DISCUSSION
KEY MESSAGE 1) West-east low level jet near/north of I-70 will weaken heading into the morning. this axis will remain favorable for some showers to develop, although any rainfall will be quite light as low levels remain dry.
Short wave emerging from the central Rockies will track east in the base of a broad long wave trough and push across the region late tonight. Ahead of this, there will be some mid level frontogenesis that could lead to another increase in showers north of I-70 during the afternoon. Additional showers extending southwest along a weak cold front will move through the area tonight, possibly not clearing central Ohio until early Saturday morning. Cannot rule out a rumble of thunder, but instability is very limited.
Next cold front will lay out as initial short wave pivots across the upper Great Lakes Saturday afternoon and evening while a second weaker disturbance tracks further south late Saturday night into Sunday. Forcing does not look overly impressive but this will bring another chance of showers, with perhaps a bit of an uptick in coverage as some weak instability develops along it by the time it is exiting the forecast area.
KEY MESSAGE 2) Temperatures will be warming early in the period with readings getting close to normal tonight into Saturday night. But then below normal temperatures will return into mid week with a mean long wave trough over eastern North America.
AVIATION /06Z FRIDAY THROUGH TUESDAY/
VFR will continue with mid clouds moving across the region through much of the period. Cannot rule out a rain shower or two affecting KDAY to KCMH/KLCK early in the period, the better chance of rain will come after 21Z, with that chance increasing through the end of the period. It is possible that may lead to some MVFR conditions at KDAY late. Once again, winds will increase after 12Z with some gusts at or above 20 kt during the day. Winds will decrease and back to the south after 00Z.
OUTLOOK...MVFR ceilings and visibilities possible late tonight into Saturday morning.
