  Month By Month Summary

December kicked off the winter of 2005-2006  with a sharp cold snap to start the month. Temperatures registered at or below normal for 23 consecutive days from the end of November onwards through most of December. Another streak of note occurred during this time, with an amazing 18 consecutive days with at least a trace of snowfall was recorded at the Indianapolis Airport , the longest streak of this kind.

 

 The weather pattern then shifted during the middle part of December, with much warmer temperatures occurring. A truly remarkable stretch of 44 consecutive days with above normal temperatures began at this time, and did not come to an end until the start of February! As a whole, December still ended up as a below normal month for temperatures, as the bitter chill at the start of the month was simply too much to be overcome by late month’s warmth.


Snowfall was fairly abundant during the month of December. Most of it came in the winter’s largest snowstorm on December 7. A quick moving storm dumped 7.7 inches of snow on the airport, most of it coming in just a few hour period. This was one of the heaviest December daily snowfalls on record. The month of December closed out with 14.1 inches of snowfall recorded, compared to a normal of 6.4 inches.  

January began where December left off, extremely warm. After getting off to a warm start, the month never saw temperatures at or below normal. Highs frequently topped the 50 degree mark, and even passed 60 degrees on the second of the month. Residents will long remember this mild month, as it was the warmest January in over 100 years, and the second warmest ever on record. Snow was hard to find as temperatures remained well above freezing most of the time. A normal January would bring 9.3 inches of snow, while January 2006 saw only 2.7 inches in Indianapolis .  

 February saw another shift in the weather pattern, as the string of above normal temperatures came to an end on day 5 of the month, as the high only reached 28 degrees. Following this, the month still saw ups and downs on either end of the spectrum. A sharp warm up came mid-month, as readings passed the 60 degree mark and this warmth brought the first severe thunderstorm event of the season. This was followed by an extremely sharp cool down, with the coldest days of the month coming just a day or two after the warmest. February 18 and 19 both experienced lows in the single numbers, some of the coldest readings of the winter. When it was all said and done, February tallied an average temperature of 32.3 degrees, above normal by 1.1 degrees. Snowfall was again below normal for the month. 3.9 inches fell this year, as opposed to a normal value of 6.1 inches.
