| Light to moderate rain from 0340Z to 0430Z (8:40p-9:30p). Then, according to my home weather station, light to moderate rain from 0540Z to 0615Z (10:40p-11:15p). Due to the high winds, all precip evaporated in my tube. I also had a large branch from a dead tree fall in my back yard - about 4-5” in diameter. This happened overnight, after the cold front came through. For what it’s worth, my home weather station measured .05”. It often trends on the higher side when comparing it to my official gauge measurements, but sometimes will match. |

| Though high wind alert predicted around 11 am, winds did not begin until midafternoon. Sunny, pleasant morning, high mid 60s. Dark heavy shelf clouds formed around 2 pm and high winds began about 345 pm Winds were unbelievably fierce til about 330 am. Sounded like freight trains. Unsure of wind speed or gusts but similar to experince in Japan where wind speed reached 70 mph. Cooler today - 49 but warmer temps ahead and another high wind alert for Friday. Though EXCEL Energy planned to shut down power for many counties along the Front Range, here in Longmont we have buried lines - what a gift. |
