lightning flashes remain possible over the Pacific Northwest region,
though severe storms are not expected. See previous discussion below
for more details.

.PREV DISCUSSION... /ISSUED 1117 AM CDT Sun Mar 10 2024/

...Synopsis...
A broad upper low over the eastern US is forecast to move slowly
eastward today as an associated cold front moves offshore across New
England and South FL. To the west, a weak Pacific upper trough will
move inland with ascent overspreading the Cascades and northern
Rockies. Transient ridging over the central US will keep much of the
country cool and stable with dry offshore flow.

Weak thunderstorms ongoing across southern New England should
gradually diminish through the day as the increasingly narrow warm
sector moves toward the coast. Across South FL, weak convergence
along the cold front and limited large-scale ascent should keep
thunderstorm coverage low. Thunderstorm chances should lessen this
afternoon as weak buoyancy is removed with the frontal passage.
Across the Northwest, mid-level cooling and steepening lapse rates
aloft may support isolated lightning flashes over portions of the
Pacific Coast, Cascades and northern Rockies. However, with low
storm coverage and marginal thermodynamics expected, severe weather
is not expected.
