725 FXUS64 KMOB 181922 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 222 PM CDT Thu Jul 18 2024 ...New NEAR TERM, SHORT TERM, LONG TERM, MARINE... .NEAR TERM... (Now through Friday) Issued at 222 PM CDT Thu Jul 18 2024 Scattered to numerous showers and thunderstorms remain expected this afternoon and evening, with isolated to scattered coverage into the overnight hours. Upper troughing over the eastern CONUS stretches down into the forecast area, with a notable shortwave transiting the base of this trough this afternoon and evening. This feature will serve as the focus for thunderstorms working in tandem with a surface front that is sluggishly working its way southeast into the forecast area. PWATs remain in the 2 to 2.4 inch range, promoting very heavy rainfall with any showers and storms. Training convection could lead to isolated instances of flash flooding, particularly in urban and low lying areas similar to what we saw this morning in Okaloosa county. High temperatures should manage lower 90`s for the rest of today before increased cloud cover and thunderstorm coverage helps to keep temperatures in check. Overnight tonight temperatures fall into the lower to middle 70`s inland and middle to upper 70`s nearer the coast. As we head into the day Friday we will likely see the aforementioned shortwave continuing its slow progression eastward across the forecast area. Once again numerous showers and thunderstorms are expected by mid to late morning, lasting through the afternoon and evening hours as convection spreads inland. Similar hazards can be expected with storms Friday featuring heavy rainfall and flash flooding concerns in urban and low lying areas, particularly in any spots that see notable rainfall from the previous day. Either day can`t rule out a stronger pulse-type storm or two with gusty winds and small hail. Highs Friday will be cooler generally in the middle to upper 80`s for all locations. Friday night temperatures once again dip to the lower to middle 70`s inland and upper 70`s nearer the coast. A LOW risk of rip currents remains in place through Friday night. MM/25 && .SHORT AND LONG TERM... (Saturday through Thursday) Issued at 222 PM CDT Thu Jul 18 2024 We have entered a stagnant upper air pattern as an upper trough extending from southeast Canada to the southern Plains remains nearly stationary two bookend upper ridges. Meanwhile a surface ridge over the northern Gulf becomes a bit better organized through the weekend into the coming week. The steady onshore deep layer flow keeps moisture levels high over the Southeast (precipitable h20 levels above 2"). Through the weekend into the coming week, it is pretty much the same story/different day. Showers and thunderstorms initiate south of the northern Gulf coast in the overnight hours into the first few hours after sunrise. From there, a short lull in the morning with convection again increasing in coverage over inland areas of the Southeast is expected. For the forecast area, a few storms may become strong to marginally severe, though modest instability keeps the risk low. There continues to be a risk of water issues, with the scattered to numerous daytime coverage of efficient rainers. The forecast area can handle more rain this time of the year due to the summer time growth, but if a locality sees several training cells, there may be ponding to low end flooding issues. Also, an extended period of rain may help to keep soils more moist than usual, decreasing absorption. Will need to monitor. With average upper level heights (and modest upper subsidence) combined with daily rain, temperatures around to below seasonal are expected through the weekend into the coming week. High temperatures in the upper 80s to low 90s are expected through Wednesday, with low temperatures in the low to mid 70s north of I-10, mid 70s to near 80 south to the coast. Heat indices remain well below advisory criteria, topping out at or below 102 degrees each day. Beach Note: A LOW risk of rip currents is expected to continue through Monday afternoon. Guidance is advertising onshore flow becoming more organized and a bit strong, bringing increasing swell to area beaches and a MODERATE risk of rip currents Monday night into mid week. /16 /22 && .MARINE... Issued at 222 PM CDT Thu Jul 18 2024 Locally higher winds and seas possible near thunderstorms through the weekend and into next week.
