| A couple of thunderstorms have developed along the higher terrain foothills and Palmer Divide and are expected to slowly move into the District over the next hour or two. Temperature have reached the mid to upper 80s already despite the cloud cover this morning, combined with dew points around 50 degrees, with pockets of mid 50s, should provide enough heat and moisture for moderate to heavy rainfall today. Typical storms motions will be from the SW to NE between 10-15mph, which could help limit some point rainfall amounts. However, additional storms will likely develop along outflow boundaries today, leading to an increased chance of heavy rainfall with localized flooding this afternoon and early evening. The best chance for shower/thunderstorm activity will be in the next hour, lasting until sundown before skies gradually start to clear into the later evening. Storms today may also contain gusty winds, up to 60mph and medium to large hail up to 1.0” with severe storms possible, favoring areas east of I-25 and out on the eastern plains. Overnight conditions will be mild and dry as temperatures drop into the low 60s on the plains with mid to upper 50s along the foothills. Conditions dry out tomorrow with high temperatures jumping back into the 90s. |
WORST CASE SCENARIO: A slow-moving thunderstorm, training of thunderstorms cells or a large thunderstorm complex may result in up to 2.25” total rain in 60-90 minutes.
