Pennsylvania Weather:  6/10/17

Yesterday, we drove from Lodi, OH, to Cleveland, OH, to Pittsburgh, PA, mostly in light rain showers.

This morning has been mild, mostly cloudy, and still.  The clouds seem to be clearing out, however.

National Weather Service (NWS) in Pittsburgh, PA, forecasts (for Pittsburgh, PA) a mostly sunny day, with a high temperature of 84 F. The winds will be from the southwest at 8-10 mph.

The NWS in Cleveland, OH, forecasts (for Erie, PA) a mostly sunny day, with a high temperature of 77 F. The winds will be from the west at 11 mph.

The NWS in Pittsburgh, PA, forecasts (for Steubenville, OH) a mostly sunny day, with a high temperature of 82 F. The winds will be from the southwest at 8-10 mph.  This evening will be mostly clear, with a low temperature of 61 F. Winds will be from the southwest at 8-10 mph.

The visible satellite imagery shows a cluster of clouds over the eastern parts of Ohio, as well as the eastern half of Pennsylvania.

The infrared satellite imagery shows that these clouds are moderately thin, with warm, low tops.

The water vapor imagery shows nearly uniform moisture over the area I intend to explore 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 mostly clear, with a light, southwesterly breeze.  There are a few showers still in the area, but they will clear up this morning.  There are no major frontal boundaries along our travel route this morning.

The surface pressure chart shows that we are under no strong pressure systems or gradients, and the RAP shows that none are expected to develop in the next six hours.

Synoptically speaking, the 300 mb NAM chart (from Unisys) shows that we will remain in the western edge of a small trough again today.  This trough is broadening and attenuating.

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 possible in eastern Pennsylvania, but it is unlikely around Pittsburgh and western Pennsylvania, where I intend to explore today.

There may be one more shower this morning, but the skies will clear out by the late morning.  I will be driving around western PA and eastern OH playing on amateur radio, and I expect to see a sunny day today.  We may go to a Pittsburgh Pirates game later, and I expect no rain delays.

Thank you for reading my forecast.
