DETAILED FORECAST:

OVERNIGHT: News Center 7 Chief Meteorologist McCall Vrydaghs said storms, some severe, will move into the Miami Valley from the north and spread south after midnight. Large hail and damaging winds are the primary threat throughout the entire area, but will be a greater risk north of I-70. An isolated tornado or two is also possible. These storms are expected to end to the south and around 5 a.m.

Now is the time to prepare, Vrydaghs said. Move cars into the garage to keep them from hail damage. Turn on your weather radio and allow push notifications to the WHIO Weather app before heading to bed. These will send audible alerts if a watch or warning is issued.
