Frosty tonight as temperatures fall behind a cold front



We are starting to dry out after a cold front brought one last downpour to the Miami Valley. Through the event, Bellefontaine picked up 2.14 inches of rain and Dayton recorded 1.27 inches of rain. We now have a surplus of 1.89 inches for the month of May. There is still a 1.54-inch deficit for the year in Dayton.

Behind this cold front we will continue to see wind gusts around 20-30 mph through about 10 p.m. After that the wind will begin to calm. The skies will begin to clear and temperatures will fall into the 30s.

A Frost Advisory is in place for all of the Miami Valley except Warren and Clinton County. Frost formation is likely and sensitive plants should be covered. There’s a low risk for frost Monday night and a higher risk again on Tuesday night as temperatures stay well below normal.

4:30 PM UPDATE: At Sidney, the Great Miami River is expected to crest at 10.3 feet on Monday. This is just barely above the flood stage at 10 feet. The river will approach the bank on the west side of Custenborder Field.

3 PM UPDATE: A band of heavy rainfall is moving east along a cold front mostly impacting the southern half of the Miami Valley. Wind may gusty around 40 mph as the cold front moves through. This will be our last surge of rain for the day.

10 AM UPDATE: Rain has started to move across the Miami Valley along with thunderstorms. The National Weather Service said rain will continue to spread into the early afternoon.

A tricky forecast this Mother’s Day. A warm front is trying to push northward and temperatures will depend on how far north the front pushes. Temperatures to the north of the front stay in the 40s and low 50s, while to the south of the front temperatures should rise into the low 60s. Heavy downpours are possible with one to two inches of rain possible. A few storms may develop with isolated severe storms.

TODAY: Showers likely, with isolated storms. Gusty winds, cool. High 60

TONIGHT: Showers end and chilly. Low 38

MONDAY: Partly sunny and cool. High 60

Dry weather for much of the week ahead. Temperatures stay below normal throughout the week.
