Likely Chance For Rain

Overview
Today, a ridge of High Pressure has weakened and exposed our area to a rich plume of moisture extending north, from the gulf coast. A ridge of high pressure is stretched over much of the eastern half of the nation providing mostly sunny skies and warming temperatures for many. In the Central Plains, Low Pressure System is continuing to develop.

In the Tropics, eyes are fixed on three different areas of interest in the Atlantic Basin, to include Tropical Storms Isaac & now fizzling, post tropical cyclone Joyce.

Discussion
Today, a ridge of high pressure is breaking down and moving toward the East. In lieu of this system,  we will see rain chances sky-rocket as a rich plume of moisture moves over our area. This plume of moisture is providing our state with needed instability for a lot of scattered showers and thunderstorm activity. This plume of moisture and high rain chances will remain in place through most of the weekend. Rain chances will begin to taper off later on Sunday.
  
For the rest of the day
Expect partly to mostly cloudy skies with widely scattered showers and thunderstorms throughout the area totaling 70% coverage today. This means that around three quarters of the viewing area will see some of this much needed rainfall. Winds will be moderate and variable (stronger near storms). Expect highs to climb into the upper 80's and lower 90's with higher humidity values and the return of the Heat Index. H.I. Values will be in the mid to upper 90's.
 
For the rest of the 7day planner
Elevated rain chances will stay strong through the weekend as this plume of moisture remains anchored over our State. The beginning of the work week will bring with it, gradually clearing skies, a warming trend and lower rain chances. Humidity values will remain moderate to high, putting Heat Indices in the 100-105 range.
T.S. Isaac is currently expected to make landfall on the Alabama Gulf Coast on Wednesday. Everyone needs to keep an eye on this storm as it enters the Gulf of Mexico late this weekend. Model guidance is divergent at that point and there is a broad scope of outcomes that this storm could have.

TODAY...Patchy early fog, otherwise, partly to mostly cloudy with scattered (60%) showers and thunderstorms. Highs 86-92. Variable wind, strong near storms.

FRIDAY NIGHT...Partly to mostly cloudy skies with a few showers and thunderstorms lingering. Lows 67-74. S/SE wind 3-9 mph.
