KEY MESSAGES

Updated at 103 PM CDT Tue Oct 27 2026

- Medium chances of showers and a few storms will return to the forecast Saturday into Sunday.

NEAR TERM

(Tonight) Issued at 103 PM CDT Tue Oct 27 2026

Tranquil conditions across the region again this afternoon, but clouds will be on the increase later this evening and overnight as a shortwave trough ripples across the Mid South and lower Ohio Valley. Though the area is devoid of moisture at the lower-levels, this will still result in an increase of mid/high clouds overnight, which may help keep temperatures a few degrees higher than last night (lows in the upper 40s to lower 50s). If there are a few breaks in the clouds some very localized patchy fog could develop in sheltered valleys, but given the potential for cloud cover have kept a mention of this out of the forecast for now.

SHORT TERM

(Wednesday through Thursday) Issued at 828 AM CDT Tue Oct 27 2026

The aforementioned shortwave will quickly pass through the region on Wednesday, but other than cloud cover, no impacts are forecast. And, despite these clouds, highs in the 70s will be common again. An area of high pressure over the northern Gulf will amplify on Thursday in wake of the exiting shortwave. This will result in a sunny/warm day, with southerly winds pushing highs close to the 80 degree mark.

LONG TERM

(Thursday night through Monday) Issued at 835 PM CDT Mon Oct 26 2026

The long term period will begin with zonal flow aloft as the TN Valley sits between low pressure off the western Atlantic and an amplifying ridge over the southern Plains. This will ultimately result in tropical air advection ahead of an upper wave progged to move across the central Plains and into the upper Midwest over the weekend, bringing increased moisture and above normal temperatures to the area. There is some indication that a secondary low may form across the Ozarks/mid MS River Valley that would enhance synoptic lift closer to home and would bring increasing rain chances on Halloween. For now we will stick with blended guidance, bringing low to medium (30-50%) chances for rain beginning Halloween afternoon and increasing overnight, and continuing through Sunday. While severe weather does not look to be a threat with this system at this time, low chances for thunderstorms will exist on Sunday.

This system will exit the area late Sunday and high pressure will move into the area by the start of the next work week. This looks to be short lived, as another and potentially more dynamic system sits just beyond the day 7 period and could bring additional rain and thunderstorms to the area early next week. Since this is beyond the 7 day forecast period at this time, we will hold on for better forecast consistency but feel it will bear watching as it may impact Election Day.

AVIATION

(18Z TAFS) Issued at 1134 AM CDT Tue Oct 27 2026

VFR conditions will be the predominant flight category at each terminal through the period with light winds. Mid to high clouds will increase overnight ahead of a weak front that will move through the region tonight into Wednesday. A low chance of patchy fog will exist, but confidence is too low on its occurrence based on the aforementioned clouds, so will keep out of the forecast for now.
