. But, due to the high humidity, the heat index will come pretty close to 108° in a few spots on Saturday and Sunday.

Unfortunately, as the upper ridge parks itself over the South, this hot weather pattern will continue into much of next week with little change expected. It’s always important to remember to stay hydrated. You can check out this blog for some hot weather safety tips.

For the record, the last time Gulfport’s temperature reached 100° was 2012; Biloxi's most recent triple-digit day (101°) occurred last August.
