March 2015 weather recap: Dry conditions, warm temperatures month’s biggest feature

The month of March was relatively uneventful and lacked any sort of real weather drama.  What was notable was the dry conditions and unseasonably warm temperatures that dominated for the most part.

March started out considerably colder than normal with the first five days of the month seeing temperatures around 20 degrees below normal.  A light shot of snow was recorded on the fourth of the month, a reading that would be our biggest snowfall for the period.

Temperatures began to turn warmer on the sixth with above normal readings recorded through the 16th of the month.  We even managed two 80+ degree days on the 15th and 16th.

Denver actually saw its earliest 80 degree reading in history on the 16th.  The previous earliest 80 degree reading occurred on March 18, 1907.

Unsettled conditions interrupted the warmth on the 25th with a light snowfall and colder temperatures.

We then bounced right back to the dry, mild conditions for the balance of the month.

Thornton’s average temperature for the month came in at 44.9 degrees.  This was well above the long term Denver average of 40.4 degrees.  Out at DIA, the Mile High City’s reading was very similar at 45.0 degrees.

Temperatures in Thornton ranged from a high of 82.6 degrees on the 16th down to a low of 9.2 degrees on the 5th of the month.  At the airport, Denver’s maximum for the month of 81 degrees came on the 16th with its lowest of 2 degrees on the 5th.

Denver officially broke two temperature records in March 2015.  On March 6th the high temperature of 79 degrees broke the record high for the date (previously 76 degrees set in 2013).  Also, on the 16th, the high temperature reading of 81 degrees was a record (previously 75 degrees in 2012).

In terms of precipitation, the rain bucket totals fell well short of the March average of 0.92 inch.  Here in Thornton a mere 0.49 inches was recorded while Denver saw quite a bit more with a measurement of 0.79 inches.

March is historically our snowiest month but that was certainly not the case in 2015.  Thornton snowfall totally only 2.8 inches and Denver was at 2.9 inches. Both were well below the average of 10.7 inches.
