At least two storm systems will start out the month of March this year. The first one looks to bring a mixture of snow, freezing rain, and rain to the area on Sunday. The next will bring plenty of rain on Tuesday but may start off a little icy.
Winter Weather Advisory in effect until Sunday afternoon
A warm front moving north tonight will interact with a disturbance in the atmosphere to cause light snow to develop late this evening. Snow is expected to start after 9 p.m. north of Cincinnati and after 10 p.m. for the rest of the region. Watch for slick roads later tonight towards midnight if you have plans to be out. Temperatures will rise from the lower/middle 20s this evening to near 30 degrees by sunrise.
As some warm air aloft starts to move in thanks to that warm front, snow will mix with freezing rain especially south of Cincinnati overnight. This mixture zone will move north into the metro area by sunrise. A light glaze of ice will be possible on roads and elevated objects across much of the Tri-State except for far northern Butler/Warren/Clinton counties.
Temperatures will warm above freezing by 9-10 a.m. on Sunday morning. All precipitation will change to rain for most of the Tri-State by noon. Until then, roads may be very slick due to light snow and ice accumulation. Areas to the north (Brookeville, IN to Oxford, OH to Springboro for example) may remain mostly snow even though temperatures reach just above the freezing mark.
Accumulation: Snow totals will increase as you head north. With that in mind, 1-3” will fall across the heart of the area. 3-5” of snow may accumulate closer to I-70. South of the Ohio River, snow will mix with ice and rain faster leading to lower totals.
Showers will persist through the afternoon until a cold front moves through Sunday evening. With colder air filtering in, leftover showers may change to snow showers after dark. An additional light dusting to half inch of snow may occur as temperatures fall below freezing after 10 p.m.
Another big storm mid-week
Monday will bring a temporary lull between storm systems. As a stronger storm system develops on Tuesday, warm air will get pumped in from the south. Sub-freezing air near the surface may linger as rain overspreads the region Tuesday morning. This could lead to a brief period of sleet and freezing rain for the AM commute depending on the exact timing. This is an early heads up, so check back for updates as we get closer.
A significant rainfall (1-2”) may occur from the storm system on Tuesday into early Wednesday. With snow/ice on an already frozen ground, widespread flooding may become a concern. We will see temperatures spike into the 50s Tuesday evening and then tumble back down by Wednesday afternoon.
There is a small potential for another surge of moisture Wednesday evening with may produce some light snow. This will continue to be monitored. Hang in there because it is going to be a wild weather week!
