Valid 231200z - 241200z
..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.
