Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 AM EDT Sat Oct 14 2023 Valid 12Z Sat Oct 14 2023 - 12Z Mon Oct 16 2023 ...A low pressure system will bring unsettled weather from the upper Midwest to the Mid-Atlantic region today... ...Windy but slowly improving weather expected across much of the eastern U.S. on Sunday into Monday as the strong low pressure system moves off the East Coast... ...Dry across much of the western half of the country but rainy along coastal Pacific Northwest and northern California... A low pressure system currently centered over the Midwest will be the main weather maker across the country over the weekend. This system is forecast to slide eastward through the Ohio Valley today before reaching the Mid-Atlantic states this evening. Bands of moderate rain, with locally heavy rain and some embedded thunderstorms, can be expected across the Midwest and lower Great Lakes early this morning but they will quickly spread east into the Mid-Atlantic region today. By Sunday, the low is forecast to move off the Mid-Atlantic coast as it merges with another low pressure wave moving up the coast of the southeastern U.S., The merger will result in a larger and more potent system to rapidly move off the East Coast Sunday morning. The heavy rain associated with the system is not expected to impact land due to its rapid motion but the associated strong winds are expected to affect much of the eastern U.S. on Sunday, which will only subside slowly by Sunday night into Monday. Clouds and some rain will linger farther inland over the lower Great Lakes and Ohio Valley with dry conditions across the Deep South. Meanwhile, mainly dry conditions will prevail across much of the western half of the country for the next couple of days. The exception will be along coastal Pacific Northwest and northern California where rainy conditions will likely continue as a weakening front becomes nearly stationary just offshore. Calm wind and clear skies will result in below freezing temperatures over the central to southern High Plains as well as nearby Rockies in the early morning hours for the next few days, prompting Freeze Warnings/Watches to be issued for this region.
