Dry conditions were forecast to return to the West Coast, while the Southeast remained wet and stormy Tuesday.
A trough of low pressure was expected to continue strengthening as it moved eastward across the Southern portion of the country. The system would obtain energy and moisture from the Gulf of Mexico, allowing for scattered showers and thunderstorms to develop as it hovered over the Lower Mississippi River Valley. This system does not have a history of producing severe weather, but forecasters said may trigger some significant storms Tuesday afternoon and evening. The front associated with this system was capable of producing over 2 inches of rain. Cool air would move in behind this system and drop highs into the 60s, whereas the southern side of this front was expected to remain in the 70s and 80s.
In the North, a trough of low pressure was forecast to dip into the Great Lakes from Canada. Due to cold temperatures in the North, this system may produce some light snow across the Northeast and east of the Great Lakes. However, most areas were expected to see light rain showers throughout the day as highs remained above freezing.
In the West, a trough of low pressure and associated cold front that kicked up some heavy rain would pull northward and into British Columbia. At the same time, high pressure was forecast to build in from southern California, which would dry out the atmosphere, bringing mostly sunny skies and seasonable temperatures.
Temperatures in the Lower 48 states Monday ranged from a low of 17 degrees at Bear Lake, Idaho, to a high of 96 degrees at Laredo, Texas.
