Storm Summary:

A complex weather situation took shape across the Central Plains between Saturday, March 9, 2013, and Sunday the 10th. Initially on the afternoon of March 9th, a narrow line of strong thunderstorms developed along a passing cold front, some containing small hail, which affected many areas near and east of Highway 281. Nickel size hail was reported six miles north of Esbon, KS. In addition to small hail, some of these storms contained locally heavy rainfall, with the 1.17" of precipitation recorded at Hastings Municipal Airport setting a daily record for March 9th (precipitation records for Hastings, NE date back to 1895).

In the wake of the very strong cold front, narrow bands of moderate to heavy snow then developed across portions of the NWS Hastings coverage area, mainly during the very early morning hours of March 10th, with some areas seeing snow last well into the daytime hours Sunday. Due to the very fickle nature of these narrow bands, snowfall totals varied considerably across the local area (see the visible satellite image below). By Sunday evening, the highest snowfall totals were noted mainly east of a line from Aurora to Hastings, NE to Smith Center, KS, where a fairly widespread band of 3" to 7" of snowfall accumulated, with locally higher amounts embedded.

Where appreciable snow fell, Saturday night and Sunday, the visibility was one-half mile or less for most of the daylight hours Sunday. In fact, the visibility was frequently much lower. This storm was officially classified a blizzard, at Hastings and York, where visibility sensors are available. However, blizzard conditions occurred, for virtually all areas, where snowfall accumulated. There are three specific criteria for a storm to be classified a blizzard (and they have nothing to do with how much snow fell):

Winds sustained, or frequently gusting, 35 mph or higher
Visibility one-quarter mile or less, in falling and/or blowing snow
Both of the above criteria must occur for a minimum of 3 non-consecutive hours

The official snowfall for Hastings on March 10th was 5.3 inches, which set a new calendar day snowfall record. The previous record was 5.0 inches set in 1907. In Grand Island, the daily snowfall record for March 10th was tied at 3.5 inches. This record was previously set in 1962.

The snow, heavy at times, was accompanied by intense north winds of 25 to 35 mph, gusting to over 50 mph at times. Hastings, NE reported the highest wind gust at 54 mph across the local area, with a list of some of the more notable wind gusts displayed in the table below.
