DISCUSSION.

SHORT TERM [This afternoon through Sunday morning].

Wx map shows weak surface high pressure ridge a little further north across the Carolinas to KS/OK/AR. This is keeping light and variable winds across the region. Radar showing scattered showers and thunderstorms across Southern Louisiana and Southeast Texas. Temperatures in the lower to mid 90s, with upper 90s across Central Louisiana. The exception of 80s in the areas that received the showers and thunderstorms.

to upper 80s now expected to rise into the lower/mid 90s by mid to late afternoon. Heat index values expected to rise in the 105-110 range once again. Heat Advisory continues through 7 PM. No other updates needed at this time.

For Friday and Saturday, the mid to upper ridge over the central U.S. will build further southeast over our region. Expecting diminished chances of showers and thunderstorms, but slightly higher temperatures in the mid to upper 90s both days. Heat index values will range between 107 and 113 both afternoon. Have extended the Heat Advisory for Friday afternoon, and likely for Saturday afternoon if these heat index values continue in the forecast.

DML

LONG TERM [Sunday through Wednesday] .

The extended period kicks off with the degraded remains of the elongated upper level ridge off to the NW and a low level ridge over the gulf waters. Sunday is expected to be the last day of temperatures in the upper 90's and PoPs under 60 percent. Heat indices will again fly right under advisory criteria.

Now for the rest of the extended forecast summed up in one word: Rain. PoPs will increase going into Monday as a frontal boundary moves south into the region. The front will become quasi stationary by Tuesday as it lingers along the gulf coast for the remainder of the extended period. Afternoon PoPs range anywhere between 50-90 percent with three day rainfall totals (Mon-Wed) reaching 2.5 inches in some areas. The silver lining of increased cloud cover and and higher rain chances are the slightly lower temperatures. Instead of upper 90s, afternoon temps will be in the upper 80s to lower 90s. There is no noticeable change in overnight temperatures, which will remain in the 70s.
