Day 1 Convective Outlook

0800 PM CDT Thu Jul 18 2024

Valid 190100Z - 191200Z

....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER COASTAL
PORTIONS OF THE CAROLINAS...CENTRAL HIGH PLAINS...AND CENTRAL
MONTANA...

....SUMMARY...
Isolated strong to damaging gusts will be possible this evening
across the coastal Carolinas, portions of the central High Plains,
and over central Montana. A few instances of large hail may also
occur over the central High Plains.

....Southeast/Mid-Atlantic Coast...
Have removed the Slight Risk and trimmed the Marginal Risk to along
and immediately downstream of ongoing line/clusters of
thunderstorms. Despite mostly non-severe storms during the past few
hours, some potential will remain for a couple more hours for a
stronger updraft to briefly pose a risk for strong convective gusts.
This potential will diminish further after 03/04z as gradual
nocturnal cooling continues.

....Central High Plains...
Isolated severe storms have occurred over the past few hours east of
the foothills in the presence of moderate buoyancy and 25-30 kts of
northwesterly shear.  Isolated large hail and damaging gusts will
remain possible mainly this evening, with the severe wind potential
locally maximized where clustering of storms occurs.

....Central MT...
A mid-level shortwave trough is expected to continue to provide
large-scale ascent through the evening hours, allowing scattered
thunderstorms to continue to develop and move generally
east/southeast. The boundary layer remains deeply mixed and the
potential for isolated strong/damaging gusts will persist into the
late evening.
