Wet Day; Enhanced Flood Risk Tonight For Some…

The National Weather Service has expanded the Flash Flood Watch to encompass more of the viewing area.  This is in effect until 8p Tuesday.

4Tropical moisture will continue to stream into the state tonight into Tuesday.  In fact, most intense rains will likely set up tonight and may feature “banding” signatures that would train over the same areas.  Within these intense rain bands, prolific rainfall rates can be expected, enhancing the flash flood risk.  Latest short-term model data shows this threat, and would place a premium focus on areas generally west of US-31.  We’ll have to keep a close eye on things.

2Plenty of “juice” is available to tap into across western sections tonight.  Precipitable water values (PWATs) of 2″-2.5″ will be more than enough to fuel torrential rainfall.
