Two storm systems will continue to bring unsettled weather to the Lower 48 through the middle of the week. Heavy to excessive rainfall may lead to flash flooding over portions of east Texas into the lower Mississippi Valley Tuesday into Wednesday. Severe thunderstorms are possible from portions of the southern Plains into the lower Mississippi Valley Tuesday. Read More >
Overview
|
A potent late season winter storm brought winter back in full force for much of the region with significant snowfall in many mountain locations and heavy rainfall to the lower valleys. Plenty of moisture and a powerful cold front accompanied this system which lowered snow levels down to some valley floors including Montrose, Colorado (elevation around 5700 feet) where snowfall amounts of 3 to 6 inches were measured near town. This storm became an intense upslope snowfall event with some of the northern Colorado mountains receiving near or in excess of 2 feet! While the cold front had worked through the region by Thursday morning (May 18), impressive wraparound moisture kept showers falling through Friday evening (May 19) before drier air finally worked into the area from the west. Travel was impacted over a majority of high elevation roads where snowpacked and icy conditions developed with periods of reduced visibility due to blowing snow. Areas along Interstate 70 were greatly impacted with portions of the interstate being closed near Vail Pass due to multiple spun out vehicles. The cold air that filtered into the region behind the front resulted in a drastic decrease in temperatures with daytime highs cooling some 20 degrees and overnight lows plummeting back below freezing for many lower valleys. These subfreezing temperatures were a big wake-up call for early blooming, sensitive vegetation in areas like the Four Corners and Upper Dolores River Basin. |
