From KSFY Television Meteorologist Shawn Cable

Get ready for our first big summer heat wave! Heat and humidity will start to kick in today with a gradual increase in both as we get closer to the weekend. By Saturday, the heat index will likely reach 105 degrees or better across much of the region.

After an isolated morning thundershower, today will be partly cloudy with highs in the mid to upper 80s. You'll notice the humidity creeping up a bit this afternoon as the dew point rises into the mid to upper 60s.

Scattered thunderstorms are possible tonight and again tomorrow morning. Some storms could be strong to severe with wind and hail being the main threat.

By tomorrow afternoon, storms will be out and the sun will be in. While tomorrow's temps will be similar to today, the humidity will be a bit higher.

By Friday, we'll hit full-on summer heatwave mode and stay there through the weekend. High temps will be in the 90s throughout the weekend with the heat index soaring above 100 degrees each day. The warmest day of the weekend will be Saturday with highs in the mid to upper 90s and a heat index at or above 105 degrees. The weekend will be mostly sunny, but with the heat and humidity there could always be a random, isolated thunderstorm.

The heat and humidity will break a bit early next week. Monday and Tuesday will be partly cloudy with scattered thunderstorms and highs in the mid to upper 80s.
