Patchy frost occurred over portions of the area throughout these 3 mornings, which was not normal for August.  As patchy frost also occurred on June 23rd and 24th, the only summer month that didn't have frost was July.  The usual date for a first frost is not until mid to late September.  Daily, monthly, and seasonal temperature records were all set.  On August 19th, the coldest morning temperatures were 34 degrees (11S Roseau) and 35 degrees (4S Humboldt and 7W Greenbush).  Record lows were set at Fargo (39) and at the Grand Forks airport (37).  On August 20th, the coldest morning temperature was 29 degrees (Thorhult and 6SW Warren).  Karlstad 2SE dipped to 30 degrees.  Record lows were again set at Fargo (34) and the Grand Forks airport (32).  On August 21st, the coldest temperature was 30 degrees (Thorhult).  A record low was set at the Grand Forks airport (38).  The normal low at this time in August was around 55 degrees.  When the month of August ended, it was the coldest August on record for the Grand Forks airport, and the second coldest at Fargo.  For the summer season (June, July, and August), it was the coldest on record for the Grand Forks airport and the seventh coldest for Fargo.  Damage to crops was widespread and yet spotty.  Crops in lower lying areas were more susceptible to frost than those slightly higher.  Some crops, like soybeans, edible beans, and corn, were also more susceptible to frost than root crops such as sugarbeets and potatoes.  Some crop varieties were also more frost resistant than others.  The cool summer and prior frosts put many crops about 2 to 4 weeks behind schedule.  The majority of crops that needed warm nights to mature (such as corn or tomatoes) were not expected to make it.  Minnesota crop losses were estimated at $190 million, over 2.8 million acres in 27 counties (14% of the total crop acreage).  However, this estimate did not cover the rest of the cold growing season.  The tourism/resort industry also reported decreased summer revenue.  Garden and vegetable farmers were hit hard, with some vegetables not ripening.  Leaves on trees turned color early and started falling from trees.  The bee industry was also hurt by the cold.  Minnesota was the nation's fifth honey producer in 2003.  The cold weather meant fewer blossoms and less active bees.
