MONTHLY SUMMARY June ended up with near-normal temperatures, despite a near-record warm start. The temperature trend was unusual, in that the warmest temperatures occurred during the first 10 days, peaking at a warm 85 on the 9th. However, there were no days above 80 after the 13th, which is unusual for June. There was a cool stretch at mid-month, particularly on the 18th-19th when the mercury failed to climb out of the 50s. Temperatures returned to seasonal to slightly cooler than normal the remainder of the month. The coolness of the second half of the month virtually offset the warmth of the first half. There were 17 days with thunder during June, which is probably a record for any month. My previous record for LaVale was exactly 10 years ago in June 1998, the same month as the Frostburg Tornado. Not surprisingly, precipitation was above normal: although not excessively so, June was the third month in the first six with over 6 inches. There were some pretty good downpours, but no excessive amounts. There were also quite a few mere misses--had a few storms tracked a few miles north or south, we could have easily had 1 or 2 inches higher. Still, June will be remembered for its wetness and many days (20) with measurable precipitation, much like May which also had 20 days of measureable precipitation, and also the numerous thunderstorms.
