084 FXUS64 KMOB 300844 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 344 AM CDT Tue Apr 30 2024 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE... .NEAR TERM... (Now through Wednesday) Issued at 342 AM CDT Tue Apr 30 2024 A fairly vigorous shortwave through axis is moving east across the forecast area this morning, and has initiated another round of showers and a few isolated thunderstorms over portions of the area, especially down near the coastal areas of MS and AL. This newer round of convection is somewhat limited in coverage however, partially due to the stabilizing effect of the previous remnant MCS boundary that moved across the area Monday evening. This area of convection will spread east across the forecast area through the morning hours, likely extending further inland with heating after sunrise as the shortwave axis continues east across the area. The orientation of the rain axis will allow for some training of heavier cells, with some brief heavy rainfall rates possible at any one location as the precip moves east across the area. Some brief localized ponding of water on roadways and poor drainage areas could be possible this morning, but no widespread flooding is expected. Severe storms are not expected. By early this afternoon, the shortwave axis will be east of our area and rains will end and skies will begin to clear from west to east. Low to mid level ridging will build over the forecast area in the wake of the shortwave, and no rain is expected from late this afternoon through Wednesday. High temperatures today should be in the lower 80s for most locations, but some mid 80s over interior southeast MS (where we will likely see longer duration of direct sunshine) and only mid to upper 70s near the beaches with a moderating onshore wind flow coming in off the Gulf. Lows tonight mainly in the lower 60s, but some upper 60s to lower 70s possible along the beaches and barrier islands. It will be warmer on Wednesday, with highs ranging from the mid and upper 80s over most interior locations but low to mid 80s closer to the coast. DS/12 && .SHORT THROUGH LONG TERM... (Wednesday night through Monday) Issued at 342 AM CDT Tue Apr 30 2024 n the wake of an exiting shortwave trough over the Southeast, an upper ridge builds north over the eastern Conus. Deep layer southerly flow becomes organized through the latter half of the week, bringing Gulf moisture inland. The influx of moisture is well west of the forecast area mid week, but shifts eastward into the weekend. A series of shortwave troughs pass Friday through Sunday. The upper ridge maintains enough strength to deflect the bulk of the energy north of the forecast area, limiting best PoPs to northwest and northern portions of the forecast area with each passing trough, along with limiting rain chances to isolated to low end scattered. Subsidence from the upper ridge will help to keep temperatures above to well above seasonal norms through the period. High temperatures in the mid 80s to near 90 well inland with around 80s south of I-10 to the coast are expected. Low temperatures are expected to range from around 60 to the low 60s north of Highway 84 to mid 60s/upper 60s closer to and along the coast. /16 && .MARINE... Issued at 342 AM CDT Tue Apr 30 2024 Strong winds that resulted from a wake low Monday evening are rapidly subsiding over the marine area. Seas offshore, up to around 5 feet this morning, could be hazardous to small craft, but by this afternoon and through the remainder of the week no hazards are expected. Winds and seas will continue to decrease this morning, with a light southwesterly flow anticipated by this afternoon. High pressure passing over the area midweek will lead lighter and more variable winds. A light onshore flow will then develop over the marine area for the latter part of the week and into the early part of the weekend. DS/12 && .PRELIMINARY POINT TEMPS/POPS...
