         January 2001 St. Cloud weather summary

        After an extremely cold December, the atmosphere continued to

defy prediction in Saint Cloud by producing an extremely warm January.

The average January 2001 temperature at the Saint Cloud Airport was

15.9 degrees, 7.8 degrees above normal. This mild January was actually

warmer than any January since 1990 and ranks in the warmest 15% (23rd place)

of the 121 Januaries on record. Yes, that means it was warmer last month than

during any January during our 3 consecutive warm winters. January 1998 was

the warmest January of our 3 mild winters with an average temperature of

only 15.5 degrees. There were almost as many days during January 2001 with

a high of at least freezing (10) as days with a low of zero or colder (12).

The warm days included a high of 42 on the 4th, which set a new daily

record by 4 degrees.

        The warm weather also was quite dry until the end of the month.

Only 5.4 inches of snow fell in Saint Cloud, about half of the normal

January snowfall. This total was the lowest January snowfall in Saint

Cloud since 1991. Still, we have already exceeded last year's seasonal

snowfall of 28 inches and are well on our way to an above normal

snowfall year.

        The dry pattern dominated most of the month as the

main storm track stayed across the southern US while a secondary jet

stream kept the arctic air trapped in extreme northeastern Canada. The

pattern did change at the end of the month, allowing a low pressure

system to tap Gulf moisture. While this storm of the 29th and 30th dropped

.52 inch of melted precipitation, only 2.8 inches of wet snow accumulated

in Saint Cloud since there was not enough cold air to keep the precipitation

as all snow. This is in marked contrast to the 18 inches of snow picked up in

Sioux Falls and the foot seen in some communities of west central and southwest

Minnesota. The .48 inches of melted precipitation which was measured on the

30th did set a daily record for precipitation.

       It does appear that a more northerly flow is developing for early

February, so our mild weather will not continue.

       I don't know if this weather news is good, but some of the extremes

apparent in December have turned out not to be quite as extreme. The apparent

record low of -26 on Christmas Day turns out not to have been a record low.

Pete Boulay of the State Climatologists' Office has gone through the old

handwritten records recorded by the National Weather Service when they had

an office in Saint Cloud. He has identified 10 days with lows of -40 or colder

in the 1880's when observations were being taken near the site of the current

dam in Saint Cloud. The record low for Saint Cloud on December 25 was not -25

as previously thought, but -42 set in 1884. He has also been able to show that

the all-time Saint Cloud record low is not -43 recorded on January 9, 1977.

The temperature has dropped to -50 twice: on January 2, 1885 and January 21, 1888.

Still, the day holding Saint Cloud's record cold average temperature (and the last

day that the temperature hit -40 in Saint Cloud) was set within recent memory: on

February 2, 1996, the high was only -20 and the low was only -40. The -30 average

temperature for that day still stands as the coldest in Saint Cloud history. The

only air in the Northern Hemisphere which could threaten that record remains

safely locked in interior Siberia, which is bad news for them, but good news

for us.
