Phoenix weather: Sunny forecast
Updated yesterday at 6:11 PM
PHOENIX -- A slow drying and warming trend is the forecast for this week. We’ll also see a gradual warm-up with high temperatures making it back into the mid-90s by late week. Then some more cool air is forecast for next weekend and temperatures will be headed back into the low 80s.
After a busy evening yesterday with scattered showers and thunderstorms reaching into the lower deserts, conditions across the region have quieted down. Skies have cleared for the most part with a closed upper low currently centered over Northern Sonora, Mexico. That low is slowly moving eastward.
Low-level moisture remains fairly high after an uptick yesterday and will again allow for more chances of showers and thunderstorms this afternoon and tonight, though not in the Valley but further to the east than on Sunday. The upper low is forecast to be just to the southeast of Tucson by late today resulting in a less favorable atmospheric profile for thunderstorms across south-central Arizona.
With less instability this afternoon the storms will be more isolated in nature, less organized and produce less outflows. The strong outflows on Sunday is what allowed for storms to propagate westward into the lower deserts. A repeat of Sunday is not forecast.
Lingering moisture on Tuesday should still allow for a few isolated showers or thunderstorms across eastern Gila County, but the gradual drying will eventually take away any threat of afternoon convection by Thursday throughout all of Arizona.
