A huge funnel of cold canadian air is pumping straight down the center of the country into South Mississippi. Today, strong winds have continued to sweep through the region. This allows the cool high of 56 to seem even colder, but tonight will continue to feel cold with temps dropping into the upper 30's. Although Sunday night will probably be the coldest night of the season with some Freezes watches issued across the state.
Our pattern will shift out of the cold air mass by Tuesday into more moisture flow from the S/SW. This will conclude with another LOW swinging through the country and providing showers for us on Thursday/Friday.
Overall, it seems the consecutive warm nights is an after thought of the warm 2009 season because we are settling into our typical fall season of cooler overnight lows and less humidity.
