Instability created by highs near 80 and an upper-level area of low pressure spinning just to our south looks to have many of us dashing through a downpour or two into this evening. Because the storms are slow moving, localized flash flooding is possible so drive with caution. We continue with a chance of showers and storms tomorrow, before we transition into a hot holiday weekend with temperatures making a run to near 90 or higher.

Through Tonight: Thundershowers are likely to be scattered across the area into the mid-to-late evening. With an 80% chance, a lot of you get an opportunity to use the umbrella. Downpours could lead to localized flash flooding. Evening readings in the 70s end up in the mid-to-upper 60s by morning (or sooner where downpours occur).

Tomorrow (Thursday): Early breezes from the east could sock areas from the city eastward in with fog and delay warming. But breezes most likely shift to come from the south by midday, giving us partly sunny skies and pushing highs to the low-to-mid 80s. Humidity is still plentiful and the added warmth is likely to set off more afternoon/evening thundershowers, though coverage should be more limited than today.
