Bill Murray: Summer still in charge as August heat takes hold in Alabama

Summertime is still in charge across Alabama as high pressure builds across the region sending the mercury upwards and the afternoon thunderstorms back to their corners for a while. There will still be a few each day, and they can pack a punch, but our days will be mostly sunny through midweek.

METEOROLOGICAL SETUP
A weakening mid-level disturbance (yesterday’s MCV) is sliding southeast while a stout ridge parks over the nation’s mid-section. For Alabama, that means slightly drier air aloft and northerly flow today, trimming storm coverage for many — greatest chances southeast. The ridge strengthens early week before retrograding west, allowing a weak eastern U.S. trough to nudge rain chances back up late week. Heat remains the main storyline.

FOR YOUR SATURDAY
Some morning fog is burning off across the state. Visibilities were less than 1/4 of a mile for the better part of the morning. Dense fog advisories were in effect through 9 a.m. Highs will be in the 90s for the most part with just isolated to widely scattered afternoon storms.

SUNDAY AND SUNDAY NIGHT
Hot, partly sunny, and seasonably stormy. Highs 91–95 with the higher heat index (100–105) south and west. Widely scattered afternoon/evening storms for central and north Alabama (20–30%), scattered to numerous from Montgomery to the Wiregrass (40–60%), where sea-breeze help arrives from the Florida Big Bend. Any storm can produce gusty winds and brief torrential rain. Tonight: easing storms, lows 72–75, patchy late-night valley fog where rain fell.

EARLY WEEK: HOTTER, DRIER FEEL: RIDGING RULES
Monday–Wednesday trend hotter with fewer storms. Highs low–mid 90s; heat indices flirt with 105°, especially Tuesday and Wednesday. Isolated to scattered p.m. storms (10–30%), highest east. Hydrate, take breaks, and look before you lock.

LATE WEEK: RAIN CHANCES TICK UP: RIDGE RETROGRADES…EASTERN TROUGH NUDGES IN
Thursday and Friday bring a notch lower temperatures (upper 80s to low 90s) and a notch higher storm coverage (30–50%) as moisture deepens and weak troughing edges in. Downpours will be brief but locally heavy; outdoor plans need a Plan B.

NEXT WEEKEND: TYPICAL AUGUST MIX: SEABREEZE AND SUN
Seasonable heat (upper 80s/low 90s), scattered afternoon storms (30–50%), and muggy nights in the 70s. No organized systems aimed at Alabama at this time.

VOODOO TERRITORY (WEEK TWO PEEK): PATTERN EVOLVES, NOT EXTREME
Guidance favors the core of the heat backing into the Southwest while a broader trough lingers over the East. For Alabama that suggests near-normal temps, daily storm chances and lower odds of prolonged extreme heat. Confidence is modest this far out.

SEVERE WEATHER OUTLOOK (SPC): NO ORGANIZED SEVERE RISK HERE
The Storm Prediction Center highlights a Slight Risk over South Dakota with strong storms in the northern Plains. For Alabama, only isolated strong pulse storms are expected — brief gusty winds and frequent lightning possible, mainly during the afternoon/evening. Can’t rule out a damaging downburst wind gust and rogue severe thunderstorm warning, so be alert.

TROPICAL WEATHER OUTLOOK: ERIN STAYS WELL EAST
Hurricane Erin is well east-northeast of the northern Leeward Islands and forecast to stay over the western Atlantic and east of the United States, but it will bring dangerous surf and a big rip current risk to the East Coast next week. It really rapidly intensified overnight and now has top winds of 145 mph. A weak low off the North Carolina coast has a low (10%) chance of development. No Gulf or U.S. impacts for Alabama and the Panhandle in the near term. We’ll keep watch, as always, through the season.

BEACH FORECAST: BEAUTIFUL BEACHES OF ALABAMA & NW FLORIDA: SUNNY STRETCH WITH LOW SURF
Water temperatures mid-80s to around 86°. Surf around 1 ft. Rip current risk: low along Alabama beaches (Dauphin Island–Orange Beach); low to moderate from Pensacola to Panama City to the Forgotten Coast (many beaches flying yellow flags). UV index extreme — reapply often. Isolated to scattered afternoon storms each day; mornings favored for the best beach time. Light onshore/sea-breeze winds most afternoons. Water temps are in the mid 80s generally.

WEATHER HISTORY: A WARNING BOUGHT WITH COURAGE
On this date in 1969, with Navy planes tied up in Project STORMFURY, NHC Director Robert Simpson asked the U.S. Air Force to investigate Hurricane Camille. An Air Weather Service C-130 found 905 mb and 160 mph winds — evidence that allowed forecasters to warn of unprecedented devastation along the Gulf Coast.
