sweetapricity/bridgedeck-noaa huggingface dataset:
Low pressure tracked through the Ohio Valley. Warmer air aloft overran colder air in place that was associated with high pressure over New England, resulting in freezing rain. Ice accumulations ranged from less than a tenth of an inch along and east of Interstate 95, to around one to two tenths of an inch west of Interstate 95, to around a quarter inch in the higher elevations of the Blue Ridge Mountains.

Cold, Canadian air spilled south into the Southern Plains and Lower Mississippi Valley during January 9th and 10th, ahead of strong high pressure over the Central Plains. Meanwhile, an upper trough traversed the Southern Rockies on the 9th and amplified upon entering the Southern Plains during the early morning hours of the 10th, producing a large swath of heavy snow across much of Western and Central Texas, which eventually moved into East Texas and North Louisiana during the afternoon and evening hours. While the heavier snowfall amounts remained south of McCurtain County Oklahoma, some areas of light snow did fall over the southern portion of the county during the overnight hours, as the center of the trough moved through. As a result, the community of Haworth received 0.5 inches of snow.

Low pressure tracking out of the Ohio Valley weakened as it moved slowly eastward on January 31st. Meanwhile, as that low weakened, secondary low pressure began to develop off the coast of the Carolinas and tracked northward, just off the mid-Atlantic coast. The low steadily intensified as it moved up the coast in a classic ���Miller B��� storm evolution. Overrunning precipitation associated with the initial low over the Ohio Valley impacted the region on the 31st. A cold antecedent air mass allowed most of this precipitation to fall as snow over the Delmarva peninsula. This produced widespread snow accumulation, though the overrunning precipitation was mostly of the light to moderate variety. The Delmarva experienced a lull in precipitation on the overnight of the 31st as the secondary low began to develop and a dry slot overspread a large area. In addition, a surge of warmer air both at the surface and aloft caused precipitation to change to sleet or rain. As the secondary low strengthened, precipitation eventually turned back to snow as colder air was drawn in from the north. The secondary low pressure came to a near stall off the mid-Atlantic coast, causing snow to continue into February 2. However, snowfall rates by then were much lighter, and marginal surface temperatures prevented much if any accumulation following the initial batch of snow on January 31.
