Strong Storm Impacting Southern Alaska
Unsettled weather continues for the Pacific Northwest into the northern Rockies. Rain across the eastern Gulf states expected to move off the southeast U.S. coast Thursday afternoon. Showers resume along the Gulf Coast on Friday and then expand toward the southeast U.S. Friday evening.
Forecast for Tuesday, January 28, 2020
An active Pacific jet stream will continue to keep unsettled weather in
the forecast for the Pacific Northwest through Friday. The most recent
batch of moisture associated with a frontal system is expected to spread
eastward across the Intermountain West tonight, and then across the
northern Rockies and northern High Plains on Thursday in the form light
snow for the mountains and areas of mixed precipitation for the lower
elevations. By Thursday night into Friday, the next wave of moisture
ahead of another frontal system is expected to overspread the Pacific
Northwest once again with moderate to heavy snow over the northern
Cascades, while moderate to heavy rain is expected for the lower
elevations down to the immediate coasts. Meanwhile, scattered light snow
and mixed precipitation is expected to move into the upper Midwest.
Further south, a low pressure system centered near the eastern Gulf Coast is forecast to bring rain across much of the southeastern U.S including Florida through tonight. This system is expected to move relatively quickly eastward out into the Atlantic, ending much of the rain across the Southeast by Thursday afternoon. Temperature-wise, milder than normal conditions are expected to continue across the Northern Tier in contrast with cooler than normal conditions for the Deep South under a split flow pattern. As the aforementioned low pressure system departs, the southern jet stream will act to develop another low pressure wave along a front near the Gulf Coast. Rain showers will quickly resume along the western Gulf Coast Thursday night, which will quickly expand eastward through the rest of the Deep South and into the Southeast on Friday, leading to wet, dreary, and cool conditions region-wide. In addition, showers and some thunderstorms are possible over the southern High Plains on Thursday.
