Technical Forecast Discussion
Short term (Sunday 3/3 through Tuesday 3/5)
Upper level troughing slowly digs and brings down colder air as highs are around the mid 30s. With the combination of ascent from being downstream of the trough and the influx of moisture following the flow, conditions for precip development are favorable. A mix of rain and snow is possible for Sunday with models favoring snow as Southeast Ohio looks to be in the northwest sector of the system. Snow accumulation is likely to be around 1 to 3 inches Developing ridging in the Central Plains will create high pressure that moves eastward. By mid-Monday conditions should clear out, but remain cold as the trough remains over the area bringing down colder air from Canada. Ridging will continuing to strengthen as the trough moves off the eastern coast of the U.S. This should prolong clear conditions and possibly bring some WAA as warmer air moves north and trapped moisture could insulate the lower levels.
Long term (Wednesday 3/6 through Saturday 3/9)
Upper level flow continues to level out on Wednesday. This will result in WAA as the the trough to the east lifts. Temperatures look to reach the mid 30s for Wednesday as WAA will begin to take affect early Thursday. A embedded shortwave trough will quickly move through the region Thursday sometime between the late afternoon and the evening. This shortwave feature will allow for moisture to be advected northward as a stream of it exists moving northwest to southeast across the U.S. This will bring moisture over SE Ohio on Thursday and likely bring a period of rain showers as the trough will bring necessary lift. The shortwave will move off to the east and help amplify the trough over the coast as showers dissipate as Friday progresses. Showers are still possible for Saturday as the presence of troughing is visible over the plans which will send a low pressure system into the region later into the day.
