The synoptic pattern changes slightly today as a upper-level disturbance will linger along the Mississippi Gulf Coast through the weekend. Scattered to numerous coverage of storms this afternoon will occur mainly due to decreasing stability. Any stronger storms that develop will contain strong, gusty winds and the potential for locally heavy rainfall due to the slow movement of storms. Heat indices will climb to 104-107 degrees across the region today. This is just shy of heat advisory criteria (108 degrees) but will continue to monitor.
By early next week the upper trough to the east will begin to build back west over Louisiana and eventually over the ARKLATEX region as well. A cold front will then begin to be pushed southeast by another cold front to the northwest over the upper Mississippi Valley, eventually moving over the northern Gulf coast through the day Tuesday.
High temperatures will be in the upper 80s to lower 90s on Friday due to higher cloud cover and rainfall, then temperatures will increase to generally be in the lower to mid-90s through the weekend. Highs will slightly decrease to be in the upper 80s to lower 90s once again by Tuesday. Low temperatures will mainly be in the lower to upper 70s through Sunday night, with areas right along the Louisiana coast near 80 degrees. Lows Monday and Tuesday nights will then be in the lower to mid-70s for most inland areas, with areas right along the Louisiana coast in the upper 70s; although, a few spots over far southwest Mississippi could see lows in the upper 60s.
