Clouds, Clouds, and More Clouds

High pressure cannot even clear out the clouds.  An area of high pressure will move from the northern plains tonight, across Wisconsin on Easter Sunday, and then off to the east.  It will pass close enough by to the north that it would ordinarily produce a nice sunny day for us on Sunday, but it is weak, and it is being over-ridden by moisture moving northeast over and above a quasi-stationary front stretching southwest to northeast from the southern plains of Oklahoma, across Missouri, southern Illinois, central Indiana into central Ohio.  The moisture is producing widespread cloud cover, and a little bit of light rain and sprinkles into the southern portions of the Stateline tonight.  Some of those sprinkles could edge as far north as the Rockford area, but very little rainfall is expected, and it should be over by morning.  Easter Sunday will not be quite as nice as you would like to see with mostly cloudy conditions along with temperatures reaching the upper 50's during the afternoon.  As low pressure becomes a little better organized by Sunday night, some light rain showers could develop northward into the Stateline once again.  A better flow of moisture will feed northward as the low spins itself up over Missouri later on Monday that will push the front a little northward and generate more widespread rains and even some thunderstorms.  Showers will be continuing into Monday night, along with some rumbles of thunder.  That system will spin off to the northeast across Wisconsin by early Wednesday, but there may still be some scattered showers lagging behind as another disturbance develops over Arkansas.  That system will combine with the original system over northern lower Michigan, and continue to intensify by early Thursday morning.  It will be windy as the system moves though and passes off to the northeast.  Scattered showers will remain in the picture through Thursday.  It looks like we may finally get a break with some decent weather possible with mostly sunny skies and warmer temperatures on Friday.  The high may reach the middle 60's.  Rain may move back in again with the next system on Saturday.
