Isaac Won’t Go Away

THIS AFTERNOON: A rather quiet day in the weather office for the northern half of Alabama; showers are basically a no-show so far. To the north, we are watching strong to severe storms over parts of North Mississippi, West Tennessee, and Northeast Arkansas; some of those could move into extreme Northwest Alabama tonight, and the Storm Prediction Center maintains a “slight risk” of severe weather around Muscle Shoals for this possibility. But, these storms will die down once the sun goes down, and most of North-Central Alabama will be dry tonight.

Temperatures are generally in the mid to upper 80s at mid-afternoon.

TOMORROW/FRIDAY: Not much change around here on the next two days; partly sunny, humid days will continue with only widely scattered afternoon and evening showers and storms. Heat levels will creep up a bit with a high near 90 on both days.

OUR WEEKEND: Saturday still looks relatively wet as a cold front slices into the state; showers and storms are likely with the potential for a heavy downpour or two. It won’t rain all day, but it could rain at any time during the day. And, the amount of rain will depends on the amount of tropical moisture aimed at Alabama from a system in the Gulf that has some potential to be a tropical depression or storm, but at this point most models take that deeper moisture toward the northern half of the Florida Peninsula. At this point we expect rain amounts on Saturday to be 1/2 to one inch, but that could change depending on the tropics.

BREATH OF FRESH AIR: A nice surge of cooler and drier continental air will blow into Alabama on Sunday. We will struggle to reach the 80 degree mark with a fresh north breeze along with a good supply of sunshine. And, there is a very good chance we will reach the cool 50s by daybreak Monday, and probably Tuesday as well.

The first half of next week looks rain-free with sunny pleasant days and clear cool nights. It will be our longest dry period in several weeks.

ISAAC BECOMES NADINE? While former Hurricane Isaac was sliced and diced by strong westerly winds aloft after landfall, part of the remnant circulation is on the Gulf Coast near Pensacola this afternoon. The surface low is drifting to the south/southwest, and there is some chance it could become better organized in the northern Gulf tomorrow and Friday. Should this become a tropical storm, it would get a new name since it is just a portion of Isaac, and the name would be Nadine.

Most computer models push the deeper moisture with this feature toward the northern half of the Florida Peninsula, with no direct impact on Alabama.

LESLIE: This system in the Atlantic reached hurricane status earlier today, and it has potential to become a major hurricane by the weekend. It will be dangerously close to the island of Bermuda Saturday night or early Sunday, and then it will be a threat to Newfoundland early next week. But, on impact on the U.S. East Coast other that rough surf and swells.

MICHAEL: This system should become a hurricane soon, it is southeast of Leslie in the open Atlantic and is not expected to impact any land area.
