Day 2 Convective Outlook  
NWS Storm Prediction Center Norman OK
1253 AM CST Mon Nov 06 2017

Valid 071200Z - 081200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe storms are not expected across the U.S. Tuesday.

...Synopsis...
Low-amplitude mid-level troughing extending from the Great Lakes
westward into the Intermountain West will advance slowly
southeastward Tuesday, while ridging increases in the wake of this
feature over the western U.S.  As the trough advances, a roughly
west-to-east surface cold front over the southeast quarter of the
country will continue a steady southeast advance toward the Gulf
Coast.  Behind the front, high pressure will expand to cover much of
the country.

Showers and a few thunderstorms are expected in the vicinity of --
and to the cool side of -- the advancing surface front, particularly
from the Mid-South region eastward.  Convection farther west will
likely remain more spotty/uncertain, though with some increase
possible after dark in conjunction with an increase in low-level
warm advection.  In all areas, severe storms are not expected.

Day 3 Convective Outlook  
NWS Storm Prediction Center Norman OK
0127 AM CST Sun Nov 05 2017

Valid 071200Z - 081200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe storms are not expected across the U.S. Tuesday.

...Synopsis...
Positively tilted troughing within the upper flow field across the
U.S. will gradually shift southeastward out of the Rockies and
across the Plains/Midwest.  Meanwhile, ridging is progged to expand
over the West in the wake of this trough, and ahead of a large upper
low moving south-southeast out of the Gulf of Alaska.  

At the surface, high pressure will prevail across a large/expanding
portion of the country in the wake of a surface cold front moving
slowly southeastward across Southeast/southern Plains.

Showers and scattered thunderstorms are expected in the vicinity of
the front during the period, and flow aloft would otherwise be
sufficient to support organized convection.  However, relatively
weak lapse rates and weak large-scale subsidence atop the warm
sector should hinder convective intensity -- and preclude
appreciable severe risk.
