A Mild Week on the Way... Significant Rains Mid Week...

High pressure is sitting over New Jersey this evening. It is very large, and continues to dominate Stateline weather overnight. Skies will be clear to mostly clear this evening, but the southerly wind flow on the back side of the high will keep temperatures from dropping too much. The southerly winds will bring more moist air, and some clouds in from the southwest later tonight. The low temperature overnight will be in the middle 20's. Clouds will continue to increase, lower and thicken, on Monday, and there could be some very light rain showers or sprinkles on Monday. The high on Monday will be around 38 degrees, and the low on Monday night near 31 degrees. Stratus low clouds will shroud the area on Tuesday as the atmosphere continues to moisten up with a continued southerly air flow across the area. Temperatures will  moderate with a high in the low 40's.  Rain will spread across the area on Tuesday night as low pressure begins to develop over the Texas panhandle. The temperature overnight is expected to hold in the middle 30's.   Low pressure will be over southeastern Colorado by early Wednesday, and a warm front will be poised east-west across southern Illinois westward across northern Kansas. The low will intensify as it moves rapidly northeast on Wednesday. The track will take it well to the west of the Stateline so all of the precipitation with this system will be rain. It will be cloudy, rainy and mild on Wednesday with a high in the middle 40's. The warm front will push across northern Illinois on Wednesday night with more rain showers, and possibly even a thunderstorm. The low on Wednesday night will be near 40 degrees, but a cold front will sweep across the area on Thursday morning. Temperatures will reach the low 40's before brisk northwesterly winds cause the temperatures to drop slowly for most of the day. Canadian high pressure will bring colder air, and clearing skies to the area on Thursday night. The low will be near 23 degrees early Friday morning. Friday will be mostly sunny and colder with a high only around 30 degrees.
