Now Through Friday Night... Through Friday night, a modest shortwave trough exits the south central states and becomes a bit better defined while advancing across much of the southeastern states, and a central Canada upper trough meanwhile advances into the northeast states. A surface low develops in response to this pattern and brings a trailing cold front into the interior southeast states, but otherwise a light southerly flow prevails over the forecast area. Will have mostly dry conditions for tonight except for a slight chance for showers and storms over Wayne and Choctaw counties. For Friday, have gone with slight chance to chance probability of precipitation mostly west of I-65, then dry conditions prevail for Friday night. Lows tonight and Friday night range from the lower 60s inland to the mid 60s near the coast, and patchy late night fog is possible. Highs on Friday will be in the mid 80s except for lower 80s at the coast. A low risk of rip currents tonight and Friday will be followed by a moderate risk for Friday night. /29

Saturday Through Thursday... Northwesterly flow aloft will be in place at the start of the period as an upper-level ridge builds from Mexico into the central US. A weak shortwave, embedded within the flow aloft, appears to pass across the local area on Sunday. By Monday, the upper ridge begins to build eastward; its axis passing directly overhead Monday night into Tuesday. Flow aloft turns southwesterly by Wednesday and Thursday as the ridge moves into the western Atlantic. At the surface, high pressure over the northern US will quickly dive southeastward, reaching the Appalachians by Sunday night and the western Atlantic by Monday night. As it does so, it will help to send a very weak 'backdoor cold front' into the area from the northeast on Sunday. The front will quickly wash out by Monday as the high builds in across the southeast US.

For Saturday, expecting a continued persistence forecast from the near term period, with isolated to widely scattered showers and thunderstorms developing during the afternoon hours over interior portions of southeast Mississippi and southwest Alabama (mainly west of I-65). By Sunday, as the upper shortwave passes overhead and the frontal boundary moves in from the northeast, expecting another round of scattered showers/storms to develop along during the afternoon hours. As of right now, the best rain chances appear to remain focused along the front. We begin to dry out on Monday and especially into Tuesday and Wednesday as the upper ridge builds overhead. Rain chances return to the forecast by Thursday as the ridge moves off to the east. Highs will top out in the mid to upper 80s, with a few interior locations reaching the low 90s. Lows each night will be in the 60s. /96
