THURSDAY: With an open flow off the Gulf of Mexico and subtle triggers, expect variably cloudy skies with a general scattering of storms to develop through the afternoon hours. Expect highs in the 80s to near 90. Similar to recent days, storms will have a little staying power past sunset before tapering around midnight. Lows will drop into the lower 70s.

FRIDAY: More of the same expected to round out the work week across central and southwest Mississippi. While the mornings may start off with a mix of sun and clouds, the afternoon heating will percolate scattered showers and storms that will last through early evening before diminishing. Highs will top out in the 80s to near 90; lows will be in the lower to middle 70s.

EXTENDED FORECAST: The deep tropical moisture hangs around and stays stagnant, thanks to the open flow off the Gulf. This will keep opportunities for showers and storms in the forecast daily along with a mix of clouds and sun. Expect highs in the upper 80s and lower 90s; lower to middle 90s return by Independence Day and into next week.

TALKIN’ TROPICS: Potential TC #2 continues its far southern trek into the Caribbean over the next few days. Strengthening is expected as it moves westward toward Costa Rica and Nicaragua by Friday. Another wave trekking behind it will has a lower chance to develop into its wake, but will bring squalls to the northern Windward Islands. On the tail end of a stalled boundary in the Gulf of Mexico, a non-tropical low could yield squally weather at times in SE Texas. That circulation could help spark scattered downpours around the Gulf South as it drifts back north over land.
