A Cool/Wet Pattern
 
High pressure ("H") built into the western United States as a trough of low pressure ("L") deepened east of the Mississippi River in mid-July 2009. High pressure shifted to the west of Arkansas in July. This created a northwest wind flow aloft, which drove storm systems and fronts into the state from the Plains.
