First Alert: None (Isolated severe thunderstorm risk through Monday evening)
Aware: Unsettled weather pattern continues through midweek
Some sunshine is starting to emerge from behind the clouds, and we could still see a few thunderstorms develop through mid-evening with continuing showers until around midnight.
After that, patchy fog will develop, and we'll do it all again for yet a third straight day on Monday. A few showers will start to pop up around noon tomorrow with the chance for isolated storms (some with severe potential) by late afternoon, though early evenings, depending on the heat of the day and whether sunshine can break through to fuel some instability.
Areas that see the most and longest duration of clearing will build up some potential energy that will support scattered to numerous thunderstorms on Monday that could have strong winds or even hail. The chances dwindle after sunset and disappear after 11 p.m.
Highs will be in the mid-70s. Tuesday will trend to be an overcast day with scattered to numerous rain showers as the upper level low and its saturated column of air move overhead.
Some lingering rain showers are expected Wednesday morning before this system finally starts to exit to the northeast.
Thursday and Friday look dry for now, but models disagree on whether another similar cutoff low pattern will move into our area again by next weekend. Stay tuned!
