NWS Mobile, AL wrote its last area forecast discussion before the first event at Jun 28, 3:04 PM CST, 16 minutes earlier.
Area Forecast Discussion National Weather Service Mobile AL 404 PM CDT Sun Jun 28 2020 .NEAR TERM UPDATE /Now Through Monday/...After dry air and overall stronger net subsidence turned yesterdays forecast upside down, I refuse to let it bit me two days in a row. With upper level ridging the driving factor across the area; however, it is competing with a very weak shortwave noted at 300 mb. Current radar and satellite imagery shows an expansive agitated cumulus field with ongoing showers just north of the interstate 10 corridor. With the influence of the weak ascent and a rather moist and unstable environment, storms are expected to spread inland across the area. Despite there being suitable ingredients for wet microbursts, the lack of shear and overall subsidence should keep most storms below severe criteria this afternoon. A strong wind gusts cannot be ruled out especially if storms can get some vertical development as the afternoon goes on. Storms will quickly diminish this evening as the weak trough moves off to the east and the daytime heating weakens. Ridging continues into the day Monday leaving us with a more classic summertime pattern with storms beginning on the land breeze during the morning and then a second round of more robust storms initiating along the seabreeze and spreading inland through boundary interactions. As per usual for summertime, conditions will be semi-favorable for gusty winds and possibly a severe storm, but overall the threat will be very localized to the storms that develop some vertical depth. Storms will diminish between 8 to 10 pm as diurnal heating diminishes. Along with the chance for storms, it will 100% feel like summer. With the ridge over head, clouds will be hard to come by allowing for quick heating during the afternoon. Temperatures will likely reach the low 90s today and tomorrow with heat indices in the upper 90s to low 100s. With dewpoints in the mid to upper 70s and even some 80 degree dewpoints floating around there will be very little relief overnight. For instance, last night Brookley Field had a heat index over 90 degrees the whole night. BB/03 && .SHORT TERM /Monday night Through Wednesday night/...The upper high pressure area over the Gulf of Mexico will expand westward to include northern Mexico through the short term. A small upper ridge extending northward from the northeast gulf to the western Great Lakes region will breakdown into a zonal flow over the southeast conus as an upper level shortwave over Missouri lifts north-northeast over the lower midwest, and the large upper low pressure area over the northeast conus expands toward the southwest. Meanwhile, the local area remains on the western periphery of a surface high in the western Atlantic, which will maintain our general southwesterly to westerly low level wind flow. The isolated to scattered convection late Monday afternoon will dissipate by sunset with the loss of daytime heating. Due to influence of the upper ridge aloft, expect dry conditions Monday night through much of Tuesday morning. With the moist mainly zonal flow pattern aloft will become prevalent across the region on Tuesday, with precipitable water values remaining between 1.7-1.9 inches and weak impulses in the mid level flow traversing the area, scattered afternoon showers and thunderstorms are forecast due to decreasing stability. Again the convection late Tuesday afternoon will dissipate by sunset with dry conditions overnight. Scattered, mainly afternoon, showers and thunderstorms are expected again on Wednesday. A few of the stronger thunderstorms both days could have brief gusty strong winds. Daytime highs Tuesday and Wednesday will range from 88 to 94 degrees, and remain muggy. Expect heat indices up to 100° both days. Low temperatures will be a carbon copy each night with temperatures only falling into the low 70s inland with upper 70s at the beaches. Rip current risk remains LOW through the short term. /22 && .EXTENDED TERM /Thursday Through Sunday/...The overall change in the weather pattern across much of the conus will continue to evolve as the upper trough extending from Nova Scotia to the lower Appalachian Mountains continue to swing southeast over the western Pacific. However, a broader upper trough will remain in place east of the Mississippi River, and actually dig southward over the northeast Gulf of Mexico through the remainder of the week as the remnants of the omega high dissipates and a strong upper ridge builds northward over the northern Great Plains and south central Canada. There also remains the likelihood that a low/mid closed low pressure area will either move into the southeast region from the north or develop across the region on Friday. There still remains a lot of uncertainty with the position/movement and strength of this feature, and we will continue to monitor the situation as it will impact which areas have the best chance of receiving precipitation as it remains over the southeast states through the 4th of July weekend. The extended term still looks to be unsettled and wet with abundant deep layer moisture remaining in place with precipitable water values between 1.5 to 2 inches. With the large area of upper weakness persisting and a frontal boundary meandering across the forecast area, expect numerous showers and thunderstorms each afternoon through the extended, with mainly scattered coverage during the overnight and morning hours. Daytime highs will persistently be in the mid 80s to lower 90s, with overnight lows generally in the low to mid 70s, except upper 70s right along the beaches. /22 && .MARINE...Light onshore flow continues through Tuesday with occasionally moderate onshore flow across the nearshore waters and bays in the afternoon. Isolated showers and storms are possible each afternoon across the nearshore waters and bays associated with the sea breeze. Winds become more westerly by the middle of the week with increasing rain by Thursday and Friday. BB/03 && .MOB WATCHES/WARNINGS/ADVISORIES... AL...None. FL...None. MS...None.
