Weather update: Relief to the heat in sight?

Posted: Updated:

Oppressive, broiling, hot, muggy...those are all words to describe the weather we've seen this week. I think we have at least 2 more days of high temperatures at or above 100, then we will get some relief. It will still be hot, it will still be humid, but it will, at least, be a few degrees cooler.


Let's talk about tonight. We had a low of 79 last night. I think most areas will be hard to drop below 80 tonight, especially in urban areas. Heat indices will most certainly stay well into the 80s overnight.

For Thursday and Friday, more blazing sunshine. Highs will range 100-104 both days. Heat index values around 115 during the middle afternoon hours. It may be around 120 in the Delta.

Despite the very hot and moist atmosphere, we're still having a hard time getting isolated afternoon storms to pop. The large area of high pressure (the heat dome) is just about over us and that tends to squash any storms from forming. I won't rule out a very isolated storm on Thursday, but chances are well below 20% and I'm leaving rain chances out of the official forecast.

By Friday, the large high pressure will begin to shift west a little. We'll still be hot, but there is a little better chance for a few storms in the eastern half of the state.

Over the weekend, the high will continue to shift west. This will help us to have a better coverage of storms and clouds, and as a result, high temperatures will be a little cooler. A few areas may be around 100 on Saturday, but by Sunday, highs will generally be in the middle to upper 90s.

Daily afternoon storm chances will continue through at least the middle of next week.

Switching gears to the tropics, Emily continues to churn just south of the Dominican Republic this evening. The system will turn to the northwest by Thursday morning and move across Haiti and eastern Cuba. The official forecast from the National Hurricane Center keeps the center of Emily away from the southeast coast of the United States, but there may be some big waves and rip currents along the coastal areas. Emily will not have an impact on our weather.
