Storm Impacting the Northwest U.S.; Fire Weather Conditions in Southern California; Severe Weather in the South

A Pacific storm is bringing areas of low elevation rain, moderate to heavy mountain snow, and high winds to the Northwest. Strong Santa Ana winds and very dry conditions are producing elevated to critical fire weather conditions in southern California. Isolated strong to severe thunderstorms are possible through early Wednesday morning across parts of northeast Texas into western Tennessee. Read More >

Winds will increase late this morning into the afternoon as a stronger jet stream moves in on the southern edge of a upper level trough moving across the northern Rockies states. Expect strongest winds to occur over northwest Colorado and areas along I-70 in west-central Colorado where winds will gust to 45 mph or greater at times. A wind advisory is in effect for those areas as shown in the map below from 11 am MDT through 9 pm MDT today. Generally winds will be gusting 30 to 40 mph elsewhere. Much drier conditions are expected across east-central Utah and portions of west-central Colorado including Paradox Valley where critical fire weather conditions will be met. Therefore, a Red Flag Warning is in effect for those areas. Breezy conditions will continue into Tuesday but will be less windy than Monday.
