Area Forecast Discussion
...UPDATED National Weather Service Mobile AL
611am CDT Wednesday Oct 21 2020

NEAR TERM UPDATE /Now Through Thursday/...An upper ridge over the southeastern states begins to retreat into the western Atlantic during the period as a broad upper trough over the northern CONUS gradually amplifies over the central states. A surface ridge over the southeastern states gradually weakens resulting in light northeasterly winds over the forecast area becoming easterly on Thursday. The presence of the upper ridge over the region looks to produce sufficient subsidence to go with a dry forecast today, although a stray shower/storm cannot be ruled out. As the upper ridge begins to retreat for the area on Thursday, model soundings show modest mid level cooling (less subsidence) sufficient to support mostly slight chance probability of precipitation over the entire area on Thursday initiated by a combination of daytime heating and a weak sea breeze. Some patchy fog will be possible early this morning and again late tonight mainly over interior areas. Highs today and Thursday will be in the mid 80s which are about 10 degrees above seasonable values, and lows tonight will be rather mild and range from the mid 60s inland to around 70 at the coast which are about 15 degrees above normal. A high risk of rip currents continues through the period mostly due to an onshore swell of 2-3 ft near 7-8 seconds. /29

SHORT TERM /Thursday night Through Friday night/...An upper level trough quickly ejects over the northeastern states as another trough moves across the northern states through Thursday. The nose of a surface ridge of high pressure remains rooted over the southeastern United States. A weak upper level trough approaches the area Thursday into Friday, and with ample deep layer moisture present this should help to spark off showers and thunderstorms during the period. The best chance for showers and thunderstorms appears to be on Friday afternoon into Friday evening, where Probability of Precipitation has been raised to 60% for most areas. As the upper level trough passes the area Friday night, expect shower and thunderstorm chances to decrease. Unseasonably warm weather persists this period, with overnight lows in the middle to upper 60's both Thursday and Friday night, and highs in the lower to middle 80's Friday. MM/25

EXTENDED/Saturday through Tuesday/...An upper level shortwave trough over the Southeast moves off Saturday into Sunday, with a surface cold front sagging south over the Southeast in response. Latest guidance is advertising the front sagging to near I-65. Sunday into the middle of the coming week, an upper level trough digs south over the western Conus, eventually forming a close upper low over the Desert Southwest. An upper level ridge builds north over the Southeast, with a surface ridge re-building west over the Southeast in response. Some precipitation lingers over the forecast area Saturday into Saturday night before drier weather sets in. The airmass remains moist over the Southeast through the latter half of the weekend into the coming week, but as the low level ridge becomes better organized, moisture levels increase into mid week. Best chance of rain will be northwest of I-65 as a second cold front begins to sag south across the Southeast Tuesday. With the building ridge over the Southeast, temperatures a bit above seasonal norms Sunday quickly rise to well above in the coming week. /16

MARINE...Periods of Small Craft Exercise Caution conditions are possible over the open Gulf waters through Thursday night into Friday well offshore, due to a moderate to occasionally strong easterly flow. /29
