UPDATE. For 00Z TAFS.

NEAR TERM. (Tonight) Issued at 122 PM CST Tue Nov 30 2021

A weak cold front was situated along the OH River valley to the TX panhandle where a lee side low pressure was developing. A shortwave in mid to upper levels was pushing through NE/KS and will dampen significantly tonight as it arrives in the lower TN valley, but will help to draw the front north as a warm front as a low moves northeast into central MO. The result for our area will be continues south-southwest flow and warm advection. Temperatures tonight will be milder than recent ones with a modest ridge-valley split. Sheltered valleys will have lows in the middle to upper 30s, with upper 30s to lower 40s in the higher elevations above the inversion and also near larger bodies of water.

SHORT TERM. (Wednesday through Thursday) Issued at 122 PM CST Tue Nov 30 2021

Unseasonably mild air will continue the next few days. A secondary shortwave will follow behind the first one on Wednesday producing rather strong positive dPVA and warm advection, with a decent -divQ couplet. The surface, 9h and 8h troughs do not appear to be in phase with the upper wave and arrive Wednesday night. The lower to mid levels will be far too dry for precipitation Wednesday, but a significant amount of mid and high cloud layers should develop/arrive by midday into the afternoon hours. The thermal ridge at 850 mb and deep layer mixing will be sufficient despite the clouds to yield high temperatures in the middle to upper 60s. If the clouds do not materialize, a few 70s can't be ruled out. The lower level and surface trough axis will pass through Wednesday night or early Thursday. We will have to monitor low cloud trends late Wednesday night into Thursday morning ahead of this feature which the NAM is particularly bullish with. For now, will only include partial sky cover as we further assess. NAM soundings even indicate some prospect of patchy drizzle. The clouds should dissipate behind the trough passage Thursday morning as a deeper layer ridge builds just to our west and surface pressures increase over the central Gulf States. There remains some uncertainty on warming as NAM soundings hang onto the lower level inversion longer, while the GFS is much drier and mixes the low levels more thoroughly which looks more favorable. Thus, highs in the upper 60s to lower 70s are forecast at this time.

LONG TERM. (Thursday night through Monday) Issued at 122 PM CST Tue Nov 30 2021

The split flow pattern across the southern U.S. looks to continue playing havoc in the extended forecast, especially for days 6-7 (Sun-Mon). The first shortwave associated with the southern stream jet core will remain quite unphased with the polar jet, thus keeping rain chances low on Saturday into early Sunday. The 12Z runs of the GFS and ECMWF are in better agreement with the associated cold front form the northern stream system pushing through Sunday night with greater rain chances. The GFS is still more significant with rain coverage and amounts, stronger shear but limited instability. thus, will keep rain chances in the chance range with no thunderstorms just yet. This will need to be monitored over the coming days for instability trends and possible addition of thunderstorms.

AVIATION. (For the 00Z TAFS through 00Z Wednesday evening) Issued at 511 PM CST Tue Nov 30 2021

VFR conditions will continue throughout the TAF cycle with light and variable winds overnight. Southerly to southwesterly winds will become established again after 15z with some gusts up to 15 kts at times.
