Spring officially began this morning at 5:02am MDT. It is during this time, the vernal equinox, that the Earth’s axis is not tilted toward or away from the Sun. As a result equal amounts of the Sun’s light are directed to the Northern and Southern Hemispheres.
Soon after the event this morning one of NOAA’s GOES satellites captured the light on the face of the planet in near perfect equilibrium.
At 7:02 ET on March 20, 2013, Earth was at its equinox. At 7:45 ET, the GOES-13 satellite captured this full disk image of Earth. (NOAA) Click the image for a larger view.

Mar 20, 2013
GOES Satellite Captures Spring Equinox
It is that time of year again (it happens twice) when the relative angle of Earth is perpendicular to the Sun, causing equal incoming solar energy to the Northern and Southern hemispheres – as well as equal day and nighttime. At 7:02 ET on March 20, 2013, Earth was at its equinox. At 7:45 ET, the GOES-13 satellite captured this full disk image of Earth. The visible imagery sensor on GOES requires sunlight to “see” clouds, and so it provides a useful example of the equinox. In this image the GOES imagery extends to each of the poles since the entire hemisphere is equally lit. After the equinox passes today, the Northern Hemisphere will be more lit than the Southern Hemisphere – causing the seasons. (Note: the Sun in this image is artificially created, though the GOES spacecraft does have sensors continually monitoring the Sun for solar activity.)
Northeastern Colorado’s warm, dry winter took a bit of a turn during February as temperatures cooled and we finally received some much needed precipitation.
The month started out with a continuation of the warmer and drier conditions we saw in January. Temperatures for the first days of the month were routinely near or above the 50 degree mark with little precipitation.
That changed on the 9th when low pressure moved through and served to cool things down to below normal. No precipitation was seen however.
The following 10 days were relatively calm and tranquil but with varying temperatures. The month’s high temperature was recorded on the 17th.
As we entered the last part of the month the weather turned much more unsettled and finally delivered a healthy dose of winter. A weak system on the 19th and 20th brought light snow and was followed a few days later by a more significant system on the 24th.
The waning days of the month saw mostly below normal temperatures and one more day of light snow.
The average temperature in Thornton during February 2013 was 30.3 degrees. Out at Denver International Airport, Denver officially had an average of 30.1 degrees. Both were well below the historical February average of 32.5 degrees.
Temperatures in Thornton ranged from a high of 66.2 degrees on the 17th down to the lowest reading of 5.7 degrees on the 25th. Only two days in Thornton failed to climb above freezing.
Denver saw its highest reading of 63 degrees on the 17th and lowest of 5 degrees on the 22nd with six days failing to climb above 32 degrees. All 28 days of the month saw low temperatures below the freezing mark at both locations.
Precipitation was the real weather highlight of February 2013 given how dry the season had been up to then. Thornton recorded 0.71 inches in its bucket while DIA saw 0.77 inches. Average for February is 0.37 so both locations enjoyed above normal measurements.
In terms of snowfall, Thornton measured 11.9 inches of the white stuff. Out at the airport they bested our area with 14.1 inches. Historically February averages a mere 5.9 inches so both were well above normal.

Looking back at January 2013 the numbers reveal a month that wasn’t particularly extraordinary by any measure. Temperatures were slightly below average and precipitation was a bit less than normal.
The first half of the month was notable for cold while the second half for the most part was considerably warmer.
Temperatures for the first three days were well below normal before we entered a brief period with above average temperatures. That was followed by very cold days on the 12th and 13th when high temperatures only reached the teens. Most of the following two weeks were notable for highs in the 50s and 60s.
The month started out extraordinarily dry with a mere 0.3 inch of snow being recorded during the first 27 days. On the 28th though we received a decent little shot of snow to drive up the numbers.
The average temperature for the month came in at 29.7 degrees. This was a full degree below the Denver January average of 30.7 degrees. At the official Denver station at Denver International Airport, the monthly average was slightly warmer at 30.3 degrees.
Temperatures in Thornton ranged from a high of 67.8 degrees on the 24th down to a low of -2.4 degrees on the 15th. Denver recorded a highest temperature of 66 degrees, also on the 24th, and a low of -12 degrees on the 12th.
There were no temperature records set during the month.
In terms of precipitation, an anemic 0.21 inch was measured in Thornton while Denver fared better with 0.31 inch. The January average is 0.41 inch so both locations were a good bit below normal.
Snowfall was similarly light with Thornton recording 3.7 inches, most of which fell during the storm on the 28th and 29th. Out at DIA Denver officially measured 4.6 inches for the month. Average for January is 7.0 inches.
None of the precipitation or snowfall measurements were records.

