Rain Chances on the Board

Overview
There is a LPS (Low Pressure System) North of the NE U.S and GLR (Great Lakes Region) with a front stretched South, over the Atlantic Ocean and across the SE U.S. There is also a developing LPS over the Southern Plains.
In the wake of this cold front a ridge of high pressure is building over the GLR and ORV (Ohio River Valley) through the GLR, Central Plains & ORV (Ohio River Valley).

In the tropics we are keeping an eye on newly formed Tropical Storm Dorian continued possible development.

Discussion
There is a broad ridge of high pressure that extends over the northern GoM (Gulf of Mexico). This ridge reaches up into Central Louisiana and is assisting in breaking down an approaching MCS (MesoScale Convective System) that is moving toward us from the North.
This MCS contained strong thunderstorms and heavy rainfall several hours ago. Through the morning hours we have been seeing this system decay as it runs into this ridge.
It looks as though the high will stick in there and continue to assist in the dissipation of his storm system. However, as the boundary continues to move South during peak heating, we could see an additional flare up during the afternoon and evening hours. So, rain chances will still be on the board and we are keeping the current forecast with just less than half of the viewing area receiving rainfall today.
After this piece of energy moves through our area, we will return to a period of an air mass that is dominated by high pressure. This will keep rain chances down to a slight chance through the end of the work week. The weekend will bring changes to the board.
Temps will be around the same as we have seen during the past couple of days as skies keep some clouds with the possibility of afternoon rain. If an area gets rain during peak heating a "Rain Cooling Action" will knock highs down for that area. Otherwise, temperatures will continue to rise and Heat Index values will climb to the 100-108 range.
Saturday & Sunday, rain chances come back up a bit and temps fall back to a seasonable range.

For the rest of the day,
Skies will remain partly to mostly cloudy with in & out cover. Temperatures will rise into the mid 90s and Feels Like temp will range between 100-105. There will be fair chance for scattered rain through the afternoon and evening as a piece of energy moves through the area.
Overnight, expect lows in the 70s with a muggy feel and lingering showers possible.

For the rest of the 7day planner
Rain chances will be up today. The end of the work week will bring lower chances, leading up to the weekend. The weekend will bring a chance for scattered rain, coupled with slightly cooler temps and a warming trend will start to pull those highs back up come Monday.

TODAY... Partly cloudy skies with in & out clouds and afternoon rain chances (30%). Highs near 96. W wind 5-15mph. 
Peak Heat index near 103.


WEDNESDAY NIGHT...A muggy feel with fair to partly cloudy skies. Lows 69-76. SW wind 2-10mph.
