Overnight: Showers are expected to move through tonight and the rain will continue to get heavier as we head towards daybreak Tuesday. While the severe threat tonight is not all that high, lightning and thunder as well as gusty winds will be possible. The biggest concern will be flooding. The ground is saturated, so any rain that falls, especially if it's heavy, will lead to a flash flooding concern.

Tuesday: Heavy rain is expected to start the day and could lead to ponding on the roads during the morning commute. A Flash Flood Watch is in effect until noon. A few more showers and possibly a thunderstorm will be possible towards midday, then there should be a break in the rain through most of the afternoon with highs reaching the upper 60s. More showers and storms are likely in the evening, arriving around sunset from the west.

"A cold front will produce these showers and storms, some of which could be strong to severe," Collar said. 

The biggest threats will be damaging winds and heavy rain that could lead to some flooding. Hail also is possible, and while the tornado threat is not high, it can’t be ruled out, Collar said.
