Climate Impacts - June 2003

Monthly Summary

Ten states in the region were below normal in temperature for June which stretches the streak of cold months in the Northeast to nine in a row. Several months in this streak have not been significantly below normal, but just cool enough to keep the streak alive. June did not fall into that category. With a regional average of 63.8 degrees, this was the coldest June since 1992 in the Northeast. West Virginia, Pennsylvania and New Jersey all recorded a negative departure from normal of over 2 degrees. For West Virginia this was the tenth coldest June on record. The rest of the region was generally about 1 degree below their averages with the exception of the northern New England states which were very close to normal.

For the past three years June has been a wet month in the Northeast and June 2003 didn't disappoint. While not as abnormally wet across the region as May, several states received more than 6 inches of rain and New Jersey ended the month with a total of 8.61 inches. For New Jersey that total is more than twice the normal and makes this June the wettest on record in that state. This was also the third wettest June for Delaware and the fourth wettest on record for Maryland. These states, and also Connecticut and West Virginia, were all over 6 inches on the month. Further north was a different story as Vermont, Maine, and New Hampshire all fell short of their monthly normal rain total. New Hampshire was almost an inch below normal and despite the heavy rains over the Northeast the past couple months, this is the fourth month in a row that Maine has been on the dry side of it's average rainfall amount. Overall this June was the 11th wettest on record out of 109 years of climate data.
