Friday brings warm and mostly dry conditions before rain chances increase over the weekend. Scattered showers and thunderstorms are expected Saturday afternoon into Sunday but totals are generally less than 1/2", with rain gradually ending from west to east Sunday afternoon. Drier conditions return Monday before another round of showers and thunderstorms becomes possible Tuesday evening and overnight. Afternoon highs will remain in the upper 70s to middle 80s throughout the period.
Rain chances will increase across southeast Louisiana and southern Mississippi on Halloween as a disturbance moves through the region. Scattered to widespread showers and a few thunderstorms are expected Saturday into Sunday, with the heaviest rainfall favored Saturday evening and overnight. Rainfall totals of 0.25 to 1 inch are generally expected, with the greatest amounts currently favored along the Mississippi Gulf Coast. Those with outdoor Halloween plans should prepare for potentially wet conditions.
Another round of active weather could impact southeast Louisiana and southern Mississippi Tuesday night into Wednesday morning as a strong storm system and associated cold front move through the region. Showers and thunderstorms are expected, and strong winds throughout the atmosphere could support a few severe thunderstorms if sufficient instability develops. However, uncertainty remains regarding the timing, coverage, and overall severe weather potential, including the threat of damaging winds and tornadoes. Continue monitoring forecast updates as details become clearer over the coming days.
