Current Weather in Hesperus, CO

Sunday's weather is significant with Post-Tropical Cyclone Rachel bringing heavy rain to Southern California, Nevada, and Utah. Possible rainfall could reach over three inches in the mountains. The potential for flash flooding is high, so folks in these areas should remain vigilant. This rain is driven by leftover moisture from the cyclone meeting a frontal boundary. By Monday, rain will still be a concern until the system weakens.

East Coast: Over Sunday and into Monday, Post-Tropical Cyclone Isaias is moving toward the central Appalachians, bringing showers and thunderstorms to the Mid-Atlantic and Northeast. Rainfall could lead to scattered flash flooding as Isaias heads back out into the Atlantic by Monday. Look for another round of rain, but less intense, by Tuesday with no major flooding expected.

Northern Rockies: Our first winter storm of the season is rolling into the Northern Rockies over the weekend, mainly affecting Montana. Here, cold air from the north is turning rain into snow, especially in the mountain regions, where snowfall could surpass a foot by Monday afternoon.

Central U.S.: Temperatures are unusually warm through Monday, with highs in the 80s and 90s across the Northern and Central Plains, even threatening daily records. Meanwhile, a cold front in the West will bring cooler 40-degree temperatures to the Northern High Plains on Sunday. In the Southeast and Northeast, temperatures will be more average, with 70s in the Southeast and 60s in the Northeast, influenced by cloud cover and rain from Isaias.
