Radar early this morning detects some showers and thunderstorms in Western Pennsylvania that are moving east. That rainfall will move into the stable marine air over our region and likely weaken into showers and drizzle later on this morning. However, a round of showers or drizzle between 9 AM and 1 PM is not out of the question for many of us.
Today is shaping up as another cooler day east of the city than west but the temperature gradient will not be as extreme as yesterday when it was 56 in Philadelphia, 82 in Washington. We should see less of a sharp gradient today -- generally in the 50's east of the city, lower and middle 60's for most everyone around Philadelphia and the suburbs, and 65-70 in Central/Southern Delaware and Central Pennsylvania. These highs are assuming we get at least *some* sunshine in the mid and late afternoon...if we stay cloudy all day, Philly may not break 60 for a high. The unfortunate reality is that some low clouds may hang around into Saturday as well...it's not going to result in an "awful" St. Patrick's Day but it may be another tricky temperature day in the offing. Such is life near the Atlantic in early Spring when the ocean is still cool.
