A moist air mass across the region prompted a call for patchy dense fog through Monday evening as well as a dense fog advisory and a flood watch for one eastern Indiana county.

At 8:15 p.m., the National Weather Service in Wilmington issued the statement about the fog for Auglaize, Champaign, Clark, Darke, Greene, Logan, Mercer, Miami, Montgomery, Preble and Shelby counties. Visibility may drop below a quarter-mile at times tonight.

Those counties are under a dense fog advisory until 4 a.m.

The dense fog advisory for Randolph County, Ind., has also been extended until 4 a.m. and the flood watch for that county extends through Wednesday.

A breeze of 10 mph to 15 mph all night should prevent fog from becoming too dense in most of our area, Storm Center 7 Chief Meteorologist Jamie Simpson said. Along with that, spotty showers are expected to continue overnight but the area will be mostly dry through Tuesday.

Temperatures will not drop much overnight and will climb back into the low to mid 50s by sunrise.

“The breeze likely picks up a bit tomorrow and that will help us hit the low 60s with just a little sun from time to time,” Simpson said.

The record high for Jan. 29 is 66 degrees and the area may come to within a few degrees of that mark.

“(Tuesday) is the day to enjoy the rest of the week, because Wednesday is windy, wet, then cold and snowy,” Simpson said.

Steadier and perhaps at times heavy rain will visit the area Wednesday morning, possibly affecting the commute. A few rumbles of thunder are also possible. Winds may gust up to 30-40 mph Wednesday morning as well.

For Wednesday, a cold front will move through midday or so and drop temperatures drastically.

“We’ll have a morning commute in the 50s, and an evening commute in the 30s, but not drop below freezing until later in the evening,” Simpson said.

There will be a break from the rain sometime in the afternoon, but it will pick back up in sometime in the evening.

“So not only do we drop below freezing later Wednesday evening, but we’ll get some snow showers as well,” Simpson said. “Initially these will have a hard time making roads slick due to the warmth tomorrow and early Wednesday, but at some point towards midnight or overnight we may start to get some slick spots.”

Rain Tuesday and especially Wednesday could wash away most of the road salt, he said, “so crews will need to treat again.”

A few more snow showers are possible Thursday followed by a quiet weather pattern Friday with some sun.

“We’ll stay below freezing until sometime next week after we drop below 32 Wednesday night,” Simpson said.
