...Rainfall appears likely over the next several days...

The broad upper level ridge of high pressure that has been responsible for above average temperatures and below normal rainfall amounts as of late has moved away from the region. During this past weekend, it became compressed and centered itself over portions of the Central Plains and the Mid Mississippi River Valley. While in this location, a series of disturbances rode around its periphery. These disturbances travelled in an East to West manner across the Southeast United States and into the four state region, providing us with precipitation as well as widespread cloud cover and cooler temperatures.

As of Monday, this ridge moved westward and expanded itself over the western United States. This too will have a major impact on the pattern over the region. Whereas the flow was eastward during the weekend, the flow is now in more of a North/Northwesterly direction, allowing a surface cold front to approach the area from the north. This front will do two things, first, it will continue to keep temperatures cooler than the area has experienced in a while and secondly, it will continue to help focus rain chances across the area, as the front will likely stall across northern Louisiana.
