Harper evolved from a large low pressure system just of the Pacific Northwest coast. Energy from that system spread high elevation snow to the Sierra and rainfall to much of California on Jan. 16-17.

More than 4 feet of snow was reported in the Sierra Nevada from Harper.

The snow closed Interstate 80 through the Sierra at times as high winds gusted over the mountains and crashes occurred in Donner Pass.

Winds gusted over 130 mph in parts of the northern and central Sierra late Jan. 16 into early Jan. 17. Mammoth Mountain even gusted to 164 mph with a sustained wind of 132 mph early on Jan. 17.

Harper spread some snow through the Rockies and Utah's Wasatch on Jan. 17 while continuing to provide snow in the Sierra and Cascades.

On Jan. 18, numerous slide offs were reported in eastern Nebraska and northwestern Missouri where light freezing rain made roads and sidewalks slick. A Southwest plane slid off the runway in Omaha in snowy and icy conditions.

Light snow was reported in parts of Oklahoma and Texas, including the Dallas area, early Jan. 19.

Freezing rain early Jan. 19 resulted in ice accumulation that downed power lines in parts of central Indiana, including Winchester, Losantville and Farmland.

At least a foot of snow fell Jan. 18-19 in southeastern South Dakota, southern Minnesota and eastern Wisconsin, including a report of 15 inches near Heron Lake, Minnesota.

Several accidents were reported on Interstate 44 in Missouri due to the snowy conditions there Jan. 19. Near-blizzard conditions also created a 15-car pileup in south-central Missouri.

Winter Storm Harper dumped 1 to 2 feet of snow in parts of the Northeast as it rolled up the East Coast Jan. 19-20. The heaviest strip was from east-central New York through central New England and into Maine.

Harper brought 16.9 inches of snow to Caribou, Maine, vaulting the town to its snowiest January on record (46.6 inches).

Warm air punched northward ahead of Harper's surface low on the East Coast, bringing mainly rain to New York City and Cape Cod.

A heavy stripe of freezing rain accumulated from western and central Connecticut into western and central Massachusetts.

Ice accretion of just over three-tenths of an inch was reported in Meriden, Connecticut, early Jan. 20. The ice caused some power outages and tree damage in Hamden.

Up to a quarter inch of ice accretion was recorded in Springfield, Massachusetts.

The warm southerly air also caused some minor coastal flooding in Delaware, New Jersey and Massachusetts early on Jan. 20. Multiple streets were underwater in Scituate, Massachusetts, due to the astronomical high tide and strong winds. A few streets around Boston, including I-93 had some flooding.

Here are selected snowfall and ice totals from Harper Jan. 16-20, 2019. Some totals may include snow from other disturbances, especially on the West Coast. For snow, only totals greater than 4 inches are included.
