Large Hail, Damaging Winds and a Possible Tornado! (credit: NOAA, GOES-16, College of DuPage NEXLAB)
DISCUSSION: Severe weather has been a threat in the forecast on Friday, April 21st, in the southern Plains for the past few days. The two images above from the GOES-16 satellite depict today’s convection in great detail both in the visible and the mid-level water vapor imageries. Thunderstorms began to develop this morning overspreading Oklahoma and Texas. As the day progressed, instability increased and convection blossomed in western Arkansas where a few thunderstorm wind gusts were reported. Currently the SPC’s preliminary storm reports features multiple wind and hail reports. These numbers are expected to increase as the SPC in Norman, Oklahoma recently updated the forecast to include a tornado watch which states, “A few tornadoes possible. Scattered large hail and isolated very large hail events to 2 inches in diameter possible. Scattered damaging wind gusts to 70 mph possible”. These areas include northeast Texas, southeast Oklahoma, and southwest Arkansas.
A moderate amount of CAPE accompanied with enough wind shear will produce severe weather in these areas and hence the threat for isolated tornadoes. A dangerous night is on the way for many. If in the forecast areas, be on the lookout for the latest watches and warnings.
