Nicholas continues to weaken as it tracks to the east into southern Louisiana, producing heavy rain. In south Texas, we are seeing dry air moving in behind the storm which will keep us dry and hot the next couple days with plenty of sunshine.
High temperatures will reach the low to mid 90s Wednesday and Thursday with north to northeast winds at 8-15 mph. Heat indices will reach 100-105.
