NEAR TERM. (Tonight) Issued at 229 PM CST Fri Jan 28 2022

Northwesterly winds remain gusty across the area this afternoon with gust to around 25-30 mph at times. Temperatures have warmed into the low to mid 40s under mostly sunny skies. There are some temperatures in the upper 30s across northeast Alabama where cloud cover stuck around a bit longer today. The arctic boundary is still to the north and is nearing the I-40 corridor. The upper level pattern features a couple of shortwave troughs. One to the northwest across the Mid- Mississippi River Valley and another elongated trough stretching across the Lower Mississippi River Valley southwestward into Texas. These troughs will phase later this evening/tonight and will lead to an impressive Nor'easter across New England later this weekend.

Closer to home, this upper level trough will move over the area later this afternoon/evening around 00z. The atmosphere is very dry right now with PW values around a tenth of an inch. Models indicate that moisture does increase a bit around 00z with PW values around a quarter of an inch. This will occur as the arctic front pushes through the forecast area. Temperatures at 850 mb will plummet as the front pushes through creating rather impressive low-level lapse rates. Some models indicate SBCAPE values around 50-100 J/Kg. The northwesterly flow will also aid in orographic lift across portions of southern Middle Tennessee and northeast Alabama. Models soundings also indicate saturation up into the snow growth zone with some lift in this layer. Overall, the ingredients for snow are all there but there is not much moisture to work with. These ingredients look to all overlap in the 22z- 02z timeframe. Expect most locations will see a few flurries but only expect the potential for accumulations across the higher elevations of northeast Alabama and southern Middle Tennessee. In these locations, expect there will be a few isolated spots that could see up to half an inch of accumulation. Due to the limited coverage and low confidence, do not expect to issue any winter weather products but will add this into the HWO.

The main story for tonight will be the cold. Strong northwesterly winds will remain gusty behind the departing arctic boundary. These winds will gust into the 20-30 mph range at times overnight. Temperatures will drop down into the upper teens and low 20s. The combination of winds and cold temperatures will lead to windchill readings down in the single digits. Spots in the higher elevations could have below 0 windchills late tonight. Once again, not widespread enough for a wind chill advisory, regardless, take extra precautions to stay warm if you must be outside late tonight into early Saturday morning.

SHORT TERM. (Saturday through Sunday) Issued at 229 PM CST Fri Jan 28 2022

Saturday will be bitterly cold with northwesterly winds continuing to advect in colder air into the region. Upper level heights will be on the rise as the upper trough departs to the east. Skies will be mostly sunny with a bone dry atmosphere in place. Despite the ample supply on sunshine, temperatures will struggle to make it out of the mid 30s. The surface high pressure will pass to the north of the area on Saturday with light southwesterly flow by Saturday night. Expect decent radiational cooling conditions Saturday night into Sunday morning with light winds and clear skies. Dewpoints will be extremely low Saturday afternoon down in the single digits. Therefore, expect overnight lows Saturday night into Sunday morning will be down in the low to mid 20s for most locations. The windchill values will not be as bad in the upper teens to low 20s.

Upper level heights will continue to climb on Sunday with light westerly to southwesterly low-level flow. Upper and mid-level flow will be from the northwest with troughing to the east of the area. The dry airmass will persist with PW values down near a quarter of an inch. Mostly sunny skies will warm highs up into the low to mid 50s.

LONG TERM. (Sunday night through Thursday) Issued at 229 PM CST Fri Jan 28 2022

The warming trend will continue into next week. Warm air advection will begin to increase on Monday with temperatures climbing into the mid to upper 50s, a few locations may make it to 60. The shortwave ridge axis aloft will shift to the east of the area late Monday with southwesterly flow aloft. Persistent low-level southerly to southwesterly flow will feature as well. Temperatures will continue to warm on Tuesday with highs into the upper 50s to low 60s. Latest model trends between all the 12z guidance has really backed off on precipitation chances on Tuesday. Due to this, did not start PoPs until Tuesday night and this may even be too soon based on some model guidance.

In the extended forecast, a northern stream system tracks across southern Canada with an associated cold front stretching to the south. This cold front will bring in another blast of arctic air across the Great Plains and MidWest. This northern stream trough will race eastward abandoning the front to the north and west of the forecast area. Later in the week, a southern stream trough will develop as an area of low pressure develops along this front. Precipitation chances will be on the rise on Wednesday and Thursday as this surface low and front approach the area. For now, have just mentioned showers but there could be a few thunderstorms depending on the track of the system. Temperatures will continue to be on the warmer side on Wednesday with highs in the low 60s. The front will bring another blast of cold air to the Tennessee Valley to end the week. The warm up early next week will in no way be the end of winter.

AVIATION. (For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1100 AM CST Fri Jan 28 2022

VFR conditions will continue throughout the TAF cycle. Northwesterly winds will remain gusty throughout the TAF period with some gust to near 25 kts at times. Winds should subside some late in the TAF cycle.
