Overview
|
On the morning and afternoon of February 15th A digging upper trough over the east slopes of the Rockies spawned a strengthening surface low over the Southern Plains. Over time this low lifted northeast across the eastern Great Lakes from Saturday the 15th into Sunday afternoon of the 16th. As the center of low pressure propagated eastward, a lead shortwave and an associated plume of Pacific and Gulf moisture overran retreating cold air over PA, which provided ample moisture to spread snow across much of the forecast area by midday Saturday. The initial period of snow was followed by a transition to mixed precipitation during Saturday afternoon and evening. During this transition period, freezing rain and sleet fell on top of already present snow, and the combination of snow/sleet/ice made for hazardous travel conditions across all of central Pennsylvania. An eventual change to rain occurred Saturday night as the warm front lifted north into Pennsylvania, bringing the area into the warm sector under a southerly flow regime. On the backside of this system, a tight isallobaric couplet brought an additional hazard of non-thunderstorm wind gusts which warranted a high wind warning in anticipation of gusts greater than 58 mph. In total central Pennsylvania saw snow amounts between 0.5 inches across the east to near 6.0 inches in the Laurel highlands, ice amounts of between 0.01 inch to 0.40 inch across the area, and wind gusts reaching as high as 64 mph. |
