As the month of March begins, weather patterns across the U.S. continue in place, with the Northeastern and Atlantic Seaboard remaining cool while a much warmer than normal weather pattern persists over the far Southwest.  Changes will take place during the coming ten day period with western storms to bring cool, even sometimes wintry weather to the inter-mountain west and portions of the high plains.  The trough of low pressure responsible for this inclement weather will move eastward by the middle of March, allowing the first signs of a heat-dome-warming weather pattern to frequent the far west.  The ‘Ides of March’ will find California and the U.S. Southwest in the grips of unprecedented high temperatures along with dry conditions.

The heat dome will work eastward later in March to include much of the Southern United States.
