WW 98 SEVERE TSTM TX CW 100135Z - 100900Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 98 NWS Storm Prediction Center Norman OK 835 PM CDT Tue Apr 9 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Central and South Texas Coastal Waters * Effective this Tuesday night and Wednesday morning from 835 PM until 400 AM CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph likely Scattered large hail and isolated very large hail events to 2.5 inches in diameter likely A tornado or two possible SUMMARY...Thunderstorms are expected to rapidly develop this evening along a dryline and track eastward across the watch area. Intense supercells and bowing storms capable of very large hail and damaging winds are possible. The severe thunderstorm watch area is approximately along and 75 statute miles east and west of a line from 25 miles north of New Braunfels TX to 70 miles south southwest of Alice TX. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for severe thunderstorms in and close to the watch area. Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. Severe thunderstorms can and occasionally do produce tornadoes. && OTHER WATCH INFORMATION...CONTINUE...WW 95...WW 96...WW 97... AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 550. Mean storm motion vector 25035. ...Hart Read more

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0215 AM CDT Wed Apr 10 2024 Valid 121200Z - 131200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast on Friday. ...East... Deep surface cyclone near Lake Huron at 12Z Friday should occlude and slowly weaken as it continues northeastward into western Quebec. The arcing occluded front across parts of the Northeast may be a focus for low-topped convection during the late morning to early afternoon. Surface-based destabilization appears to be rather limited, but its plausible that scant to meager buoyancy might develop over the eastern NY vicinity. Low to deep-layer wind profiles are conditionally favorable for organized updrafts and this corridor will need to be monitored in later outlooks for a potential cat 1-MRGL risk highlight. ...West... An amplified shortwave trough will approach but remain west of the CA coast through 12Z Saturday. While the bulk of PW increase will largely be confined to parts of CA and the OR Pacific Coast, modest moistening should occur within the deep-layer southwesterly flow regime, west of the mid-level ridge that will become centered across the High Plains. Scant to meager surface-based buoyancy is expected by Friday afternoon and this should support isolated to scattered high-based, low-topped thunderstorms from the Sierra NV across the northern Rockies. A very isolated severe wind gust is possible given the steep lapse-rate environment, but an organized severe threat appears unlikely. ..Grams.. 04/10/2024 Read more
