Preliminary climate summary for January 2012

Preliminary climate summary for January 2012 A very warm January prevailed across Minnesota. Many observers report mean monthly temperatures that are 7 to 9 degrees F warmer than average. Both Fargo-Moorhead and International Falls report their 5th warmest January in history, while on a statewide basis January 2012 appears to rank as the 7th warmest historically. Three new state record high temperatures were set for the month (on the 4th, 54 F at Marshall; on the 5th, 63 F at Marshall and Canby; and on the 10th, 59 F at Marshall). MSP International Airport reported only three mornings with below zero F temperatures, well below the average of eleven. The monthly temperature extremes were 63 degrees F at Marshall and Canby on the 5th, and -30 degrees F at Brimson (St Louis County) on the 20th.

Coldest readings of the winter so far

Coldest readings of the winter so far Some of the National Weather Service Offices issued Extreme Cold Warnings for parts of Minnesota this past Wednesday and Thursday (Jan 18-19) as a result of an arctic air mass advancing across the state and associated strong winds that produced wind chill values from -35 to -40 F. In fact overnight near Grand Marais a katabatic wind (drainage wind from higher elevation) peaked at 59 mph. These high winds made for some extreme overnight and early morning wind chill (WC) values along the north shore of Lake Superior with WC of -50 degrees F at Isabella, -51 degrees F near Grand Portage, and -53 degrees F near Grand Marais. On Thursday morning Minnesota reported the coldest temperature in the 48 contiguous states for the 3rd time this month with a low of -26 degrees F at Hallock, Park Rapids, Fosston, Babbitt, Orr, and Crane Lake. And again on Friday morning, Cook reported -27 degrees F (same as Churchill, Manitoba along the shores of…

More temperature records, then snow

More temperature records, then snow January 9-10 brought even more new high temperature records to the state and the region, adding to the previous weeks record-setting values. It was far and away the warmest first 10 days of January ever measured in Minnesota history, averaging over 20 degrees F above normal statewide (27.2 F versus a normal of 7.1 F). New temperature records were established for many Minnesota communities on January 3, 4, 5, 6, 8, 9, and 10, as a total of 163 new temperature records were reported, and 18 record temperatures were tied around the state. Three all-time state high temperature daily records were set.

On January 9th 37 communities reported new record high temperatures (values in the 40s and 50s F) topped by 57 degrees F at Milan and Redwood Falls, while on January 10th, new temperature records were set for 35 communities, including 59 degrees F at Marshall, which was a new statewide record high for the date In addition on January 10th aut…

Warm and record-setting start to January

Warm and record-setting start to January After starting New Years Day cold, icy, and snowy, the first week of January has brought temperatures that range from 8 to 12 degrees F warmer than normal on average, with all-time record-setting values on the 4th and 5th. For January 4th many western and southern communities reported new record high temperatures including: 47 F at Redwood Falls; 49 F at Browns Valley; 50 F at Luverne; 51 F at Pipestone and Montevideo; 52 F at Madison, Milan, and Canby; and 54 degrees F at Marshall and Minnesota (both in Lyon County). The last reading is a new all-time state record high for January 4th, breaking the old record of 50 F at Worthington in 1930.

Even more remarkable were the temperatures measured on Thursday, January 5th. It was clearly the warmest January 5th in state history as scores of observers reported new record high temperatures and the former state record high, 57 degrees F at Crookston in 1902, was shattered by a reading o…
