BWI rain tally for 2009 nears 50 inches
Paul M. Novak Jr., of Baltimore, sent me this beautiful photo he shot over the weekend. He said:
"I was in Ocean City this weekend and caught and unexpected shot of a rainbow over the Ocean. It was a very blustery day, and just a real brief shower had passed through the area. I looked out of the hotel and here is what I managed to capture !"
Also in my mail this morning was this sort-of-related note, from Kevin Manning:
"As we approach 50" of rain for the year, can you inform us on the historical records for yearly rainfall? We are nearly 10" above the long-term average, so far this year."
The precipitation total for the year at BWI-Marshall Airport has nearly topped 49 inches. The long-term average for the airport for an entire year is 41.94 inches. So, after a bit more than 11 months, we are already nearly 7 inches above the yearly average. With just average precipitation in December we should have a 10-inch surplus for the year.
(Year-to-date for Seattle, Wash.: 35.69 inches. That city's reputation for rain is misunderstood. While they have many gray, damp days, the accumulations are generally small, summers are dry, and annual totals are modest.)
But remember that as wet as it's been in Baltimore since April, we began the year very dry, and ended March in drought. So, we are still a long way from record territory, and we'll need a deluge in December just to break into the top five wettest years on record (since 1871) for Baltimore:
2003: 62.66 inches
1889: 62.35 inches
1979: 58.98 inches
1996: 58.31 inches
1952: 56.57 inches
