A "Particularly Dangerous Situation" Tornado Watch has been issued Wednesday night through Thursday morning for extreme southeast OK, northeast TX, southern AR, and northern LA from 9:15 to 6:00 am CST. The strong trough is currently moving across the southern Plains as of 10:00 pm, with a strong surface low exploding in southern OK. To the east of this rapidly intensifying low, a 40-60 kt low-level jet has developed over LA and AR yielding extreme low-level wind shear values. Moderate instability with a weak cap in place in the warm sector will allow for surface-based convective development, and thus strong tornadoes will be possible. The Storm Prediction Center mentions the liklihood of a "nocturnal tornado outbreak" in this region tonight. Displayed below is the graphic for this PDS Tornado Watch, along with the wind profile from Shreveport, LA, and the radar image from Little Rock as fo 9:38 CST.
As seen in the VAD from Shreveport above, the wind at 2000 ft above the surface was 45 knots as of 9:38 pm, which is yielding 0-1 km helicity values of 500-600 m2/s2 (more than sufficient for large tornadoes). Storms were beginning to develop over southern AR, which will likely become tornadic supercells in the very near future. I'll be watching this situation closely throughout the night, and will post updates continuously. Stay tuned!
