Rainfall in the first two weeks of June was heaviest in Baltimore… (National Weather Service )
June 15, 2012|By Scott Dance
Thanks to the June 1 thunderstorms that spawned 12 tornadoes across the state, the monthly rainfall total is running ahead of normal halfway through the month. But another good dose of moisture is needed to keep it that way.
At BWI Marshall Airport, there has been 1.98 inches so far this month, 1.55 inches of it June 1. Other parts of the state have seen significantly more rainfall in June (more than 5 inches fell in parts of Baltimore and Harford counties so far this month, as you can see above), but the measurement at BWI is the tally of record.
In a normal June, 3.46 inches of rain falls on BWI. So for a rainfall tally equal to or greater than the historical average, another inch and a half is needed.
If June rainfall stays above normal, it would be the second time since September, when more than 13 inches of rain was a staggering 9 inches above normal. In December, 4.5 inches of rain fell, just more than an inch more than normal. Since then, a rainfall deficit of 6 inches has built up.
Still, drought conditions that had worsened earlier this year have subsided for most of the Baltimore area. The Eastern Shore remains abnormally dry or in moderate drought, according to the U.S. Drought Monitor.
With the spell of dry, pleasant weather we're expected to be in through the weekend, though, who really wants to think about rain?
