Dangerous heat and humidity blanket the region once again today with near record high temperatures.

Thursday: HOT & Humid; Near Record Highs; Few PM T-Showers

Highs: Near 100 | Feels Like: 105°+

Overnight: Early T-Storm; Then Partly Cloudy & Muggy, Patchy Fog

Lows: 74-80 | Wind: W 5-10

Friday: Partly Cloudy; Chance PM Showers/Storms

Highs: Mid 90s | Wind: Variable 5

High pressure will continue to act as a heat pump pushing daytime highs to around 100 degrees this afternoon and when combined with high dew points it will feel like 100-105. A few showers or storms may try to develop this afternoon over the mountains and then drift slowly east in the prevailing wind.

A shower or storm may linger into the overnight before diminishing leaving partly cloudy skies and muggy conditions in their wake.

A weak frontal boundary will drop into the region later in the day Friday and may act to support a few more scattered showers and storms in daytime heat that will reach the low 90s.

The weekend will be slightly cooling featuring daytime highs in the upper 80s with a daily chance of afternoon/evening showers and storms. Even cooler air will move back into place early next week.
