Area Forecast Discussion . UPDATED National Weather Service Mobile AL 639 AM CDT Sat Apr 4 2020

AVIATION. 12Z issuance . VFR conditions prevail through 05.07z, followed by MVFR ceilings through 05.12z. Light northerly winds are expected through this evening, except for a southerly flow around 5 knots developing in the afternoon over the coastal counties. /22

PREV DISCUSSION. /issued 409 AM CDT Sat Apr 4 2020/

NEAR TERM UPDATE /Now Through Sunday/ . Broad upper ridging over the region weakens leaving a zonal flow pattern within which a series of modest shortwave progress across the area. A large surface high over the central states begins to build into the eastern states during the period while a surface low off the mid Atlantic coast moves further off into the Atlantic. This will promote a light northerly surface flow over the forecast area, except for a modest sea breeze which develops this afternoon. With the weakening of the broad upper ridge over the region, subsidence effects wane allowing for deep layer moisture to increase, with model soundings showing a pronounced moistening trend through tonight. Expect dry conditions to continue over the area through this evening, then given the generally weak nature of the shortwaves, will have slight chance pops return south of US Highway 84 after midnight. This precipitation will taper off from north to south through Sunday morning, followed by dry conditions in the afternoon as a weak surface ridge builds in from the north.

High temperatures over the weekend will be in the low to mid 80s, except for upper 70s along the immediate coast. Lows tonight will be mild, ranging from 58 to 63 degrees. A low risk of rip currents continues through Sunday. /29 /22

SHORT TERM /Sunday night Through Monday night/ . The short term overall looks dry but will be the building blocks to an overall more active pattern as we head into the extended period. By Sunday night, broad upper ridging will build in the wake of the weak shortwave that moves through Sunday. This will be in response to a large upper trough digging along the Pacific coast and a weak shortwave ejecting over the southern plains. This will allow for the surface high to strengthen over the western Atlantic bringing better moisture to the area. Sunday through Monday morning will be dry but showers and storms will likely increase by the afternoon west of I-65. This will be in response to the weak shortwave beginning to nose into the area. Scattered shower and a few storms will slowly spread eastward across our area through Monday night with the best chances of precip north of highway 84.

As for temperatures, with the slowly building ridge across the area I would expect temperatures to be on the warmer side. Highs will be in the low to mid 80s with the warmest temperatures on Monday. Lows will also be on the rise with the increasing southerly wind advecting in better gulf moisture. Expect lows to slowly climb back into the low 60s. BB/03

EXTENDED TERM /Tuesday Through Friday/ . An upper ridge persists over the southern and central Gulf of Mexico through the period along with surface high pressure over the western Atlantic and eastern Gulf. This pattern results in an unsettled, generally zonal flow aloft and a moist southerly flow in the low levels. As such, expecting showers and thunderstorms each day through the period, with focus over inland areas where coverage is expected to be greatest. At this time, there appears to be enough deep-layer flow for at least weak convective organization potential during afternoon hours each day. Any stronger storms would be capable of producing gusty winds, though uncertainty remains as a true forcing mechanism is lacking aside from daytime heating and a series of weak upper impulses passing to our north. Still, will continue to monitor strong storm potential and update as needed, particularly if temperature guidance verifies and summerlike heat and instability are realized across the region.

Regarding the temperatures, highs warm into the mid and upper 80s by midweek as dewpoints climb into the upper 60s and low 70s. It will feel more like late May or early June than early April. Lows remain mild and muggy in the upper 60s and even low 70s for some. /49

MARINE . Weak zonal flow aloft will lead to a light to occasionally moderate diurnally driven flow through the weekend. Offshore flow will develop overnight becoming a south-southeasterly flow during the afternoon. A weak upper level trough will approach Monday night into Tuesday leading to light to occasionaly moderate onshore flow developing ahead of a weak bounday. Wind will become southwesterly through the middle of next week. A few showers could be possible on Sunday but rain chances will be low. BB/03
