Weather across America

(NATIONAL) Flooding potential across the Pacific Northwest and Southeast should wind down, much above average temperatures to continue across the central and eastern U.S., and critical fire weather expected for the Southern High Plains.

The risk for flash flooding will dwindle down after Sunday and much quieter weather should be expected across the Pacific Northwest and Southeast. Areas in the southern U.S. should be mostly dry for Monday and Tuesday as high pressure dominates the weather pattern and the cold front continues to slide southeastward. Florida may see the chance for rain linger into Monday and Tuesday as the front is forecast to stall over the region and keep low level moisture present. 

The Pacific Northwest will see the frontal boundary sweep through the area and the cooler, stable air mass should prohibit any deep moisture plumes, but showers are still likely off the Pacific. It will be rather cool with highs in the 40s and 50s. The next big weather storyline is the very warm temperatures across most of the southern and eastern portions of the country. Ridging over the Southwest U.S. will keep most of the Southwest toasty for late December standards with highs in the middle 70s across California and Arizona and highs nearing or breaking 90 into central Texas. 

The Southeast will see highs in the 60s and 70s despite a weak cold front passage. Temperatures will begin to cooldown by the middle of the week. The Storm Prediction Center has parts of the southwestern Plains under a critical fire weather outlook. Conditions will be favorable for fires as a developing low pressure and frontal system provide strong, gusty winds atop dry soils. Listen to local officials on fire weather safety. 

Parts of the Transverse Mountains in California are under an elevated fire weather risk due to high winds and low relative humidity. 

Elsewhere across the nation, a low pressure system will continue to track northward across the Ohio Valley on Monday and provide showers and storms along the cold front before exiting the coast Tuesday. A cold front will be moving though the Rockies and Intermountain West on Monday and bring the chance for moderate snow accumulations and gusty winds in areas of terrain. Cooler air will follow behind the front with highs in the 30s and 20s. The front will then bring some rain and snow chances to the central U.S. on Tuesday. 

Cold air will start to seep into the northern Plains by the middle of the week as another cold front begins its march southward.
