250am CDT Thu August 22 2019

Wx map shows surface high pressure ridge across the Northern Gulf, yielding a light south to southeast flow across the region. Temperatures in the mid to upper 70s, with dewpoints a degree of two lower.

Radar showing isolated nocturnal showers across the coastal waters moving inland across the coastal parishes and counties. By late morning into the afternoon, increased chances of showers and thunderstorms can be expected inland, with slightly higher chances for South Central Louisiana. Lower chances for inland SE TX with slightly higher temperatures for the afternoon. Afternoon highs near 90 along and south of I-10, with lower 90s across Inland SE TX/C LA, and heat index values reaching 100-105 expected.

Increased moisture and lift associated with a tropical wave (across the Central Gulf this morning) will be moving across the Northwest Gulf into our coastal waters, and further inland for the remainder of the day Friday into Saturday. Rainfall could be quite generous along and south of I-10 corridor into the coastal waters. Aloft, a shortwave moving across TX into LA during this period will provide sufficient lift. Still too early to pinpoint where the excessive rain will occur.

Slightly lower chances of showers and thunderstorms can be expected by Sunday into next week. Abundant moisture and daytime heating will keep the repetitive pattern of late morning/afternoon showers and thunderstorms through at least Wednesday.
