Yes, Virginia (and DC and Maryland, too), there was a sunrise this morning, but a pesky overcast kept temperatures suppressed until sunshine began to break out this afternoon. At Dulles, the temperature jumped from 66° to 71° to 75° from 1pm to 3pm. Humidity at the surface is also much more noticeable today, with dewpoints as much as 20° higher than yesterday.Precipitation on radar at mid afternoon was mainly confined to a narrow band from southeast of Harrisburg across the head of the Chesapeake Bay to offshore of Ocean City. By late afternoon, there was a very small, but intense, cell in the vicinity of Williamsburg. All 3 major local airports reported merely a trace of rainfall, continuing the dry trend of this spring which has been broken only with a small excess of April showers.
As Josh explained earlier, what might have been a simple story of warmth building eastward from the center of the country into the Mid Atlantic area will be complicated by an upper-level low-pressure trough moving eastward just to the north of us.

Tonight and Tomorrow
There is still a slight chance of a shower somewhere in the region through this evening. Otherwise, conditions will be dry and mild, but with increasing humidity and lows only down to the mid 60s. Tomorrow will be more summer-like with a mixture of sun and clouds and a 60% chance of showers or thunderstorms by evening; highs should be in the low 80s.For the all-important holiday weekend forecast, scroll down to Josh's post below.
Tropical Topics
The official start of hurricane season is now a week away, and the National Center for Atmospheric Research (NCAR) has published a backgrounder page on their web site with lots of information on tropical cyclones. There are many links to further information for all levels of interest, from education for kids to the latest research results.
