Area Forecast Discussion National Weather Service Huntsville AL 503 AM CST Mon Dec 6 2021 .UPDATE... For 12Z TAFS. && .NEAR TERM...(Today) Issued at 249 AM CST Mon Dec 6 2021 The main impact in the short-term will be the potential for severe weather later this morning in the 6am to noon timeframe as a cold front moves into the area. The main impacts from any strong to severe storms will be isolated damaging wind gusts and the threat for a tornado or two, mainly across northwest Alabama. For more details see below. A mild and muggy early December morning across the Tennessee Valley with temperatures in the low to mid 60s and dewpoints in the upper 50s to low 60s. Southerly to southwesterly winds are also strong this morning ahead of the approaching cold front with some gusts to near 30 mph at times. Radar imagery indicates a few light showers across the area. There is another line of showers and storms developing ahead of the front that currently stretching from near Clarksville, TN to near Memphis, TN. Further to the west, there is a more organized line of showers/storms along the actual front that stretches from near Cincinnati, OH southwest to near Paducah, KY to near Little Rock, AR. The upper level pattern features a trough located to the north and west moving across the Great Plains into the western Great Lakes and Mid and Upper Mississippi River Valley. At the surface, the main low is located well to the north across the Great Lakes. Current forecast model soundings indicate strong low- level shear ahead of the front but rather significant capping around 800 mb. This cap will slowly erode as the front approaches. Models forecast that the upper level jet along the eastern periphery of the 300 mb trough will strengthen in the 09-12z timeframe. The low-level jet at 850 mb will increase in response. Some of the CAMs indicate a strengthening of the line of showers/storms along the cold front as well during this time as the line approaches northwest Alabama. Low- level and deep-layer shear remain impressive and low-level flow does not appear to veer as much as shown the last few days. Due to this, low level 0-1 km SRH stays up in the 250-350 m2s2 range along the frontal boundary. Model soundings indicate the capping eventually erodes just ahead of the front. Due to the early morning timing, instability is never all that impressive throughout the morning hours with MLCAPEs generally less than 250 J/Kg. Low-level 0-3 km lapse rates are not all that impressive at all with slightly better mid- level lapse rates. Overall, it appear that an isolated damaging wind gust will be the main threat with winds just above the surface over 50 kts. Additionally, a tornado or two cannot be ruled out this morning, especially over northwestern Alabama. The low-level jet quickly lifts out later this morning as the line progresses to the south and east. Much drier and cooler air will move in quickly behind the departing front. Rainfall amounts with the front will only range from around 0.5-1.0 inches and do not anticipate any flooding concerns. Northwesterly winds will be gusty behind the front as well with gusts up to 25 mph or so this afternoon with temperatures dropping into the 40s by sunset. .SHORT TERM...(Tonight through Wednesday) Issued at 249 AM CST Mon Dec 6 2021 Models have clearly trended towards a cooler and drier solution for the short-term period. The cold front will continue southward tonight as surface high pressure passes to the north. The pressure gradient from the high to the north and front to the south will be strong enough to keep winds up around 5 mph overnight. Overall, the cold air advection should be strong enough to push temperatures down into the upper 20s to low 30s. The surface high pressure will shift off to the northeast on Tuesday and will be centered across the eastern Great Lakes. The cold front will remain stalled to the south along the northern Gulf Coast. PW values will be in the 0.5-0.6 inch range. These values are near the climatological mean for early December. Overall, things have trended drier on Tuesday with the front remaining to the south. Highs will be on the cooler side in the upper 40s to low 50s. Still seeing some rather large differences in the models for Tuesday night into Wednesday. An upper level trough will approach from the west with an area of low pressure developing along the stalled boundary to the south. There are clear differences about how far north the front and moisture will progress. The GFS continues to be the furthest north with the moisture. About half of the GFS ensemble members indicate light rain for the Tennessee Valley on Wednesday but the other global models and their ensembles keep things dry. Therefore, have a 20-30 PoP in the forecast for Tuesday night into Wednesday but this is much lower than just a few day ago with a clear drier trend. .LONG TERM...(Wednesday night through Sunday) Issued at 249 AM CST Mon Dec 6 2021 Height rises are forecast as this mid-week trough exits to the east. A strong warm air advection regime will take place for much of the extended as the warm front finally does push northward on Thursday. There could be a few showers or storms with this warm front lifting northwards on Thursday. Temperatures will start to climb with highs on Thursday in the upper 50s to mid 60s. Unseasonably strong warm air advection will begin to take place on Friday with low-level southerly flow increasing ahead of a front racing across the Great Plains on Friday. Some models indicate dewpoints climbing into the mid 60s on Friday with highs well into the mid to may be even upper 70s. For now, have PoPs around 50% for Friday with showers and storms developing in this warm sector. With this being several days out, still not sure how much lift there will be in this warm sector but it will be anomalously warm and moist for early to mid December. The global models are starting to coming into better agreement for Saturday. The placement and timing of the upper level trough and surface features looks very similar to the system this morning. The cold front will move into the Tennessee Valley early Saturday morning with the surface low well displaced to the north. The main difference between this system and todays is that the dewpoints look to be a good bit higher. Both the raw GFS/ECMWF both have dewpoints in the mid to upper 60s early Saturday. This could lead to a bit more interesting setup for severe weather this weekend. Overall, this system is still several days away but will add the mention of the possibility of severe storms with this system into the HWO. This system looks to move through quickly with cooler and drier air moving in later Saturday and into Sunday. && .AVIATION...(For the 12Z TAFS through 12Z Tuesday morning) Issued at 503 AM CST Mon Dec 6 2021 A line of storms ahead of a cold front are quickly approaching the terminals this morning. TSRA should be knocking on the door at MSL at the start of the TAF period around 12z. These storms will bring strong winds up to 40 kts and frequent lightning. These storms will approach HSV around 13z and will continue quickly eastward. Ceilings will generally be MVFR this morning before much cooler and drier air moves in behind the front this afternoon. Winds will remain gusty throughout the TAF period with southerly winds ahead the front transitioning to northwesterly by this afternoon. Gusts into the 20-25 kt range will be common throughout the TAF period. Drier air moving in behind the front will improve ceilings to VFR by 16z at MSL and by 19z at HSV. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
