Watching closely where an area of high pressure will set up throughout the week. The periphery of the main high pressure is where rain chances will exist. Although not high chances (20-40%), we still will monitor closely as we go throughout the week to see trends in the forecast.
Hot temperatures continue with above average values expected. Rain chances will increase as we go later in the week. Not very high chances (20-40%), but any rain chances would favor northern and western Panhandles.
