  "textContent": "MD 0551 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR NORTH-CENTRAL AND NORTHEAST OKLAHOMA\n\n\n\n\n    Mesoscale Discussion 0551\n    NWS Storm Prediction Center Norman OK\n    0500 PM CDT Sun Apr 26 2026\n\n    Areas affected...North-central and Northeast Oklahoma\n\n    Concerning...Severe potential...Watch likely\n\n    Valid 262200Z - 270000Z\n\n    Probability of Watch Issuance...80 percent\n\n    SUMMARY...Convective initiation will be possible this evening across\n    north-central Oklahoma. If this takes place, a tornado threat will\n    become likely. Tornado watch issuance is anticipated over the next\n    hour.\n\n    DISCUSSION...Latest surface analysis shows a very moist airmass in\n    place over much of Oklahoma with surface dewpoints in the upper 60s\n    and lower 70s F. A surface trough is oriented from southwest to\n    northeast across north-central Oklahoma, where low-level convergence\n    is maximized. Along this zone, satellite imagery shows an agitated\n    field of cumulus along the I-35 corridor in northern Oklahoma. To\n    the east of the trough, the air is very unstable with the RAP\n    showing MLCAPE in the 3000 to 4000 J/kg range. In addition, a strong\n    wind field is in place with 0-6 km shear estimated by the RAP to be\n    in the 35 to 45 knot range. While large-scale ascent does not look\n    to be strong near the surface trough, low-level convergence could be\n    enough to initiate convection at some point this evening. If this\n    where to occur, then rapid supercell development would be expected,\n    and a tornado threat would become likely. Large hail and severe wind\n    gusts would also be likely.\n\n    ..Broyles/Leitman.. 04/26/2026\n\n    ...Please see www.spc.noaa.gov for graphic product...\n\n    ATTN...WFO...TSA...OUN...\n\n    LAT...LON   36989591 36849528 36529508 36279509 36009522 35899582\n                35909748 35899817 36069853 36329864 36719855 36999816\n                36989735 36989591\n\n    MOST PROBABLE PEAK TORNADO INTENSITY...120-145 MPH\n    MOST PROBABLE PEAK WIND GUST...55-70 MPH\n    MOST PROBABLE PEAK HAIL SIZE...2.00-3.50 IN\n\n\n\nRead more",
