Alabama 811 | Know What's Below.

Hot Afternoon; Low Humidity

| August 16, 2019 @ 3:47 pm

DRY AIR: Temperatures are generally between 90 and 97 degrees across Alabama this afternoon, but the air is very dry with dew points down in the 50s in many areas. At 2:30p CT the Shelby County Airport was up to 97 degrees, but the dew point was down to 51, making the relative humidity only 21 percent. Amazingly low for summer in Alabama. The sky is sunny, and there is no rain anywhere in the state. The sky will be clear tonight.

THE ALABAMA WEEKEND: No real change tomorrow; expect a sunny sky with a high in the 90s. Humidity levels will stay low for August. Then, on Sunday, showers and storms are possible over the southern half of the state as moisture levels begin to rise. North Alabama will remain dry with a high between 92 and 96 degrees.

NEXT WEEK: An upper trough will bring the chance of scattered showers and storms to the state Monday and Tuesday; global model data continues to suggest the best chance of getting wet will be over the southern half of Alabama. Confidence in the forecast over the latter half of the week is low due to model inconsistency, but we will mention the chance of “scattered, mostly afternoon and evening thunderstorms”… with the higher coverage Thursday and Friday. See the Weather Xtreme video for maps, graphics, and more details.

AIR QUALITY ALERT TOMORROW: A “code orange” air quality alert has been issued for the Birmingham metro again tomorrow (Jefferson/Shelby counties) due to ground level ozone. The general public is not likely to be affected, but children, active adults, and people with respiratory disease such as asthma, should limit prolonged outdoor exertion, especially during the afternoon hours.

ON THIS DATE IN 1969: Emerging into the Gulf of Mexico, Hurricane Camille underwent a period of rapid intensification and became a Category 5 hurricane it moved northward towards the Louisiana–Mississippi region. Despite weakening slightly the morning of 17 August, the hurricane quickly re-intensified back into a Category 5 hurricane before it made landfall a half-hour before midnight at Pass Christian, Mississippi. The actual maximum sustained winds of Hurricane Camille are not known as the hurricane destroyed all the wind-recording instruments in the landfall area. Re-analysis data found peak winds of 150 knots (roughly 175 mph) along the coast. A devastating storm tide of 24.6 feet occurred west of our area in Pass Christian. Camille is one of only FOUR Category 5 hurricanes ever to make landfall in the continental United States (Atlantic Basin) – the others being the 1935 Labor Day Hurricane, which impacted the Florida Keys; Hurricane Andrew in 1992, which impacted south Florida; and Hurricane Michael in 2018, which impacted the Florida panhandle.

ON THIS DATE IN 1992: One of the most destructive United States hurricanes of record started modestly as a tropical wave that emerged from the west coast of Africa on August 14. The wave spawned a tropical depression on August 16, which became Tropical Storm Andrew the next day.
