KEY MESSAGES

- Heading into the weekend, temperatures will linger just below normal levels. Readings will eventually trend warmer early next week.

Well we are really doubling down on the cooler air today, as low clouds persist across most of the region. There is a small break over eastern portions of southeast Missouri where temperatures may climb closer to originally forecast high temperatures, but elsewhere, highs are only expected to reach the upper 60s to lower 70s this afternoon. Although guidance has no clue at this point, it is likely that the low clouds will linger into, if not through Wednesday. Therefore, the NBM highs on Tuesday may be a bit on the warm side again.

The upper low over northwest Illinois will drift east southeast and should eventually reach the Ohio Valley by the end of the day Wednesday. Once this happens, clouds should become less prevalent. An upper-level ridge will build over the Quad State Thursday into Friday and that will lead to some beautiful weather to end the work week.

The latest guidance continues to show some potential for energy to quickly suppress the ridge allowing for some chance of showers or thunderstorms over the weekend or into next week. Unfortunately, the overall trend is for this to occur later and confidence in timing is very low. Besides, most upper highs/ridges have tended to linger over our area this summer/fall, so there is a possibility that it could hold firm through the weekend and into next week. The NBM has some 20-30% PoPs overspreading the entire area next Tuesday with virtually dry conditions until then. At some point when the ridge does try to break down, south winds and a warming trend will develop, but the timing of that is also difficult to call at this time. In the meantime, enjoy this fall-like weather!

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/

MVFR ceilings are covering most of the region, with the exception of KCGI, where mixing is holding them off just to the east. With a persistent northeast fetch the low ceilings will likely linger through the period. Figure KCGI will see a return of the ceilings toward 00Z when mixing ceases. A period of IFR ceilings is expected overnight through much of the morning across the northern sites.
