Snow showers, some of which were locally heavy at times, reduced visibilities to less than one half of a mile at times in Chester, Delaware and lower Bucks Counties during the second half of the afternoon and evening on the 11th. Localized snowfall reached 1 to 2 inches. This snow was in addition to the snow that fell earlier on the 11th.  The reduced visibilities combined with temperatures that fell below freezing caused several traffic accidents.  Representative snowfall included 1.9 inches in West Chester (Chester County), 1.5 inches in East Nantmeal (Chester County) and 1.4 inches in Wayne (Delaware County).  The snow showers were concentrated along an inverted trough of low pressure which extended westward from a surface low pressure system over the western Atlantic Ocean. An upper air disturbance passing aloft over the area helped to destabilize the air mass and helped manufacture the heavier snow showers.

Light winds and abundant low-level moisture led to the development of dense fog with visibilities of 1/4 mile or less over portions of Southeast Wisconsin east of a line from Ripon to Beaver Dam to Lake Mills, to Janesville.  The dense fog developed during the late evening hours of February 15th and lasted until the early overnight hours of the 16th. Weak low-level warm air advection strengthened an inversion that trapped the low-level moisture.

Strong west to northwest winds occurred over the higher terrain of the Poconos during the early morning of the 18th after a cold front moved through the region. Peak wind gusts averaged 45 to 50 mph and included 48 mph at Mount Pocono (Monroe County). The strong winds knocked down weak tree limbs and wires. The strong winds were caused by the pressure difference between a strengthening low pressure system moving up the Saint Lawrence River Valley and a high pressure system over the Mississippi Valley. Once the low pressure system stopped intensifying, the strong winds ceased.

A few strong thunderstorms impacted the southeast Florida Big Bend.  A cold front stretched from Macon to Bainbridge to Panama City.  Dewpoints were in the upper 60s ahead of the front across south central Georgia and the Florida Big Bend, with lower 60s to the west of the boundary. A deep upper low was located across western Kentucky and moved southeast during the day today, bringing some stronger mid-level flow into the forecast area. This stronger flow aided in increasing deep-layer shear to the 40-50 knot range by the early afternoon across the eastern half of the area. Combined with an unstable atmosphere (SBCAPE around 2000 j/kg from the 12Z TAE sounding), isolated strong storms developed ahead of the frontal boundary.

Over the course of the late night hours on the 30th an upper level trough of low pressure situated over the Arizona and California state line moved eastward towards the Oklahoma Panhandle. Ahead of this trough, a 150mph-160mph jet stream coupled with a surface low pressure system diving southeastward out of southern Colorado initiated precipitation across the Southern Plains. As the surface low continued its southeasterly track, the associated cold front dropped temperatures below the freezing mark. At this time any precipitation falling transitioned quickly from rain to sleet to all snow. Snowfall continued for several hours as moisture wrapped around the surface low before ending from west to east at noon. The highest snowfall amount of 8 inches was observed in the western Oklahoma Panhandle. The snow pack created some icy spots on roadways as reported by local law enforcement. Below is a listing of snow amounts by county:
Cimarron County: 2 W Wheeless 8.0  inches; Felt 7.5 inches; Boise City 6.0 inches; 2 ESE Boise City 5.0 inches.
