Hopefully this will bring much needed rain to east AL. The lack of rain over the last week has been nothing short of pathetic. Almost as pathetic as the local forecasts that called for it.
5-day chances remain at 40%.

Forecast: Potential tropical system threatens to drench already soggy Tampa Bay area
[National Hurricane Center]

Flood warnings have been extended for the Alafia River in Lithia and the Little Manatee River at Wimauma as the National Weather Service continues to monitor a broad area of low pressure that has a building chance of developing into a tropical system.
And with more rain expected the next few days, even more rivers could be at risk, forecasters said.
The area of low pressure is drifting in the northwest Caribbean and could develop tropical conditions while it travels into the Gulf of Mexico by the end of the week, according to the National Hurricane Center. Forecasters place the chance of development around 40 percent in the next five days.
But even if it did not develop into a tropical system, an already drenched region can expect even more showers and thunderstorms.

"At best, it will be spreading a lot of rain our way by the end of the week," said Paul Close, a meteorologist for the National Weather Service.. "Most of the rain will fall on Friday and Saturday, it’s possible to continue into Sunday."
Close said this weekend will be very cloudy with off-and-on rain that will be very heavy in some areas.
According to Close, the gulf waters are not warm enough for a low-pressure system to sustain tropical conditions. Chances for development will be higher later in the year when Gulf waters warm over the summer.
But, Close warns, flooding could be a significant problem this week.
"Flooding will be a problem in general, especially urban flooding and low-lying areas," Close said. "We’ve had two or three days last week where we had 2-3 inches of rain within a few hours that flooded roads. That could happen this weekend."
A flood warning remains in effect for the Alafia River until Wednesday night. Flood stage is 13 feet, but as of Monday night at 9 p.m., it had reached 14.2 feet and is expected to rise to 14.5 feet on Tuesday before subsiding Wednesday afternoon.
The Manatee River reached 11½ feet Monday night, a half-foot above flood stage.
EXTENDED FORECAST: The 10-day outlook for the Tampa Bay area
Over the next two days, the Tampa Bay area will see that familiar summertime rain pattern of scattered showers and thunderstorms firing up primarily in the afternoon, forecasters said.
Tuesday morning temperatures sit in the low 70s with a lot of high humidity. By the afternoon, temperatures will rise to around 86 with a 60 percent chance of rain.
High rain fall has caused some minor flooding in the area and caused four sinkholes to form at the Villages retirement community in Central Florida.
As the week grinds on, folks should plan their morning and evening commutes with rain in mind. Rain chances will be at 60 percent throughout the week, and Memorial Day weekend could be a washout, forecasters said.
730 PM Special Tropical Weather Outlook. Medium chance (40%) of development of a broad low pressure system is possible late this week over the central or eastern Gulf of Mexico. Locally heavy rainfall is the main threat across western Cuba & Florida during the next several days. pic.twitter.com/YOxqiGDPhf

In partial deference to the models, I'm currently still near a respectable 1 in 3 chance for a TD to form this week though now I'm thinking in the GOM if it occurs, which is quite high for that area in late May based on history, but still only near a 5% chance for a subsequent FL TS hit. So, I'm saying that IF a TD forms this week, there's about a 1 in 6 chance for that TD to hit FL as a TS before the month is out. That's how I get my 5% FL TS hit chance. I'm at a 10% chance for an actual TS hit anywhere along the US Gulf coast by the end of May.
Regardless, heavy rain in parts of the SE is currently the biggest threat assuming slow movement. For some areas, this system could be a blessing even if there is heavy rain (assuming no flooding in those areas).
