Some record-setting rains this week

Some record-setting rains this week Widespread rainfall was reported around the state this week, adding to an already wet month. Warm, moist air (dewpoints from 66 F to 70 F) produced strong thunderstorms which brought heavy rainfall to parts of northwestern and southeastern Minnesota overnight from May 29-30. In some cases new daily record amounts were set, including: 2.22 inches at Hokah, 2.59 inches at La Crescent, 2.32 inches at Spring Grove, 2.85 inches at Moorhead, 3.00 inches at Browns Valley, and 3.77 inches at Fargo, ND. As a result of these heavy rains the National Weather Service issued flash flood watches for some areas.

Preliminary climate summary for May 2013 For the 4th consecutive month Minnesota observers reported monthly mean temperatures that were cooler than normal. Most reports ranged from 1 to 3 degrees F cooler than normal for May. Combined with the temperature data for March and April, the overall spring temperatures (March-May) were the third…

Wet week

Wet week Many Minnesota observers, especially those in southern counties, have reported 6 to 7 consecutive days with rain over the past week. Over the period from May 17 to May 21 a number of observers reported new daily record rainfall amounts. Dozens of daily records were set, too many to list here. But some examples are:
May 17: 1.51" at Sherburn
May 18: 1.87" at Dodge Center, 1.78" at Spring Valley, 1.51" at Long Prairie, and 1.43" at Milaca
May 19: 1.46" at Jordan, 2.07" at Rochester, and 1.31" at Rothsay
May 20: 4.47" at Spring Valley, 4.01" at Thief River Falls, 2.75" at Grand Meadow, 2.21" at Grand Portage, and 2.01" at Roseau
May 21: 1.40" at Wadena and 1.15" at Walker

The wet week was dominated by high dewpoints. Just before 5:00 pm on Sunday, May 19th, the Twin Cities (MSP Airport) reported a dewpoint of 66 degrees F, tying the all-time highest value for the date set in 2004. Other obser…

Cold Mother's Day for some

Cold Mother's Day for some A strong low pressure system and associated cold front brought high winds for the Fishing Opener (Saturday, May 11), then some record low temperature readings for Mother's Day (Sunday, May 12th). Among those setting record low temperature readings on May 12th were International Falls (22 degrees F tied record low), Lake Kabetogama (23 degrees F), Orr (21 degrees F), Agassiz Refuge (20 degrees F), New York Mills (22 degrees F), and Wells (28 degrees F). Afternoon high temperatures remained cold as well at some northeastern locations including Babbitt (38 F) and Tower (38 F), while elsewhere they reached the more comfortable 50s F. Crane Lake set a new low temperature record on Monday (May 13) with a reading of just 19 degrees F, and Hibbing tied their low temperature record for the date with 21 degrees F. Then, with southeast winds and bright sunshine temperatures warmed into the 50s and 60s F by 6:30 pm that day.

More May Records

More May Records In addition to those recent early May climate records reported in Minnesota WeatherTalk Newsletter last week, some additional climate records were set during the start of May which I overlooked. May 3rd brought additional daily record snowfalls to Zumbro Falls (3.6"), Wabasha (3.9"), Minnesota City (4.0"), Winona Dam (5.0"), Theilman (5.3"), Lanesboro (6.4"), and Grand Meadow (9.0"). The storm total over May 2-3, 2013 of 17.2" at Dodge Center may have been a state record snowfall amount for a two-day may snow storm. The Minnesota State Climatology Office reports only one higher total May snowfall, that of 17.8 inches at Virginia (St Louis County) over the first 8 days of the month in 1954. Besides the snowfall records some new daily precipitation records were set as well, including 1.02" at Spring Valley on the 1st. On May 2nd even more daily precipitation records were set, including 2.12" at Red Win…

April climate summary, many records broken

April climate summary, many records broken April 2013 was arguably the most anomalous month since March of 2012 when nearly 800 daily climate records were set (mostly for warmth). It was the third consecutive month that delivered colder than normal temperatures to the state. Mean monthly temperatures for April ranged from 6 to 12 degrees F colder than normal. Extremes for the month ranged from -14 degrees F at Embarrass on the 20th and 21st to 85 degrees F at St James on the 29th. On a statewide basis it was the 5th coldest April in state history. Many locations reported record-setting cold maximum temperatures or cold minimum temperatures over the 10th through the 14th and again over the 19th through the 24th. In total, over 240 new daily cold temperature records were set including a -11 degrees F reading at Babbitt and Tower, and -13 degrees F at Brimson on the 20th. The reading at Embarrass (-14 F) on the 21st was not only a new statewide record low for the dat…
