Strong winds over the past week

Strong winds over the past week:
Since last Friday, October 20th we have seen more days with strong winds than any other period this year. These winds have been associated with a series of strong low pressure systems passing across the region. There have been frequent days with wind gusts well over 30 mph, and some days with gusts over 40 mph. In fact October 24th was a very unusual day in Rochester because the average wind speed for the entire day was over 20 mph, something that happens only about 2 percent of all days. Also on October 24th winds over 60 mph generated wave heights on Lake Superior that exceeded 20 feet on the eastern half of the lake.

The maximum winds over the past week here in Minnesota frequently gusted to over 40 mph. Those locations measuring such winds included;

MSP Airport, Moorhead, Morris, Crookston, and Marshall all reported winds to 41 mph.
Redwood Falls and Pipestone reported winds to 43 mph.
Benson reported winds to 44 mph.
Rochester reported winds …

Weather Pattern Reversal in October

Weather Pattern Reversal in October:
After a very wet first half of October, it appears that the 2nd half will be quite dry. During the first two weeks of the month 62 daily rainfall records were set or tied within the Minnesota state climate network, and over three dozen communities reported rainfall totals ranging from 5 to 8 inches, with nearly half the days of the month bringing rain. That pattern has completely reversed itself for the second half of the month, with little precipitation in the forecast out to Halloween. Though dry, the month will continue to be warmer than normal as it was this week.

A Dry Week Helps Farmers:
After a very wet first half of October, this week's sunny, warm, and dry weather has been very helpful for farmers who have resumed harvesting corn and soybean fields. Daily temperatures have been averaging 8-12 degrees F above normal this week. Over 90 climate stations have reported daytime high temperatures in the 70s F this week. The high tempe…

Very Wet October So Far

Very Wet October So Far:
Harvesting of corn and soybeans has been slowed or delayed due to wet weather this month. So far at least 55 climate stations have reported new daily record amounts of rainfall, mostly during the first three days of the month, and over the the sixth through the 9th. In addition many places have reported consistent rain, about every two days or so. As a result a number of climate stations, especially in southern counties have reported a total of 4 to 7 inches of rainfall and we have not reached the mid-point of October yet. Across Minnesota normal October monthly rainfall ranges from two to three inches, so many locations have already received twice the average amount.

This October rainfall pattern follows the recent trend towards wetter than normal. Sixteen of the past twenty-two Octobers in Minnesota have been wetter than normal on a statewide basis, with three among the top five wettest historically. The silver lining in all this is that for most place…
