Some Light Showers Overnight and Early Sunday

You may wonder why we had so much wind today... Well, the answer is the tight pressure gradient between an extremely intense area of low pressure (28.70"), over James Bay in Canada (the southward extension of Hudson Bay into extreme northeastern Ontario)... and high pressure sitting over Arkansas. Whenever there is a tight gradient, a large difference in barometric pressure between a high and a low, there will be strong winds, and we had them here today. The wind gusted up to 44 mph at the Rockford airport this afternoon. The wind has diminished tonight as the low draws slowly toward the north, and a new weaker low moves in our direction out of the northern Rockies. Showers have developed over Minnesota, and western parts of Wisconsin this evening, and they are moving toward the southeast. Skies will be mostly cloudy overnight with some  light showers  that could last off and on through 9 am on Sunday morning. Not more than a few hundredths of an inch are expected because the air is quite dry, and it will take some time to saturate the atmosphere down to the surface. The overnight low will be in the middle 40's. On Sunday skies will start out cloudy with that chance of morning showers, and then the skies will start to break up, becoming partly cloudy in the Rockford area, and mostly sunny in the afternoon in the Freeport area, with a high close to normal, right around 60 degrees.  It will be mostly clear and cooler on Sunday night under the influence of weak high pressure. On Monday it will be partly to mostly sunny with a high in the upper 50's.  On Tuesday it will become mostly cloudy as a southern stream system moves east across southern Missouri. It will be close enough to possibly produce some scattered light rain showers across the Stateline.  It will be quite cool with a high only in the low 50's. On Wednesday there could be some widely scattered light rain showers as the low moves across Kentucky, and the winds pick up from the north as a massive Canadian high pressure over Montana starts to take control of Stateline weather. The brisk winds straight out of Canada will continue through Thursday. Night-time lows will drop into the low 30's, but no widespread frost is expected until Thursday night when the winds finally dies down.
