Weather Summary
Weather Underground midday recap for Sunday, March 21, 2010.
Widespread clouds covered most of the Southeast on Sunday as a strong low pressure system trekked eastward across Arkansas. Abundant moisture from the Gulf of Mexico accompanied the system and allowed it to produce swaths of light to moderate rain showers and heavy rainfall with gusty winds and thunderstorms along associated fronts that reached through the Southeast to the Central Gulf Coast and through northern Florida. Colder air filtered in behind this system and translated into an additional mixture of rain and snow from southern Missouri through eastern Oklahoma and northeastern Texas.
Meanwhile to the north, bands of showers in the Ohio Valley moved into New England as a frontal boundary became stalled over the Northeast.
Out West, wet weather developed in the Northwest as a cold front pushed through the Pacific Northwest and into the Intermountain West. Moist flow associated with this front sparked areas of rain and high elevation snowfall throughout these regions, as well as some precipitation in northern California. Meanwhile, onshore flow brought cloudier morning skies and cooler afternoon temperatures to the rest of California. Elsewhere, high pressure continued to produce warmer temperatures with clearer skies throughout the Four Corners.
Temperatures in the Lower 48 states Sunday have ranged from a morning low of -5 degrees at Kremmling, Colo. to a midday high of 84 degrees at Kendall, Fla.
