NEAR TERM /UNTIL 7 AM THIS MORNING/
Amplified mid level flow with a low centered over the eastern Great Lakes and southeast Canada and a ridge over the Rockies.
This places the Ohio Valley in a northwest flow pattern. Surface high pressure centered over the Mid MS Valley to build into the Ohio Valley overnight.

Scattered to broken cumulus clouds continue to dissipate this evening yielding mostly clear skies. Winds will taper off this evening and become light overnight. This setup will allow for good radiational cooling scenario to develop.

Have continued previous forecast thinking - trending a little cooler than guidance in this dry airmass. Expect overnight lows mostly in the upper 30s to lower 40s, but a few cooler readings will be possible in outlying areas across the north and east - where lows in the mid 30s are forecast. Have continued to include some patchy frost wording in the colder locations and issued a special weather statement for this potential.

Record low temps may also be within reach at the Big 3 climate locations (CMH 39 in 1951, DAY 42 in 1898 and CVG 44 in 1956).

SHORT TERM /7 AM THIS MORNING THROUGH 6 PM MONDAY/
The surface high will shift east across the region Sunday into Sunday night. This will lead to continued dry and cool conditions. Highs on Sunday will be in the upper 60s to lower 70s with lows Sunday night in the 40s.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
A large area of high pressure settling slowly across the CONUS is forecast to dictate weather conditions through the period.
Dry weather is expected in the subsident circulation around the high. Increasing humidity on Friday may allow isolated showers, but the chance is below the threshold to show up in the forecast at this time.

High temperatures starting around 80 on Monday will exhibit a warming trend, reaching around 90 Wednesday and Thursday. A slight retreat to the mid and upper 80s is forecast for Friday and Saturday.

AVIATION /06Z SUNDAY THROUGH THURSDAY/
Surface high pressure will continue to build southeast into the Ohio Valley today. A FEW-SCT high clouds may pass by to the north, otherwise mainly clear elsewhere. Light northwest to north winds will become more northwest during the afternoon around 5 knots.

For tonight, the surface high will settle west to east across the Ohio Valley. In the northwest flow aloft, a FEW-SCT mid or high clouds will pass by near the northern terminals. Winds along the Ohio River Valley will go calm while along and north of I-70, winds will back to the south/southwest around 5 knots.
