What has changed

No significant changes.

Key messages

1) High pressure and a somewhat cooler airmass will be found through Saturday.

2) A series of upper level disturbances will result in occasional rain chances through the first half of next week.

Discussion

KEY MESSAGE 1) High clouds will thicken over the region before daybreak Saturday, which will keep highs generally between 65 to 70 degrees.

KEY MESSAGE 2) A mid level short wave will move out of the mid Mississippi Valley Saturday night and across the Ohio Valley Sunday into Sunday night. There remains some uncertainty as to how much moisture will be pulled up into our area ahead of this, with the NAM and GFS trending towards the drier European and Canadian models which have been precip-free for the last several runs.

A deeper mid/upper level trough is forecast to progress east across the central CONUS early next week, but there remains significant differences in the timing of this as well as the timing/placement/ strength of any embedded short waves. As a result, a fair bit of uncertainty continues with the forecast through the second half of the long term period so will still broad brush with chance pops.

Aviation

VFR conditions will be found over the region with high clouds spreading eastward tonight, then lowering and thickening before daybreak. Northeast wind will maintain a 6-7kt overnight, light and variable at KLUK, and then become more easterly tomorrow as they increase to 10-12kt.

OUTLOOK: MVFR cigs and vsbys possible Sun into Mon.
