Weather Underground midday recap for Thursday, March 21, 2013.
Snow showers moved across the Western states, snow spread across Missouri, and showers and thunderstorms developed across the Southern Plains and into the Lower Mississippi River Valley on Thursday. A broad low pressure system moved over the Rockies and kicked up scattered snow showers across the Northern and Central Rockies. A cold front associated with the system stretched from Montana through Colorado and the Great Basin, which produced periods of heavy snowfall and strong winds. Strongest wind gusts were reported at Monarch Pass, Colorado with a gust up to 147 mph. While this storm was not as strong as previous winter storms this season, winter weather advisories were in effect in these areas as snowfall totals from 4 to 8 inches were observed at highest mountain passes.
At the same time, the leading edge of this system created a front that brought scattered snow showers to Missouri and moved into the Mid-Mississippi River Valley. Most areas saw 1 to 3 inches of snow, with isolated amounts up to 5 inches by Thursday evening. Warmer temperatures to the south of this system allowed for scattered showers and thunderstorms to develop from northeastern Texas through Arkansas and into Louisiana. There was a slight chance of severe thunderstorm development in these areas with main threats being hail and strong winds.
Temperatures in the Lower 48 states Thursday have ranged from a morning low of -18 degrees at Cando, N.D. to a midday high of 83 degrees at Pecos, Texas
