Random pattern of thunderstorms prevails this month

Random pattern of thunderstorms prevails this month Much of the state has been missed by significant rainfalls this month, leading to more Minnesota counties placed in drought status by the U.S. Drought Monitor. Portions of Rock and Nobles, as well as Clay, Norman, Polk, Mahnomen, Pennington, Red Lake, Marshall, and Beltrami Counties were place in the "severe drought" category this week. Much of the rest of northwestern and southwestern Minnesota remains in moderate drought. Elsewhere portions of southern Wisconsin, southern Illinois, Indiana and northern Missouri were placed in the "extreme drought" category.

Despite this, some areas have seen significant, even record-setting amounts of rainfall. On Friday, July 13th International Falls received a record 2.68 inches while Spring Grove received a record 2.95 inches. On July 18th (Wednesday this week) Bethel, Isanti, and Rice received over 2 inches of rainfall, while Milaca reported 1.35 inches and…

Warmest first 10 days of July

Warmest first 10 days of July For the Twin Cities, and perhaps a few other climate stations, the first ten days of July 2012 have been the warmest in history based on mean temperature values. Seven of the first ten days brought daytime temperatures of 90 F or greater (two days were over 100 F), and on five nights the temperature remained above the 70 degrees F mark. These values produced a mean temperature of 82.7 degrees F, or 9 degrees F warmer than normal. The following is a list of the top ten warmest first ten days of July in the Twin Cities area going back to 1871:

1. 82.7 F in 2012
2. 82.4 F in 1948
3. 82.2 F in 1936
4. 81.2 F in 1989
5. 81.2 F in 1949
6. 80.8 F in 1937
7. 80.0 F in 1974
8. 79.2 F in 2002
9. 79.1 F in 2011
10. 79.0 F in 1988