As we wrap up a January that was pretty much average in terms of temperature and precipitation, we look to February with hope for relief from the dry conditions we have seen thus far this winter. Unfortunately historically February is a relatively dry month but we do start working off winter as temperatures climb.
To date Denver’s seasonal snowfall is 10.8 inches below average and Thornton is even further behind. February though is only the Mile High City’s sixth snowiest month so while we can receive big storms in February, we can’t count on making up much ground.
For those looking forward to milder weather, average temperatures do increase during the month as a sign that winter is fading and spring is approaching.
The 2012 / 2013 snow season has been dismal and while December brought some hope for recovery, recent weeks have seen snowpack decline once again. For the drought and fire weary state of Colorado the data does not bode well.
For the north-central Colorado mountains, the January 22 snowpack is at its second lowest level to date since 1979. Only 1981 saw worse results this far into the season.
According to the latest Colorado SNOTEL reports, the South Platte, North Platte and Upper Colorado River basins are at 57%, 65% and 60% of normal respectively. Statewide Colorado snowpack is a dismal 62% of average.
Is there hope? Mother Nature certainly works on her own schedule so it is possible we could see a recovery. However the latest 3-month outlook from the Climate Prediction Center forecasts warmer and drier than normal temperatures.

In the immediate days following the end of the month most of us are likely to remember the bitter cold that closed it out. However an unseasonably mild start to December 2012 made the month not only finish warmer than average but also drier than normal.
December started out very mild with the first eight days seeing overall average temperatures 12.7 degrees above normal. Colder air moved in after that for a few days before above normal temperatures returned again and continued through the 18th.
Another three day cold spell arrived but mild temperatures returned on the 21st. Christmas Eve ushered in a big chill that lingered through the end of the month.
Overall December’s average temperature in Denver as measured at Denver International Airport was 31.2 degrees. This was 1.2 degrees above the 1981 to 2000 average of 31.0 degrees. Here in Thornton we were closer to average with a monthly average temperature of 30.5 degrees.
Denver temperatures ranged from a high of 69 degrees on the 5th down to a bitter cold low of -2 on the 26th. Eight days failed to reach high temperatures above the freezing mark in the Mile High City and it recorded two days with low temperatures at or below zero.
Thornton saw its warmest temperature on the 1st of the month with a high of 67.6 degrees and its coldest temperature of 00.4 degrees on the 26th. Like Denver, Thornton recorded eight days with high temperatures failing to reach 32 degrees.
Precipitation as recorded at DIA was slightly below normal during December. 0.27 inch was recorded as compared to the average of 0.35 inch. Thornton was unfortunately drier as we only recorded 0.19 inch of precipitation.
Snowfall fell short of average as well during the month. Denver recorded 5.2 inches and Thornton 3.7 inches. On average the Mile High City records 8.4 inches during the month.
With the end of the month, Denver’s 2012 – 2013 seasonal snowfall total falls further behind average. To date it is 8.8 inches below normal. While the snowpack has rebounded considerably thanks to the storms in the latter half of the month, it is currently at 72% of normal.

