A sharp upper level trough, in combination with a cold fron,t is producing a long zone of rain and showers from the Colorado foothills, through the Midwest, into New England. This is the first of several bouts of rain that will affect the Midwest this week. The graphic from the NWS shows the expected average rainfall from Sunday morning through Friday morning. As can be seen, the heaviest amounts are expected over the western Midwest and into the Plains, areas hardest hit by our most recent drought.
The rainfall is sorely needed as drought conditions continue to expand as seen at the link here. Since no heavy rain is expected, the precipitation will just stabilize the dry conditions. The bouts of rain will result from the cold front initially moving southe, then moving back north as a warm front mid week and then a new cold front coming in from the Pacific for the end of the week. No hot and dry conditions this week like we have basically experienced the past two weeks.
For the Chicago metro area, a nice slow soaking rain for today Sunday. The rain will end in the evening with another nice Canadian high pressure system for Monday and Tuesday. The warm front and an upper air disturbance will be in the area Wednesday for a chance of showers and storms. Another chance of storms Thursday night into early Friday with the new cold front. Temperatures will bob around from jus the 60s today and Monday, into the low to mid 80s by Thursday, and then around 80 for Friday.
