**Heat Advisory in effect for most of the viewing area until 8:00 pm**
The First Warning Storm Team is tracking triple digit heat and showers and storms to end your work week.
Temperatures will soar to the lower 90s today, but will feel like the triple digits. We have a heat advisory in effect until 8:00 pm this evening. We could see heat index values anywhere from 103° to 108°. We are tracking a cold front that will arrive late tonight and move out by Saturday afternoon. A few showers possible this afternoon and then better chances as the front arrives. A chance for showers Saturday as the front exits. Not going to be a washout by any means.
High pressure will build in on Sunday and Monday. It will still be humid on Sunday, but not as humid as the past few days. It will become more humid as the week progresses.
Good news, it’s still looking dry for the eclipse on Monday! We should see clear to partly cloudy skies with highs in the upper 80s. Showers and storms return Wednesday as a cold front moves in.
Tropical Storm Harvey approaches the Windward Islands. Will not be a threat to the U.S. We continue to keep an eye on an area of low pressure that continues to show signs of organization east of the Leeward Islands. It has a 70 percent chance of cyclone formation within the next two days. This system could become tropical storm Irma.
Today: Partly cloudy. Scattered showers and storms possible (40%). Highs in the low 90s. Winds: S 5-15 mph.
Tonight: Showers and storms (40%). Lows in the mid and upper 70s. Winds: S 5-15 mph.
