TROPICAL STORM DON
TS Don is tracking west-northwest at a forward speed of 10mph. The center of TS Don should cross the central Gulf of Mexico today, approach the Texas coast on Friday and reach the Texas coast late Friday night or Saturday. Maximum sustained winds are near 45mph with higher gusts. Gradual strengthening is forecast during the next 36 hours; however Don is forecast to remain a tropical storm. There will be minimal local impacts to southwest Louisiana to include a small rise in tides and slightly enhanced rain chances.
SOUTHEAST LOUISIANA: Today there is an 80 percent chance for daytime thunderstorms decreasing to 20 percent in the evening. Saturday through Monday will see a 20-30 percent chance of scattered and isolated thunderstorms throughout the day each day.
Temperatures: Today: 90/77, Friday: 95/77, Saturday: 95/76, Sunday: 93/76, Monday: 95/75.
HAZARDOUS WEATHER: Numerous showers and thunderstorms will occur across the area today as deep tropical moisture continues over the region and Tropical Storm Don moves westward across the central Gulf of Mexico. Over the coastal waters, southeast winds will increase to 15 to 20 mph with seas building to 4 to 6 feet through tonight. In addition, waterspouts will remain a threat mainly through early afternoon today. Since storm motion will bring showers and thunderstorms on shore today, any waterspouts that occur will have a high potential of moving inland before dissipating. Waterspout potential will begin to ease during the afternoon.
Tropical Storm Don is expected to make landfall along the lower Texas coast shortly after midnight Saturday morning. As Don moves farther west, winds and seas will subside across the coastal waters for the weekend. Showers and thunderstorms will decrease in coverage over the weekend allowing daytime high temperatures to rise into the mid 90s across most areas. Heat index values will likely reach or exceed 105 degrees. A return to scattered daytime thunderstorms is expected during the early part of next week.
SOUTHWEST LOUISIANA: Today and Friday has a 50 percent chance of thunderstorms with a decrease to 30 percent in the evenings. Saturday through Monday will see a 20-30 percent slight chance for thunderstorms throughout the day each day.
Temperatures: Today: 90/78, Friday: 90/77, Saturday: 91/76, Sunday: 95/77, Monday: 95/77.
HAZARDOUS WEATHER: Scattered showers and thunderstorms can be expected again today through the evening hours, with the highest chances continuing over lower Acadiana. Like yesterday, a few of the storms could produce wind gusts of 40 to 50 mph, frequent lightning and heavy rains of 1 to 2 inches over a short period of time, which will quickly result in ponding of water on roadways.
Lingering moisture across the northern Gulf coupled with the northern fringes of Tropical Storm Don will continue the chance of showers and thunderstorms Friday into Saturday. Tropical Storm Don is expected to make landfall across the lower Texas coast early Saturday morning. As the system moves further inland across the Rio Grande Valley, the chances of showers and thunderstorms will decrease from east to west during the day Saturday. For the remainder of the weekend through Wednesday of next week, the mid to upper level high will be the dominate weather feature.
CENTRAL LOUISIANA: Today and Friday has a 50 percent chance of thunderstorms decreasing to 30 percent in the evenings. Saturday through Monday will see a 20-30 percent slight chance for thunderstorms throughout the day each day
Temperatures: Today: 91/76, Friday: 93/75, Saturday: 93/75, Sunday: 96/76, Monday: 96/76.

Temperatures: Today: 91/76, Friday: 93/75, Saturday: 93/75, Sunday: 96/76, Monday: 96/76.
HAZARDOUS WEATHER: Scattered showers and thunderstorms will be possible today across much of the four state region, as a series of upper level disturbances drift north into the region from south Louisiana. Any thunderstorm that develops will have the potential to produce strong and gusty winds, brief heavy rainfall and frequent lightning. The storms should diminish this evening with the loss of daytime heating. However, additional shower and thunderstorm redevelopment will be possible overnight as this disturbance lingers over the area.
Brief heavy rainfall, strong gusty winds and frequent lightning will be possible from the stronger storms this weekend and into early next week. Very hot and humid conditions will return to much of the region this weekend and early next week, as the upper level ridge of high pressure begins to build back east across the plains and Mississippi Valley.
