Farther to the west, thunderstorms produced hail and damaging winds across parts of north-central and southeast Nebraska, as seen in 1-minute GOES-16 Visible and Infrared images (below)<\/strong><\/em>. One notable feature of interest was the cooler (lighter shades of gray) west-to-east oriented swath of hail on the ground in the wake of the southern Nebraska storm — even though that storm was initially producing primarily small-diameter hail (1.00 inch or less), that hail fell at a high enough rate to accumulate and remain on the ground for several hours. Another similar (but more subtle) southwest-to-northeast oriented swath of accumulating hail was evident in the wake of the storm over north-central Nebraska.<\/p>\n

A closer view of the southern Nebraska storm is shown below, using 1-minute GOES-16 Infrared images with a color enhancement tailored to highlight the colder swath of hail accumulation (brighter shades of cyan to darker shades of blue). Surface 10.3 \u00b5m infrared brightness temperatures within the narrow hail swath were in the 5-8\u00baC range, in contrast to 10-13\u00baC over adjacent bare ground. A few Local Storm Reports (2328 UTC<\/strong><\/a> | 0004 UTC<\/strong><\/a> | 0102 UTC<\/strong><\/a> | 0157 UTC<\/strong><\/a>) mentioned hail accumulation or a long duration of hail.<\/p>\n

In a toggle between the GOES-16 Land Surface Temperature<\/strong><\/a> (LST) derived product at 0000 and 0100 UTC (below)<\/strong><\/em>, LST values within the narrow hail swath were in the low-middle 50s F (darker shades of blue), compared to the low-middle 60s F (shades of green) over adjacent bare ground. Another cold LST hail swath was apparent in the wake of the thunderstorm over north-central Nebraska.<\/p>\n

Here's something we don't see every day:

Tonight's storm was such a prolific hail producer that the lingering hail on the ground can be seen on IR satellite! This is due to the temperature differences between the warm\/dry ground and cooler hail-covered ground#scienceiscool<\/a> ? pic.twitter.com\/5WxQT4smzZ<\/a><\/p>— NWS Hastings (@NWSHastings) May 7, 2023<\/a><\/blockquote>
