Below you will
find an informational weather briefing issued by the National Weather Service in Pittsburgh regarding an upcoming winter weather event.
What: A winter weather advisory has been issued across our entire region for a wintry mix of precipitation that will occur through the day Saturday.
- Up to 2" is expected across southeast OH, far southwest PA, and the northern panhandle of WV.
- 1-3" is expected across the rest of southwest PA and the southeast ridges.
- 3-5" is expected mostly to the north and east of Pittsburgh.
When: Snow will begin across southeast Ohio around 1am Saturday, reaching the rest of the region by 4am Saturday.
Snow will begin shortly after midnight tonight. It will transition to a wintry mix during the morning hours Saturday before turning over to rain through the afternoon and evening hours.
Confidence: High confidence in the development of snow and transitions to wintry mix and rain through the day. Medium confidence on accumulation amounts for each precipitation type.
Best Case Scenario: Warm air is stronger than expected and heats surface quicker, causing a precipitation to change quicker than expected. This will result in low snowfall and ice accumulations.
Worst Case Scenario: Warm air is slower reaching the surface and is slower to warm the region above freezing. This will result in more snow accumulation along the I-80 corridor, potentially reaching warning criteria. Though not warning criteria, more ice accumulation would occur for all locations.
