WHAT HAS CHANGED
Added mention of frost Friday night and Saturday night.
KEY MESSAGES
1) A low pressure system moving through the Upper Ohio Valley will track off to the east taking light rain with it.
2) Extended period of cooler conditions settles in over the region through the rest of the week, continuing into the weekend.
DISCUSSION
KEY MESSAGE 1)
Surface low pressure over the Upper Ohio River Valley to continue pulling away from the region. Rain along and east of the I-71 corridor will move out of the region by late afternoon. Mid level shortwave and surface trof will support the development of some additional showers and perhaps a rumble of thunder late in the day into the evening. This activity will be observed across West Central Ohio into Central Ohio prior to ending late this evening. Cooler temperatures will be observed overnight with lows between 40 and 45.
KEY MESSAGE 2)
A secondary cold front moves thru the area Friday as mid level energy digs southeast amplifying the long wave trof. This system will offer a chance for showers followed by colder temperatures. The coolest temperatures are forecast on Friday night and Saturday night, when frost looks possible. High temperatures on Friday are expected to be between 55 and 60 and in then in the lower and middle 50s Saturday. Low temperatures on both Friday night and Saturday night look to range from the lower 30s to the upper 30s.
Following the surface high pressure this weekend, the next chance for rain is on Monday.
AVIATION /00Z THURSDAY THROUGH MONDAY/
Light showers will quickly decrease in coverage this evening as a low-level trough continues to exit off to the east, so have left out any mention of visibility impacts at this time.
Otherwise, guidance suggests low MVFR ceilings will form late tonight into Thursday morning in the northwest flow off Lake Michigan. Have included these at all terminals except those in the Cincinnati area, since there is uncertainty as to how far south (and west) these clouds make it. Stratocumulus will burn off late morning into early afternoon.
OUTLOOK...Significant weather is not expected.
ILN WATCHES/WARNINGS/ADVISORIES
