Maryland to Pennsylvania Weather: 6/15/17

Today, I will linger in Ocean City, MD, for a bit before driving to Barclay, MD, and Millington, MD, and then across to Pittsburgh, PA.

This morning has been mild, foggy, and still.  I did go for a very pleasant 3-ish mile run this morning along the boardwalk in Ocean City.

National Weather Service (NWS) in Wakefield, VA, forecasts (for Ocean City, MD) a partly sunny day, with a high temperature of 73 F. The winds will be from the east at 11-13 mph.

The NWS in Philadelphia, PA, forecasts (for Elkton, MD) a mostly sunny day, with a high temperature of 81 F. The winds will be from the southeast at 7-13 mph.

The NWS in Pittsburgh, PA, forecasts (for Pittsburgh, PA) a mostly cloudy day, with a 60% chance of showers and thunderstorms, and a high temperature of 84 F. The winds will be from the south at 3-7 mph.  This evening will be mostly cloudy, with an 80% chance of showers and thunderstorms and a low temperature of 66 F. Winds will be from the south at 3-5 mph.

The visible satellite imagery shows clouds all over my travel route today.

The infrared satellite imagery shows that a few of these clouds are thick, and are likely precipitating.

The water vapor imagery shows plenty of deep, uniform moisture along my travel route today.

The 12Z soundings are unavailable at this time.

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

The surface pressure chart shows no strong pressure systems or gradients along my travel route this morning.  The RAP shows that none are expected to develop over at least the next six hours.

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 will be the word of the day.  I will travel through it off and on all day today.

It is going to be a cloudy, rainy, foggy, but potentially stormy day for me today.  I don’t expect severe weather, but a few storms here and there will be likely.

Thank you for reading my forecast.
