Overview

During the afternoon of the 24th of June a few thunderstorms had popped up along the HWY 60 corridor. Later in the evening thunderstorms moved into the combined Oklahoma and Texas Panhandles from New Mexico. These storms lined out from I-40 near Endee, NM and ran northeast to around Texline. As this SW to NE oriented line of storms moved east the storms in the north ran into a better environment for the potential to become strong to severe, and did become severe with wind gusts of 70 mph measured at a mesonet site near Palo Duro Reservoir. As this storm approached Perryton around 9 PM CDT one of the storms started to rotate, enabling hail growth and strong winds. Hail was reported north of Perryton up to the size of ping pong balls which combined with strong winds to damage some windows on a farmhouse along with other damage around the property. As this storm moved northeast it created winds estimated at 85 mph, damaging several power distribution poles from Balko to Elmwood, OK, leaving much of Beaver County without power. This storm quickly weakened not long after causing the power loss.

For June 25th, during the afternoon hours of peak heating, thunderstorms formed along a boundary from Endee, NM to Amarillo and from Amarillo up to Canadian. Also some thunderstorms formed in SE CO and eventually traveled along the northern edge of the OK Panhandle from west to east. The environment was primed for strong damaging winds and large hail. Automated weather equipment located throughout both the OK and TX Panhandles measured wind gusts from these storms at well over 60 mph. The highest wind gust measured was 85 mph at the mesonet site near Hooker, Oklahoma. Some thunderstorm wind damage was also reported, especially in Texas County, Oklahoma. The largest hail stone reported was 2 inches in diameter near Clarendon, TX.

Rain Reports

The thunderstorms on both days were relatively slow moving, allowing for some locations to receive a good amount of rainfall, especially on the 25th. On the 25th, the West Texas Mesonet site 6 miles east of Canadian received 4.47" of rainfall, with radar estimates suggesting upwards of 6 inches fell south of this gauge location.

Rainfall over the 24 hours ending at 7AM on June 26th. Estimated using a combination of ASOS, West Texas Mesonet, Oklahoma Mesonet, COOP, and CoCoRaHs ground observations and radar rain estimates

Environment

As evidenced by relatively weak flow in the upper (left) and middle (center) parts of the atmosphere, the June 24th event was kicked off by only a weak disturbance aloft. However, lower level moisture (right) was plentiful, so storms did develop. Moving ahead to June 25th, a large scale upper system approached. With the moisture still around, thunderstorms developed in abundance for many hours.

Upper atmosphere (250mb) wind plots from June 24th and 25th.	Middle atmosphere (500mb) analysis from June 24th and 25th.	Lower level (850mb) analysis from June 24th and 25th.

While wind shear (left) was enough for severe storms on the 24th, it increased ahead of that large scale upper system for the 25th, with more widespread severe storms occurring as a result. Potential downdraft strength (center) was very high both days. The overall moisture in the atmosphere (right) increased for the 25th, leading to noticeably higher rainfall.

Wind shear from June 24th and 25th.	Measure of potential downdraft strength (DCAPE) from June 24th and 25th. Values above 1500 J/kg are high for the Panhandles.	Measure of potential for heavy rainfall (precipitable water) from June 24th and 25th. Values above 1.5" are high for the Panhandles.
