Today's weather will have the greatest impact on the forecast, with widespread showers and thunderstorms expected from morning through the evening. Some of the rain will be heavy at times, and rainfall totals of 1 to 2 inches are likely, with locally higher amounts possible. That amount of rain could quickly lead to flooding in poor-drainage areas, on roadways and in other low-lying locations.

The unsettled weather continues into tonight as showers and thunderstorms remain likely. Additional heavy downpours are possible before the rain gradually begins to taper late tonight into early Tuesday. Flooding concerns may persist where the heaviest rain falls.

Tuesday won't be a washout, but clouds will linger with a few leftover showers, mainly during the morning and early afternoon. Sunshine returns Wednesday, bringing a stretch of warmer, quieter weather through Thursday before scattered afternoon thunderstorms make a comeback later in the week.

Today: Periods of heavy rain and thunderstorms with localized flooding possible. Highs in the lower to middle 70s.

Tuesday: Mostly cloudy with scattered showers, especially during the morning. A stray afternoon thunderstorm is possible before gradual improvement. Highs in the lower- to middle-70s.

Wednesday: Mostly sunny and pleasant. Highs around 80 to the lower-80s.

Thursday: Mostly sunny and warmer. Highs in the mid-80s.

Friday: Partly sunny with scattered afternoon and evening showers and thunderstorms possible. Highs in the upper-80s.

Saturday: Mostly sunny with scattered showers and thunderstorms possible. Highs in the mid- to upper-80s.

Sunday: Mostly sunny and warm. Highs in the mid-80s.
