Valid 031200Z - 041200Z


Severe thunderstorms are not forecast across the contiguous United
States on Friday.

A powerful mid-level shortwave trough/speed max is forecast to move
through the base of a larger-scale trough and translate eastward
across the upper Ohio Valley and Mid-Atlantic states by late
afternoon Friday.  Upstream of this disturbance, a mid-level ridge
will amplify over the north-central U.S. as a lead impulse moves
into the Pacific Northwest states late Friday.  Offshore low-level
flow into the Gulf of Mexico will lead to tranquil conditions over a
large portion of the Lower 48 states.