As we begin the new year the winter chill begins to set in. While January can see its share of extremes, the month historically sees stable temperatures and is usually relatively dry.
January ranks as the second coldest month in Denver next to December with average temperatures remaining virtually the same from the start to the end of the month. In terms of snowfall, the month only ranks as the fourth snowiest and it is not uncommon for it to be quite dry.
What does January 2013 hold for us? Indications are that we may very well continue the recent pattern of below normal temperatures and relatively dry conditions.
As the sun sets on 2012 and the new year dawns, we look back on the past 12 months and can see it for what it was: unusually dry and warm. While we were spared monster blizzards or much severe weather, there were still noteworthy weather events.
In terms of temperatures, Denver recorded an overall average of 53.8 degrees as recorded at Denver International Airport. This was 3.4 degrees above average and put 2012 in the history books as the third warmest year in Denver history. Here in Thornton we were, as usual, a bit cooler with an annual average temperature of 52.9 degrees.
The National Weather Service reported 73 days with temperatures at or above 90 degrees which far exceeds the average of 40 such days we normally see annually. Here in Thornton we too saw more than average with 62 days of 90 degree or hotter temperatures.
The late spring and early summer proved to be record setting in terms of heat. The month of June set a record high temperature average and July was the hottest month in Denver history. Two days, June 25th and 26th broke daily high temperature records and tied Denver’s all-time high temperature of 105 degrees.
On the opposite end of the thermometer, Denver officially recorded 132 days with temperatures at or below freezing. Here in Thornton we recorded two more with 134 days. On average the Mile High City records 157 days of freezing temperatures.
While the year was unusually warm, it was also extraordinarily dry. A mere 10.11 inches of precipitation was recorded in Denver’s rain bucket at DIA, 4.19 inches below normal. Here in Thornton we were even drier as we recorded 9.61 inches of precipitation in 2012. While extremely dry, neither measurement was low enough to make the list of top 15 driest years.
Total snowfall for the calendar year ended up at 38.5 inches at DIA and 35.1 inches in Thornton. Both locations fell well short of the Denver annual average snowfall of 53.5 inches. Denver’s snowfall was enough to keep it off the list of top 15 least snowiest years. However Thornton’s measurement would have made it the 13th least snowiest on Denver’s list.
Snowfall started out reasonably strong thanks to a healthy snowfall total in February. However while March is on average our snowiest month, that did not hold true in 2012. A mere 0.03 inch of precipitation was recorded setting the stage for the balance of a dry year.
Combined, June, July and August recorded only 1.81 inches of precipitation at DIA. This was an astonishing 4.02 inches below average for that period. Thornton fared only slightly better over the period with 2.34 inches.
While September brought above normal precipitation, the final three months of 2012 returned us to drier than normal conditions.
Extreme weather events were not particularly common in 2012. There was a distinct lack of heavy snow events and even spring’s severe weather season was relatively tame.
However, the hot summer temperatures and tinder dry conditions did lead to a deadly and destructive wildfire season.
The High Park Fire in June quickly became the second largest wildfire in Colorado history. That blaze was soon followed by the Waldo Canyon Fire west of Colorado Springs which went into the history books as the most destructive blaze in state history.

For many the holiday season isn’t complete without a chill in the air and snow on the ground. Here in Denver we historically enjoy a better chance of experiencing the proverbial white Christmas than many places in the nation.
How the Mile High City fares in experiencing a white Christmas does depend on your definition of one. If it means having actual snowfall on Christmas Day the chances aren’t that good. However if simply having snow on the ground suffices, the chances improve considerably.
With the first full month of fall here, October usually brings one of the quietest weather months in the Denver area with plenty of mild, sunny days and clear, cool nights.
October is historically the second sunniest month and conditions are generally calm. However we also will usually see our first taste of winter during the month with the first freeze and first snowfall of the season. Temperatures as well will start to drop and by the end of the month the average nighttime lows are below freezing.
As we wrap up a January that was pretty much average in terms of temperature and precipitation, we look to February with hope for relief from the dry conditions we have seen thus far this winter. Unfortunately historically February is a relatively dry month but we do start working off winter as temperatures climb.
