Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
1130 PM CST Mon Jan 03 2022
Valid 041200Z - 051200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated thunderstorms are expected in portions of the Pacific
Northwest today.
...Synopsis...
A broad upper trough will overspread much of the CONUS today, with a
strong northwesterly upper-level jet extending from the Pacific
Northwest to the central Plains. A weak shortwave impulse will move
onshore the WA/OR coast during the afternoon/evening in tandem with
a surface low. Steep lapse rates through around 650 mb and cold
temperatures beneath low equilibrium levels could support a few
lightning flashes. Thunderstorms are not expected across the rest of
the CONUS today/tonight.
