Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1111 PM CST Tue Jan 30 2018
Valid 311200Z - 011200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorm potential is very low across the contiguous United
States Wednesday.
...Discussion...
Semi-persistent large-scale northwesterly flow will continue across
the CONUS Wednesday. Resultant seasonally low precipitable water
values, and the lack of meaningful instability, will preclude deep
convection capable of generating lightning.
