Lots of sun, mild temps for Thornton’s Thursday

Thursday, November 3rd, 2016 5:00am MST

Our cool-down yesterday made for a nice change but it was short-lived. Today we bounce right back to the unseasonably warm temperatures that have dominated our weather in recent weeks.

We start out the day with sunny skies and they will last throughout the day. It won’t be till this evening when we may see just a cloud or two. The morning starts out chilly due to those clear skies but we will see the mercury rise steadily through the morning. Look for highs today in the upper 60s.

Similar mild temps can be expected through the weekend although we will see more clouds over the period.

Thornton’s Wednesday cools further, remains dry

Wednesday, November 2nd, 2016 5:21am MST

We’ll be seeing mercury readings closer to normal today although still above average for the date. Overall conditions will be calm and still dry.

We start out with a healthy dose of cloud cover to be followed by gradual decreasing coverage. By late afternoon we should have a good bit of sun.

How quickly the clouds dissipate is going to be a driving factor in our temperatures today. Right now we would expect a high in the low 60s but should the cloud cover ease sooner, it will be warmer. As you would expect, we will remain dry.

We’ll be warming back up after today with temperatures in the upper 60s expected through the weekend. More details in the extended forecast here.

Tuesday cools a good bit but temps remain above normal

Tuesday, November 1st, 2016 5:10am MST

With cooler air filtering in and some additional cloud cover, Thornton will see the mercury settle down a bit today. Overall conditions will remain dry and calm.

We start out the day with a bit of cloud cover courtesy some mid and upper level moisture. Look for mostly sunny skies overall to prevail today. Temperatures will be climbing to a high of around 66 degrees, still a good way above the average of 59 degrees but also considerably cooler than yesterday’s record-tying temperature.

Denver ties record high temperature for Halloween

Monday, October 31st, 2016 5:08pm MST

Record High TemperaturesThe month of October is ending the same way it has been the majority of the month with above normal temperature readings.  Denver has in fact tied the record high temperature for Halloween making it the fourth record high temperature set this month.

At 12:24pm the National Weather Service reported 79 degrees at Denver International Airport. This typed the record high for October 31 last set in 1950.

Here in Thornton we were just a couple degrees warmer with a high of 81 degrees at 3:12pm.

Today’s record-tying reading follows three record high temperatures set earlier this month on October 15th, the 27th and the 28th.

Halloween brings very mild temps, a bit of wind

Monday, October 31st, 2016 5:05am MST

Looking for a chance in the mild, dry weather? It isn’t going to happen today with the only difference between today and recent weeks is a bit of wind thrown in.

We will start out the day with mostly sunny skies and similar sky conditions can be expected throughout. Winds will be calm initially then pick up speed by mid-morning. Look for it to be pretty breezy with gusts to 25 mph or so this afternoon. In terms of temperatures, it will once again be quite warm as we head for a high in the mid-70s, well above the average for the date of 59 degrees.

The winds will die down toward this evening and trick-or-treat time should be quite pleasant.

Note: The wind in the graphic below is not correct.  It should read “NW 12, G 26.”

No October snow in Denver? Not unusual at all

Saturday, October 29th, 2016 4:25am MST
The lack of measurable snow this October is not all that unusual. Click for larger view.

The lack of measurable snow this October is not all that unusual. Click for larger view.

October will end with Denver not having seen any snow accumulation at all during the month.  While that, coupled with the overall lack of precipitation is concerning, not having snow is not at all unusual.

On average, the Mile High City receives 4.2 inches during October.

However, since record-keeping began in 1882, the month failed to yield any snow at all in 19 years since.  Further, in another 17 of those years we only received a trace.

This means that in 27% of the past 134 years, we saw essentially no accumulating snow in October.  So, the fact we won’t have received any this month is not uncommon.

The average date for our first snowfall is October 18th so we aren’t running all that far behind.  The earliest seasonal snowfall came on September 3, 1961 and the latest on November 21, 1934.

We have been exceedingly dry, really since the first part of June.

In October, Denver has recorded a mere 0.26 inches of precipitation while here in Thornton we have fared better with 0.43 inches.  On average we expect to see 0.97 inches so both locations are well below normal.

Perhaps more notable than the lack of moisture is the temperatures which have been unseasonably warm.

As of right now, the average temperature for the month is at 57.2 degrees in Denver, 55.1 degrees in Thornton.  This is running far above the historical October average temperature of 50.9 degrees.

Depending on temperatures between now and the end of the month, it is looking likely that October 2016 will finish somewhere in the top five or six warmest Octobers on record.

Back to back: Denver sets a record high temperature for second day in a row

Friday, October 28th, 2016 4:21pm MST

Record High TemperaturesFollowing on yesterday’s record-setting performance, the mercury once again rose to levels never before seen on this date.

At 12:53pm the station at Denver International Airport reported 82 degrees.  This easily bested the previous record for October 28 of 80 degrees last set in 1994.

Here in Thornton we were actually a bit warmer reaching 83 degrees at 3:34pm.

This is the third record high temperature recorded this month.  The first came on October 15 and the second just yesterday.

At this time it is certain that October 2016 will go into the record books as one of the 10 warmest Octobers in Denver history.  Where it ends up on the list is yet to be determined but it is likely to be around the fourth or fifth warmest.

Thornton’s weekend to see continued warm, dry weather conditions

Friday, October 28th, 2016 4:59am MST

The waning days of October are set to bring more of the same unseasonably warm and dry weather we have seen for the past few weeks. Friday once again has the potential to see record highs before we cool down just a bit Saturday and Sunday.

For today we will have a good bit of cloud cover due to upper level moisture coming from the southwest. That however will not translate into precipitation and we will be dry. Temperatures today will be greatly dependent on the cloud cover’s influence. We may top out at or just a bit above 80 degrees but if the clouds provide enough coverage, we may stay in the 70s. The record high for today’s date is 80 degrees, last set in 1994.

Saturday is going to see a bit more sun and slightly cooler temperatures. Look for mostly sunny skies above as we head for a high in the mid-70s.

We’ll close out the weekend on Sunday with a day much like Saturday. Calm, dry and mild conditions will continue.

Have a great weekend!

Denver sets new record high temperature for October 27

Thursday, October 27th, 2016 5:39pm MST

Record setting high temperatures in Thornton.For the second time this month, the Mile High City broke a record high temperature.  The new mark beats a reading that had stood for 50 years.

At 3:23pm today the mercury at Denver International Airport topped out at 83 degrees.  This easily bests the previous record for this date of 80 degrees last hit in 1966.

Here in Thornton we were just a notch cooler with a high of 82 degrees.

This is the second time this month Denver set a record high. The first came on October 15 with a reading of 85 degrees that beat the previous mark of 83 degrees.

We may not be done setting records either.  The record high for tomorrow is 80 degrees as well, set in 1994 and years prior.  Right now the forecast calls for us to reach that same temperature although cloud cover may prevent that from happening.
