Near Term
(Now through Friday) Issued at 406pm CST Thu Dec 1 2022

Cool and dry conditions will persist through Friday with high pressure over the southern Gulf leading to mostly zonal flow. Low level moisture and low stratus clouds will slowly increase across western 2/3rds of the forecast area on Friday along the western periphery of a surface ridge across the southeast states. Temps are the main part of the forecast with lows ranging from 35 to 41 degrees inland, from 41 to 46 degrees across the coastal zones, with upper 40s to lower 50s at the beaches. Highs on Friday will range from 65 to 70 degrees. /22

SHORT TERM... (Friday night through Sunday night) Issued at 406pm CST Thu Dec 1 2022

Zonal to west-northwesterly flow aloft will be in place through the period as an upper-level ridge builds over the western Gulf and upper-level troughing sets up over the Northern US. At the surface, a weak cold front is expected to push through the area on Saturday and move into the northern Gulf by Saturday night. With PWATs (Precipitable Waters) increasing to around 1.3 to 1.6 inches, isolated to scattered showers and a few thunderstorms will be possible as the front pushes through. Although severe storms are not expected at this time, cannot rule out one or two stronger storms capable of producing gusty winds, due to dry mid level air giving way to DCAPEs (Convective Available Potential Energy - high values indicate potential for severe weather) of around 700 to 900 J/kg. By Sunday, the front will begin to slowly lift back to the north as a warm front. With ample moisture still in place, a few isolated showers can be expected across the area on Sunday. Highs will be in the low to mid 70s on Saturday, decreasing slightly to the upper 60s to low 70s on Sunday. Lows will generally be in the mid to upper 50s inland and lower 60s closer to the coast. A MODERATE risk of rip currents on Saturday will decrease to a LOW risk on Sunday. /96

Long Term (Monday through Thursday) Issued at 406pm CST Thu Dec 1 2022

The zonal to west-northwesterly upper-level flow pattern continues through the extended period as ridging remains in place over the Gulf and troughing remains over the northern US. A few shortwave impulses look to move within this flow throughout the period, with the bulk of this energy remaining just to the north of our local area (primarily along the Tennessee River Valley). At the surface, a warm front will continue to lift northward during the day on Monday as high pressure begins to build over the Florida Peninsula. This will help to maintain a southwesterly surface wind through Wednesday before a cold front begins to approach the region from the north. There are some model discrepancies with regards to how far south the cold front will make it before stalling - the GFS (Global Forecast System) being the more progressive model in pushing the front all the way down to the coast on Thursday, whereas the ECMWF (European Centre for Medium-Range Weather Forecasts) and the Canadian keep it in northern AL/MS. As far as sensible weather, a few isolated showers will be possible on Monday and Tuesday for the northern half of our CWA, due to the proximity of the shortwave impulses and PWATs (Precipitable Waters) close to 1.5 inches. Areas south should remain dry due to the ridging in place. Isolated to scattered showers will return to much of the area on Wednesday and Thursday as the front begins to approach the region (highest coverage over northern areas). Some limited instability may try to return to the area on Tuesday and Wednesday afternoons, and therefore added in a mention of thunder for these days. Temperatures through Wednesday will remain well above seasonal norms, with highs generally in the mid to upper 70s and lows in the low to mid 60s. Depending on the progression of the front, Wednesday night and Thursday may be a touch cooler. /96

Marine
Issued at 406pm CST Thu Dec 1 2022

Small Craft Should Exercise Caution headlines over the Gulf will be required through at least Friday. Otherwise, a light to moderate flow will shift easterly this evening into Friday, and then southeasterly to finish off the week. A more established light to moderate southerly to southwesterly flow will then occur Sunday afternoon through Tuesday. /22
