Severe Weather Over E TX/LA/AR
Posted: Sat Jun 19, 2004 5:47 pm
Bow echo over Arkansas continues to progress eastward with damaging wind threat but the main focus that caught my eye on radar was in about a hr will see a new cluster form with conflicting outflow boundries over Eastern TX. SBCAPE is not that high in this region so we might see these storms organize into a broken areal.
LA is another hot spot for severe weather with high SBCAPE values and no shear providing for a derecho favored environment, but were in no way gonna see derecho material due to short lived nature of these storms. Low LCL heights with moist PBL and dry mid levels will lead to strong convective instability and will enhance damaging wind threat with DCAPE reaching 1000j/kg. Very strong low level stretching thankfully doesnt have anything to work with resulting in only a damaging wind threat. With very weak flow aloft combined with PWATS to 2" will contribute to flooding.
A lot of these warnings out are probably unncessary with lack of vertical shear resulting in rain falling in updraft reflecting high DBZ on radar,,,,,lot of these warnings are not reporting any damage yet.
