jojo762 Posted April 30, 2019 Share Posted April 30, 2019 TOR warning just issued in NW Arkansas. Probably going to be an area of an interest as LLJ axis will be INVOF. Link to comment Share on other sites More sharing options...

Sydney Claridge Posted April 30, 2019 Author Share Posted April 30, 2019 It looks like something may be trying to form SW of DFW now, especially just west of Stephenville. Will watch to see if this area of showers can form into some thunderstorms, as the atmosphere there seems volatile. EDIT: and just as I say this, SPC puts out an MD saying that a watch is likely for north-central Texas. Link to comment Share on other sites More sharing options...

janetjanet998 Posted April 30, 2019 Share Posted April 30, 2019 ESOSCALE DISCUSSION 0480 NWS STORM PREDICTION CENTER NORMAN OK 0153 PM CDT TUE APR 30 2019 AREAS AFFECTED...NORTH-CENTRAL TEXAS CONCERNING...SEVERE POTENTIAL...WATCH LIKELY VALID 301853Z - 302100Z PROBABILITY OF WATCH ISSUANCE...80 PERCENT SUMMARY...A SEVERE THREAT IS LIKELY TO DEVELOP THIS AFTERNOON ACROSS PARTS OF NORTH-CENTRAL TEXAS. LARGE HAIL, WIND DAMAGE AND AN ISOLATED TORNADO THREAT CAN BE EXPECTED. WEATHER WATCH ISSUANCE WILL LIKELY BE NEEDED. DISCUSSION...LATEST SURFACE ANALYSIS SHOWS A STATIONARY FRONT LOCATED IN SOUTHWEST OKLAHOMA AND NORTHWEST TEXAS. THE AIRMASS SOUTHEAST OF THE FRONT IS MODERATELY UNSTABLE WITH SURFACE DEWPOINTS NEAR 70 F. MLCAPE VALUES ARE GENERALLY ESTIMATED IN THE 2000 TO 3000 J/KG RANGE BY THE RAP. IN ADDITION, THE RAP HAS MODERATE DEEP-LAYER SHEAR ACROSS NORTH-CENTRAL TEXAS WITH 0-6 KM SHEAR ESTIMATED IN THE 35 TO 45 KT RANGE. THIS WILL BE FAVORABLE FOR SUPERCELLS. THE MAIN UNCERTAINTY IS THE EXACT TIMING OF INITIATION. THE LATEST RADAR IMAGERY SHOWS WEAK ECHOS IN THE VICINITY OF STEPHENVILLE. THE CURRENT THINKING IS THAT A STORM WILL DEVELOP IN THIS AREA SOMETIME BETWEEN 20Z AND 21Z. AFTER THAT, CONVECTIVE COVERAGE IS EXPECTED TO EXPAND WITH A CLUSTER MOVING EAST-NORTHEASTWARD TOWARD THE DALLAS-FORT WORTH METRO AREA, POSSIBLY APPROACHING THE RED RIVER LATER THIS AFTERNOON. SUPERCELLS WILL LIKELY BE ASSOCIATED WITH LARGE HAIL AND WIND DAMAGE. AN ISOLATED TORNADO THREAT IS ALSO EXPECTED AS LOW-LEVEL SHEAR INCREASES DURING THE LATE AFTERNOON AND EARLY EVENING.

Indystorm Posted April 30, 2019 Share Posted April 30, 2019 Becoming increasingly concerned for St. Louis area southward with increased insolation due to breaks in the clouds, backed winds with WF in area, 2500 ML CAPE and SPC meso discussion for southern IL.

Seems to me that the NWS in general is having issues with polygons on their maps and radars. Radarscope had it. Fairly strong couplet for a couple minutes but it weakened quickly.
