Convergence of moisture along a stationary front in southern Arkansas triggered thunderstorms during the evening of June 14th. With an unstable air mass south of the front and a strong jet stream over the frontal zone sustaining robust updrafts, these storms quickly became severe and moved east-southeast across portions of southeast Arkansas.

NWS Jackson, MS wrote its last area forecast discussion before the first event at Jun 14, 6:13 PM CST, 1 hour 22 minutes earlier.
Area Forecast Discussion National Weather Service Jackson MS 713 PM CDT Wed Jun 14 2023 ...New AVIATION... .DISCUSSION... Issued at 357 PM CDT Wed Jun 14 2023 Tonight through Thursday: A significant severe weather event (including the threat for intense damaging wind, very large hail, and torndoes) continues into early this evening along with the potential for flash flooding. As of now, we've received reports of 5 inch hail (verified by photo in Brooksville) and multiple 80+ mph wind reports over the northern half of the forecast area. The environment remains extreme for any time of the year, and especially for June, with effective deep layer bulk shear approaching 70kt combined with steep mid/upper level lapse rates and extreme instability (e.g., 2-6km > 8.5 deg C, MLCAPE near 5000 j/kg, including hail producing layer CAPE in excess of 1300 j/kg, etc.). Supercells/bowing segments are expected to continue to move mainly along/south of the I-20 corridor through early evening with significant wind speeds > 80 mph and very large hail continuing to be possible. It will continue to be a challenge to anticipate discrete cell development and mesoscale influences, but the general trend has been for additional storm development to take place further south. There is uncertainty with convective evolution and all interests in the area are encouraged to have heightened awareness. Will continue to message the event heavily and update as radar/obs trends allow. Later tonight, we will monitor for the potential for additional upstream storm development and perhaps an increasing threat for flash flooding as moisture transport continues to take place with the potential for convective to be anchoring over eastern MS especially. With H850 flow roughly parallel to the frontal boundary and precipitable water > 1.5 inches with very moist low level air, we'll need to monitor for training of convective elements. /EC/ Thursday Night through Early Next Week: And the stormy weather pattern continues...This current pattern we've been under the last few days will continue through the early parts of next week. For starters, a stalled boundary stretched across central Mississippi along with a disturbance riding along a subtropical ridge will bring the possibility of severe weather Friday mainly during the late morning through the afternoon hours. Damaging wind gusts and hail sizes ranging from quarter to golfball size will be the main impacts with this system. will maintain the 'Slight Risk' across the north and 'Marginal' elsewhere however, don't be surprised if the Slight risk gets extended further south. Saturday will have lingering flow from Friday however we'll have a chance to breathe. While severe parameters aren't impressive Saturday, afternoon showers and thunderstorms will be possible. Sunday a surface low associated with ongoing troughing across the Midwest will deepen and push a disturbance across the Mid and Deep south. We could potentially see more severe weather on Sunday but will hold off on mentioning anything in the HWO right now. Starting Friday, we will see influence from the subtropical ridge in regards to heating especially across the southwest. Dewpoints will increase into the mid 70s increasing humidity and combined with surface high temperatures in the mid to high 90s, will create dangerous heat stress conditions. Heat indices will reach 105-110. This will result in the potential for heat exhaustion, especially in the late morning to afternoon time frame. Heat stress will continue through early next week with the main time frame between 10AM-6PM each day. It is suggested to limit outdoor activities. /JNE/ && .AVIATION... (00Z TAFS) Issued at 653 PM CDT Wed Jun 14 2023 Severe TSRA with damaging wind gusts and large hail continue to be the primary concerns as we go through the forecast period. Scattered supercells may impact the area, but trying determine specific timing/location will be very difficult. Otherwise, expect the typical late night/early morning stratus development given the persistent weather pattern. Strong mixing will allow for gusty aftn/evng sfc wind during the day with low level wind shear issues greatest at night. /EC/ && .PRELIMINARY POINT TEMPS/POPS...
