The end of September is here, it is officially fall, and aspen trees are beautifully golden. The super blood moon has risen, and won’t be seen this close again until 2033.
Colorado weather, ending this month, has been mostly nice and sunny. However, nearing October, we are experiencing a mixture of record-level days of hot dry air, increasing wild fire risks, and Colorado is experiencing a number of spring-like thunderstorms. Today, weather services (WXs), forecasted extremely dry Colorado rangeland and forest fire conditions, along with brief front range thunderstorms. Atmospheric models and forecasters were true to their word, as late today, thunderstorms formed along much of Colorado’s front range from Ft. Collins to Denver, from Denver to Castle Rock, and from Colorado Springs to Pueblo.
Several of these late day thunderstorms were National Weather Service (NWS) severe-warned, and one significant severe-warned storm occurred near Golden, Colorado, this afternoon. The Golden storm produced lightning, golf ball sized (1″) hail stones, and had moderate to high winds, peaking around 4:45 pm, mountain standard time (MT). Colorado’s severe-warned thunderstorms were also southeast movers today, and mostly traveled from the northwest to southeast along much of Colorado’s front range. Several of these severe-warned thunder storms did show persistent meso scale rotating updraft towers within the these supercell structures. One such rotating severe-warned storm traveled from northwest of Golden towards southeast of Parker, and diminished a bit east of Castle Rock, Colorado.
Tomorrow, these weather patterns are likely to continue with low 80f degree air temperatures, dew points are estimated to rise to mid and upper 50s, with almost 2,000 CAPE (convective available potential storm energy), along much of Colorado’s front range. We are also likely to see partly sunny skies with occasional afternoon thunder storms, and with the possibility of a few strong thunder storms. This sporadic spring-like monsoonal weather is expected to continue throughout this week. Saturday is predicted to have temperatures drop into the low 60s with increasing monsoonal like rains and increasing thunderstorms.
