Topic: February starts warm and foggy
Following the trend of previous months, February started very warm this week with temperatures ranging from 15 to 25 degrees F warmer than average. Some observers in western Minnesota reported new record highs for February 1st including: 50 F at Morris; 51 F at Benson; 52 F at Ortonville and St James; 55 F at Marshall; and 56 F at Minneota. On February 2nd afternoon temperatures again reached the 40s and 50s F in some places, as Rochester reported a new record high of 48 degrees F. It was the warmest first two days of February since 1931.
In addition, along river valleys and in eastern and northern sections of the state fog was dense and very persistent the first three days of the month. Almost continuous fog was reported from some southern counties, along with some freezing fog. In the north, fog, overcast, and occasional snow flurries prevailed over the first three days of the month.
Topic: High Dewpoints Too
With the warm temperatures, melting snow, and fog prevailing this week near record to record-setting dewpoint values were seen at a number of locations. Dewpoints ranged from 35-40 degrees F during the day, more typical of April and May. The condensation produced by high dewpoints made many surfaces wet and slippery, which combined with the fog contributed to hundreds of traffic accidents around the state.

Heavy snows with blizzard conditions were reported from parts of Colorado this week. The National Weather Service reported snowfall rates as much as 2 inches per hour. Portions of Interstates 70 and 25 were closed to traffic for a time, and a weather observer west of Denver (near Pinecliff) reported 18 inches of new snow by Friday morning.
Heavy rains continue to fall over southern Madagascar which has seen little relief in two weeks. Following heavy rain from Cyclone Funso last week, tropical thunderstorms have continued much of this week. The rains washed out river banks, flooding hundreds of homes and displacing over 1000 people. More on Cyclone Funso can be found at...
Last week NASA renamed one of its polar orbiting satellites in honor of the late Professor Verner E. Suomi of the University of Wisconsin. Born in Eveleth, MN in 1915, Dr. Suomi is called the "father of satellite meteorology" having developed many of the instruments and tools used today during his tenure on the faculty of the Space Science and Engineering Center at UW-Madison, especially in the 1960s and 1970s.
