New NEAR TERM, SHORT TERM

NEAR TERM
(Tonight)
Issued at 150 PM CST Mon Dec 4 2023

A narrow ridge of high pressure over the OH into the lower MS valley will shift southeast tonight, lowering wind speeds quickly early this evening. Patchy fog may develop late tonight due to the calm or light flow, clear sky and good radiational cooling. Lows should dip into the lower to middle 30s.

SHORT TERM
(Tuesday through Thursday)
Issued at 150 PM CST Mon Dec 4 2023

The next shortwave will drop southeast from the northern Plains and into the lower MO and OH valleys Tuesday. This will bring surface lows into OH and KY, with a prefrontal trough into north AL and southern TN during the midday to early afternoon.
Temperatures should reach the middle to upper 50s for highs before a cold front arrives early Tuesday evening. A few light showers may clip our far northeast forecast area in Franklin County TN with the frontal passage during the early evening. Strong cold air advection will bring temperatures back into the middle to upper 30s Tuesday night with gusty northwest winds of 15-25 mph.
Temperatures will only rise into the lower to middle 40s in southern TN and the higher elevations of northeast AL. A few spots may squeak by with 50-51 in northwest AL. Morning lows by Thursday morning are forecast to be in the upper 20s to around 30 as another transient ridge of high pressure shifts southeast through the lower MS and TN valleys. As this surface high moves southeast into GA, south-southwest flow will redevelop on Thursday as a mid-upper level ridge axis also migrates east from the southern and central Plains.

LONG TERM
(Thursday night through Sunday)
Issued at 323 AM CST Mon Dec 4 2023

A pronounced mid/upper ridge will then quickly amplify and build east into the Tennessee Valley Thursday and Friday, resulting in a pronounced warm-up late this week. With ample sunshine and winds veering to the southwest daytime highs will return to the 60s. Out next chance for rain -- likely in the form of medium to high (50-80%) chances for showers and thunderstorms which are progged to occur this weekend. The main window appears to be roughly a late Saturday into Sunday timeframe as a very strong upper trough digs into the Mid South and ejects into the Mid South and lower Ohio Valley. At the very least, this system looks as if it will bring some beneficial rainfall as roughly 50-60% of grand ensemble members are indicating 1"+ of rainfall already 6-7 days out. Given the strong dynamics with this system, we will also continue to monitor the potential for thunderstorms and especially any organized convection. Still some spread with the timing and evolution of this system and we will continue to monitor this over the coming week ahead.

AVIATION
(18Z TAFS)
Issued at 1047 AM CST Mon Dec 4 2023

VFR flight weather conditions are expected. There is a low chance of lower clouds (020-030agl) that could drop southeast tonight, but have left out of the TAFs given very low confidence. Westerly winds will gust over 20kt at times through 23Z before diminishing.
