Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1248 AM CDT Sat Mar 24 2018

Valid 241200Z - 251200Z


Thunderstorms are possible today -- mainly across the Ohio Valley
and Mid South, and over portions of the western states.

Eastward progression of the upper flow field over the U.S. is
expected today as an upper low/trough just off the Pacific Northwest
coast at the start of the period moves gradually inland.  A
shorter-wavelength disturbance will cross the Midwest/Ohio Valley
region, eventually becoming absorbed into the larger-scale cyclonic
flow persisting over the Northeast through the period.

At the surface, low pressure initially over the Missouri vicinity is
forecast move east into the Mid South, weakening with time.
Meanwhile, gradual progression of a cold front is forecast over the
interior West, ahead of the advancing upper trough.

Showers and scattered thunderstorms can be expected over parts of
the West, as the aforementioned system progresses.  Farther east,
showers and storms are expected across the Mid Mississippi and Lower
to Middle Ohio Valley, and into the Mid South region, in conjunction
with the weakening surface low.  In all areas however, severe
weather is not expected.
