NEAR TERM /UNTIL 6 AM SATURDAY MORNING/
CAA cu have developed across portions of the region. In addition, some high clouds are still in place across primarily southern portions of the region. Expect a general decrease in cloud cover for the overnight hours. With cooler airmass in place low temperatures are expected to drop down into the 50s across most locations overnight tonight. There will be the potential for some river valley fog again tonight.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/
High pressure will continue to bring dry conditions to the region Saturday and Saturday night. Slightly warmer conditions will be in place for Saturday and Saturday night with highs in the 80s and lows in the 60s. A few cu and high clouds will still be possible, however less than Friday.

LONG TERM /SUNDAY THROUGH FRIDAY/
A warm, humid, and convectively active weather pattern is setting up for next week.

On Sunday morning, a mid-level ridge axis will be very slowly moving eastward. Relatively dry air, with subsidence, will be exiting the middle Ohio Valley to the east ahead of this ridge axis -- and copious moisture return on deep-layer southerly flow will be occurring on the other side. From late Sunday through Monday, a trough axis will extend from the upper Midwest through the Ohio Valley, focusing a broadly favorable convective environment over a regime with precipitable water values approaching 2 inches. This moist air mass will persist through the week, with surface dewpoints in the 70s from Monday through Friday. Finally, a generally northwesterly flow pattern behind the initial trough will support occasional chances for convection, rather than any kind of ridging or capping. Thus, thunderstorms will be possible at times through the entire extended forecast period.

Precipitation chances on Sunday look greater late in the day into the evening, and mainly in the southwestern half of the forecast area. By Monday, as the trough over the Great Lakes moves eastward, precipitation chances will increase across the entire region. Monday currently has the greatest precipitation chances of any day this week, though part of that is temporal certainty, since Monday is a little more clear than days further out in the forecast. Chances may diminish slightly by Wednesday after the trough axis has passed the area, but a more episodically active northwest flow pattern may then take shape from the plains through the midwest. Confidence in any forecast specifics beyond Wednesday is low.

With moist profiles and uncertainty regarding deep-layer shear, the severe risk remains uncertain at this point. There could be some potential for heavy rainfall and isolated damaging wind on Sunday and Monday, with MCS activity becoming more possible later in the week. Confidence is too low to include in the HWO as of now.

AVIATION /00Z SATURDAY THROUGH WEDNESDAY/
High pressure moving into the region results in mostly clear skies during the overnight hours. As previously mentioned, river valley fog is possible, so continued VSBY reductions at KLUK during the late overnight hours. Winds out of the northeast at 5 knots or less.

Fog dissipates after sunrise. Winds shift to have a more easterly component during Saturday, but remain under 10 knots.
Few to scattered cu linger throughout the day before high clouds begin to spill Saturday evening ahead of the next system, poised to arrive Sunday.

OUTLOOK...Thunderstorms are possible Sunday through Wednesday.
