Area Forecast Discussion National Weather Service Mobile AL 339 PM CDT Mon Oct 18 2021

NEAR TERM UPDATE /Now Through Tuesday/. Overall, upper ridging will maintain its hold over the region through the near term period. However, a weak shortwave is currently moving across the Deep South, bringing increased high cloud cover (and some midlevel clouds) along with it. As this feature weakens and dissipates through the day today and into this evening, clouds will be on the decrease for the overnight hours. Meanwhile, at the surface, high pressure will continue to progress east over the region and settle over the Appalachians by Tuesday morning. This will result in easterly flow becoming more southeasterly by Tuesday afternoon. Thus, return flow will begin to usher moisture back into the region. PWATs are well below an inch today, but will increase over coastal counties to be between 1.0-1.3 inches by late Tuesday afternoon.

For sensible weather, no rain and drier conditions will persist through much of the near term. Although, rain chances, albeit slight, will begin to increase over the Gulf waters Tuesday afternoon as moisture increases. Lows tonight will be a touch warmer compared to last night as we transition to easterly and eventually southeasterly flow (and moisture begins to increase). Therefore, temperatures in the upper 40s to lower 50s north of I-10 and the lower to upper 50s south of I-10 are expected. Some spots over far interior southeast Mississippi and southwest Alabama could possibly see cooler lows, closer to the mid 40s. Highs Tuesday afternoon will then likely be warmer as a gradual warming trend begins, with temperatures ranging in the mid 70s to around 80 degrees. Lastly, a LOW risk of rip currents will persist for area beaches through Tuesday, followed by a MODERATE risk beginning Tuesday night. /26

SHORT TERM /Tuesday night Through Thursday night/. Weak ridging over much of the eastern CONUS will flatten as a closed upper low over the north central Plains gradually shifts east into the Great Lakes region. The upper low is expected to weaken into a shortwave trough as if progresses east before being being absorbed by a larger upper low to its north. This setup will allow for weak southwesterly to zonal flow aloft to persist over the local area. At the surface, high pressure over the western Atlantic extends over the local area for much of the period before slowly retreating east Thursday night. Moisture will begin to increase Tuesday night as winds shift from easterly to more southeasterly, causing precipitable water values to increase into the 1.1 to 1.5 range. With the high dominating to the east, the chance for an isolated to scattered shower will be over the coastal waters and coastal Alabama coincident with where the greatest moisture will be. By Wednesday, the surface high starts to retreat and the moisture plume begins to spread inland. Isolated to scattered showers and storms will be possible across much of the area, with the greatest coverage (locally numerous) occurring over the southeast Mississippi and coastal Alabama. Precipitable water values continue to increase on Wednesday night into Thursday as they reach into the 1.6 to 1.8 range. The increased moisture in combination with a few shortwaves within the flow aloft will support scattered to numerous showers and storms during the day Thursday, with the greatest coverage occurring along the I65 corridor. Not expecting strong storms at this time given weak shear and marginal instability with SBCAPE between 1000-1500 J/kg. Scattered showers are expected to linger into the evening Thursday night ahead of an approaching surface front.

Lows start off in the upper 50s to lower 60s inland Tuesday night, but will rise into the lower to mid 60s by mid-week. Lows along the coast remain consistent in the upper 60s to lower 70s. Highs each day generally top out in the upper 70s to low 80s. /14

EXTENDED TERM /Friday Through Monday/. Zonal flow aloft will persist over the Southeast through the weekend as a larger, upper low meanders to the north of the Great Lakes region. An associated surface low over the Great Lakes meanwhile lifts off to the northeast and will trail a weak surface front into the Southeast early Friday morning. There is some uncertainty with whether the front will move through the forecast area. Deterministic EURO guidance indicates the front pushing offshore, but the GFS has the front dissipating before moving into the area which could be possible given the zonal flow aloft. Ensembles show a bit more consistency with the surface high pressure building back into the region over the weekend. For now, opted to lean more towards the ensembles and previous forecasts to keep consistency. This pattern would support dry and mild conditions through the weekend and into early next week. Temperatures should reach into the lower to mid 80s with lows generally in the upper 50s to lower 60s. /14


MARINE. From midweek through late week, higher winds and waves are expected in an around isolated to scattered showers and thunderstorms. Light to moderate east winds will persist until southeast flow takes hold by Tuesday evening. Seas will also increase from 2-3 feet to 3-4 feet Tuesday night through Wednesday, but are expected to subside to be around 2-3 feet through late week. Conditions may warrant the need for operators of small craft to exercise caution over Southern Mobile Bay, Mississippi Sound, and the open Gulf waters Tuesday into Wednesday. Winds become more southerly on Thursday as a cold front approaches from the northwest. Winds may shift to be northerly late in the week if the cold front moves southeast of the marine area and does not stall over the coast. Light to moderate easterly flow is then expected to develop for the weekend. /26
