Convective Outlooks

Convective Outlooks
The convective outlooks serve as guidance to the local NWS forecast offices and are used by emergency managers, private sector meteorologists, media, and other weather customers concerned with public safety. Three separate risk areas (slight, moderate, and high) are used to describe the expected coverage and intensity for the categorical severe weather threat on days 1-3 along with severe weather probabilities for the potential threat.

.PREV DISCUSSION... /ISSUED 1024 AM CDT Tue Oct 27 2020/

...West TX/OK...
A deepening upper low over southeast AZ will track slowly eastward
today into the southern High Plains.  Widespread low-level warm
advection will lead to showers and isolated thunderstorms over west
TX and much of OK, with much of this precipitation atop sub-freezing
surface temperatures.

...Southeast LA to the FL Panhandle...
Tropical Storm Zeta is moving offshore and away from the Yucatan
Peninsula today.  An increasingly moist and marginally unstable air
mass will spread inland tonight across the central Gulf Coast
region, with the potential for isolated thunderstorms after
midnight.  The outer bands of the system are forecast to remain
primarily offshore tonight, with an increasing severe risk in parts
of this area tomorrow.
