SPC Mar 28, 2022 2000 UTC Day 1 Convective Outlook

SPC 2000Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0234 PM CDT Mon Mar 28 2022 Valid 282000Z - 291200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible across portions of the western United States. ...20z Update... Changes are unnecessary with the 20z update. Isolated thunderstorms will continue to spread across portions of the western U.S. through the overnight hours. See discussion below for details. ..Leitman.. 03/28/2022 .PREV DISCUSSION... /ISSUED 1103 AM CDT Mon Mar 28 2022/ ...Western US... No changes have been made to the ongoing forecast. Scattered diurnally-driven showers and isolated thunderstorms are expected this afternoon from western MT southward across much of the Great Basin into central CA. This area will be under a cool upper trough with increasing mid-level moisture/lift and pockets of marginal instability. Small hail may occur in the stronger cells, but no severe storms are expected. After dark, an upper low and associated potent mid-level jet max will move across southern CA toward portions of NV/UT/AZ. Increasing large scale forcing for ascent and cooling temperatures aloft may aid in the persistence of isolated thunderstorms through the night across this region. Again, while small hail may accompany the strongest cores, no severe storms are anticipated. Read more CHECK UPDATE ZOOM GRAPHIC
