NWS Mobile, AL wrote its last area forecast discussion before the first event at Jul 1, 2:45 PM CST, 2 hours 29 minutes earlier.
Area Forecast Discussion National Weather Service Mobile AL 345 PM CDT Wed Jul 1 2020 .NEAR TERM UPDATE /Now Through Thursday/...The axis of an upper trof which extends from near the mid Mississippi River valley to the Virginias (and to an upper low over the extreme northeast states) shifts southward through Thursday into the forecast area. A surface low is currently located near the Kansas/Oklahoma border with a frontal boundary extending eastward across Missouri. With the southward progression of the upper trof, the frontal boundary follows suite and shifts southward to extend across northern Mississippi and northern Alabama by Thursday. The upper trof pattern has set up a northwesterly steering flow over the region such that convection that develops along the frontal boundary will be favored to progress southward/southeastward in the general direction towards the forecast area. The current satellite loop shows two convective complexes have formed within this regime, one of which has weakened over the area and produced an outflow boundary while another is actively ongoing in Missouri. The outflow boundary has advanced into the northern portion of the forecast area and expect scattered to numerous convective development through the afternoon hours in response to this feature and also aided by a weak sea breeze. MLCAPE values are expected to be near 2000 J/kg in a fairly moist environment with precipitable water values near 2.0 inches and wet bulb zero values near 13.5 kft. 0-6 km bulk shear values look low, 20 knots at best, so am expecting the primary initiating mechanism for stronger storms to be from precipitation loading. The attention now turns to what will transpire with the convective complex over Missouri along with the southward progressing upper trof and frontal boundary. This convective complex appears to have already formed another outflow boundary which is expected to progresses roughly southward. While not handled particularly well by high resolution guidance or Convection Allowing Models (CAMS), the expectation is that this next outflow boundary will follow a similar evolution to the current one and continue southward into the area late tonight. Complicating this pattern is that yet another convective complex may develop on the frontal boundary advancing into northern Mississippi/Alabama. All in all, there look to be at least a few possible scenarios for convective development for Thursday which in turn supports going with higher pops, and have gone with likely to categorical pops for nearly the entire area. A moist environment remains in place over the area on Thursday with precipitable water values near 2.0 inches, and wet bulb zero values are expected to trend higher to around 14 kft. 0-6 km bulk shear values look to be less than 20 knots, so while MLCAPE values near 2500 J/kg are indicated this environment looks more supportive of general thunderstorms with an occasional strong storm possible. Lows tonight range from the lower 70s inland to the upper 70s at the coast. Highs on Thursday range from the mid 80s well inland, such as near Highway 84 to upper 80s/lower 90s elsewhere. Heat index values this afternoon will be around 105 in some locations, then look remain in a range of 95 to around 105 on Thursday. A low risk of rip currents is expected through Thursday. /29 && .SHORT TERM /Thursday night Through Saturday night/...An upper level trough over the northeastern CONUS will continue to dig south, with a section of this trough digging from northeast to southwest over the southeastern CONUS through late week. A slow- moving surface front will also progress southward over the southeastern CONUS through Saturday morning before stalling near the northern Gulf coast through Saturday night. The aforementioned pattern will lead to continued unsettled and wet weather through the short term period, albeit still somewhat diurnal. Scattered showers and storms are likely during the overnight hours, with increasing chances during the afternoon each day. PWATs are shown to be just under 2 inches to around 2.3 inches through Saturday night, leading to forecast storm total rainfall ranging from 0.50-1.5 inches. Thus, The Weather Prediction Center has outlooked southeast Mississippi, southwest and south-central Alabama, as well as the western Florida Panhandle in a marginal risk for excessive rainfall Thursday and Friday. In addition, MLCAPE values between 1000-2000 J/kg in the afternoon and between 500-800 J/kg during the nighttime will keep the potential for embedded thunderstorms through the short term as well. Warm and muggy conditions will comprise the short term, with high temperatures Friday and Saturday afternoons a touch cooler, in the mid to upper 80s, due to cloud cover. Although, a few spots could reach 90 degrees Friday afternoon. Meanwhile, overnight lows Thursday night through Saturday night will continue to be warm. Temperatures are expected to only dip into the lower to mid 70s north of I-10 and in the mid to upper 70s south. Lastly, there is a LOW RISK of rip currents through Saturday night. /26 && .EXTENDED TERM /Sunday Through Wednesday/...An upper level low is expected to form over the southeastern CONUS and persist through much of the extended term. Meanwhile, upper level high pressure will build over the eastern Gulf of Mexico into midweek next week. At the surface, the front that stalled close to the northern Gulf coast will weaken as low pressure forms over the Deep South. This low will eventually progress over South Carolina by Tuesday morning and then move off over the Atlantic by midweek. By this time, high pressure is expected to build over the eastern Gulf of Mexico. Model PWATs are shown to be right around 2 inches to about 2.3 inches through much of extended period, with exception of Tuesday where values are shown to be less (around 1.5-1.8 inches). Thus, the unsettled and wet pattern will persist through early next week. However, with PWATs decreasing into midweek, chances for showers and storms could start to decrease by this time. This will continue to be monitored. Continued warm and muggy conditions are expected through midweek next week. High temperatures will be in the mid to upper 80s Sunday through Tuesday afternoons, with some areas along and south of I-10 potentially reaching 90 degrees by Wednesday afternoon. Lows Sunday through Tuesday nights will likely be in the lower to mid 70s north of I-10 and in the mid to upper 70s south. /26 && .MARINE...No impacts are forecast except winds and waves higher near isolated to scattered showers and thunderstorms. /29 && .MOB WATCHES/WARNINGS/ADVISORIES...
