Christmas Road Trip 2018: Day 13

Today, we will travel from Jersey, VA, to Barclay, MD, to Breezewood, PA.

I’m not sure of our schedule, as we will bounce between all of these as soon as we get packed up and have dealt with a few things along the way.  We will take US-301 for most of the early part, and we have not picked out a route from Barclay to Breezewood.

This morning has been cold, clear and still.

The NWS in Sterling, VA, (for Jersey, VA), forecasts a partly sunny day with a high temperature of 49 F.  Winds will be calm, becoming southeast at 5-7 mph in the afternoon.

The NWS in Philadelphia, PA, (for Barclay, MD), forecasts a cloudy night with an 80% chance of showers, and a low temperature of 41 F.  Winds will be calm, becoming southeast at 8-14 mph.

The NWS in State College, PA, (for Breezewood, PA), forecasts a cloudy night, with a 100% chance of showers and a low temperature of 43 F.  Winds will be from south at 6-11 mph, gusting to 20 mph.

The visible satellite imagery shows very few clouds over our route this morning.  This chart has been excluded from today’s post.

The surface observations (from the SPC Mesoscale Analysis Map) show cold temperatures and high humidity (based on the surface dewpoint depressions). The skies are currently sunny (according to the sensors) over our route.  Winds are light and variable.

The surface pressure chart shows high pressure and no strong pressure gradients over the state today.  The RAP shows that this trend will continue for at least the next six hours.  As we approach Breezewood, the pressure gradient will increase.

The HRRR simulated reflectivity shows precipitation is possible this evening, and will definitely happen tomorrow.   Notice the long squall line that will pass through tomorrow.

We will see temperatures reach their high in the mid 40s F, around 21 Z along our travel route.

The skies will begin to cloud up this afternoon and remain cloudy this evening.

Today will be a sunny in the morning, but will cloud up and begin to rain before we’ve reached our destination.  Thankfully, it will only be rain, unlike many of our holiday road trips.
