The polar jet stream (and associated conflict zone between cold, dry air masses from Canada and warm, moist air masses from the Gulf of Mexico) drops further southward into the United States - bringing more frequent periods of stormy weather, with rain, ice and snow, and much more variable temperatures, with rapid temperature rises and falls not uncommon. In the interior South, in cities like Raleigh, NC, Atlanta, Birmingham, AL, Nashville, TN and Jackson, average summer highs and lows are similar to coastal areas, while some areas of interior eastern and central Texas (i.e. This record was broken by the Mt.
