.NEAR TERM... (Today) Issued at 133 AM CDT Thu Oct 2 2025
Not as concerned about fog this morning, however cannot rule out some patchy fog in the usual spots. With Imelda well off into the Atlantic, the ridge of high pressure that has been anchored in place the past few days up in the Great Lakes down to the MS Valley, will be able to slide eastward. This will allow for it to be better established across the Southeast today. The building heights and plentiful amount of sunshine will give way to daytime highs above seasonal norms, ranging from the low 80s (NE AL) to upper 80s (elsewhere). For reference the normal high for the start of October is 81 degrees at KHSV and KMSL. The pressure gradient increase will get east/northeasterly winds to 5-10kts with gusts up to 15kts.

.SHORT TERM... (Thursday night through Saturday) Issued at 856 PM CDT Wed Oct 1 2025
The above noted surface high should take up residence off of the New England coast as well go through the latter portion of this week. An E-SE flow should continue over much of the SE CONUS as we go into the upcoming weekend. This should result in daily high temperatures ranging from the upper 70s to mid 80s. Low temps will be noticeably cooler ranging in the 50s (lower 50s east, with mid/upper 50s west). Dry weather should continue for the remainder of the week. Sufficient moisture necessary to bring rain chances to the area should remain to our south given a mean E-SE lower level flow. Thus the dry spell and more noticeable drought conditions will continue.

.LONG TERM... (Saturday night through Wednesday) Issued at 856 PM CDT Wed Oct 1 2025
Our prolonged period of high pressure influenced weather will gradually come to an end through the long term forecast. At the start of the period high pressure at the surface and aloft will be situated off the Atlantic coast. This will induce ESE flow bringing Gulf Stream moisture from the Atlantic to the TN Valley. Locally this will result in a gradual increase in dew points back to the mid 60s through the start of the work week. Unfortunately with temperatures remaining in the mid 80s this will mean slightly more humid conditions than we have been having. The increased moisture will also amount to low rain and storm chances in the afternoon through the middle of the week. As we enter the end of the long term forecast uncertainty increases due to an approaching cold front. It is uncertain at this time if and when the front may move through our area. Changes to the timing and location of the front will impact our rain and storm chances through the end of the week. While we currently retain low rain chances through Wednesday, should the front be strong enough to move south through the area, rain chances will likely increase for mid week.

.AVIATION... (12Z TAFS) Issued at 627 AM CDT Thu Oct 2 2025
VFR conditions will prevail at KHSV and KMSL through the TAF period. Easterly winds will quickly pick up after sunrise and become ~10kts with gusts up to 15kts. Winds will weaken with sunset but remain elevated overnight.
