July 2012 Temperature Departure

August is here, July is behind us and of course, it was very hot and very dry!

Most of the Ozarks came in 5-6 degrees above normal.  Springfield Missouri recorded nine record high temperatures and and few record high low temperatures as well.  All of the major reporting stations in the area reported similar stats.  Springfield’s hottest day was 106°. West Plains reached 107°, Joplin hit 109° and Rolla topped out at 104°

Clouds and sprinkles on the last day of the month almost kept temperatures “cool” enough to change our average temperature ranking but with a high of 95°, our average temperature climbed to 84.3°.  The chart included shows the ranking of this July and it looks like fourth (preliminary numbers).  July of last year was just a touch hotter.

July 2012 Temperatures

It was a dry month. Ironically, the most rain fell in the driest areas of the Ozarks but of course this was still way below normal and barely put a dent in the extreme drought conditions.  Rainfall was spotty and generous to a select few area. Rolla (Vichy Airport) had a total of 4. 85″, most of that falling in two rain episodes early in the month. In striking contrast, Joplin had on a trace of rain!!  Springfield only recorded about a third of an inch of rain. making it the driest July on record.

Apr 012012

March 2012 was the warmest on record! With an average temperature of 58.1, we beat out the old warmest March in 2010 by a half of a degree.

Just looking at the temperature graph, it was pretty incredible. We had 4 days eighty and above. 15 days in the 70’s It only dropped to freezing or lower 8 times, all in the first 10 days of the month.

A record high was tied on March 13th at 82 degrees. It was a very warm week. Humidity flowed freely from the Gulf of Mexico but a lack of fronts or strong weather systems aloft meant rain and storms were rare and random. There was a pocket of rain and hail to the east of Springfield on the 13th.

The “wet week” started as a push of powerful jet stream winds made its way into the central U.S. I took advantage of the Gulf humidity and the fast jet stream winds to go on a storm chase to Oklahoma on Sunday the 18th. Eventually, this system would “cut-off” and slowly move over the south central U.S. and in fact track right over the Ozarks. We were for the most part spared of any severe weather (there were a few isolated wind reports) as this system first started affecting the area. It was mostly a heavy rain producer.

Precipitation fell as all rain expect for a trace of snow on the 8th. Most of the Ozarks had above normal precipitation (insert), thanks mostly to the mid-month low mentioned above. Areas of northern Arkansas, and extreme southern and southwestern Missouri had between 6-8 inches of rain for the month on average with locally much more.

Springfield Temperatures Winter 2011-2012

As you already know, no snow! Or very little this winter 2011-2012.  Can it snow in March? Yes. Will it? Not likely!  The pattern into the middle of March looks quite warm.


Winter goes in the record books as the period of December, January and February.  In Springfield, all three winter months recorded above normal temperatures.

There were a total of 14 sixty-degree high temperature days over our winter months with the highest reading of 69 occurring in January.

Our coldest mornings, 10 degrees on both days, came to us on the weekend of February 11/12 (right before the “snowstorm”)

Missouri as a whole recorded its third warmest winter on record going back 117 winters.  Most of the country was above normal with many states in the northern and northeastern U.S. within the top five warmest on record.

The lower 48 states recorded the 4th warmest winter on record and the warmest since the year 2000.


The snow total stands at 2.8″ which is in a tie for second on the least snowiest winter list with winter 1931-1932. Nearly all of the Springfield snowfall came on two “events”: a post cold front on January 11/12 and what I would classify as the only storm of the season on February 13th.  The February system dumped over 5 inches of snow to locations east of Springfield but only officially accumulated to 1.7″

In terms of precipitation, Springfield came in at 6.15″ which is on the dry side of normal by 1.88″

February 2012 Temperatures

We had some snow in January but what we got in February actually resembled a storm.  Still, with a winter season snowfall of 2.8 inches, winter has been virtually snow-free for the Ozarks.

The month had a definite cool snap but was still ended up way above normal.    As in January, February had a few sixty-degree days, a total of 7.  The warmest day of the month was on the 23rd reaching 68 degrees.  The month ended up 3.5 degrees above normal.

The coldest blast of weather so far this winter came in on a strong high pressure system on the weekend of the 11/12th.  Both mornings recorded a low of 10 above.  This cold air was the set-up for accumulating snow on Monday the 13th.

The snow on that Monday was not a classic low pressure system.  Southerly winds dominated throughout the event.  Springfield picked up 1.7″.  The blog for the snowstorm of winter 2011-2012 is here.  Our seasonal snowfall total stands at 2.8″  This is a tie for second for least snowiest seasons on record with the season 1931-1932.

The month actually ended up slight above normal in precipitation. The major precipitation hits were on the 3rd, the 15th and the 29th.

Of course, the biggest story of the month was the leap day outbreak of tornadoes.  This story is still being written. I will continue to blog about this and the Springfield National Weather Service will fill in more information on their web site as it continues to come in.

January 2012 Highs and Lows

What a warm month!  The Ozarks, and indeed much of the U.S., experienced a much above normal temperature pattern in January.

Our warmest day was 69 degrees on the 16th. Six days out of the month saw highs of sixty or higher. Our average temperature for the month ended up at 38.1 degrees or 5.5 above the normal (1981-2010)

Snow No-Show

The only measurable snow came on the 11th/12th when Springfield measured most of its season snowfall to date with 0.7″  This fell in the wake of a strong push of cold air. It was a Thursday. (sorry, channeled Forrest Gump there for a second)

Remember That Thursday?

January 12th was a cold one!  Howling northwesterly winds produced wind chills that dropped below zero at times.  The high on the 11th was 56 while the high on the 12th only reached 26 degrees, which was not achieved at the normal late-afternoon time !

The snow kept reinventing itself with each new little batch adding just a touch more to the accumulation total.  Some areas did pick up more than an inch of the white stuff.

Some Cold

We got down to 13 twice this month and our coldest morning was 11 on the 18th. The most significant cold fronts passed through on the 11th/12th and on the 17th/18th.

January Precipitation Total

Not Much Precipitation

The most significant rain system came our way on the 25th. Areas of northern Arkansas exceeded two inches of rain. Otherwise, it was a dry month over the area, especially in Missouri.  Springield ended up about an inch and one half below normal.

Wind Was a Factor

It was fairly breezy in January.  The peak wind gust exceeded 30 mph on 9 of the 31 days in January.  Our peak gust was 40 mph on the 22nd.

We Had Tornado Warnings!

Many of you likely slept through it.  It only affected a small portion of the Ozarks and it happened during the late evening and overnight hours. Our only run-in with spring-like weather came on started on late Monday evening the 16th and ran into the early morning hours of the 17h.
