Heavy rain in the mountains while the I-25 corridor and Plains remain mostly dry and mild

Deep subtropical moisture is getting pulled into the Four Corners this afternoon, increasing a widespread heavy rain threat across much of the mountains. A Flood Watch is in effect for the San Juans, although isolated flooding and mudslides are possible across the Continental Divide. Across the eastern Plains and I-25 corridor, mostly dry conditions persist under mostly cloudy skies. Temperatures overnight remain very mild for late October and will fall into the 50s for most.

Thursday will bring more chances for heavy rain across the Continental Divide, with some sunshine and above-average temperatures again for most. Temperatures will warm into the 60s, 70s, and even mid-80s for the mountains, I-25 corridor, and eastern Plains, respectively. An isolated shower or thunderstorm will be possible by Thursday afternoon in the vicinity of I-25.

Friday will be the last day with well above-average temperatures. As the core upper-level low moves in, chances for showers and thunderstorms will be area-wide. By Saturday, this system will drag a cold front through, quickly decreasing temperatures for the weekend. Chances for rain continue Saturday, but could increase dramatically for Sunday, as a cooler, wet end to the weekend is expected. As colder air wraps in, some snow will be possible, mainly for higher elevation communities.
