The first 10 days of June were the warmest of any like period in the Fargo-Moorhead weather record dating back to 1881. The daily mean temperature over those 10 days averaged a bit over 10 degrees warmer than average per day. Eight of those 10 days were warmer than 90 degrees Fahrenheit and two were in the 100s. For Grand Forks, the same period was the third-warmest on record, also with two days of at least 100 degrees.
Scattered storms on the night of June 7-8 and again overnight into the early morning of the 11th brought welcome rain and helped to initiate a cooler weather pattern. It is very unlikely that either location will break the record for the warmest full month of June due to cooler weather building in today which is expected to last most of the rest of June. The warmest June month on record, based on the average daily mean temperature, for both Fargo and Grand Forks, is 1988.
