Yesterday saw a rebound to above normal temperatures but today and the first part of this week we see a return to cooler conditions.
Monday we start out with the breezy winds from last night continuing initially but then settling down. There is a good bit of moisture aloft and that will lead to partly sunny skies today. Temperatures will be topping out around 82 degrees, a bit below the average for the date of 85 degrees.
The afternoon brings just a slight chance for some isolated thunderstorm activity.
So who is ready for some snow? Along with many other notable weather events, it was this week in Denver history when we received our earliest snowfall on record!
From the National Weather Service:
In 1875…grasshoppers appeared in great numbers at 10:00 am on the 19th. Thousands landed on the ground. The streets were literally covered with them. Swarms of grasshoppers were seen on each day.

In 1985…severe thunderstorms dumped heavy rain and hail at many locations along the Front Range from Denver south. The southern and eastern suburbs of metro Denver were especially hard hit. Rainfall from 1 1/2 to 3 inches caused extensive street flooding in Aurora where two creeks rose out of their banks. Two homes in the city suffered minor lightning damage. Almost 4 inches of rain fell in the Parker area. Hail up to ping-pong ball size piled up to a foot deep and closed a road in Evergreen. Hail as large as 1 3/4 inches in diameter was reported 8 miles northeast of Deckers. Wind gusts to 65 mph were estimated in southeast Aurora.

We start out the three-day period with a day similar to yesterday but with warmer temperatures. That will be followed by drier conditions and increasing mercury readings.
For Friday, we start out with a good bit of cloud cover and will see that slowly erode through the day. By this afternoon partly to mostly cloudy skies will be above. Some scattered shower activity will be possible this morning then this afternoon we see a chance for thunderstorms. Temperatures will be warming to a high in the mid to upper 70s.
Saturday continues the warming and drying. Mostly sunny skies will be above as we head for a high in the low to mid-80s. The afternoon will bring just a slight chance for thunderstorms.
High pressure builds on Sunday and that will lead to our warmest day of the period. Highs will be in the mid to upper 80s. At this time, it looks like we will remain dry on that day.
Looking beyond, a high pressure ridge looks to be the dominate feature and that will bring above normal temperatures and dry conditions for at least the first part of the next workweek. Have a great weekend!
PESCARA DEL TRONTO, Italy — Strong aftershocks shook earthquake-ravaged villages in the mountains of central Italy on Thursday, with rescue teams dodging falling debris and bleary-eyed survivors still holding out hope that loved ones might be found beneath the rubble. The provisional death toll seesawed overnight, first reported to be nearing 250, then revised downward to… » Click here to read the rest of Aftershocks shake central Italy after earthquake that killed 241
We managed to eke out a tenth of an inch of rain from yesterday’s showers. Not much but it is better than nothing. Today the weather looks somewhat similar to yesterday with a decent chance for showers but with a bit warmer temperatures.
We start out the day with mostly sunny skies above followed by a gradual increase in cloud cover as the day progresses. The sun we do get will help warm us to a high in the mid-70s.
After noon we begin to see slight chances for showers and thunderstorms. As the afternoon progresses, chances increase with the best opportunity coming from 4:00pm into tonight.
A newly discovered, roughly Earth-sized planet orbiting our nearest neighboring star might be habitable, according to a team of astronomers using the European Southern Observatory’s 3.6-meter telescope at La Silla, Chile, along with other telescopes around the world. The exoplanet is at a distance from its star that allows temperatures mild enough for liquid water to… » Click here to read the rest of ESO Discovers Earth-Size Planet in Habitable Zone of Nearest Star
AMATRICE, Italy — A devastating earthquake rocked central Italy early Wednesday, collapsing homes on top of residents as they slept. At least 37 people were killed in hard-hit towns where rescue crews raced to dig survivors out of the rubble, but the toll was likely to rise as crews reached homes in more remote hamlets. “The… » Click here to read the rest of At least 37 dead after devastating quake hits central Italy
With the passage of a cold front and a trough digging in, Thornton will see notable changes in our weather Wednesday. The mercury will stay some 10 degrees below normal and maybe, just maybe, we will see some precipitation.
Mostly cloudy skies will be above throughout the day today. Look for highs to top out in the mid-70s, well below the average of 86 degrees for the date.
Some light showers will be possible this morning with the best chances coming between 9:00am and 11:00am. Then, this afternoon, heating should help bump up instability and bring chances for thunderstorms, particularly after 4:00pm. Unfortunately there isn’t a whole lot of moisture with this system but with any luck we will eek out something measurable.
