Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 248 AM EST Tue Feb 13 2024 Valid 12Z Tue Feb 13 2024 - 12Z Thu Feb 15 2024 ...Strong nor'easter to impact portions of the northern Mid-Atlantic and southern New England today with areas of heavy snow, strong winds, and coastal flooding... ...New storm system to arrive across the Northwest over the next couple of days which will bring locally heavy rain and mountain snowfall... A strong nor'easter will be rapidly pushing east and away from the Mid-Atlantic coast this morning and well out to sea by later today. The storm will continue to rapidly deepen and will promote areas of snow, or rain changing to snow early this morning across south-central to eastern Pennsylvania, central and northern New Jersey, and southern New England. The axis of heaviest snowfall is expected from eastern Pennsylvania, including the Lehigh Valley, through northern New Jersey, far southeast New York, and southern New England. This will include the greater New York City metropolitan area. Some areas especially over southern New England are expected to see as much as 6 to 12 inches of snow, with lesser amounts of 3 to 6 inches elsewhere, and this heavy snow is expected to produce locally significant travel disruptions. Strong winds are expected on the back side of the departing low center, and this coupled with the heavy, wet snow may result in downed trees and power lines which will result in concerns for power outages. Some coastal flooding will also be possible today during high tide along the northern Mid-Atlantic and southern New England coasts. Meanwhile, there will be a weak storm system crossing the central Plains, Midwest, and Great Lakes region on Wednesday and Thursday. Despite the relative lack of cold air for this system to work with, there will be a swath of locally a few inches of snow, with some rain closer to the track of the low pressure center. A new storm system will also be arriving in from the Pacific Ocean for Wednesday and Thursday which will bring in a new surge of moisture and areas of locally heavy precipitation. This will include heavy rainfall for the coastal ranges of the Pacific Northwest and down into northern California. Locally a couple inches of rain can be expected. Farther inland over the higher terrain of the Cascades, Sierra Nevada, and gradually the northern Rockies, this precipitation will fall as heavy snow. As much as 1 to 2 feet of new snow with isolated heavier amounts can be expected going through Thursday. The remainder of the country going through the middle of the week will be rather dry and tranquil. Temperatures for large areas of the Midwest will continue to be above normal, with temperatures somewhat below normal for the Northeast and Intermountain West. There will be the beginning of a surge of at least modified Arctic air from Canada by late Wednesday and Thursday into the northern High Plains, and this will set the stage for even colder temperatures anomalies arriving by the latter part of the week.
