Winter storm update Sat night

March 2nd, 2014 at 6:15 pm by under Weather

We had some sleet and snow this morning as the first wave of this winter storm moved through the Miami Valley.  There was a bit of a lull but now more snow and possibly a little sleet is heading toward the Miami Valley.

We still have a Winter Storm Warning in effect until 7am Monday along and south of I-70.

Several of you had to scrap off a thin layer of ice on your windshield.  While others had snow covered roads this morning.

Areas north of Dayton picked up a bit more snowfall this morning with the first wave of energy.  Others around the Miami Valley picked up about an inch. Dayton Int’l Airport picked 2.1″ as of right now.  This puts us at 47.5″ for the season which keeps us in 4th place for the most snowfall in one season.  Here are other area snowfall totals form this morning.

Snowfall totals

One thing this storm system has brought with it has been sleet.  There is a shallow layer of cold air meaning the precipitation starts off as snow, melts as it moves through a warmer layer and then refreezes as it falls into a layer of colder air below freezing.  This is when we get these ice pellets.  More sleet means less snowfall.

The rain snow line has been right over the Dayton area all day long.  We still have a slight chance of seeing some sleet tonight with the latest snow batch moving in.  Again because the cold layer is so shallow Doppler radar may show blue (which would normally indicate snow) but may actually be sleet. The rain snow line will be around us early this evening then falling south later tonight.

Snow may be heavy at times through the next few hours.  It may also mix with sleet early this evening.  The accumulation snow will eventually come to an end around 2am with a few flurries still possible early Monday morning.  Roads may be a bit icy for the Monday morning commute.  Here’s our TOTAL snowfall forecast.  This includes what has already falling this morning.

SNOWFALL FORECAST ADI

After the snow stops falling it is going to get cold.  Temperatures will fall dramatically tonight.  Cold air from Canada heads southward right over the Miami Valley.
