Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1155 PM CST Wed Feb 14 2018
Valid 151200Z - 161200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms will be possible across the Ohio Valley late
this afternoon into this evening.
...DISCUSSION...
West to southwest mid-level flow will remain across much of the
CONUS today. At the surface, a moist airmass will be in place across
the Gulf Coast region extending northward into the mid Mississippi
and Ohio Valleys. A cold front will advance southeastward across the
Great Lakes region and mid Mississippi Valley. Low-topped
thunderstorm development will be possible along or just ahead of the
front but instability should remain very weak. For this reason, a
severe threat is not expected. Elsewhere across the CONUS,
thunderstorm development is not forecast across through tonight.
