Weather from NBC Storm Team 4 — Updated 6:14 a.m. Sept. 1, 2015.

Unfortunately, there’s only a slight chance of rain this week. A few disturbances will move through the region over the week. Friday night will have the best chance of rain.

Today will be hot and humid with some clouds and fog to start. Once the clouds and fog begin to clear, expect sunshine to break through during the mid-morning to midday, taking temperatures into the lower 90s. Today will mark the beginning of a heat wave as temperatures will top out in the lower 90s for at least the next three days. Expect clear skies overnight with some areas of fog as temperatures fall into the 70s.

Tomorrow starts off with a mix of sun and clouds as temperatures once again rise into the humid lower 90s. A piece of energy will move out of the Ohio Valley tomorrow during peak heating hours, bringing a chance of some showers and thunderstorms to the region. By Thursday, the region will see partly cloudy skies with just a chance of a stray shower or storm here or there in the afternoon.

A backdoor cold front will begin to slide through the region on Friday night. Until then, increasing clouds on Friday will be the norm with temperatures topping out around 90 degrees. Showers and thunderstorms will accompany the frontal passage. A few showers or storms may linger into early Saturday. Saturday will feature gradual clearing with temperatures in the mid 80s. Saturday and Sunday will see more comfortable air after the front.
