12/27 – Rob’s “Gray/Gloomy with Heavy Rain” Forecast

The first batch of rain is out of the area with winds fairly brisk and gusty as some gusts above 40 mph were measured, leading to a few power outages. With sustained winds nearing 30 mph in a few areas,

a WIND ADVISORY has been issued for a few hours this morning.

In addition, lowering pressures and higher winds will cause some coastal flood issues along the Mississippi Gulf Coast this morning.

A break in the action is expected for the next few hours before rain begins to develop again late morning, ahead of the line moving in from the west. With plenty of moisture in place, heavy rainfall remains a concern today.

The northern part of the area is now in a MARGINAL risk of excessive rainfall with the rest of the area remaining in a slight risk.

A FLASH FLOOD WATCH remains in effect for the entire forecast area through early Friday morning. Rainfall amounts of 2-4 inches are now expected area wide with isolated higher amounts possible. A few areas of 5 inch plus rainfall cannot be ruled out at this time. In addition to the heavy rainfall threat, some of the storms could become severe with the main threat being strong winds and an isolated tornado. Rain chances remain high early Friday before tapering off some on Friday evening and into Friday night.

The big concern continues to be the larger scale pattern through the weekend as the frontal boundary will likely remain stalled out near the central Gulf coast. Bursts of showers and at times bands of thunderstorms with downpours are likely to occur over the weekend and possibly exasperate any flooding and rising river issues. Temperatures will remain above normal to the southeast of the meandering frontal boundary, but turning cooler behind the front by early next week.
