The episode as NWS CAR wrote it up.
Drought conditions generally worsened across the region during June. Severe drought conditions developed late in the month across portions of central and southern Piscataquis county along with southern Penobscot county. June rainfall for Bangor was only 0.97 inches...the second driest June on record. This was also the 4th warmest June on record for Bangor. Yearly rainfall totals for Bangor at the end of June were around 4.50 inches below normal. Near normal ground moisture and river levels existed at the start of the growing season in early May. Due to the dry conditions...water levels on the Penobscot and Piscataquis Rivers and tributaries had fallen to well below normal levels by late June. Lakes and reservoirs were also running at below normal levels at months end. Still being early in the growing season...agricultural impacts had been limited up to this point. The dry conditions also contributed to a relatively higher than normal number of wildfires.
