Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1200 PM CDT Fri Nov 03 2023

Valid 041200Z - 051200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Isolated thunderstorms appear possible across parts of the Pacific
Northwest and south Florida on Saturday.

....Synopsis and Discussion...
Another in a series of upper troughs will move eastward across the
Pacific Northwest on Saturday. Strong mid-level flow accompanying
this upper trough will overspread this region through the day, along
with cooling mid-level temperatures. As this occurs, modest
instability should develop along/near the WA/OR Coast into parts of
northwestern CA. Occasional lightning flashes may occur with
low-topped convection that develops across these areas as a surface
front progresses eastward. Additional isolated thunderstorms appear
possible Saturday afternoon across parts of interior WA/OR into ID
as large-scale ascent attendant to the upper trough spreads over
these areas. Limited low-level moisture and weak instability are
expected to preclude a threat for severe convection.

Across south FL, isolated thunderstorms appear possible through the
day as a weak mid-level shortwave trough moves slowly eastward over
the Gulf of Mexico and the FL Peninsula. Poor lapse rates and weak
instability should temper the updraft strength with any convection
that develops.
