Marine Weather and Tide Forecast for Jonesville, VA

DISCUSSION
Issued at 1214 AM EST Sat Nov 7 2026

A surface cold front is located across KY, along a dewpoint gradient and near the back edge of overcast clouds. No precip is observed with the front and the upper trough. The presence of clouds ahead of this front should prevent fog development. Clouds will persist through the early morning, then clear out in the mid to late morning once the front moves east and drier air builds in. High temperatures will be cooler today, in the upper 50s to lower 60s in most spots.

Broad troughing along the East Coast will continue through the weekend, then the pattern aloft becomes more zonal for Monday. This will maintain dry weather with a slight warming trend for the first half of next week. A split flow develops, with a southern stream trough ejecting out of northern Mexico and Texas. This will likely just bring some cloud cover to our area on Tuesday, as moisture appears limited.

A pattern shift comes during the second half of next week, and the models have been consistent with this shift for the past several runs. A deep upper trough drops out of central Canada and evolves into a closed low over the Great Lakes, with the northern jet stream dropping into the Deep South. Several spokes of energy rotate around this closed low, which may bring multiple reinforcing shots of cold air from Canada from Thursday through next weekend, along with precip chances. We could be looking at temperatures well below normal late next week, and potentially the first meaningful snowfall of the season for some spots in the southern Appalachians. This will bear watching over the next several days.
