Key Messages
- An increasingly synoptic supported heavy rain set up continues to evolve today, just hours following this dissipation of last night`s heavy rain MCS.
- Heavy rains will again break out tonight, especially along and north of I-80 and near and south of Highway 20. This area is already saturated, and is broadly included in a Flood Watch until 7 AM Sunday.
- The Marginal risk for isolated severe storms was added back to the area by SPC, but this risk remains conditional and low in our area.
