Latest on Flood Watch and severe storm potential

Updated:
INDIANAPOLIS -

The latest wave of rain and thunder continues to impact southern Indiana, with heavy rain potential from Seymour to Bedford the next few hours.  It appears another complex of rain and thunder will emerge from the west by daybreak, setting the stage for a soggy start Thursday morning.  Heavy downpours may add time to your commute Thursday morning.

This wave should depart by midday and lingering cloud cover may prohibit afternoon storm development tomorrow.

But we're still eyeing late Thursday night into the predawn hours of Friday for severe storm potential.  Damaging wind appears to be the main threat as a line of storms crosses the state, but embedded spin-ups along the line cannot be dismissed either.  The entire state is under a Slight Risk of severe storms during that time and Watch Boxes may be needed.

Subject to change, but cellular type storms should congeal into a linear feature Thursday evening… and become our primary source for severe weather mainly between 12am-7am Friday.  At this time there is a medium threat for damaging wind gusts (>=58mph) and a low-end threat for tornadoes.  But overnight linear structures being fed by a modest low-level wind field have produced tornadoes in Indiana before.  Regardless… I have a way to get watches and warnings, and have your weather radio turned on.

THREATLEVELS

Flooding is a big concern due to waves of heavy rain that may reach 4″+ in some locations within the next 48 hours.  Be cautious and don't drive over water-covered roads.

Expect a wet start Friday with early morning highs in the 60s, but temperatures tumble into the 40s Friday afternoon after the passage of a cold front.  We anticipate a dry weekend in the post-frontal air mass, with frosty mornings near 30 and pleasant highs in the 50s.  Have a great evening despite the rain.
