SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1135 PM CST Sat Jan 02 2021 Valid 041200Z - 051200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few low-topped thunderstorms will be possible Monday across the coastal Pacific Northwest and into parts of northern California. ...Synopsis... Strong cooling aloft/height falls will occur through 00Z over WA, OR and northern CA as a shortwave trough moves ashore. Convergence near a cold front will be maximized along the OR and northern CA coastal areas, and this is where low-topped thunderstorms are most likely. Forecast soundings indicate MLCAPE around 100 J/kg eventually developing over southwest OR and coastal northern CA as lapse rates steepen with the rapid cooling aloft. Low-level winds will likely veer by this time, resulting in long hodographs. Gusty winds are possible with the heavier convection, but severe chances appear low at this time. Elsewhere, offshore surface winds will result in stable conditions over much of the central and eastern states with high pressure at the surface. ..Jewell.. 01/03/2021
