SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0159
AM CST Sun Dec 20 2020
Valid 221200Z - 231200Z
...NO THUNDERSTORM AREAS FORECAST...
...SUMMARY... Thunderstorms are not expected on Tuesday.
...Synopsis... Shortwave ridging is anticipated to be in place over
the central CONUS early Tuesday, with shortwave troughs flanking on
either side. Overall pattern is expected to progress eastward with
the western CONUS shortwave trough moving east-southeastward while
deepening. This deepening may lead to bifurcation of the wave, with
the southern portion over the Four Corners region early Wednesday.
At the surface, lee troughing is expected to deepen ahead of the
approaching shortwave trough. Surface cyclogenesis is anticipated
over the northern High Plains, with the resulting low moving
eastward across the northern Plains. Secondary cyclogenesis is
possible over the central High Plains late Tuesday night/early
Wednesday morning. By 12Z Wednesday, an expansive area of low
pressure encompassing both of these lows will cover much of the
Plains and MS Valley.
A strong cold front attendant to these surface lows will sweep across
the northern and central Plains. However, low-level moisture will
be confined to central/south TX, and the resulting lack of buoyancy
will preclude thunderstorm development along the front.

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK
0344 AM CST Sun Dec 20 2020
Valid 231200Z - 281200Z
...DISCUSSION... Deep upper troughing is expected to be in place
over the western and central CONUS early D4/Wednesday. This upper
troughing is then expected to progress eastward as an embedded
shortwave trough moves across the central Plains. Another shortwave
is forecast to follow quickly in the wake of the first, moving
across the southern Plains D4/Wednesday night.
By early D5/Thursday, a deep upper trough will likely extend from
Ontario southward into the southern Plains, with strong flow aloft
surrounding it. Continue eastward motion is expected into D6/Friday,
with further deepening/maturing of the system.
Some severe potential appears possible across central/east TX into
the Lower MS Valley on D4/Wednesday as the cold front moves through,
and the Carolinas/southern VA late D5/Thursday or early D6/Friday.
However, in both cases, instability is expected to be modest, which
will limit coverage. Additionally, differences in timing within the
guidance results in uncertainty regarding location. These factors
limit predictability. Stable conditions are currently forecast
after D6/Friday.
