SPC AC 301906
Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0106 PM CST Thu Jan 30 2025
Valid 011200Z - 021200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Thunderstorm potential across the United States appears low on
Saturday.
...Synopsis...
A low-amplitude, mostly zonal upper flow regime will emerge across
the CONUS on Saturday. A baroclinic zone will weaken, while a
surface front dissipates over the western Atlantic and FL Peninsula.
A few showers are possible over the FL Peninsula, especially near
the east coast as this occurs, but thunderstorm activity should be
limited due to poor thermodynamics, and weakening ascent and
vertical shear.
Moist, onshore flow will stream over the Pacific Northwest and
northern Rockies as a surface cold front develops east across the
region. Showers/low-topped convection with a couple of lightning
flashes may occur near coastal WA/OR into the northern Rockies given
cold midlevel temperatures and steep lapse rates. However, coverage
is expected to be less than 10 percent.
