Valid 141300Z - 151200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not anticipated today.
...Synopsis...
An upper trough is expected to rapidly deepen over the northern
Rockies this afternoon, resulting in steep lapse rates, cold
temperatures aloft, and strong large-scale forcing over northwest
WY. Despite cold surface temperatures, at least isolated
thunderstorms are expected.
A developing low-level baroclinic zone over MN/WI will be the focus
for thunderstorm development tonight as the low-level jet
strengthens. Much of this activity will likely be associated with
freezing precip and heavy snowfall.
Finally, scattered showers and thunderstorms will affect much of
central/south FL, in a rather weakly sheared environment.
