annualtemperature2014The preliminary temperature data for Springfield for last year is in and we were cold.

Out of 127 years of record keeping in Springfield, our average temperature was 55.3°,  This works out to be the 40th coldest on record.

The coldest year on record occurred in 1979 at 53.4°. The warmest year was 1938 at 59.6°.

The graph above shows the annual average temperature for the past 127 years.  Also indicated on the chart is the linear temperature trend and the 10 year running or moving average.

It’s interesting to look at this annual data.  While I put a linear fit line on the graph, one should note that the R-squared value is .02 which is awful for expressing anything meaningful for noisy and non-linear data such as this.

The blue line is a 10-year running “average of the averages” which is easier to follow and clearly shows our most recent warming (since about the late 1970’s) and the other major warming and cooling trends over the past 127 years

Despite highs in the seventies on the final two days of November, Springfield managed to place 9th coldest on record.  We recorded an average temperature of 40.9°.

There are two sets of years which were tied. The years 2000 and 1996 tied for 4th while 1926 and 1911 tied for 7th.


Thanks to a long-lasting cold wave in the middle of the month, November is projected to rank in the top ten coldest on record in Springfield.

While the cold stretch only broke one record low, several cities in the Ozarks experienced record cold highs from the period of the 11th through the 18th.

It will be remembered for one of longest stretches of high temperatures below 40° recorded in November since records began in 1887.  Springfield pieced together seven such days this November which ties runs in 1937 and 1898.  The cold snap in 1937 was colder but like this years, it occurred right before Thanksgiving.  Be sure to look through the images above!

I projected our temperatures forward to Sunday, November 30th, and we are coming in with an average temperature of 40.5° for November  This would be a tie for 8th place in the top ten coldest Novembers on record if the forecast numbers are accurate.

Any slight warming above the forecast numbers could just bump us out since the numbers are crowded around 9th and 10th place.  Nevertheless, a cold middle of the month anyway you look at it!

novcoldRecord lows were broken in the Ozarks this morning as the area begins to pull out of the wave of cold air which arrived last week.

Springfield fell to 9° this morning, breaking the old record of 13° dating back to 1903. Joplin dropped down to 6°, also a new record for the date and was the coldest low ever recorded in November. West Plains and Rolla (Vichy) broke records this morning as well.

As a nation (at least the lower 48 states), this mornings’ mean temperature dropped to 19.4°, the coldest November day since 1976!  (see link below for more information)

Since Tuesday of last week (11/11), the high temperature in Springfield has stayed below the normal low for this time of year.  All readings have been in the thirties except for Monday the 17th which only saw the thermometer climb to 25°.

Today is another cold day with a forecast high right around freezing.  Starting on Wednesday, warming begins in the Ozarks as high temperatures climb into the forties.  Forties will last the rest of the week. While warmer, these readings are still below normal.

While the weekend will warm into the fifties, more chilly, below-normal air will move into the Ozarks for the beginning of next week.

Past Thirty Days of Rain

Past Thirty Days of Rain

It’s not too hard to see why the drought has been eliminated over the Ozarks as seen on the latest Drought Monitor update.  Just compare the drought map to the rainfall accumulation over the past thirty days.  The rain belt matches the non-drought belt pretty well!

The weather pattern has changed since that wet period ended.  We have gone the longest number of days without rain in Springfield (10 days as of today, Thursday, 8/22) since back in late June with more dry days in the forecast!

I’m sure you remember but last July was hot!  The month registered 12 one hundred degree days (17 total for the summer).

There was also a crop of record high temperature in July of 2012:

Record Highs 2012

Record Highs 2012

By sharp contrast, July of 2013 contained no one hundreds and no records. We had several hot spells but finished the month very cool.

Just looking at high temperatures, July of 2012 had an average high of 97.6°  In July of 2013, it was only 86.8°.  In climate, a drop in average of over 10 degrees is striking!

The pattern of hot last year lasted into about the first 10 days of August before it finally broke. This year, August will start at or just a smidge below normal.

June Comparisons: 2012 vs. 2013

By this time last year, the 100 degree heat had begun, a pattern which would last all summer.

By comparison, I have a significant cool-down in the forecast which will put readings more than 20° cooler than last year for the closing days of June 2013.

Here is a neat little slider I put together to easily compare the two months. I’ll update this chart daily, it will be more striking by Monday!
