KEY MESSAGES

Updated at 150 PM EDT Mon Sep 14 2026

- Dry for most of the area through the week with above normal temperatures continuing.

DISCUSSION

Issued at 150 PM EDT Mon Sep 14 2026

Currently another warm day with highs expected to climb into the 80's and 90's for most people in the Valley. A very weak boundary is pushing thorugh the region, but that's more of a technical term as opposed to a change in weather. It will have little impact on our sensible weather, as warm temperatures will persist behind it for the next few days due to a large mid/upper ridge across the region.

Guidance has come in a couple of degrees lower on the dew points for the upcoming week. So at this time it looks like we'll remain just a few degrees below Heat Advisory criteria (105) for the week if the forecast verifies. But it for sure will be a very hot and muggy week with highs expected to be in the 90 and 80's every day and dew points right around the 70 degree mark. Very little chances of rain even with these warmer temperatures as the ridge remains overhead and squashes pretty much anything that looks to try and develop.

Longer range models are showing a possible breakdown of the ridge in the weekend or early next week as a couple of systems try and move through the United States fighting against the ridge.

AVIATION

(18Z TAFS) Issued at 150 PM EDT Mon Sep 14 2026

VFR conditions expected for the next 24 hours. Can't completely rule out a brief bout of fog at TRI, but conditions are less conducive than the previous couple of nights, so have left it out for now.
