Hail (a few instances near 1 inch diameter) and gusty winds (to 50 mph) may accompany this activity. DISCUSSION...Thunderstorms will continue to increase in coverage/intensity over the next few hours from far east TX into much of LA. Surface dewpoints in the mid/upper 60s to near 70 F beneath steep midlevel lapse rates are fostering MLCAPE generally around 1500 J/kg at midday. Meanwhile, 0-6 km effective shear magnitudes around 30-35 kt will be marginally favorable for supercells. Already a few cells across LA have shown transient, weak rotation. This environment will mainly support isolated hail (a few instances of near 1 inch diameter) and gusty winds (to 50 mph). Vertically veering low-level flow will support some potential for low-level rotation, and regional VWP data shows favorably curved (albeit small) low-level hodographs. Generally weak low-level winds and a lack of well-defined surface boundaries will likely limit tornado potential.=20 Given the expected transient and isolated nature of any stronger, well-organized cells, a watch is not expected at this time. ...Leitman/Hart.. 03/04/2024 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!7NZm5erOpJG_gA5oxmRDoADMzl4LbI9k1P29HayGcbEXEa6UEB_5V-gihCkCfqfPas43JcEZF= GVT7n71HslH1WaeW1M$ for graphic product...
