Roller coaster temperatures July 18-21

Roller coaster temperatures July 18-21 Thursday, July 18th brought very warm temperatures, oppressive dewpoints and high Heat Index Values (ranging from 98 F to 107 F) across southern Minnesota counties. Record tying and record setting warm overnight low temperatures were also noted by some observers including MSP Airport with 80 degrees F (tied 2011), and Thielman, Melrose, and Isle with 73 degrees F (new record warm lows). If you want to read more about some of the history of warm nights in the Twin Cities when the temperature does not fall below 80 degrees F the Minnesota State Climatology Office has posted a narrative on their web site.

Just 3-days after July 18th, on Sunday (July 21st), a cool, dry Canadian air mass brought some near-record setting low temperatures to northern Minnesota observers, with many readings in the low to mid 40s F. International Falls tied a record low on Sunday with 41 degrees F (matching 1947), while Crane Lake reported a new record low…

Record Rainfall on July 13

Record Rainfall on July 13 For some Minnesota citizens the early morning hours (4 am to 8 am) on Saturday, July 13th were quite noisy, with thunder, high winds, and very heavy rainfall. The rainfall amounts ranged from 1 to 3 inches across many east-central counties, and were even higher in parts of Scott, Rice, Steele, and Waseca Counties. Some National Weather Service observers reported new daily record amounts for July 13th, including 3.80 inches at Wells, 3.02 inches at Chanhassen, 2.79 inches at MSP Airport, 2.75 inches at Rosemount, 2.44 inches at Brainerd, 2.30 inches at Faribault, 2.23 inches at Rockford, and 1.82 inches at Owatonna.

These rains caused the National Weather Service to issue a number of flood warnings for areas along the Vermillion, Straight, and Cannon Rivers, and flash flood warnings for many communities, including Wells, Faribault, Northfield, New Market, Dundas, and Shakopee.

First significant rain of the month

First significant rain of the month July 9th (Tuesday) brought thunderstorms to Minnesota and the first significant rainfall of the month for many. Several observers in northern, east-central, and southeastern Minnesota reported amounts ranging from 0.50 inches to over 1 inch. Some of the larger amounts included 1.11 inches at Hallock, 1.72 inches at Waskish, 1.25 inches at Montevideo, 1.07 inches at Gaylord, and 1.00 inches at Vesta. Yet more rainfall is expected over the weekend and into next week, coming at a key time for the state's rapidly growing corn and soybean crops, and newly seeded alfalfa fields.

Comparing the Twin Cities Heat Waves of 1936 and 1995 The two hottest July 12th dates in Minnesota state history occurred in 1936 and 1995. They were both associated with multi-day Heat Waves, but there was a distinctive difference in their character. In 1936, a serious drought had a grip on the state too, as the month of July brought only 0.11 inches of rain…

Best days of the summer this week

Best days of the summer this week Weatherwise, we are experiencing perhaps one of the best starts to July in recent years. Low temperatures have been in the 50s and 60s F with daytime highs in the upper 70s to low 80s F and plenty of sunshine. Little rainfall so far this month following a generally wet June and wet spring. Thankfully dewpoints have remained in the comfortable 50s F providing near perfect weather for outdoor activities. Even at Embarrass, MN overnight lows have not dropped below 41 degrees F, while daytime highs have risen to 82 degrees F.

The July 4th weekend will bring some warmer than normal temperatures that will linger through Monday. On July 4th MSP, Wheaton, Fergus Falls, Browns Valley, Montevideo, Milan, Wheaton, Moorhead, and Ortonville all reached 90 degrees F. This marked the 22nd time the Twin Cities has recorded at least 90 degrees F on Independence Day since 1871.
