 The tail end of the front will stall over the Southeast and will continue to pull moisture in from the Gulf of Mexico. This will allow for periods of heavy rain showers to develop from the Tennessee Valley through the Mid-Atlantic states. Lighter rain showers will develop across eastern Texas and will diminish throughout the day. Rainfall accumulations will range from half an inch to an inch in these areas.
North of this system, high pressure will build into the Great Lakes and Northeast, creating dry conditions and sunny skies with periods of strong winds. The Northeast will remain about 10 degrees above seasonable with highs in the 50s, while the Ohio River Valley and Midwest will start to cool, with highs returning to the 30s and 40s. Farther north, a trough of low pressure moving through central Canada will push even cooler air into the
northern Plains and upper Midwest. High temperatures will reach only into the 20s across these areas.
Meanwhile, out West, a low pressure system moves down the coast of California and will produce a few more scattered showers across
the southern part of California and northwestern Mexico. Snow may develop at high elevations of the southern Sierras. To the north, high pressure builds over the Pacific Northwest, allowing for a break in wet weather for Oregon and Washington.
Temperatures in the Lower 48 states Thursday ranged from a morning low of
minus 9 degrees at Bryce Canyon, Utah, to a high of 82 degrees at Harlingen, Texas.
