A very mild southwesterly air flow has developed on the back side of high pressure over the southeastern states. The air is quite dry with the present trajectory coming out of the southern plains. It will remain mild overnight, and on St. Patrick's Day the temperature will top out around 63 degrees. If we happen to get more sunshine than is presently expected, temperatures could reach the upper 60's. The system is moisture starved, but with a cool front moving into the area in the evening there may be enough instability to cause some rumbles of thunder along with light rain showers in the afternoon and evening. After the cool front slips to the southeast the rain showers will come to an end before midnight. It will be partly cloudy and cooler on Friday. On Saturday a ridge of high pressure will nose it's way across the upper midwest with light northeasterly winds, plentiful sunshine, and a temperature in the low 50's. Sunday will start off mostly sunny, but it will cloud over in the afternoon with southeasterly winds developing in advance of a complex area of low pressure over the plains. There is a chance of some rain showers in the afternoon that may blossom into thunderstorms on Sunday night with plentiful moisture from the Gulf of Mexico over-running a warm front moving northward from the lower Mississippi River Valley into the Stateline area by 6 am on Monday morning. That storm system will then move off to the northeast, only to have another system follow right on it's heels by Tuesday morning. The net effect for the Stateline will be continuing chances of showers and thunderstorms off and on from Sunday night through late Tuesday. Colder air from Canada will follow in behind the departing storm system on Tuesday night, and rain could mix with wet snow overnight into the morning hours on Wednesday.
