A warming trend occurs through Saturday with dry conditions in place. On Sunday, a cooler airmass arrives to the region and temperatures will be below average through much of the work week. && .NEAR TERM /THROUGH FRIDAY/... High pressure builds in from the north later today and into the overnight hours. Northerly flow and widespread cloud cover keeps temperatures limited to the upper 70s and low 80s today. Toward the late afternoon and evening, clouds should start the scatter and lift a bit with the high building south. Forecast lows drop into the lower to middle 60s tonight under partially clearing skies and calm winds. && .SHORT TERM /FRIDAY NIGHT/... High pressure moves across the Ohio Valley on Friday through Friday night. Much more sun is expected than the past few days. The forecast highs reflect the additional sunshine and weak winds with temperatures reaching the middle 80s by the afternoon. Temperatures drop off after sunset and fall into the lower to middle 60s Friday night under partly cloudy skies. && .LONG TERM /SATURDAY THROUGH THURSDAY/... Mid/upper level low will move across Ontario and the northern Great Lakes through the weekend. This will help carve out a broader trough across much of the eastern CONUS through the middle part of next week. A cold front will drop down through the Ohio Valley Saturday night into Sunday, ushering in a much cooler airmass as we head into next week. Ahead of this, highs on Sunday will be in the 80s but as cooler air begins to move in, highs on Sunday will range from the mid 70s northwest to the mid 80s southeast. High temperatures then through the remainder of the long term period will only be in the 70s. Pcpn chances will remain fairly low with a chance for a few showers with the cold front Saturday afternoon into Sunday and again possibly Monday into Tuesday as the upper level trough axis pivots across the region. && .AVIATION /23Z THURSDAY THROUGH TUESDAY/... Overcast MVFR cigs will occasionally rise to VFR through about midnight. Some breaks in the cloud cover and notably higher VFR conditions are working in from the east and already at CMH/LCK and poised to reach ILN in the next few hours. Models are persistent in showing a break in cloud cover from about 07Z-11Z but I expect a persistence forecast is in order with exception of KILN where 5sm br is noted with scattering cu before daybreak. Cigs should be bkn-ovc tomorrow and just above that MVFR/VFR threshold. Light n/nne winds under 6kt will prevail. Cigs should break up in the early evening as diurnal heating ceases to create the overturning in the higher humidity air at 3-5kft OUTLOOK...No significant weather is expected. && .ILN WATCHES/WARNINGS/ADVISORIES...
