Forecast: Hot And Potentially Stormy All Day

A slow-moving frontal system from the west is bringing showers and storms to parts of the area this morning.

Monday night was certainly a warm one, with most areas seeing temperatures hang in the 70s. This made it tough to sleep without air conditioning. Meanwhile, many of the storms that developed overnight fell apart as they moved eastward.

Showers and storms will continue threaten the area all today, as we have plenty of humidity and a frontal system is crossing the area. Humidity levels will remain high all day, but both the heat and the humidity will end Wednesday.

As the front pushes offshore later tonight, a better weather system will follow. I expect Wednesday to be a transitional day between the humidity out there now and really nice, dry weather expected Thursday.

On Monday I wrote about a chance for rain at the end of the week. My thinking then and still is that I am just not convinced of a significant rain event for Thursday night and Friday. When I use the word significant, I mean over half an inch of rain. That amount of rain would be quite beneficial to the rapidly drying landscape.

I want to get a look at one more day of models before starting to give you times for any rainfall and amounts during those days. I will say that Friday looks like the least favorable day of the week. I do expect an improving forecast this weekend provided the weather system moves through quickly on Friday.

We could reach 90 again today, and if we do it will be the 7th such day this summer, which is not very many days in the scheme of a summer. It also would not be considered part of a heat wave, either.

Today: Showers and storms a risk much of the day, but periods of sunshine as well. Some storms could contain torrential rain. Highs 84-90.

Wednesday: Partly sunny and less humid, with a high 80-84.

Thursday: Mostly sunny, with a high in the upper 70s to near 80.

Friday: Potential period of showers, with a high 75-80.

Saturday: Clearing. Highs in the 70s.
