The National Weather Service in Denver is keeping an eye out for storms as variable weather conditions continue to sweep across Colorado, with an increased likelihood of thunderstorms bringing potentially hazardous conditions. Today's forecast indicates a 50% chance of showers and thunderstorms in the afternoon, with a high near 86 degrees and north winds that could gust as high as 17 mph, according to the National Weather Service. Denver residents should stay alert for sudden weather changes, including gusty winds and scattered showers.

As we move into the night, the chances of showers and thunderstorms will dip down to 50% before 9 pm, and temperatures are expected to lower slightly around 62 degrees, while Thursday is set for an increased chance of precipitation at 70% with thunderstorms likely occurring between noon and 3 pm, then likely afterward as well, and the weekend forecasts hint at high temperatures possibly breaching into the triple digits across the plains despite some remaining chances of showers and storms. Although the wet conditions might be a minor hindrance, the soaring temps forecasted have likely Denverites bracing for a true summer swelter.

Concerning the hazardous weather, the NWS statement advised that thunderstorms will be more numerous this afternoon and evening, and highlighted that the main threat from the storms will be locally heavy rain. They've warned that some areas might experience 1 to 3 inches of rain within a couple of hours, which could be particularly problematic in the foothills later in the day and areas with burn scars and urban infrastructure are at increased risk of flooding; the strongest among these cells are capable of churning out 50 mph wind gusts and hail up to an inch in diameter.

Spotter activity is not anticipated for today or tonight, however, NWS values reports concerning heavy rainfall or flooding, as these bits of information assist in assessing the impact of storms processes adapting as the weekend promises more sun and less rain, the locals anticipate sweltering conditions that invite a shift toward cooling endeavors rather than the rain-preparedness of the current days, even as the heatwave brewing just beyond the precipitation carries its own set of challenges.
