Day 2 Convective Outlook

Valid 091200Z - 101200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM PARTS OF THE
NORTHERN ROCKIES INTO PARTS OF THE NORTHERN PLAINS...

...SUMMARY...
Isolated to scattered thunderstorms are expected on Saturday
afternoon and evening from parts of the northern Rockies eastward
across much of the northern Plains. Marginally severe storms could
also occur across parts of the southeastern U.S, and along parts of
the Atlantic Seaboard.

...Northern Rockies/Northern Plains...
An upper-level ridge will be in place on Saturday across the
northern Plains, with southwest anticyclonic mid-level flow located
from the northern Rockies into the northern High Plains. At the
surface, a cold front is forecast to move southeastward into
Montana. Surface dewpoints in the lower to mid 60s F ahead of the
front, should enable the development of moderate instability by
afternoon from eastern Montana into parts of the Dakotas.
Thunderstorms will develop in the higher terrain of western and
central Montana, with storms moving eastward into the lower
elevations. Other thunderstorms are expected to form further east
near a pocket of strong instability in western and central North
Dakota. These storms could move eastward across eastern North Dakota
and into northwestern Minnesota during the evening.

A relatively broad warm sector is forecast Saturday afternoon, from
central Montana eastward into the Dakotas. Forecast soundings along
this corridor at 00Z/Sunday have moderate deep-layer shear, mainly
due to strong speed shear in the mid-levels. 700-500 mb lapse rates
are forecast to be in the 7.0 to 8.0 C/km range, suggesting
supercells with large hail will be possible. The hail threat should
remain somewhat isolated due to warm temperatures aloft, in the 10
to 14 Celsius range at 700 mb. Supercells and bowing line segments
will have potential for damaging wind gusts. If a cluster of storms
can beco*e organized during the evening, a localized swath of wind
damage could occur. But that will depend upon a number of factors
including the exact distribution of instability, which is uncertain
at this time.

...Southeastern U.S./Atlantic Seaboard...
An upper-level trough will move eastward to near the eastern
Seaboard by early afternoon on Saturday. At the surface, a cold
front will advance southward across the Mid-Atlantic and southern
Appalachians. Ahead of the front, a moist airmass will be in place
from the Gulf Coast States into the Carolinas and Virginia. Although
deep-layer shear will be relatively weak, areas that heat up
sufficiently will have moderate instability and steep low-level
lapse rates. Cells that initiate and persist will have potential for
marginally severe wind gusts. Other cells will be pulse in nature,
and could produced brief strong wind gusts.
