Christmas Road Trip 2017: Day 15

Today is the fifteen day of our annual Christmas Road Trip.  We drove to Cleveland yesterday to visit some family and to attend the Trans-Siberian Orchestra concert, as is our tradition.  The ride home was treacherous, creeping along at 20-40 mph in the falling snow.  While it was only a half an inch deep or so on the roadway, it was that critical half an inch that was slippery.

Today, we took it easy.  I slept in until late, then woke up and shoveled the walk and brushed snow off the car.  I am off to a late start with today’s forecast.  We decided to stay put for another day in Medina before heading west.

The NWS in Cleveland, OH, forecasts (for Medina, OH) a mostly cloudy day, with a 70% chance of snow, and a high temperature of 17 F.  Winds will be 17 mph from the northwest, and will produce wind chill values of -4 F.  This evening will be cloudy, with a 60% chance of snow, tapering off to a 30% chance of snow by the morning hours.  The low temperature will be 3 F.  Winds will be from the northwest at 7-14 mph, producing wind chill values of -8 F.

The surface observations (from the SPC Mesoscale Analysis Map) show extremely cold temperatures and moderate humidity (based on the surface dewpoint depressions). The skies are cloudy and the winds are light and from the northwest.

There is still a dome of high pressure across the northern plains, and that high pressure is extending south and east.  This high pressure is our continental polar (cP) air mass that is causing such cold misery almost everywhere in the United States.

The HRRR simulated reflectivity shows snow tapering off this evening.  I didn’t include this image today.

The critical thickness are much farther south, so it is no surprise that any falling precipitation in Ohio will be snow.

The temperature will be cold again tonight.  We won’t escape the cold for several days yet to come.

Today and tonight will be cold and breezy.  Perhaps the snow will start to taper off in the early morning hours.  We will probably leave for…west…and perhaps south…tomorrow.

Thank you for reading my post.
