WW 342 SEVERE TSTM TX CW 281605Z - 282300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 342 NWS Storm Prediction Center Norman OK 1105 AM CDT Tue May 28 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southeast Texas Coastal Waters * Effective this Tuesday morning and evening from 1105 AM until 600 PM CDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph likely Scattered large hail likely with isolated very large hail events to 2.5 inches in diameter possible SUMMARY...Thunderstorms are expected to intensify through the afternoon and spread southeastward across the watch area. The strongest cells will be capable of damaging wind gusts and large hail. The severe thunderstorm watch area is approximately along and 65 statute miles north and south of a line from 65 miles west southwest of College Station TX to 25 miles north northeast of Port Arthur TX. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU2). 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 341... 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 500. Mean storm motion vector 29035. ...Hart Read more

MD 1048 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR PORTIONS OF EXTREME NORTHEAST NEW MEXICO INTO THE OKLAHOMA PANHANDLE...NORTHERN TX PANHANDLE...FAR EASTERN COLORADO...FAR WESTERN KANSAS
Mesoscale Discussion 1048 NWS Storm Prediction Center Norman OK 0156 PM CDT Tue May 28 2024 Areas affected...portions of extreme northeast New Mexico into the Oklahoma Panhandle...northern TX Panhandle...far eastern Colorado...far western Kansas Concerning...Severe potential...Watch likely Valid 281856Z - 282030Z Probability of Watch Issuance...80 percent SUMMARY...The severe threat is increasing across portions of the central and southern High Plains. Large hail and severe gusts are the main threat, and a couple of hail stones may exceed 2 inches in diameter. A WW issuance may be needed soon to address the increasing severe threat. DISCUSSION...With strong diurnal heating, temperatures are rising into the 80s F, amid mid 50s to lower 60s F dewpoints. With 8+ C/km mid-level lapse rates overspreading this airmass, MLCAPE is exceeding 2000 J/kg. Visible satellite and MRMS mosaic radar imagery shows convective initiation underway over extreme northeast NM. However, 18Z mesoanalysis shows MLCINH is still present over the warm sector. Nonetheless, continued surface heating should erode the cap through the afternoon, supporting the development of additional storms. 18Z mesoanalysis depicts modestly curved but elongated hodographs, suggesting splitting supercells as the initial mode of convection. The supercells will be accompanied by a severe wind and hail threat. An instance or two of 2+ inch diameter hail or a tornado also cannot be ruled out. With time, storms may merge into clusters (perhaps one or more MCSs). If an MCS can develop, severe gusts would then become the main severe hazard. Given the increasing potential for severe thunderstorms, a WW issuance will be needed soon. ..Squitieri/Hart.. 05/28/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1047 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR PORTIONS OF WESTERN TEXAS
Mesoscale Discussion 1047 NWS Storm Prediction Center Norman OK 0140 PM CDT Tue May 28 2024 Areas affected...Portions of western Texas Concerning...Severe potential...Tornado Watch likely Valid 281840Z - 282015Z Probability of Watch Issuance...95 percent SUMMARY...The severe threat is increasing across western TX. Supercells capable of all severe hazards are expected, and a Tornado Watch will be issued soon. DISCUSSION...Convective initiation is underway ahead of the dryline across the western TX Panhandle, where convective outflow progressing westward from earlier storms is providing enhanced lift. These storms are developing amid an environment characterized by 8+ C/km mid-level lapse rates, boosting MLCAPE to over 2000 J/kg amid 50+ kts of effective bulk shear. Supercells are expected to evolve through the afternoon, accompanied by large hail (some stones exceeding 2 inches in diameter), along with severe gusts and a few tornadoes. With time, storms may merge into an MCS later this afternoon. Should this occur, severe gusts will become the main threat. A Tornado watch will be issued shortly to address the severe threat. ..Squitieri/Hart.. 05/28/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SJT...LUB...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0259 PM CDT Tue May 28 2024 Valid 282000Z - 291200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER WESTERN TEXAS... ...SUMMARY... Severe storms capable of damaging winds and large hail remain possible over a small part of the upper Texas Coast into southwest Louisiana for a few more hours. Another area of significant severe weather potential will develop across west Texas this afternoon and evening. ...Texas... A severe MCS producing locally significant damaging gusts and large hail continues to move toward the upper TX Coast, and extends into southwest LA as of 20Z. The very moist and unstable air mass ahead of this activity will support damaging winds and periods of hail before moving offshore later this afternoon. Activity may also build southwestward toward the middle TX Coast. For more information on this area see MCD 1049. To the west, a large area of outflow has pushed across much of central Texas, but sufficient PWAT remains to support destabilization through the afternoon as heating occurs. For more information across western TX, see MCDs 1046 1047 1048. ...NE NM into southeast CO and western KS... The air mass continues to destabilize due to heating, with storms beginning to form from Raton to Pueblo. Easterly surface winds below weak westerlies will lengthen hodographs sufficiently to support cells capable of large hail. Storms should generally move very slowly south or east, producing locally severe gusts and large hail. ..Jewell.. 