WHAT HAS CHANGED
No significant changes.
KEY MESSAGES
1) A weak low pressure system will bring scattered light rain showers back into the area late tonight through the daytime Friday.
2) Some frost is possible Friday night and again Saturday night, with impacts to sensitive vegetation likely.
3) Extended period of cooler conditions settles into the region through the weekend, with slowly moderating temperatures into early next week. A seasonably cool pattern with several chances for light rain will evolve through most of the next week.
DISCUSSION
KEY MESSAGE 1)
Another cold front and weak upper level shortwave trough move through the Ohio Valley late tonight into Friday. Isolated to scattered rain showers are expected during this timeframe. Some graupel and lightning are possible during the day on Friday due to weak instability and some mixed phase hydrometeors in the cloud layer. Highs remain below average on Friday on breezy northwesterly flow.
KEY MESSAGE 2)
Frost is possible on Friday night and Saturday night. The best frost potential on Friday night is across areas along and north of I-70 where cloud cover is more likely to scatter out. For Saturday night, frost potential is greater over the entire area due to high pressure building in from the northwest likely creating better conditions for radiational cooling.
KEY MESSAGE 3)
Cool conditions remain in place through the weekend into next week. A wetter synoptic pattern may also develop next week as a series of surface lows and upper level shortwave troughs progress through the region with mean troughing over the Great Lakes.
AVIATION /00Z FRIDAY THROUGH TUESDAY/
Brief ridging will shift east across the middle Ohio Valley through the early stages of the TAF period before a weak cold front brings a short period of precipitation late tonight. Guidance suggests cloud bases could initially drop below 3,000 feet behind the front Friday morning, though this is less certain at the Cincinnati terminals. Winds will pick up out of the northwest with a few 20-knot gusts Friday afternoon.
