Day 2 Convective Outlook

1100 AM CST Mon Feb 27 2023

Valid 281200Z - 011200Z

....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected on Tuesday.

....Synopsis...
Gradual height rises and anticyclonic flow aloft will develop over
much of the East on Tuesday as a large-scale upper trough develops
over the West. Stable air will exist over much of the CONUS with a
high over the Ohio Valley and cool temperatures over the interior
West. Low-level moisture will linger along the Gulf Coast, extending
from TX into FL, and will gradually spread northward overnight in
response to a low-amplitude wave within the southwesterly flow
regime over the Plains. Only modest warm/moist advection is expected
as 850 mb winds increase to 20-30 kt from TX into the Deep South,
and little instability will be present to support storms.

To the west, cold air aloft will exist across the Pacific Northwest,
as a strong jet streak dives southward within the backside of the
trough. This will enhance lift over northern CA and perhaps into
interior northern CA, and very weak instability may be present to
support a few lightning flashes. Coastal OR and northern CA may also
experience a few low-topped storms as a surface trough develops with
increasing shoreline convergence.
