..no severe thunderstorm areas forecast... 


... 
isolated showers and storms are possible over portions of the 
Southern Plains states northeastward into the middle Mississippi 
River valley. A few storms may form over South Florida and perhaps 
near coastal New England. 


... 
A vertically-stacked area of low pressure off the northeast will 
move slowly northeastward as an upstream disturbance moves east-southeastward across parts 
of the Midwest. Several weak features embedded in fast middle-level 
flow will move across the Pacific northwest states into southern BC/Alberta. In 
the low levels...a residual and weakening front over Kansas/OK northeastward into 
Iowa will serve as a focus for isolated shower/thunderstorms 
early...before rising heights occur over the central states and limit 
shower/storm development from OK northeastward into the middle MS River Valley. 
The severe storm threat will likely be minimal on Thursday.
