UPDATE

Issued at 747 AM EDT WED APR 8 2026

Hourly temperatures and dewpoints were fine tuned based on recent observations and trends. This led to no substantial changes at this time. Temperatures have bottomed out or nearly have bottomed out at this point and frost or freezing temperatures should not be a threat after 10 AM EDT. Otherwise, the rather dry airmass will moderate today and low min humidity is anticipated. A few of the normally colder locations may experience a bit of frost tonight as well.

LONG TERM

(Thursday night through Tuesday) Issued at 355 AM EDT WED APR 8 2026

By Thursday evening, an area of low pressure will have progressed into Quebec Meanwhile, at the start of the long term period on Thursday night, the systems cold front will trail it through the Great Lakes to Middle Mississippi Valley to Central Plains.

Eastern Kentucky will remain south and east of this cold front through Thursday night and Friday. The Southeast US into the Mid- Atlantic, including Eastern Kentucky, will remain under the influence of sfc high pressure and upper ridging. This will lead to clear or mostly clear skies, weak southerly winds, and dry air Thursday night. A healthy ridge-valley split in eastern hollows and valley is anticipated, with valleys dropping into the upper 30s, while ridge tops remain in the upper 40s to low 50s.

This cold front looks to slow down and perhaps stall out in the Ohio Valley vicinity, northwest of the area through Friday, leading to mostly sunny skies, dry weather, light southwesterly winds, and temperatures in the mid 70s to around 80. Friday night the cold front in the Ohio Valley sags south but weakens as it does so. It may lead to isolated shower activity, most likely north of the Mountain Parkway, but will not be significant or meaningful in terms of rainfall.

Saturday, this front stalls out again, currently modeled to stall over the area. To the north, behind the front, temperatures are slightly cooler in the upper 60s to low 70s, while upper 70s to around 80 degrees highs are anticipated ahead of the front, further south. Aside from a mix of sun and clouds, Saturday remains fairly quiet, with the possibility of isolated showers or perhaps a storm or two. Again, this not appear to be significant or meaningful in terms of rainfall either.

A ridge of high pressure building in the Southeast US will result in the boundary lifting back to the north to end the weekend on Sunday, with southerly winds, mostly clear skies, and temperates warming into the 80s. The record high at Jackson of 83 degrees from 2014 may be in jeopardy of being broken on Sunday. Nighttime lows continue to moderate as well, with lows Sunday night mainly in the 50s to low 60s. The next chance of rainfall arrives on Tuesday, but confidence is low, given the strength of the ridge to our southeast, and the continued overall drier pattern in place.

The combination of warming, with continued low humidity and rain- free conditions, will result in a return of increased fire danger concerns to end the week.

AVIATION

(For the 12Z TAFS through 12Z Thursday morning) ISSUED AT 740 AM EDT WED APR 8 2026

VFR conditions will hold through the period as just a few mid and high clouds pass from time to time as sfc and upper level ridging dominate. Northeast to east winds at 5KT or less or light and variable winds will veer or become southeast to south through 18Z remaining at around 5KT and then remain southeast to south at around 5KT through the end of the period.
