PM Update: A couple strong storms possible through this evening
Storms are likely to be widely scattered but may produce damaging winds, hail and perhaps an isolated tornado.
While we don’t have a widespread risk for thunderstorms late this afternoon and evening, of the few that may develop we could see a couple thunderstorms with damaging winds, large hail and possibly a tornado. Confidence is a bit low, but still worth flagging. Sunday may also bring a late day chance of storms, but a more limited risk of severe weather.
Through tonight: We have about a 2 (slight) out of 5 chance that any storms developing through this evening turn severe. While we aren’t confident that numerous storms develop, the few that may pop have an elevated chance of packing a punch, including some downpours, lightning and the outside chance of damaging winds and hail. Otherwise, skies will remain mostly cloudy and soupy, with low temperatures dipping only into the upper 60s to low 70s.
Tomorrow (Sunday): Showers and storms remain in the forecast, particularly during the afternoon hours. So far, chances for strong to severe storms remains low. Skies will again have periodic clouds but it will be a bit brighter than Saturday, with partly sunny conditions.
High temperatures will be near 90 to low 90s, but will feel more like mid-90s thanks to steamy conditions as dew points hover around the 70-degree mark. Southwesterly winds around 10 mph could gust near 25 mph a couple times.
