Residents in Denver and surrounding areas can expect a mild mix of weather this week, with chances of afternoon showers and potential thunderstorms, according to the National Weather Service. The forecast, available on their website, indicates a 30 percent chance of rain and thunderstorms today, primarily after 3 pm, with a high near 79 degrees Fahrenheit.

Tonight's weather is expected to cool down to a low of around 51, with a slight chance of showers and thunderstorms before 9 pm, then possibly extending up to 10 pm. Heading into Tuesday, there's a 20 percent chance of showers after the noon hour, as clouds increase ahead of a high near 80 degrees. Calm winds will become east northeast around 5 mph in the afternoon, so nothing too gusty is anticipated.

As for the rest of the week, Denverites can look forward to sunny and mostly clear skies from Wednesday onwards, with daytime highs landing in the low 80s and nighttime lows hovering in the low 50s. The sunny spell is predicted to continue until Friday night, where the possibility of showers re-emerges.

The National Weather Service also issued a Hazardous Weather Outlook for northeast and north central Colorado, signaling a tranquil start for the week in terms of severe weather events. Scattered showers and storms are expected to develop this afternoon over the mountains, with potential for a few to move onto the lower elevations, the National Weather Service advised in their advisory dated September 28. While no severe storms are expected, there could be small hail, gusty winds to 40 mph, and brief heavy rainfall as they pass. As of now spotter activation will not be needed, but with scattered showers expected, those with outdoor plans should still keep an eye on the skies.
