Marine Weather and Tide Forecast for McMinnville, TN

SHORT TERM
(Rest of today through Wednesday)
Issued at 1034 AM CST Tue Jan 14 2025

Started off the day with some down right frigid temperatures! Crossville got down to 14 degrees and Nashville got down to 19 degrees. Thankfully, ample sunshine today will help warm temperatures into the upper 30s along the Plateau and mid 40s elsewhere this afternoon. Clouds will increase tonight ahead of yet another cold front that will work through the area overnight into Wednesday. A few flurries may be able to squeeze out across our northeastern counties, but otherwise, this will be a mostly dry frontal passage.

This surge of cold air will keep Wednesday's highs mostly limited to the 30s, except for the southwest where a few low 40s will be possible.

LONG TERM
(Wednesday Night through next Tuesday)
Issued at 1034 AM CST Tue Jan 14 2025

The cold will continue until Thursday when we'll finally see a brief boost in our temperatures. An upper-level trough will begin working through the area with our winds turning back out the south by Friday. This will set the stage for our next rain chance as return flow brings moisture and warmth back across middle TN. Rain chances will gradually increase through the day Friday with rain likely Friday afternoon into Saturday. NBM maintains an 80% chance of rain during this timeframe. Light snow showers on the back side of the exiting low still remain possible Sunday, mainly over the Plateau.
Still not looking like much of anything in the way of accumulation as drier air will be settling in from aloft. If enough moisture is available, maybe a tenth of an inch or so could squeeze out, perhaps a bit more if northwesterly flow kicks in over the higher elevations. Temperatures will majorly cool back off Sunday as the cold front moves through, bringing overnight lows of the teens back.

As we move into next week, models continue to favor another very cold week with ensembles showing temperatures as much as 25 degrees below normal. Both the NBM and the Canadian are picking up on possible wintry precip next Monday, but NBM PoP remains low, around 15%. Right now, the biggest impact will be the cold. The NBM only gives a 10-20% chance of afternoon highs rising above freezing next Monday with overnight lows dipping into the low teens to single digits.

AVIATION
(18Z TAFS)
Issued at 1105 AM CST Tue Jan 14 2025

VFR conditions are expected to prevail through the TAF period at KCKV, KBNA, and KMQY. There is a low probability that cigs drop to MVFR after 03Z at these terminals, however, guidance continues to suggest that MVFR cigs are more likely along and near the Plateau, including KSRB and KCSV through early Wednesday morning.
Otherwise, S/SW winds will become N/NW as a cold front begins to track through the area starting around 21Z.
