While we don't expect major severe impacts, we have issued a low-end NEXT Weather Alert for the Wednesday morning drive as heavy rain could lead to slow, possibly slick conditions.
At this time, total rainfall may end up in the 1-3 inches range by Friday, and since it will spread out over a few days, widespread flooding isn't a huge concern, though localized flooding is possible in the heaviest bands.

Memorial Day itself looks to stay mainly dry with some sunshine, but clouds may increase ahead of a disturbance that could bring showers Monday night.
Normal high temperatures for this time of year are in the mid-70s. Every day in the 7-day forecast is below normal for late May.
