janetjanet998 Posted April 23, 2020 MESOSCALE DISCUSSION 0453 NWS STORM PREDICTION CENTER NORMAN OK 1017 PM CDT WED APR 22 2020 AREAS AFFECTED...NORTHERN/CENTRAL LA CONCERNING...TORNADO WATCH 135... VALID 230317Z - 230445Z THE SEVERE WEATHER THREAT FOR TORNADO WATCH 135 CONTINUES. SUMMARY...A CORRIDOR OF INCREASED SEVERE POTENTIAL, INCLUDING THE THREAT OF A STRONG TORNADO, MAY BE DEVELOPING ACROSS CENTRAL LA. DISCUSSION...PAIR OF DISCRETE SUPERCELLS MOVING INTO NATCHITOCHES AND WINN PARISHES IN CENTRAL LA HAVE RECENTLY SHOWN SIGNS OF BETTER LOW-LEVEL ORGANIZATION WITH STRONGER INFLOW/OUTFLOW STRUCTURE AND A MORE DEFINED ZDR ARC. RECENT VAD PROFILE FROM POE SAMPLED 50 KT NEAR 1 KM AND OVER 400 M2/S2 OF 0-1 KM SRH. SOME NOCTURNAL STABILIZATION HAS TAKEN PLACE BUT THE VERY MOIST LOW-LEVELS AND ALREADY MATURE CHARACTER OF THE STORMS SUGGEST LIMITED INFLUENCE OF THIS STABILIZATION THUS FAR. ALL OF THESE FACTOR SUGGEST A CORRIDOR OF INCREASED SEVERE POTENTIAL, INCLUDING THE THREAT OF A STRONG TORNADO, MAY BE DEVELOPING ACROSS CENTRAL LA WHERE STP IS 4-6.

Moderately Unstable Posted April 23, 2020 4 minutes ago, Bob's Burgers said: No. The actual meso itself is barely in LCH's area. Oh. Oops. I've got nothing. I feel like this storm is just messing with mets now though. It weakens whenever there's a tor emergency issued. It shoots off some anticyclonics, satellites, and is now threading RIGHT between the warning county line polygons. Good SPC nowcasting: *sees tornado*: conditions are very appropriate for a tornado! However, that's also me, so, retracted. I wonder if moderate risk would have verified today. Starting with the earlier FOUR concurrent tornadic supercells in OK, today has felt more outbreaky than enhanced. I know we won't know until later. Just getting that sense. 1 Quote Share this post Link to post Share on other sites

Moderately Unstable Posted April 23, 2020 2 minutes ago, Indystorm said: I hope so, but I worry that kinematics will overcome thermodynamics. I was about to say, no, but, sure enough, the overshooting top has re-emerged on the cell. This storm should have its own wikipedia entry, all by itself. Just incredible how well organized this thing has been for so long. In any case, supercells can persist for awhile in sub-optimal environments, and actually for a cell this organized it's generating its own lift environment....but they're convective weather phenomena at the end of the day. While the cell won't necessarily die off immediately, it does stand to reason, that having been in such a conducive environment for so long, as it leaves that environment, it will weaken. Maybe slowly, maybe quickly. But, this storm won't maintain itself in stable air at the low levels. The southern of the two northern cells, is still in a favorable thermodynamic environment, AND shear environment, so it bears watching the next 30 mins to an hour. It also has the advantage that the long track cell has had--clear and relatively undisturbed air to the south for inflow. Quote Share this post Link to post Share on other sites
