Wednesday: Mostly sunny with highs in the upper 50s to low 60s.

Thursday: Mostly sunny and delightfully warm with highs near 70.
An upper level trough was located over the northern and central Appalachians early Wednesday morning, but the presence of colder air aloft will have only a modest impact on the temperatures. The wind flow will still be out of the northwest with sustained winds averaging 10-15 mph Wednesday afternoon and most places topping out in the low 60s. High pressure will shift off the coast Thursday allowing a delightful southwest wind to kick-in. This will bring the upside potential for places like Baltimore and D.C. to hit 70 for the first time in 2014! In the event that we don’t quite make it to 70, high temperatures Thursday will be no lower than the mid to upper 60s region-wide.
Our next chance of rain comes to us Friday night as a cold front approaches from the Great Lakes region. An area of low pressure will develop along it and latest guidance suggests that we could see anywhere from 0.25-0.5″ of rainfall.
