Overview
| A progressive upper level shortwave trough brought a period of mixed wintry precipitation to central Pennsylvania during the early morning hours on February 6, 2025. Cold air damming east of the Allegheny Front to the south of a retreating 1030mb high pressure system was reinforced by evaporative cooling effects as precipitation expanded into a low dewpoint airmass. However, the air above the boundary layer did warm quickly, with a sharp nose of warm air advection within the 850-650mb layer. Some areas briefly saw snow, but the dominant precipitation types were sleet and freezing rain. Travel conditions were at their worst during the predawn hours and early morning commute. Snow and sleet accumulations ranged from a coating to 1 inch. Ice accretion of 0.20 to 0.40 inch was observed in portions of Cambria and Lancaster Counties. |  Analysis of ice accretion reports on Feb 6, 2025. |

| WPC Surface Analysis valid 09z Feb 6, 2025. | ACARS sounding at Harrisburg International Airport at 1220z Feb 6, 2025. A mix of rain and sleet was observed at the time of the sounding. |
