MEMPHIS, TN (WMC) - The hot summer months are here, and this weekend the Mid-South will experience its first triple-digit heat index.

Saturday is a First Alert Weather Day because the heat index could reach 105 degrees and the evening will bring strong storms to the area.

With ample sunshine and a strong southwest wind, we will have the hottest day of the year to date Saturday. High temperatures on Saturday will be in the mid 90s and heat index values will reach 105 degrees.

The majority of the day on Saturday will be dry, but a cold front will bring rain late that night. Due to the high heat and humidity earlier in the day, this front will be moving into an unstable air mass--which could create some significant storms.

TIMING: Rain will start in Dyer County around 9 p.m. and then push south into Shelby County by 10 p.m. Showers and storms will continue in north Mississippi through midnight. Although a few light showers will linger before sunrise Sunday, everything will be clear by late morning.

THREATS: The primary threats will be hail and damaging wind gusts up to 60 mph. The strongest winds will be along the leading edge of the line of rain. There will also be a threat for heavy rain and frequent lightning.

Meanwhile, Methodist South Hospital's Director of Emergency Services said his hospital is beefing up staffing to handle any increase in heat-related illnesses.

"We look for people coming in with extreme nausea [and vomiting]--the ones that have worked in construction or outside all day," Brandon Bougard said. "I staff up more in the summertime especially on the weekend to make sure we have appropriate staff to take care of patient volume."

Heat exhaustion is the precursor to the more serious and life threatening condition of heat stroke.

"If you start experiencing cramps, nauseous, not feeling good overheated body, go somewhere and sit down. Get something to drink and get cool. But if symptoms don't resolve for you go on and come to the nearest ER," nurse Marquita Williams said.

Heat-related illnesses can strike anyone, but the elderly are most at risk.

"Take it slow and hydrate. Lots of water lots of Gatorade. Eight cups of water a day, we say, 12 in the summertime, because your body loses a lot of water with sweating," Bougard said.
