Midwest Pattern Update For Oct 7-14th

An upper level low situated over the Great Lakes on Wednesday will generally keep showers across the area thru the day on wednesday across the great lakes region and into ohio. By thursday , low pressure will be coming out of the Rockies region following along a stationary boundary. This low pressure area should generally track off to the northeast and as it does so will pull a cold front thru the region. Heavy rain is possible with this S/W and attending cold front across the ohio valley region and parts of the midwest from thursday thru friday. The cold front should clear the region by saturday. There after another S/W looks to come out of the rockies in the later part of the weekend while at the same time a developing low pressure will be forming in the southeast. These two S/Ws could bring more rainfall into  the Great Lakes region in the sunday to tuesday time frame. 

Probably the biggest weather story though will be the colder air across the  region behind each of the cold fronts. Early in the period temperatures look to be in the 40s and the 50s . By the start of the weekend across the northern areas & western areas of the midwest high temperatures will be dropping into the 30s and perhaps even some 20s across the region while further to the west 40s and 50s . Out ahead of the cold front temperatures on Friday across Ohio could get into the 60s. Once the cold front moves thru Ohio ..temperatures across the midwest will generally be in the 30s to the 50s. 

So the main story of the week will be the cold air that will be coming in across the region.
