Day 2 Convective Outlook  
NWS Storm Prediction Center Norman OK
1228 AM CDT Mon Oct 26 2020

Valid 271200Z - 281200Z


Severe thunderstorms are not currently forecast across the
contiguous United States on Tuesday.

A mid-level low will move from southeast AZ eastward across southern
NM during the period and remain displaced to the south of the
primary belt of westerlies located over the northern tier of states.
Tropical cyclone Zeta is forecast to move from the Yucatan Peninsula
north-northwestward into the central Gulf of Mexico south of
southern LA.  In the low levels, an arctic front will move little
from south TX north-northeastward along the TX coast and into the
lower MS Valley.  Weak elevated instability and large-scale forcing
will promote episodic, elevated, and widely spaced thunderstorms
across the southern Great Plains.  Isolated thunderstorms are also
possible near the Gulf Coast as a maritime tropical airmass
infiltrates the northern Gulf of Mexico and the adjacent coastal
plain.  It appears the onset of stronger low-level flow contributing
to enlarged hodographs over portions of the central Gulf Coast will
occur after the end of the day 2 period (early Wednesday morning).
