Area Forecast Discussion National Weather Service Mobile AL 329 PM CDT Tue Jul 14 2020

NEAR TERM UPDATE /Now Through Wednesday/. Scattered thunderstorms are ongoing across the area at this time and will continue through this evening before dissipating after dark. The environment still supports wet microburst potential given moist boundary layers, dry air aloft, and plenty of instability. As a result, some of the stronger storms this afternoon could be capable of producing locally damaging wind gusts in addition to the typical summertime hazards of frequent lightning and heavy downpours. Have already noted this potential in a few thunderstorms this afternoon. The deep-layer wind profile remains weak, meaning storm motion will be slow and heavily dependent on initiating boundaries/outflows, so cannot rule out a few instances of minor flooding and ponding in areas that see heavy rain persist for more than an hour. A Heat Advisory remains in effect for portions of southeast Mississippi and coastal counties until 7 pm CDT this evening.

Quiet weather is expected tonight with lows remaining in the mid 70s inland and upper 70s along the coast. A weak upper low pinches from a departing mid-latitude trough and retrogrades southwestward over the local area on Wednesday. Height falls associated with this low will help support a greater thunderstorm coverage Wednesday morning through Wednesday evening, with PoPs increasing to around 60-70% for much of the area. Could once again see a few instances of locally damaging wind gusts and minor flooding issues in the heavier storms. Temperatures on Wednesday will remain a few degrees cooler than the past few days thanks to the increased coverage in rain and clouds. Highs reach the upper 80s to low 90s/ Heat indices are expected to stay below advisory criteria, around 100 to 105 degrees. /49

SHORT TERM /Wednesday night Through Friday night/. An upper level easterly wave over the region Wednesday night will migrate westward over the north central gulf and lower Mississippi River on Thursday, then reach the northwest Gulf and southeast Texas by late Thursday night. This will maintain scattered to numerous showers and thunderstorms on Thursday. A large upper level ridge of high pressure builds from the Southern Plains eastward across the Tennessee Valley into the Mid Atlantic States on Friday. The increased upper heights along with some drier air will decrease rain chances to more of a typical pattern. Showers and thunderstorms will start near the coast in the morning, developing inland through the day. Coverage will be most numerous during peak heating before decreasing during the evening hours as the boundary layer cools.

Hot and humid conditions continue with low to mid 90s for high temps and little change in the muggy overnight lows. /13

EXTENDED TERM /Saturday Through Tuesday/. An easterly mid level flow prevails through the extended term period as a mid level high pressure ridge becomes entrenched to the north of our forecast area. Meanwhile, weak high pressure at the sfc will maintain a weak flow pattern. The winds will primarily be diurnally-driven with the daily sea/land breeze cycle and afternoon heating through the period. Daily thunderstorm chances continue to hover around 30-50 percent through the weekend into next week as weak disturbances embedded within the easterly flow aloft pass over the area and act on a moist and moderately unstable boundary layer. The coverage of showers and storms will be focused along the sea breeze near the coast each late morning into early afternoon and then farther inland during the late afternoon and early evening hours.

Daytime temperatures will continue to hover in the low to 90s, with heat indices remaining in the 100 to 107 degree range. Lows will continue to be in the low to 70s over the interior and in the upper 70s near and along the coast each night. /13

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
