SPC AC 031625 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1125 AM CDT Sat Jun 03 2023 Valid 031630Z - 041200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS LOWER RIO GRANDE VALLEY IN SOUTH TX... ...SUMMARY... A swath of severe wind gusts may occur between about 8 PM to Midnight CDT along a portion of the Lower Rio Grande Valley. Otherwise, isolated severe thunderstorms with wind and hail will be possible across parts of the south-central and northeastern states, mainly through this evening. ...Far eastern NM to south TX... An elongated, low-amplitude upper trough will stay anchored from the Great Basin to the southern High Plains through tonight. The attendant belt of moderate mid-level westerlies will largely remain confined across northern Mexico into Deep South TX. Several areas of isolated to scattered thunderstorm development are expected later this afternoon into the evening: 1) the higher terrain of northern Coahuila into perhaps the Big Bend, 2) a remnant outflow boundary over the Concho Valley, and 3) the far eastern NM/west TX border area from the Raton Mesa to the Permian Basin. Areas to the north of south TX will be in a more modest deep-layer shear environment with effective values around 20-30 kt. This should generally support weak and transient mid-level updraft rotation and multicell clustering. Owing to continued steep mid-level lapse rates, large hail and severe wind gusts will be possible with overall coverage expected to remain isolated. A relatively greater but largely conditional severe threat may occur over a portion of the Rio Grande Valley in south TX later this evening if supercell clusters over Coahuila can develop an adequate cold pool prior to the nocturnal increase in MLCIN. The 14Z HRRR is the most insistent of morning CAMs with its depiction of an MCS moving east of the international border. Guidance is fairly consistent that negative low-level theta-e advection will shift west from the northwest Gulf across Deep South TX tonight, likely yielding weakening of convection as it spreads farther east of the Rio Grande. ...Mid-Atlantic/Central Appalachians/Upper OH Valley... Isolated to scattered thunderstorms should develop along a west to southwest-moving cold front, with initial development expected in PA based on a swelling cu field already. A pocket of moderate buoyancy with MLCAPE of 1000-1500 J/kg will similarly form just ahead of this portion of the front. Guidance suggests there may be a belt of somewhat greater north-northeasterly mid-level winds in the eastern PA vicinity. But the lack of a 12Z ALB observed sounding or VWP data high enough to sample this lowers overall confidence. CAM guidance does suggest that a couple of southwest-moving cells that initiate in this region may contain mid-level updraft rotation which could result in a meso-beta corridor of relatively greater hail and wind potential. Elsewhere, weaker deep-layer shear and buoyancy will serve to limit potential to locally strong gusts from sporadic microbursts amid steep low-level lapse rates and a relatively deep mixed boundary layer. ...Ark-La-Tex to south LA... Scattered to widespread thunderstorms are expected later this afternoon within a moderately buoyant and weakly sheared environment. The strongest storms will be capable of locally strong wind gusts. ..Grams/Thornton.. 06/03/2023 CLICK TO GET WUUS01 PTSDY1 PRODUCT NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 2000Z

SPC AC 021556 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1056 AM CDT Fri Jun 02 2023 Valid 021630Z - 031200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS WEST TX... ...SUMMARY... A few tornadoes, destructive baseball to softball sized hail, and scattered severe wind gusts to around 80 mph will be possible across parts of the southern High Plains into this evening. ...Southern High Plains... Large-scale ascent is already underway ahead of a shortwave trough over NM that will slowly shift into west TX through tonight. Stratus is fairly pervasive across most of west TX, outside of the Permian Basin. In this latter area, with mid 60s surface dew points and a pocket of nearly full insolation, convection will likely develop in the next couple hours. With around 8-9 C/km mid-level lapse rates and an elongated nearly straight-line hodograph, splitting discrete supercells are expected with very large to giant hail possible. A couple long-lived supercells may occur as they slowly move southeast along the Lower Pecos Valley through early evening. More widespread thunderstorm activity is expected farther north, initially beginning in southeast NM and then spreading into the South Plains and southern TX Panhandle areas. Relatively larger low-level SRH compared to farther south should support potential for at least a couple tornadoes in addition to significant severe hail, centered on the late afternoon period. Amalgamation of numerous cells should result in upscale growth into an MCS by early evening with a threat for localized significant severe wind gusts. Overall severe threat should wane after sunset into late evening as the MCS spreads deeper into southwest OK through the Big Country. ...Central High Plains to eastern MT... Isolated to scattered thunderstorms will develop along a lee trough later this afternoon in the presence of generally 50s surface dew points. Convection will probably tend to focus near a pair of slow-moving mid-level impulses across eastern CO and eastern MT. For the eastern MT regime in the mid-levels, lapse rates will be weak but compensated by a belt of 25-30 kt southeasterlies. This may be adequate to support transient weak supercell structures. In the eastern CO regime, steep mid-level lapse rates will counter weaknesses in the low to mid-level hodograph. Isolated severe hail and wind will be possible, centered on the late afternoon to early evening. ...New England... Isolated to scattered thunderstorms are expected downstream of a southward-moving shortwave trough approaching from Quebec. Nearly all enhancement to mid/upper flow will be confined to the cool side of a surface cold front pushing south-southwest. 12Z GYX sounding revealed very light winds throughout the troposphere. As such, single-digit effective bulk shear is anticipated across most of the region, with values perhaps into the teens closer to the front. Well-mixed and inverted-v thermodynamic profiles should support locally strong wind gusts in sporadic microbursts during the late afternoon to early evening. ..Grams/Thornton.. 06/02/2023 CLICK TO GET WUUS01 PTSDY1 PRODUCT NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 2000Z

