Marine Weather and Tide Forecast for Boston, KY

DISCUSSION
Issued at 332 AM EST Sun Nov 8 2026

Now - Sunday Night...

Looking across the region this morning, temperatures have fallen down into the low to mid 30s for most places, thanks in part to the surface high pressure, calm winds, and good radiational cooling.
Temperatures in the upper 20s to low 30s are still forecast, with the area-wide Freeze Warning in effect through 10 AM EST. Urban areas will still have the biggest difficulty falling below freezing, however frost development is still likely for those locations. River valley fog has also developed over the past few hours, but should dissipate shortly after sunrise. SInce many of these locations could be experiencing below freezing temperatures, if you are driving through dense fog, pay attention for any slick spots that may form on roadways.

The dry northwesterly flow aloft and surface high pressure will keep us dry to close out the weekend. While it will be chilly this morning, temperatures Sunday afternoon will be slightly warmer than Saturday, with highs in the upper 50s/low 60s forecast. Clear skies Sunday night will again allow for decent radiational cooling to take place. Temperatures will not be as cold as this morning, with the most recent NBM having less than 10% chances for below freezing temperatures Monday morning. Lows will be in the low to mid 30s, so we may end up needing to have one more Frost Advisory before the end of the growing season. River valley fog will also be likely Sunday night, with similar conditions to this morning.

Monday - Wednesday...

Surface high pressure, paired with dry northwesterly flow aloft due to the upper-level ridge over the central CONUS, will keep us in a dry pattern going into the middle portions of the upcoming workweek.
A weaker shortwave over the Red River Valley will shift eastward towards the Tennessee Valley by late Tuesday, but limited moisture with this wave will likely result in no rainfall occurring while it passes by. Surface winds will be generally light, allowing for moderating temperatures. Highs on Monday will be in the low 60s, increasing to the mid to upper 60s Tuesday and Wednesday. Morning lows will be in the upper 30s to low 40s, with the potential for patchy frost in some of the east central Kentucky valleys. By midweek, the upper-level pattern overhead briefly shifts from a northwesterly flow regime to more of a zonal flow pattern before a considerable pattern change takes shape over the latter portions of the workweek.

Wednesday Night - Saturday...

The late week pattern over the Ohio Valley becomes more active as a shortwave over the eastern Rockies/Great Plains swings eastward. As this is ongoing, the polar and subtropical jets will begin to interact and phase with each other, resulting in fairly quick cyclogenesis. This will produce a rather strong system over our area that will move towards the northeast CONUS by the end of next week as a mature cyclone. The timing and progression of the shortwave, as well as the phasing of the jets, will play a role in how much precipitation we get out of this system late Wednesday through Friday. Many LREF members from the most recent run keep accumulations below an inch, with a few members outputting 1-1.5" of precip. With decent cold air being funneled in behind the system, if there is enough post-frontal moisture in place over us, we could see some snow flakes late Thursday into Friday. There are a few isolated members from the most recent LREF outputting light snow, so we will have to see how this system trends over the coming days.

As was previously mentioned, the cold air filling in behind the low will setup a late week/early weekend cool down across the Ohio Valley. Highs Thursday through Saturday will be in the upper 40s/low 50s, with a return to below freezing temperatures for most places Friday and Saturday morning. Conditions will also be dry by the start of the weekend once the system fully departs off to the northeast.

AVIATION /12Z TAFS THROUGH 18Z MONDAY/
Issued at 626 AM EST Sun Nov 8 2026

Patchy fog has developed near HNB and BWG this morning, with fog having cleared from BWG. We expect fog near HNB to dissipate within the next 1-2 hours. Once the fog does clear, VFR conditions are expected to prevail across all terminals through the rest of the TAF period. Winds will be generally light and out of the south and southwest, peaking at around 5-8 kt during the afternoon hours Sunday.
