Day 2 Convective Outlook 
NWS Storm Prediction Center Norman OK
0100 AM CDT Mon Aug 08 2022

Valid 091200Z - 101200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Daytime thunderstorms will be possible across much of the CONUS, but
little severe weather is anticipated.

...Synopsis and Discussion...
An upper high will remain centered over CO while a shortwave trough
moves southeastward across MB and ON, bringing strong northwest flow
across the northern Plains and upper Great Lakes. A front will
stretch from the central Plains into the OH Valley and across
southern New England, providing a focus for scattered daytime
storms. The aforementioned strong flow aloft will remain well behind
this front, and therefore have little effect on severe potential
along the boundary. However, ample low-level moisture and MUCAPE
over 1000 J/kg will favor pulse storms, and isolated strong gusts
may occur along the length of the boundary.

To the west, an upper low over the Pacific will drift toward coastal
northern CA and OR, providing moderate meridional flow aloft to the
region. A surface trough will develop over central OR during the
afternoon, providing weak convergence and supporting scattered
thunderstorms. Forecast soundings show minimal instability, but
steep boundary-layer lapse rates may yield sporadic strong gusts,
possibly extending into NV as well where midlevel moisture will be
increasing.

Elsewhere, localized strong wind gusts may occur with diurnal
frontal activity from OK into parts of northwest TX. Temperatures
will be hot, MUCAPE generally below 1000 J/kg, and winds aloft quite
weak.
