SEPTEMBER LEVELS

The high temperature Thursday reached our forecast 74 degrees just before 4 pm.  The amazing autumn continues to roll along as  temperatures reached the normal for September 25th.  This is the warmest since November opened and since the record tying high of 78° on the second of the month.

69 days have reached 60° or higher this fall, the most since 1971's (70 days).

Friday's high record has stood since 1940 and is in jeopardy.  Before showers arrive late afternoon we are forecast to reach the lower 70s.  The record of 73° was set in 1941 and 1930.  The normal high is 51° and we will once again be 20° above normal.

AUTUMN STORM

The long advertised storm is emerging from the Rockies late Thursday afternoon.  This is the storm we highlighted nearly 2 weeks ago that would bring a shake up to the pattern around the 19th and 20th of the month.  Tonight, we are on the warm side of the storm while blizzard warnings are in effect over the upper Midwest.  Up to a foot of snow could fall over western Minnesota by Friday afternoon.

As of November 17th less that 5% of the U.S. was snow covered, the least amount this late into a November in the 12 years.
