High-altitude turbulence over the Southern Plains

GOES-16 (GOES-East) Upper-level Water Vapor (6.2 µm) images with pilot reports of turbulence — with and without contours of RAP40 model Maximum Wind Speed (above) showed an anomalously-deep 500 hPa trough over the Southern Plains, where there was an anomalously-strong 250 hPa jet streak developing along its forward (eastern) edge. A number of pilot reports of moderate to... Read More

GOES-16 (GOES-East) Upper-level Water Vapor (6.2 µm) images with pilot reports of turbulence — with and without contours of RAP40 model Maximum Wind Speed (above) showed an anomalously-deep 500 hPa trough over the Southern Plains, where there was an anomalously-strong 250 hPa jet streak developing along its forward (eastern) edge. A number of pilot reports of moderate to severe turbulence were seen within the exit region of this jet streak.

In GOES-16 Upper-level Water Vapor images with and without an overlay of a Turbulence Probability product (below), higher probability values were apparent in the area near/along the axis of the 250 hPa jet streak (and the related pilot reports of turbulence).

Severe thunderstorms in Texas

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include time-matched SPC Storm Reports — and showed the development severe thunderstorms across parts of Texas (and far southeastern New Mexico) during the afternoon and early evening hours on 24 May 2022. These storms produced hail as large as 4.00 inches in diameter, a tornado and damaging winds as... Read More

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include time-matched SPC Storm Reports — and showed the development severe thunderstorms across parts of Texas (and far southeastern New Mexico) during the afternoon and early evening hours on 24 May 2022. These storms produced hail as large as 4.00 inches in diameter, a tornado and damaging winds as strong as 78 mph. Signatures of Above-Anvil Cirrus Plumes (reference | VISIT training) were also evident .

In the corresponding 1-minute GOES-16 “Clean” Infrared Window (10.35 µm) images (below), pulsing overshooting tops exhibited infrared brightness temperatures in the -70 to -79ºC range.

Severe thunderstorms in New Mexico and Texas

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include time-matched SPC Storm Reports — and showed the development of 2 supercell thunderstorms near the New Mexico / Texas Panhandle border late in the day on 23 May 2022. The northern storm produced hail as large as 2.50 inches in diameter, while... Read More

1-minute Mesoscale Domain Sector GOES-16 (GOES-East) “Red” Visible (0.64 µm) images (above) include time-matched SPC Storm Reports — and showed the development of 2 supercell thunderstorms near the New Mexico / Texas Panhandle border late in the day on 23 May 2022. The northern storm produced hail as large as 2.50 inches in diameter, while the southern storm produced a very large tornado and damaging winds as strong as 80 mph. Signatures of Above-Anvil Cirrus Plumes (reference | VISIT training) were also seen.

In the corresponding 1-minute GOES-16 “Clean” Infrared Window (10.35 µm) images (below), warmer AACP signatures (shades of yellow) were evident, downwind of cold overshooting tops — these pulsing overshooting tops exhibited infrared brightness temperatures as cold as -77ºC.
