There is Flood Watch for the entire area which will go into effect late Friday night and last until Sunday morning.
Temperatures are in the 40s and much of the snow has melted into water. The ground is still frozen in most areas so the water will sit on top says Storm Center 7 Chief Meteorologist Jamie Simpson. There is still some uncertainty to where the heaviest rain will hit and when. Our area should still get at least 2" to 3" with possibly 4" by the time it ends. The forecast for river levels are to all have some flooding, starting as early as Saturday night, and perhaps persisting into Tuesday.
Tonight, cloudy and a bit breezy at times with showers arriving around 3 to 4 a.m. Temperatures should hold in the 40s all night with most waking up to lower-40s.
Friday, cloudy and a bit breezy still with off and on rain through the day, none of it expected to be heavy. Temperatures will rise into the mid-50s with perhaps a few upper-50s far south and lower-50s north. More rain at times Friday night.
Saturday, rain will be steadier through the day with the heavier rain likely arriving late afternoon or evening. Some of the computer forecast models actually push the heavy rain west of us overnight then swing it back through Sunday morning Simpson said. However, other keep it right over us all night. We'll just have to see how it plays out, but that's your difference between 2"-3" total or 4"-5" total. Temps might become fluxuating Saturday with a weather front right over the area. Highs will hit the 50s, but could be in the upper-40s far northwest in the afternoon, and the far southeast may get into the 60s. Possible thunder Saturday night. Streams and creeks will start to come out of their banks Saturday night.
Sunday, likely more heavy rain in the morning with a start in the 50s. The high temperature will be early in the mid-50s then fall throughout the day to about 40 or upper-30s at sunset. Rain should taper off about noon Sunday, and the larger rivers, including the Great Miami will flood Sunday as there will be a bit of a lag effect due to the smaller rivers feeding into the larger ones. The Mad and Little Miami River may be flooding early on already. Possible strong winds Sunday after the cold front passes the middle part of the day. There could be some gusts over 40 mph, and with all the rain, anything stronger could pull some trees out of the ground. As temperatures drop,a few snow showers Sunday night with little if any accumulation anywhere is possible.
Monday, wake up to temperatures in the 20s, Simpson says the water still sitting around could start to freeze. There may be a few flurries across the northern portion of the area, but shouldn't add up to anything. Some sunshine Monday, but temperatures should hold in the 20s all day.
Christmas Eve Tuesday, sunny but chilly with the chance of lingering flooding. Lows in the teens and high in the upper-20s.
Christmas Day Wednesday, partly cloudy with afternoon temps into the mid-30s after a start near 20 degrees.
Thursday, probably some snow showers, maybe light accumulation.
