...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorms are unlikely today.
...Synopsis...
Several shortwave troughs are forecast to progress eastward today
within the cyclonic flow aloft covering much of the central and
eastern CONUS. At the same time, upper ridging will move eastward
across the western CONUS to the Intermountain West and a strong
shortwave trough will move across the Pacific Northwest. This
evolution will lead to a modestly amplified trough/ridge/trough
pattern over the CONUS by early tomorrow.
Even with this relatively progressive pattern, the extensive and
cold airmass in place over much of the CONUS will promote offshore
trajectories and cold/stable sensible weather. Strongest convection
today is anticipated with a frontal band attendant to the Pacific
Northwest shortwave trough. However, this convection will still be
too shallow to produce lightning.