SPC AC 271942 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0242 PM CDT Sat May 27 2023 Valid 272000Z - 281200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM PARTS OF EASTERN NEW MEXICO AND THE SOUTH PLAINS VICINITY OF TEXAS...SOUTH TO THE RIO GRANDE... ...SUMMARY... Isolated to scattered severe thunderstorms appear possible across much of the High Plains this afternoon and evening. Large hail and severe gusts are the primary hazards. ...Discussion... The primary change being implemented with this outlook update is the addition of SLGT risk across the Permian Basin/Transpecos regions of Texas, and into the Big Bend area. Widespread convection is initiating over far West Texas, and southward into adjacent northern Mexico. Continued convective increase is expected, with upscale growth into a loosely organized, linear MCS possible. With a few of the strongest storms within the convective cluster likely to be capable of producing hail/wind near or exceeding severe levels -- as suggested by the pre-storm environment, upgrade to SLGT appears warranted at this time. Otherwise, aside from tweaks to the thunder lines, current areas and outlook reasoning continue to reflect current expectations. ..Goss.. 05/27/2023 .PREV DISCUSSION... /ISSUED 1111 AM CDT Sat May 27 2023/ ...Eastern NM/West TX... An overnight cluster of thunderstorms has resulted in remnant outflow boundary extending from near Plainview TX westward to Santa Rosa NM, with continued slow southward movement. This boundary is likely to maintain some character through the afternoon and play a role in convective activity. The 14Z HRRR solution appears to have a reasonable handle on this scenario, and develops a cluster of supercells by mid-afternoon near the boundary over eastern NM. These storms will track eastward in a corridor of slightly enhanced/backed low-level winds. Large/very large hail and damaging winds are the main threats. However, a tornado or two cannot be ruled out. ...Northern High Plains... Similar to yesterday, full sunshine and steep mid-level lapse rates will lead to scattered afternoon thunderstorms over the higher terrain of CO/WY/MT. These storms will spread across the adjacent high plains through the early evening. Moderate CAPE values will promote strong updrafts capable of isolated large hail and damaging winds. However, the main limiting factor will be rather weak bulk shear. Organized multicell storms will likely be the dominant mode, with some clustering expected through the evening.

SPC AC 161602 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1102 AM CDT Tue May 16 2023 Valid 161630Z - 171200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF SOUTHEAST KENTUCKY...NORTHEAST TENNESSEE...EXTREME SOUTHERN WEST VIRGINIA...WESTERN VIRGINIA...AND FAR NORTHWEST NORTH CAROLINA... ...SUMMARY... Strong to severe thunderstorms, associated with wind damage, isolated large hail and a few tornadoes are expected to develop across parts of the southern and central Appalachians this afternoon into early evening. ...KY/TN to VA/NC Vicinity... A shortwave mid/upper trough will move across the Ohio Valley and Central Appalachians today, and into the Mid-Atlantic by this evening. This feature will allow midlevel flow to increase through the day, with a belt of 40-50 kt westerly flow overspreading western KY/TN to coastal VA/NC. At the surface, a weak low was analyzed over western KY at 15z. A composite warm front/outflow boundary extended eastward from the low across northern/central KY. This will likely demarcate the northern extent of greater severe potential/coverage. A weak surface lee trough is also evident across the VA/NC Piedmont. The surface low should track roughly east/northeast through the day with a trailing cold front spreading across the region this afternoon/evening. Dewpoints in the upper 60s to near 70 F (low/mid 60s with eastward extent to the lee of the Appalachians), and strong heating south of the warm front where mostly clear skies exist, will allow for weak to moderate destabilization. Low-level flow will remain somewhat weak through 1-2 km, but increasing speed with height will result in effective shear magnitudes around 35-45 kt, supporting organized convection. Initial semi-discrete cells are expected, posing a risk for hail and damaging gusts. Steep low-level lapse rates will support strong outflow and convection will likely transition toward bows as storms shift east across the spine of the Appalachians. A swath of strong gusts may persist east of the Appalachians in a moist and unstable downstream environment. While low-level flow will remain weak, modestly enlarged forecast hodographs and some increase in effective SRH suggest a few spin-ups along the eastward-advancing gust front will be possible given a favorable low-level thermodynamic environment. For short term severe potential across KY/TN vicinity, see MCD 800. More than one round of strong/severe thunderstorm activity may be possible across the VA/NC Piedmont. Initial activity associated with the lee trough may pose a hail/wind risk, while any emerging bow/MCS by late afternoon/early evening may also result in a damaging wind risk. ...Northern MS/AL/GA into Upstate SC... This area will remain south of strong midlevel flow, with mainly modestly, mostly unidirectional westerly deep-layer flow forecast. Effective shear around 20-25 kt amid moderate instability will allow for some transient/loosely organized cells. Steep low-level lapse rates will foster strong outflows and a few locally strong/damaging gusts are possible. ...High Plains... A shortwave trough currently over SD will track southward today into the high plains of eastern WY/CO and western NE/KS. Strong heating over this region, coupled with dewpoints in the 40s to lower 50s, will result in a deeply mixed boundary layer and CAPE values of 1000-1500 J/kg. Widely scattered diurnal thunderstorms are expected, with sufficient deep-layer shear for high-based supercell structures capable of gusty winds and hail. ..Leitman/Moore.. 05/16/2023 CLICK TO GET WUUS01 PTSDY1 PRODUCT NOTE: THE NEXT DAY 1 OUTLOOK IS SCHEDULED BY 2000Z
