554 FXUS64 KMOB 040934 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 434 AM CDT Tue Jun 4 2024 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE... .NEAR TERM... (Now through Wednesday) Issued at 434 AM CDT Tue Jun 4 2024 We will continue to see a continuation of a series of impulses/shortwave disturbances moving in a west-northwest flow aloft to aid in the trigger for mainly diurnal convection over the next several days. A few showers and storms, the remnants of one of these disturbances, are moving east across the forecast area during the predawn hours this morning. This activity could last into the morning daytime hours on Tuesday, especially for our eastern and southern counties. Another convective system (associated with the next shortwave feature) has developed over Oklahoma early this morning, and will be the next system to drop east-southeast toward our area today and this evening. CAMs continue to show this MCS CS pushing across the ArkLaTex region this morning, and moving fairly quickly across Louisiana southern Mississippi in the afternoon, with remnants moving into southwest Alabama this evening before dissipating over the area by around midnight or just thereafter during the predawn hours Wednesday. It still appears that deep layer shear will be a bit stronger with this system today, which could bolster a better threat for strong to severe storms this afternoon SPC has a SLIGHT severe threat just to the west of our forecast area for today and tonight, with a MARGINAL severe threat over our western area (west of I-65), so a strong to severe storm or two could be possible this afternoon or evening. Yet another impulse will bring scattered showers and storms to the area again on Wednesday. Highs today will generally be in the upper 80s across most of the area (low to mid 80s at the coast) and then slightly warmer (in the upper 80s to lower 90s inland and mid to upper 80s coastal) on Wednesday. Lows tonight are expected to be in the upper 60s inland and low to mid 70s closer to and along the coast. DS/12 && .SHORT TERM... (Wednesday night through Thursday night) Issued at 434 AM CDT Tue Jun 4 2024 Similar pattern continues through the short term period, but models do indicate the potential for a stronger shortwave aloft to move across our area and Thursday morning. This will result in a less diurnal patter, with chances for showers and storms remaining higher Wednesday night, and continuing into Thursday. SPC just has general thunderstorms forecast for our entire area Wednesday night, but with the strength of the shortwave energy aloft there could again be a few strong to briefly severe storms (especially Wednesday evening/overnight) and again Thursday afternoon when instabilities are greatest. We will continue to monitor for this potential. Rain chances will be lower on Thursday night, and mainly confined to coastal locations. Lows both Wednesday and Thursday nights will range from lower 70s inland to middle 70s down along the coast. Highs on Thursday are expected to be mainly in the mid to upper 80s, but a few lower 90s possible over inland areas. DS/12 && .LONG TERM... (Friday through Monday) Issued at 434 AM CDT Tue Jun 4 2024 Upper pattern changes during the early part of the long term period, with an upper low developing over the Great Lakes region and a large upper trough developing over the eastern third of the CONUS. This pattern will allow a weak cold front to drop south across the area on Friday, with somewhat drier air behind the front. With the lower dewpoints and reduced deep layer moisture, rain chances will generally be lower in the long term even with a somewhat active northwesterly upper level flow persisting. Rain chances will mainly be diurnal in nature, with a 20 to 30 percent chance of rain each day. Daytime highs will continue to be in the upper 80s and lower 90s through the period. With the lower dewpoints, nighttime lows will be a little cooler Friday and Saturday nights, with mid to upper 60s over most inland locations and lower 70s along the coast. Sunday night min temps will generally be in the lower 70s inland and middle 70s for coastal locations. DS/12 && .MARINE... Issued at 434 AM CDT Tue Jun 4 2024 No significant marine impacts are expected throughout the week. Light onshore flow prevails through midweek and then shifts westerly late in the week. /22 MM/25 && .PRELIMINARY POINT TEMPS/POPS...
