Late last night we received a quick, light shot of a rain / snow mix. Today, we cool down due to the cold front that caused that.
Sunny skies will be the general rule throughout the daytime hours. It will be calm and dry. High temperatures will reach the low to mid-50s.
Tonight, it will be mostly clear and calm. Overnight lows will be in the mid-30s.
The City of Thornton has announced that it has replaced the old CodeRed emergency alert system with a new one called “ThorntonReady Emergency Alerts.” We highly recommend all residents sign up for the new system immediately.
With the system you can choose exactly which types of events you want to be notified about – civic alerts, weather advisories, weather warnings, etc. Additionally, you control how you want to be notified whether by phone call, text, email or all of them.
We found that they wanted to alert users with an entire gamut of alerts, many which don’t really warrant a middle-of-the-night phone call. However, the ability to be notified about the more common advisories is a nice touch and helps to keep you informed.
For us, we opted out of calls for advisories although being geeks we don’t mind the texts or emails. For calls, we chose only tornado warnings. If you are in an area where appropriate, we would suggest also opting in for calls for flash flood warnings. See attached screenshot of our choices.
Should you desire, you can also add information about your household that could be seen my emergency responders should an emergency arise. These include other members of the household, special health requirements, pets and more.
We chose not to add the personal information at this time as we are somewhat suspicious of what that information could be used for and who it may be shared with beyond first responders.
This service is crucial to ensuing you are notified about dangerous conditions at your home. Please do sign up.

7-8
In 1878…snow from the evening of the 7th until noon of the 8th totaled only 5 inches in downtown Denver. Apparent heavier snow over the plains along with strong winds drifted the snow into high drifts…which delayed trains for several days and caused a great loss of livestock.

In 2000…high winds developed in and near the Front Range foothills…as well as parts of the northeast Colorado plains as another pacific storm system moved across the area. Several trees and power lines were downed near Blackhawk…Boulder…and in Coal Creek Canyon. About 30 homes in the Pinebrook Hills subdivision in Boulder were evacuated when downed power lines sparked a grassfire. The winds eventually shifted the fire onto itself…thus allowing firefighters to contain the two acre blaze. Several roofs were blown off barns…sheds… And garages.

The biannual ritual of changing our clocks to adjust for Daylight Saving Time occurs this Saturday night providing yet another signal of the changing of seasons. The United States will ‘spring forward’ one hour at 2:00am Sunday morning as we begin Daylight Saving Time.
The ritual of changing our clocks twice a year can be met with some resistance as some people struggle to adjust their body’s internal clock. The start of Daylight Saving Time can be particularly problematic given the one hour less sleep people receive on the night of the change.
However, longer days as we head into the milder months are a very real benefit and for many worth the inconvenience of a lost hour of sleep. The time change definitely has big effects on how much daylight we enjoy during our normal waking hours.
On Saturday, prior to the change, sunset will occur at 5:58pm but on Sunday the sun won’t disappear over the horizon until 6:59pm. This affords folks more time in the evening to get started on those spring-time chores and allows us to get outside and enjoy the warming weather.
Similarly, sunrise on Saturday is at 6:23am but shifts to 7:22am on Sunday.
The March Equinox is also on the horizon. Spring officially begins at 8:46am on Friday, March 20.
This year Daylight Savings Time will come to an end on November 1.
Some of the recent history of Daylight Savings Time (from Wikipedia):
Daylight saving time in the United States was first observed in 1918. Most areas of the United States currently observe daylight saving time, with the exceptions being the states of Arizona and Hawaii along with the territories of Puerto Rico, American Samoa, Guam, and the Northern Mariana Islands.
From 1987 to 2006, daylight saving time in the United States began on the first Sunday of April and ended on the last Sunday of October. The time was adjusted at 2:00 AM (0200) local time (as it still is done now).
Since 2007, daylight saving time starts on the second Sunday of March and ends on the first Sunday of November, with all time changes taking place at 2:00 AM (0200) local time.

The month of March in Denver is usually one that is welcomed heartily by residents. We begin to shake off the cold of winter with warmer temperatures and calmer conditions. That does not mean we are done with snow and cold by any means.
March usually offers healthy snowfall giving us an opportunity to add to our seasonal totals. While there is good snow potential in March, the month also typically brings much warmer temperatures.
March is historically Denver’s snowiest month and brings about 20% of our annual snowfall. Heavy, wet spring snow storms can oftentimes bring the entire month’s snowfall total in one monstrous snow.
We also start the transition to spring and severe weather season and the month typically brings our first thunderstorms of the year. Temperatures climb throughout the month and by the end our average daytime highs are near 60 degrees.

The Colorado Front Range’s mild, dry winter carried right into February. Indeed, the month offered up the warmest and driest February of the past 20 years here in Thornton.
A narrative for the month reveals there really was not much to talk about. High temperatures were above average on all but two days during the month. There was no recorded precipitation and the only snow we saw was a trace on the 20th.
Thornton’s average temperature for the month came in at 44.3 degrees. This was far above our 20-year running average for the month of 32.4 degrees. It was also our warmest February on record, easily besting February 2017 (40.1 degrees) as the previous record holder.
For Denver, as measured at Denver International Airport, it was a very warm month as well. The Mile High City’s average temperature for the month cam in at 42.1 degrees. This was well above their long term February average of 32.7 degrees. It put the month in the books as the third warmest February on record.
Precipitation registered a big fat zero for Thornton. This is the first time in 20 years that the month recorded nothing and well below the 0.60 inches we have averaged over that period. Our previous driest February of the past 20 years was in 2009 when we recorded 0.08 inches.
The Mile High City saw a scant 0.02 inches in their rain bucket at DIA. This was far below the long term average for Denver for February of 0.41 inches. It was the second driest February on record.
Obviously, with no precipitation recorded, Thornton saw no measurable snowfall either. We saw one day with a trace and that was it. Our 20 year running average for the month of February is 10.7 inches. This was the first February over that period that no snow was recorded.
Similarly, Denver only recorded a trace of snow at DIA. Denver’s February long term average is 7.6 inches. The month tied the Mile High City’s record for the least snowiest with February 2009.

A very fun celestial event is set for tomorrow morning, but clouds may very well intrude and prevent viewing.
The partial eclipse begins at 2:50am with totality starting at 4:04am and lasting until 5:02am. Our big concern right now is the potential for cloud cover.
At the current time, forecasts show the sky to be mostly clear up until about the time totality begins. Then, we expect a sharp, fast increase in cloud cover with the arrival of a cold front. As such, viewing may be hit or miss.
Set your alarm, get up and take a look, and if clouds are in the way, you are free to go right back to bed. 😀
February signifies the start of the climb toward warmer temperatures for the year. Cold and snow though do intrude but, coupled with milder conditions, there are lots of photo opportunities as can be seen in our monthly slideshow.
The month is one of our least snowiest of the year but it isn’t unusual to see the landscape blanketed in white. Warming temperatures through the month can bring the onset of spring fever and gives residents the opportunity to enjoy some prolonged time outdoors on the mild days.
Cold or mild, snowy or dry, our scenery is almost always gorgeous – and photo worthy.
Showcasing images captured by ThorntonWeather.com readers as well as some of our own, our monthly slideshow covers the entire gamut of weather-related imagery.
Sunsets, sunrises, wildlife and of course every type of weather condition are vividly depicted in images captured from yours and our cameras.
