DISCUSSION

Issued at 100 PM CDT Fri Jul 3 2026

03.12Z upper air maps continue to show a well defined low to mid level ridge of high pressure axis centered from the TN/OH River Valleys to the Mid-Atlantic. The local area is however on the southern periphery of this ridge where there is a path for mid level impulses caught up in the easterlies to make west northwest passage across the local area in the near-term which would provide a contribution to ascent as instability increases through the afternoon. An assessment of deep layer moisture shows areas primarily east of I-65 in lower PWAT values (ranging 1.3 to 1.5") while areas west of I-65 reflect better moisture profiles (PWAT's 1.6 to 1.8"). Surface wind field is very weak and highly variable in direction. Deep layer shear is non-existent. Appears the better chances of afternoon showers and storms would be across western portions of the Gulf coast, up across southeast MS focused along a weakly defined surface trof/sea-breeze. At this time, the risk of severe weather is low with a general storm outlook by the Storm Prediction Center (SPC) but can't rule out a strong storm here and there with brief strong wind gusts, frequent lightning, and locally heavy, short duration rainfall. The upper ridge to our north begins to weaken heading into the 4th of July Holiday weekend while at the same time shifting eastward to off the southeast U.S coast. There are indications that a mid-level trof/weakness in the height field sets up over the Lower MS River Valley through the course of the day Saturday and continues in place Sunday. This pattern looks to hold at least into the first half of next week. This suggests a transition to a more unsettled weather pattern with rain chances trending up as deep layer moisture shows recovery, reaching 1.9-2.1" by Sunday which looks to persist into next week. Saturday, forecasters anticipate a typical summertime convective mode with isolated to perhaps scattered showers and thunderstorms developing mostly south of U.S. Hwy 84, and focused along the sea breeze and resultant outflow boundaries. Sunday through Friday, a summertime diurnal pattern in rain chances with the higher PoPs looking to be evolving over the land areas each day, lowering at night. The better PoPs flipping to coastal waters at night.

Little change in daily highs/lows. 4th of July weekend highs range 91 to 96 interior, 89 to 93 coast. Going into next week, highs look to be tempered somewhat by the better rain chances, in the lower half of the 90's. Low temperatures through the period 73 to 77 interior. Much more muggy across the immediate coast/beaches with lows ranging 78 to perhaps around 81 in spots. Heat index values continue to be just below Heat Advisory threshold of 108-112, with maximum values of 100-107 for much of the area through early next week. As a more dominant southwesterly low level flow sets up each day, the increase in surface based moisture/dewpoints may put heat indices above Heat Advisory criteria at some point middle to late next week. /10

AVIATION

(00Z TAFS) Issued at 618 PM CDT Fri Jul 3 2026

VFR flight category prevails across the region through Saturday. Winds will become light and variable this evening after sunset, becoming southerly at 5 to 10 knots in the wake of a sea breeze boundary during the afternoon hours Saturday. Isolated showers and storms may temporarily reduce flight category at times during the afternoon Saturday. MM/25

MARINE

Issued at 100 PM CDT Fri Jul 3 2026

No impacts expected other than locally higher winds, waves and seas possible near thunderstorms. May see some waterspout activity during late night/morning shower and storm activity especially near the coast and area bays/sounds. /10
