Mostly Dry Weather For Alabama Through Friday; Watching The Gulf

| June 15, 2021 @ 5:54 am

LOWER HUMIDITY: Drier air continues to advance into Alabama this morning, and for the northern 2/3 of the state today will be mostly sunny and not as humid as recent days thanks to the lower dew points. We expect a high this afternoon in the upper 80s. A few scattered storms will form this afternoon over the far southern part of the state, where SPC has defined a low end, “marginal risk” (level 1/5) south of a line from Chatom to Andalusia to Dothan.

Dry weather will continue across the state tomorrow and Thursday with pleasant mornings… cooler pockets will drop into the mid to upper 50s during the early morning hours. Highs will be in the 85-89 degree range… right at seasonal averages for mid-June.

FRIDAY AND THE WEEKEND: Our weather will all depend on the behavior of a tropical low in the Gulf of Mexico. Rain is possible Friday over the southern half of the state, and we will forecast a good chance of occasional rain and possibly a few thunderstorms statewide Saturday and Sunday. Tropical systems like this in June can be very efficient rain producers, and there is potential for an axis of heavy for some part of the state, especially South Alabama. But, until the system actually becomes better organized, confidence in details (rain placement, timing, etc) remains low.

WPC is suggesting parts of South Alabama could see over 5 inches of rain Friday through Sunday… but again we stress this forecast could change.

Highs over the weekend will be generally in the 80s, although some places could hold in the 70s, especially Saturday with clouds and rain.

NEXT WEEK: The tropical system should be out of here by Monday, but a cold front could trigger a few showers late in the day or Monday night. Global model suggests drier could drop into North/Central Alabama by Tuesday and the mid-week period… See the Weather Xtreme video for maps, graphics, and more details.

TROPICS: Tropical Storm Bill is in the Atlantic well east of the upper U.S. Atlantic coast with winds of 50 mph. It becomes post-tropical late tonight as it gains latitude.

In the far eastern Atlantic, a tropical wave located several hundred miles south of the Cabo Verde Islands is producing a large area of cloudiness and disorganized showers. Any development of this system should be slow to occur during the next few days. Thereafter, a combination of dry air aloft and strong upper-level winds will limit chances of formation while the wave moves over the central tropical Atlantic.

For those in the Southeast U.S., the system to watch is in the Southwest Gulf of Mexico, where a tropical depression is expected to form within the next 72 hours. The main impact from this system will be heavy rain and rip currents for the central Gulf Coast Friday and Saturday; it won’t become a hurricane, and possibly won’t even reach tropical storm strength.

ON THIS DATE IN 1991: The second largest volcanic eruption of the 20th Century began as Mt. Pinatubo injected 15 to 30 million tons of sulfur dioxide 100,000 feet into the atmosphere. 343 people were killed in the Philippines as a result of the eruptions, and 200,000 were left homeless. Material from the explosion would spread around the globe, leading to climate changes worldwide as the sun’s energy was blocked out and global temperatures cooled by as much as one degree Fahrenheit. 1992 was globally one of the coldest since the 1970s.
