Weather across America

Published: 04/04/2022, 12:41 AM

(NATIONAL) Increasingly stormy conditions expected to impact the Pacific Northwest to the northern High Plains, heavy rain and severe thunderstorm threat expands across the Deep South, and a Critical Fire Weather Risk over the Northern/Central Plains.

A potent low pressure system will bring increasingly active weather into the western U.S. towards the Plains over the next couple of days.  In the meantime, a compact low pressure is forecast to intensify as it slides relatively quickly off the New England coast later Sunday night. 

Some bands of rain/snow are expected to rotate through New England Sunday night. The relatively fast motion of this system will limit the snowfall amounts. Nevertheless, some locally enhanced amounts of wet snow are possible particularly over the higher elevations of upstate New York into interior New England. 

Another fast-moving surface wave is forecast to spread light amounts of rain/snow across the Upper Midwest and Northern Plains Sunday night through Monday.

Farther south, a thunderstorm threat will be suppressed into southern Florida for the next couple of days as a cold front becomes nearly stationary. Moisture from the Gulf of Mexico will begin to turn north toward the southern tier states and converge with a cold front slowly moving through the Central Plains. This will lead to a steady expansion of showers and thunderstorms from the Southern Plains into the Deep South over the next couple of days. 

The rain and storms are expected to intensify as they reach into the Deep South later Monday into Tuesday with the possibility of flash flooding and severe weather. Showers and thunderstorms spread into the Midwest and Mid-Atlantic by Tuesday night.

Meanwhile, a potent low pressure system is forecast to bring increasingly stormy weather across the Pacific Northwest through the Northern Plains over the next couple of days. This system will dump heavy snow along the Cascades before expanding into the Northern Rockies together with high winds. 

Near the Pacific Northwest coast, moderate to heavy rain and scattered thunderstorms will be accompanied by strong and gusty winds, especially on Monday. Heavy snow will be measured in feet over the northern Cascades.  By Monday night into Tuesday morning, the low pressure system is forecast to impact the Northern Plains/Rockies with high winds as rain/snow moves through the region.
