The low temperature at BWI this morning was 36 degrees, just 3 degrees shy of the record low of 33, reached most recently on this date in 1983.
Today (Monday) looks like it could be the best day of the week, weatherwise, with clear, sunny skies and high temperatures still a bit cool - in the mid-60s - but pleasant, especially in the sunshine. The average high for May 10 in Baltimore is 72 degrees.
