Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1126 PM CST Fri Feb 03 2017
Valid 041200Z - 051200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are unlikely across the contiguous United States for
today and tonight.
...Synopsis/Discussion...
A multi-stream, quasi-zonal-flow pattern with embedded speed maxima
will characterize the mid levels across a large part of the country,
while a shortwave trough continues advancing off the East Coast.
Forcing for ascent associated with these perturbations is not
forecast to phase with sufficient moisture/instability for
thunderstorm development. Surface troughing over portions of the
High Plains and North-Central States will encourage the gradual
northward spread of weakly modified Gulf moisture across parts of
the South-Central States. Very limited buoyancy, ample capping, and
the paucity of deep ascent should preclude thunderstorm development
in this initial moisture-return regime.
