The weather, currently.
Just when you thought it would be just a little chilly... it is going to get colder. Both a low pressure system and a cold front will sweep through Colorado Sunday night into Monday. Most of the time, when a cold front and low pressure system sweep through, we talk about the opportunity for snow in the Denver-Metro along with cold temperatures. This is not one of these cases, and it will just bring colder temperatures. Let me explain:
What determines snowfall in Colorado sometimes depends on the track of the low pressure system. If the center of the low pressure system tracks to the north of the Denver-Metro near the Cheyenne Ridge (near Weld and Logan counties and Fort Collins), Denver is more likely to see snow. If the center of the low pressure system tracks to the south near the Palmer Divide (the terrain area from Castle Rock to Colorado Springs), Castle Rock and Colorado Springs see snow. So for tomorrow, the low pressure system will be too far south and be near the Palmer Divide. That means Colorado Springs and Castle Rock see snow (and maybe Centennial and Parker because they are very close to the Palmer Divide) while the rest of the Metro sees sunny conditions. See! This is why you need a meteorologist trained in Colorado weather, because we know all the ins and outs of what mountain range and terrain do what to the weather here. Weather apps can not do that and it is up to a meteorologist to call shenanigans when we can.
Okay, great, no snow for Denver except some of the southern suburbs. So just cold then? Yep, even though the low pressure system is too far south for the Denver-Metro, the cold front that is coming with it will drop our high temperatures down into the 30s.
Here's an overview of Monday's weather:
1) Morning: Clouds in the morning with temperatures in the 20s through 9 a.m. Sunrise starts at 6:44 a.m.
2) Afternoon: Temperatures will only be in the mid 30s in the afternoon with partly cloudy skies.
3) Evening: By the evening commute, temperatures will still be in the mid 30s with clouds. Temperatures will be back in the 20s by midnight. Sunset starts at 4:46 p.m.
Activity forecast: Now is the time to bring your winter coat with you anytime you are outside. It doesn't matter what time a day you are out. You will need it all day. Exercising indoors is a good option.
Mountain forecast: While Denver misses out on snow, the mountains get to see it! Expect on and off snow showers on Monday. Temperatures will be in the teens in the morning and low 30s in the afternoon.
What you need to know, currently.
There will be widespread below-average temperatures in much of the lower 48 states, according to Currently’s Chief Meteorologist, Megan Montero.
High temperatures will be 10 to 20 degrees below average, as the cooler temperatures hail from a cold front that made its way across the nation this weekend.
“Locations as far south as the Gulf Coast and Florida panhandle will dip into the 30s during the overnight hours of Sunday and Monday,” Montero said.
Freeze warnings are also in effect across central Texas and the Southeast though Sunday morning.
This is an interesting turn of events because while heat waves and cold spells are a natural part of day-to-day weather variation, heat waves are expected to become more frequent and intense as the Earth’s overall climate warms, while cold spells are expected to decrease.
According to Montero, scientists expect daily minimum temperatures to become warmer at a faster rate than daily maximum temperatures, which will leave less opportunity to cool off and recover from daytime heat.
“On its own, this event isn’t out of the ordinary, [but] something like this will be more infrequent as time goes on,” Montero said.
