Day 2 Convective Outlook
NWS Storm Prediction Center Norman OK
1105 AM CST Mon Nov 29 2021

Valid 301200Z - 011200Z


The risk of thunderstorms appears negligible across the U.S. Tuesday
through Tuesday night.


A broad swath of northwesterly mid/upper level flow will stretch
from the Pacific Northwest through the eastern U.S. A series of
midlevel shortwave troughs will pivot northeast across New England
and the Canadian Maritimes while another embedded shortwave trough
tracks from the northern/central Plains to the Midwest by Wednesday
morning. Surface high pressure will persist over the Southeast,
though southeasterly low-level flow will allow for at least some
shallow moisture return across western portions of the Gulf Coast
vicinity. Onshore flow also will allow for increasing boundary-layer
moisture across western WA/OR. While some weak destabilization is
possible amid modest midlevel lapse rates, relatively warm midlevel
temperatures will preclude thunderstorm activity.
