Freezing Temps Again Tonight

It was cold across the Stateline on Friday night with areas of frost and freezing temperatures. The high temperature on Saturday was 47 degrees. That is the coldest high temperature recorded at the Rockford airport since April 20th last spring. Also, 47 degrees is the average daily high temperature for November 16th. So, it really did feel like a mid November day on Saturday. The cold weather will continue overnight with a FREEZE WARNING in effect again tonight from 2 am until 8 am on Sunday morning.  It could be a hard freeze if there is enough clearing late tonight. Lows are expected to be in the upper 20's. Sunday will be sunny to mostly sunny and continued cool. The afternoon high will be in the low 50's, and that's well below the average high of 67 degrees for this time of year.  The massive cold high will shift to Oklahoma with a ridge eastward to Kentucky by Sunday evening.  It will be mostly clear overnight, and still pretty cold with a low near 32 degrees.  The wind will become southwesterly overnight and increase to 15-25 mph on Monday warming temperatures back up into the low 60's under mostly sunny skies.  With the wind holding at 10 to 20 mph on Monday night temperatures will be milder with a low of 45 degrees.  It will be partly cloudy and mild on Tuesday.  The high temperatures will be in the low to middle 60's, and there is a slight chance of showers in the afternoon.  A new cold front will push across the area on Tuesday evening, and there could be some light rain showers with the passage of the front.  High pressure following in behind the front will drop temperatures in the Stateline with mid 50 degree highs expected on Wednesday under sunny skies. That high will move rapidly to the east, and the wind will become southwesterly again on Thursday nudging temperatures back into the low 60's under sunny skies.  Another dry cold front will move southeast through the area on Thursday night dropping the temperature back into the middle to upper 30's.  On Friday it will be sunny with a high in the middle 50's.  Then there appears to be a significant change in the weather pattern developing on Saturday.    A fairly substantial storm system may develop over northwest Kansas early in the morning.  This system has potential for producing some good rainfall amounts for the Stateline Saturday and Sunday.  It's way too early to make any estimates this far out, but the area is suffering from extreme drought conditions.  It would be good to get a couple of days with a good soaking rain.
