Light to moderate snow will continue into Saturday over the Great Lakes, Central Appalachians, and Northeast. This weekend into next week, a series of atmospheric rivers will bring gusty winds, periods of heavy rain, and mountain snow to northern California and the Pacific Northwest. Colder temperatures are in store for the weekend from the Great Lakes to East Coast. Read More >
Overview
A strong coastal storm affected the eastern mid-Atlantic and Northeast US on January 28-29, 2022. As a deep trough moved into the Southeast US, low pressure began to develop off the coast of the Carolinas during the afternoon of January 28. A high amplitude upper level steering pattern caused the developing low to begin moving north-northeastward, paralleling the US East Coast. In a classic Nor’easter evolution, the developing low phased with a frontal system over the mid-Atlantic as it moved north. This frontal system had brought light snow to portions of the mid-Atlantic during the day on the 28th, and it also brought a fresh influx of cold air to the region. As it phased with the developing coastal storm, the coastal storm began to explosively intensify as it passed offshore of Delmarva. The strengthening storm spread precipitation back into the region, which fell as all snow thanks to the fresh injection of Arctic air. With the center of the low passing a few hundred miles offshore, the heaviest snow fell near the coast, from the night of the 28th through the morning of the 29th. In eastern New Jersey and coastal Delaware, several hours of heavy snow resulted in a widespread swath of 12 to 18 inches of snow. Amounts steadily tapered off heading further inland, though some snow fell in all of the local area. In addition, with the rapid strengthening of the low, strong winds also occurred, especially near the coast. Gusts of 40 to 50 mph with a few over 60 mph were observed. The combination of strong winds and heavy snow led to whiteout conditions along the coast, and was sufficient for blizzard criteria to be met along both the New Jersey coast and the Delaware Beaches, making this the first blizzard to affect any portion of the region since 2018. Snow gradually lost intensity and came to an end during the afternoon of the 29th, as the still strengthening low continued moving northward, bringing blizzard conditions and even heavier snow to southeast New England. The combination of the strong area of low pressure and strong winds also brought elevated water levels along the coast. However, water levels were somewhat tempered by prevailing winds during the event being more northerly than easterly. In addition, the highest surge values occurred outside the times of the highest astronomical tides. Because of this, only minor coastal flooding was observed along the Atlantic coast and back bays. The storm also brought significant marine impacts, with a combination of storm force winds, high seas, and freezing spray.

The National Weather Service in Mount Holly, New Jersey can confirm that blizzard criteria was met last night and this morning along the coastal strip of New Jersey and along the Delaware Beaches. This includes areas such as the Monmouth County coast, Long Beach Island, Atlantic City, Cape May, and all of the Delaware Beaches. A blizzard is defined as three or more hours of visibility reductions to one quarter mile or less due to falling or blowing snow, and sustained winds or frequent gusts of 35 mph or greater. Further analysis will be conducted in the days ahead to determine which additional inland zones, if any, reached blizzard criteria during this event. Further analysis will also be conducted to determine the exact start and end times of blizzard conditions in the areas where such conditions have already been confirmed. $$
A few notable graphs of coastal and marine weather impacts are presented below. As is typical for a strong Nor'easter, high winds, coastal flooding, and marine weather impacts were all present during this event.

The buoy is located about 20 miles east of Fenwick Island, DE. | Figure 4: Same as Fig. 4, for NDBC Buoy 44066, located about 80 miles east of Long Beach Island, NJ. | Figure 5: Combined plot of wind speed, gusts, and air pressure at Buoy 44009 during the event. |
Figure 6: Plot of ice accretion values at the Sandy Hook, NJ NOS gauge (SDHN4) during the January 28-20 event. This can be used as a proxy for freezing spray accumulation. The data shows that ice accretion rates near to above 1"/hr occurred for several hours. These are significant and uncommon values for our region. | Figure 7: Same as Fig. 6, for Ship John Shoal (SJSN4) on Delaware Bay. Ice accretion values here were not as large but still quite significant and long duration. |
Figure 8: Tidal hydrograph for Delaware Bay at Lewes (LWSD1) during the January 28-20 event. Water levels at Lewes peaked just slightly beneath the Moderate flooding threshold. | Figure 9: Same as Fig. 8, for Great Egg Harbor Bay at Ocean City (ONCN4. Minor flooding also occurred here. In addition, northwest flow after the storm caused a significant drop in water levels, and the station nearly reached its "low water" crtieria on the night of January 30. |
