SPC Jul 3, 2021 0100 UTC Day 1 Convective Outlook

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0756 PM CDT Fri Jul 02 2021 Valid 030100Z - 031200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are possible over a large part of the High Plains this evening but organized severe thunderstorms are not forecast tonight. ...Synopsis... Water-vapor imagery this evening shows a mid-level trough over the East with a ridge over the Upper Midwest. A mid-level shortwave trough was located over eastern MT and is forecast to move into ND later tonight. Thunderstorms will likely persist through the evening across the north-central High Plains given adequate moisture/instability and large-scale ascent afforded by the mid-level disturbance. Relatively warm mid-level temperatures noted on the Rapid City, SD 00z raob will likely limit hail potential when combined with gradual cooling this evening. Nonetheless, a strong gust/hail cannot be ruled out but storm activity will likely weaken by mid evening. Elsewhere, widely scattered showers/thunderstorms over parts of the Interior West and Gulf Coast/Atlantic coastal areas will slowly diminish during the evening. ..Smith.. 07/03/2021 Read more LIVE: spc.noaa.gov