05/28/2024 .PREV DISCUSSION... /ISSUED 1134 AM CDT Tue May 28 2024/ ...Southeast TX/Western LA... A large nocturnal MCS that continues to affect east TX has dramatically changed the overall forecast of severe storms for later today. The leading edge of the MCS will affect southeast TX and southwest LA this afternoon, in a very moist and extremely unstable environment. Sufficient deep-layer shear will promote supercell and bowing structures capable of damaging winds and very large hail until early evening when the primary activity moves offshore. ...West TX... The outflow boundary from the aforementioned MCS has surged westward across TX. A zone of strong heating and locally higher surface dewpoints on the north side of the boundary is expected to result in rapid thunderstorm development by late afternoon. These storms will be in a favorably sheared environment for intense supercells capable of all severe hazards. Activity will persist through much of the evening and spread into west-central TX. ...WI/IL/IN... Scattered afternoon thunderstorms will develop ahead of a shortwave trough over southeast MN. A few of the storms may produce locally gusty winds and hail, but the overall severe threat is expected to remain marginal. ...Outer Banks of NC... A weak surface boundary currently parallels the NC coast, with a very moist and moderately unstable air mass in place. Isolated afternoon thunderstorms are expected along this boundary, with a risk of locally damaging winds or hail in the most intense storms. ...ME... Isolated afternoon thunderstorms are expected to affect central and eastern ME as a shortwave trough moves across the area. Gusty winds and hail will be possible in the strongest cells. Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0259 PM CDT Tue May 28 2024 Valid 282000Z - 291200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS OVER WESTERN TEXAS... ...SUMMARY... Severe storms capable of damaging winds and large hail remain possible over a small part of the upper Texas Coast into southwest Louisiana for a few more hours. Another area of significant severe weather potential will develop across west Texas this afternoon and evening. ...Texas... A severe MCS producing locally significant damaging gusts and large hail continues to move toward the upper TX Coast, and extends into southwest LA as of 20Z. The very moist and unstable air mass ahead of this activity will support damaging winds and periods of hail before moving offshore later this afternoon. Activity may also build southwestward toward the middle TX Coast. For more information on this area see MCD 1049. To the west, a large area of outflow has pushed across much of central Texas, but sufficient PWAT remains to support destabilization through the afternoon as heating occurs. For more information across western TX, see MCDs 1046 1047 1048. ...NE NM into southeast CO and western KS... The air mass continues to destabilize due to heating, with storms beginning to form from Raton to Pueblo. Easterly surface winds below weak westerlies will lengthen hodographs sufficiently to support cells capable of large hail. Storms should generally move very slowly south or east, producing locally severe gusts and large hail. ..Jewell.. 05/28/2024 .PREV DISCUSSION... /ISSUED 1134 AM CDT Tue May 28 2024/ ...Southeast TX/Western LA... A large nocturnal MCS that continues to affect east TX has dramatically changed the overall forecast of severe storms for later today. The leading edge of the MCS will affect southeast TX and southwest LA this afternoon, in a very moist and extremely unstable environment. Sufficient deep-layer shear will promote supercell and bowing structures capable of damaging winds and very large hail until early evening when the primary activity moves offshore. ...West TX... The outflow boundary from the aforementioned MCS has surged westward across TX. A zone of strong heating and locally higher surface dewpoints on the north side of the boundary is expected to result in rapid thunderstorm development by late afternoon. These storms will be in a favorably sheared environment for intense supercells capable of all severe hazards. Activity will persist through much of the evening and spread into west-central TX. ...WI/IL/IN... Scattered afternoon thunderstorms will develop ahead of a shortwave trough over southeast MN. A few of the storms may produce locally gusty winds and hail, but the overall severe threat is expected to remain marginal. ...Outer Banks of NC... A weak surface boundary currently parallels the NC coast, with a very moist and moderately unstable air mass in place. Isolated afternoon thunderstorms are expected along this boundary, with a risk of locally damaging winds or hail in the most intense storms. ...ME... Isolated afternoon thunderstorms are expected to affect central and eastern ME as a shortwave trough moves across the area. Gusty winds and hail will be possible in the strongest cells. Read more
