Another chance for Severe Weather by mid-week...

It is definitely Spring time across the four state region, with high levels of pollen, flowers blooming, afternoon temperatures warming into the 70s/80s and also Severe Weather. A strong storm system moved through on April 10th-11th bringing hail, damaging winds and heavy rainfall with it. Click here to see storm reports for that event or here to see rainfall totals. Well, it appears once again that the area will have at least the chance for severe weather by the middle part of the upcoming week. 
 (Click any of the images for a larger version)
Above: A slight risk of severe weather is in plcae just to the northwest of the area on Tuesday, April 16th. (Image courtesy of the Storm Prediction Center) Above: A look at the severe weather risk area for Wednesday, April 17th. (Image courtesy of the Storm Prediction Center)

A stalled cold front will be situated just north of the area by Monday and as an upper level storm system approaches from the west, it will act as a focusing mechanism for thunderstorms across central and southern portions of the country. A series of surface low pressure systems will ride along this frontal boundary, aiding in the development of thunderstorms. The front should finally push southward across the area late Wednesday into Thursday, this appears to be when the four state region has the best chance for thunderstorms and possibly severe weather. Some rainfall will likely linger through the day on Thursday, before the storm system fully exits the area that night.

Above: On Tuesday morning, notice the stalled front that extends from the Texas panhandle to the Great Lakes Region. (Image courtesy of the Weather Prediction Center) Above: By Thursday morning, the front is moving across the area. There will likely be a line of thunderstorms moving through late Wednesday through Thursday. (Image courtesy of the Weather Prediction Center)
