Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0611 AM CST Wed Feb 09 2022
Valid 091300Z - 101200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
The risk for thunderstorms appears negligible across the U.S. today
through tonight.
...Synopsis...
The large-scale pattern of a deep midlevel low over the upper Great
Lakes and a midlevel high just off the Pacific northwest coast will
largely preclude any threat for thunderstorms across the CONUS. A
cold front will continue to move southeastward off the southeast FL
coast/Keys, and some weak elevated convection will be possible this
morning across south FL to the cool side of the front. However, any
appreciable threat for thunderstorms will remain offshore along the
surface wind shift. Otherwise, an embedded shortwave trough and
associated/weak surface trough will cross the OH Valley by this
evening. Though low-midlevel lapse rates will be rather steep (> 7
C/km) with daytime heating/mixing, low-level moisture will be quite
limited within the continental polar air mass and will be
insufficient for deep convection/lightning this afternoon/evening
across northern KY/southern OH.
