WeatherTalk: April 1 through May 15 is the wettest on record
This is almost triple the average for the period.
FARGO — April and the first 15 days in May was the wettest, by almost an inch, in 142 years of record keeping for Fargo Moorhead. For Grand Forks, it has been the wettest, by about a third of an inch, in the 130 years of the record.
Fargo precipitation since April 1 has been 7.88 inches and Grand Forks has received 8.91 inches. This is almost triple the average for this period and would be almost double the average for a month and a half in the middle of summer; our wettest season.
Had such an abundance of rainfall (and snow) occurred during March, when the winter snow pack was melting, the entire region likely would have had the worst flood on record. As it turned out, most of the winter snow melted and flowed downstream without all this water added to it. The driest April 1 through May 15 period on record was in 1980 when Fargo received only 0.06 inches of precipitation and Grand Forks only got a trace.
