Weather for Wednesday, April 21, 2010

Gonna throw up the WV Imagery from WeatherTap, as this will have implications on the weather for tomorrow.

What are we looking at? Currently, there is a rather potent s/w treking through theTennessee Valley. The HPC surface analysis shows a 1016mb surface high off Hatteras, and a 1015mb surface high over Chicago with a surface cold front centered off the Northern G/L. A surface trough can be found along the spine of the Apps. What does this all mean?

Well first, the infrared satelite image shows high clouds streaming in from the southwest, now overtaking Eastern PA, NJ, LI, and into Eastern CT. Clouds will increase tomorrow as the front continues to near and the s/w translates eastward. There is a risk for some showers during the afternoon, but any lifting mechanism will be quite weak, even though there is some frontogenesis, and the showers will be scattered in nature. Some instability can be found in southern areas in southern NJ, southern PA for example. I can't rule out a few rumbles of thunder as well. Highest temperatures to the NE, lowerst temperatures to the SW. Temperatures in the 60's can be found for most areas tomorrow.
