Longest November Frozen Streak

22 Nov 2014 12:54 PM
Mild air has thankfully returned to much of the country allowing for temperatures to rise above freezing. This ends a remarkable period of November weather with consecutive days below freezing. The featured map displays an analysis of the HRRR weather model's initialization of 2 meter AGL temperature. This model is run every hour, so the map displays the maximum period of hourly analysis below freezing for each grid point in the model over the CONUS. The map nicely shows the extent of freezing weather into the southeastern US.

November Frozen Streaks

20 Nov 2014 05:42 AM
The streak of weather below freezing continues for Des Moines this morning. The current streak is now longer than any previously recorded in November as shown by the featured chart of November streaks greater than six days. A strong chinook event yesterday morning put some doubt into setting this record as the temperature reached 30 degrees with a 50 mile per hour gust in the early morning hours. Temperatures will be on the rise Friday evening and will be above freezing on Saturday, so we have two more days to go!

Week of Frozen Weather

19 Nov 2014 05:49 AM
Our current stretch of cold weather is remarkable for mid November. The featured chart looks at the current streak of sub freezing temperatures. This chart has changed significantly overnight as some chinook winds from the west have raised temperatures above freezing for many points to Iowa's west. Temperatures in Iowa remain a few degrees below freezing at the time of this image posting. We have a few more days of cold weather left before more mild air returns and a threat of rain.

Cold for early November

13 Nov 2014 05:46 AM
Nothing like getting a bitter reminder of the upcoming winter season with temperatures on Tuesday struggling in the 20s and a brisk NW wind. The featured chart presents the hourly Des Moines Airport temperatures and the most recent date with as cold a temperature for a November 1-15 date. The hours in red are simply dates further back than last year. This stretch of cold weather we currently are in looks to be the coldest since early November 1991.
