• Flash Flood and Hail in Tennessee, July 12, 202070 kt wind · 4 eventsAn upper-level disturbance kicked off numerous thunderstorms across the western Ohio Valley. This activity produced an outflow boundary that sagged into West Tennessee and kicked off more thunderstorms during the morning hours on July 12, 2020.
• Hail in Nebraska, July 12, 20202.75 in hail · 7 eventsOne group of thunderstorms, including a supercell, produced golf ball size hail in the central Sandhills during the late morning. Another cluster of supercells developed late afternoon in far southwest Nebraska, resulting in up to baseball size hail.
• Hail in South Dakota, July 12, 20201 in hail · 1 eventA thunderstorm briefly became severe over southern Jackson County, producing hail around quarter size.
• Hail and Damaging Winds in Alabama, July 12, 20201 in hail · 33 eventsA MCS moving southward out of Tennessee encountered a very unstable air mass across Central Alabama. Surface based CAPE values were 3000-5000 J/kg ahead of the MCS. The leading edge of the MCS produced widespread wind damage during the late morning and afternoon hours.
• Damaging Winds in Mississippi, July 12, 2020$90,000 · 53 kt wind · 3 eventsA mesoscale convective system which began overnight raced south from Tennessee through eastern parts of Mississippi during the morning and afternoon on July 12th. Occasional strong to severe wind gusts accompanied this line of strong to severe storms as it moved south.

• Hail in Colorado, July 12, 20201.75 in hail · 5 eventsLarge amounts of moisture and instability supported scattered severe thunderstorms across southern Colorado during the afternoon and evening hours. While large hail was observed across mainly the Pikes Peak region, there were some isolated reports over the far eastern plains.
• Hail in Colorado, July 12, 20202 in hail · 6 eventsSevere thunderstorms produced large hail across parts of Lincoln and Washington counties. The hail ranged in size from 1 to 2 inches in diameter.
• Damaging Wind in Georgia, July 12, 2020$5,000 · 50 kt wind · 1 eventModerate instability and strong afternoon heating resulted in an isolated severe thunderstorm in central Georgia during the late afternoon.
• Flash Flood and Damaging Wind in West Virginia, July 12, 2020$51,000 · 2 eventsA shortwave trough moved through an overall broad trough across the central Appalachians on the 12th. This forced showers and thunderstorms to form, resulting in isolated wind damage and flash flooding.
• Hail and Damaging Winds in Kentucky, July 12, 2020$500 · 1 in hail · 5 eventsScattered afternoon and evening thunderstorms were ongoing across eastern Kentucky Sunday June 12. A few of these storms reached severe limits, producing instances of hail and wind damage across Morgan, Magoffin, and Bath Counties.
• Tornado and Flash Flood in Colorado, July 12, 2020$4,000 · 2.5 in hail · 14 eventsThunderstorms initiated along a dry line in central Colorado moving east and forming a cluster of supercells that produced up to 70 mph wind gusts and large hail up to tennis ball in size across Yuma County.
• Hail and Damaging Wind in Ohio, July 12, 2020$5,000 · 50 kt wind · 2 eventsA broad upper level trough was over the middle Ohio River Valley on the 12th. As a shortwave trough moved through the larger synoptic feature, showers and thunderstorms developed. Isolated tree damage resulted from the stronger storms.
• Damaging Winds in Pennsylvania, July 12, 202050 kt wind · 4 eventsA few strong to severe thunderstorms developed over Pennsylvania on July 12. These were associated with a cold front and surface trough approaching a warm and moderately unstable but weakly sheared air mass.
• Hail and Damaging Winds in Alabama, July 12 to 19, 20201.75 in hail · 11 eventsA cluster of thunderstorms developed in a northwest upper level flow pattern and moved southward across the area. These storms caused damaging winds in excess of 60 mph, large hail and very heavy rain as they moved across the area.
• Damaging Wind in Florida, July 12, 202050 kt wind · 1 eventA cluster of thunderstorms developed in a northwest upper level flow pattern and moved southward across the area. These storms caused damaging winds in excess of 60 mph, large hail and very heavy rain as they moved across the area.
• Hail and Damaging Wind in New Mexico, July 12, 202061 kt wind · 2 eventsA back door frontal boundary that brought higher moisture levels and scattered thunderstorms to northeast New Mexico on July 11, 2020 became stationary over the area through July 12, 2020.
• Hail and Damaging Winds in Nebraska, July 12, 2020$528,000 · 2.5 in hail · 22 eventsThunderstorms initiated along a dry line in central Colorado moving east and forming a cluster of supercells that moved through Dundy, Hitchcock, and Red Willow counties along the Kansas and Nebraska border.
