Very warm and humid Wednesday with isolated afternoon storms possible

Today will still end up very warm and humid, but an area of high pressure (the "heat dome"), has shifted slightly to the north and will allow more moisture to slide into Texas from Louisiana. As a result, isolated thunderstorms are expected and a few brief, heavy downpours are possible. Otherwise, the story remains focused on daily highs near 100 and possible heat advisories by the end of the week.
