VERY HOT CONDITIONS TO START THE WORK WEEK
A HEAT ADVISORY has been issued for nearly the entire Central Alabama area for Monday starting at 12:00 pm and expires at 9:00 pm. The following counties are included in the advisory: Autauga, Barbour, Bibb, Blount, Bullock, Chilton, Coosa, Dallas, Elmore, Fayette, Greene, Hale, Jefferson, Lamar, Lee, Lowndes, Macon, Marengo, Marion, Montgomery, Perry, Pickens, Pike, Russell, Shelby, St. Clair, Sumter, Talladega, Tallapoosa, Tuscaloosa, Walker, and Winston.
A HEAT ADVISORY has also been issued for Monday starting at 1:00 pm and expires at 6:00 pm Monday evening for the following North Alabama counties: Colbert, Cullman, Franklin, Lauderdale, Lawrence, Limestone, Madison, Marshall, and Morgan.
Hot and humid conditions will continue through the day on Monday as daytime highs will range from 93 to 96 degrees across Central Alabama as heat index values will range from 105 to 109 degrees. There will be plenty of sunshine to start the day, but some clouds will build with the heating of the day. Much of the area will have a very, very small chance of an isolated afternoon shower or storm (less than 20%) with a little higher chance south of the I-85 corridor (20%-25%).
NEVER LEAVE CHILDREN, DISABLED ADULTS, OR PETS IN PARKED VEHICLES
Each year, dozens of children and untold numbers of pets left in parked vehicles die from hyperthermia, which occurs when the body absorbs more heat than it can handle. Hyperthermia can occur even on a mild day with temperatures in the 70s. Studies have shown that the temperature inside a parked vehicle can rapidly rise to a dangerous level for children, pets and even adults. Leaving the windows slightly open does not significantly decrease the heating rate. The younger the child the more severe the effects because their bodies have not developed the ability to efficiently regulate its internal temperature.
IT GETS EVEN HOTTER ON TUESDAY
The ridging stays with us for one more day for Tuesday and will leave us with a parting shot of very hot temperatures. We’ll have a good bit of sunshine to start the day but some convective clouds will build with the heating of the day. There is a very small chance of an isolated afternoon shower or two for the area, but nearly everyone will stay dry. Highs will be in the mid to upper 90s across the area, and with dewpoints in the mid-70s, heat index values may top out close to or just over 110 degrees. The heat advisory will likely be extended over into Tuesday and possibly expanded to cover all of Central Alabama, and an excessive heat warning may be needed for the southwestern parts of the area.
A QUICK WEATHER TIDBIT
While reaching 100 degrees in Birmingham looks unlikely at this point, it has been quite a while since the Magic City topped the century mark. June 26, 2016, was the last time the city of Birmingham reached 100 degrees for the daytime high.
A BETTER CHANCE OF RAIN ARRIVES ON “HUMP DAY”
The good news is that the ridge breaks down across the area on Wednesday and will allow a trough to work into the area which will bring a surface boundary with it. Scattered to numerous showers and thunderstorms will be likely across all of Central Alabama with most of the activity occurring during the afternoon and evening hours. The cloud cover and rain should keep much of the area out of a heat advisory, but afternoon highs will still reach the upper 80s to the lower 90s.
The boundary will stall out somewhere over the southern portions of the area on Thursday which will keep an increased risk of scattered to numerous showers and thunderstorms over the southern and southeastern parts of Central Alabama. For the rest of the area, we’ll only have a small chance of isolated to scattered mainly afternoon showers and storms. Highs will be in the upper 80s to the lower 90s.
FRIDAY & THE WEEKEND
The boundary will continue to hang out over the southern portions of the area throughout the end of the week and the weekend, which will keep an increased risk of scattered showers and thunderstorms over the southern and southeastern parts of Central Alabama through Saturday, with s small chance of isolated to scattered showers and storms for the rest of the area. At this point, Sunday is trending a little drier with only a chance of a few isolated to scattered afternoon showers and storms possible. Highs on each day will be in the upper 80s to the lower 90s.
The Atlantic Basin is free and clear of any tropical systems and no new tropical disturbances are expected to form within the next five days.
