Pennsylvania to Virginia Weather: 6/11/17

Yesterday, I spent the day driving around western PA, northern WV and a tiny bit into eastern OH.  Today, I will drive from Pittsburgh, PA, to Jersey, VA.

This morning has been mild, sunny, and still.

National Weather Service (NWS) in Pittsburgh, PA, forecasts (for Pittsburgh, PA) a sunny day, with a high temperature of 88 F. The winds will be from the southwest at 7-11 mph.

The NWS in Sterling, VA, forecasts (for Arlington, VA) a sunny day, with a high temperature of 94 F. The winds will be from the southwest at 5-8 mph.

The NWS in Sterling, VA, forecasts (for Jersey, VA) a sunny day, with a high temperature of 93 F. The winds will be from the southwest at 6 mph.  This evening will be mostly clear, with a low temperature of 70 F. Winds will be from the south at 7 mph.

The visible satellite imagery shows no clouds over my travel route this morning.  This image has been excluded from today’s post.

The infrared satellite imagery shows no thick clouds this morning, either.  This image has been excluded from today’s post.

The water vapor imagery shows that I will be traveling under a dry air mass today.

The 12Z soundings are unavailable at this time.

The surface observations (from the SPC Mesoscale Analysis Map) show mild temperatures, and moderately high humidity (based on the surface dewpoint depressions).  The skies are clear, with a light, southwesterly breeze.  There are no major frontal boundaries along our travel route this morning.

The surface pressure chart shows that I will be driving through high pressure all day today.  The RAP shows that no strong pressure gradients are expected to develop over the next six hours, though the high pressure system will remain.

Synoptically speaking, the 300 mb NAM chart (from Unisys) shows that the region is under light, zonal flow this afternoon.

The 500 mb NAM chart shows that there is no strong vorticity advection over the state today.  This chart has been excluded from today’s post.

The 700 mb NAM chart shows no major pockets of rapidly-rising air along our route today.  This chart has been excluded from today’s post.

The 850 mb NAM chart shows no strong thermal advection over the state today.  This image has been excluded from today’s post.

The Precipitation chart shows that rain is unlikely along my travels.  This chart has been excluded from today’s post.

It is going to be a hot, potentially humid, still day today.  Drink plenty of water!
