Area forecast discussion, Mar 20, 3:57 PM CDT, 2 hours 10 minutes before
Area Forecast Discussion National Weather Service Mobile AL 357 PM CDT Fri Mar 20 2020 .NEAR TERM UPDATE /Now Through Saturday/...An upper level ridge will weaken and move south as a weak cold front moves into the area this afternoon. Ahead of the front scattered to numerous showers and a few thunderstorms can be expected especially across northwest portions of the area. An isolated strong or severe storm is possible in extreme northwest portions of the area where SPC has outlooked a marginal risk. However, the threat is very low and barely enough to mention. The front sinks to the coast late tonight into Saturday and washes out as upper ridging rebuilds slightly. This will leave low end scattered showers and thunderstorms across mainly the southern half of the area on Saturday afternoon while some cooler and drier air moves into the northwest portions of the area. Lows tonight will range from the low 60s across the northwest to mid and upper 60s along the coast. highs on Saturday will be in the low 70s across the northwest to low 80s in the southeast part of the area. /13 && .SHORT TERM /Saturday night Through Monday night/...Scattered clouds capable of light to moderate falling hydrometeors will continue through the weekend and into the beginning of next week. The weak front that will move into the area during the near term period and stall across our area late Saturday night as the upper flow becomes more zonal through the weekend. A few shortwaves will pass through the northern stream on Sunday and Monday leading to scattered showers and storms across our area. While the surface boundary will be weak and begin to wash out, there should be still enough of an influence to lead to the best storm coverage centered around the boundary. A few rumbles of thunder will be possible each day, but nothing strong. Temperatures will continue to run a few degrees above average with mid to upper 70s across the area on Sunday and upper 70s to low 80s on Monday. Low temperatures will remain mild as well with steady southerly flow developing late Sunday afternoon. Lows will remain in the 60s with maybe a few 50s north of highway 84 on Saturday night. BB/03 && .EXTENDED TERM /Tuesday Through Friday/...The extended period looks to dry out again but before we can dry out one more quick shortwave is expected to bring some showers and storms on Tuesday through Wednesday. A strong shortwave trough will quickly eject out of the Central Plains and into the Great Lakes region on Tuesday. This will lead to scattered showers and storms to develop across the area. Further west on Wednesday an deep upper trough will begin to dig over the western US. This will lead to the upper ridge centered over the Bay of Campeche to build into the central Gulf late Wednesday and Thursday. As the ridge builds the upper flow will be pushed further north and rain chances will drop to near zero. With continued southerly flow, temperatures will slowly warm throughout the week into the mid 80s by Wednesday. As the upper ridge begins to build and some subsidence moves over the area, expect temperatures to climb a little quicker and our first run at 90 could be possible late next week before the ridge moves east and flattens out with the ejecting trough over the western US. BB/03 && .MARINE...A surface ridge stretching west from the Atlantic over the northern Gulf coast will bring a mostly light to at times moderate southerly flow to area waters through tonight. A weak front will move south toward the tonight into Saturday, stalling along the Gulf coast. This will maintain the onshore flow through the late weekend and into early next week, increasing by the middle part of next week. Seas will remain 2 to 4 feet through much of the period. /13 && .MOB WATCHES/WARNINGS/ADVISORIES... AL...High Rip Current Risk through late tonight for ALZ265-266.
