MD 0527 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR FAR SOUTHWESTERN TEXAS
Mesoscale Discussion 0527 NWS Storm Prediction Center Norman OK 0214 PM CDT Wed Apr 23 2025 Areas affected...far southwestern Texas Concerning...Severe potential...Watch possible Valid 231914Z - 232115Z Probability of Watch Issuance...60 percent SUMMARY...Risk for gusty winds and large hail possible this afternoon. DISCUSSION...Deepening cumulus is observed across the Davis Mountains and ahead of the surface dryline across far western Texas. Temperatures have warmed into the upper 70s to 80s which has led to weakening of MLCIN across the region. Convective initiation should occur in the next 1-2 hours. Ahead of the dryline, MLCAPE around 1000-2000 J/kg with deep layer shear around 35-40 kts. This will support supercells capable of large hail (some very large) and damaging winds, given steep lapse rates around 8-9 C/km. A watch may be needed in the coming hour. ..Thornton/Hart.. 04/23/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...EWX...SJT...MAF...

Mesoscale Discussion 0528 NWS Storm Prediction Center Norman OK 0239 PM CDT Wed Apr 23 2025 Areas affected...parts of wrn KS...sern CO...OK Pnhdl Concerning...Severe potential...Watch likely Valid 231939Z - 232215Z Probability of Watch Issuance...80 percent SUMMARY...Intensifying thunderstorm development appears increasingly probable through the 4-6 PM CDT time frame, including the potential for supercells posing a risk for large hail and tornadoes in a focused area near/southeast of Goodland. DISCUSSION...With daytime heating and mixing, the boundary-layer within surface troughing across the Texas/Oklahoma Panhandle vicinity through western Kansas continues to deepen and destabilize. It now appears generally characterized by surface temperature/dew point spreads in excess of 30 F, with CAPE increasing to 1500-2000+ J/kg. Inhibition is in the process of weakening, and deepening high-based convection is now evident within the axis of stronger destabilization. With further insolation, the initiation of thunderstorms appears increasingly probable, some of which may eventually be accompanied by small hail and localized strong downbursts. Of greater concern is the potential for convective development where better low-level moisture, on the western periphery of outflow associated with persistent ongoing convection across central Kansas, intersects the axis of stronger heating. This appears focused near a weak developing cyclonic circulation southeast of Goodland, where shear associated with clockwise turning of low-level wind fields with height, beneath a belt of 30 kt westerly flow around 500 mb, is likely sufficient for supercells. This is where potential for large hail appears maximized, and near-surface CAPE/upward vertical accelerations may promote the potential for tornadoes. ..Kerr/Hart.. 04/23/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 162 SEVERE TSTM TX 232025Z - 240300ZURGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 162 NWS Storm Prediction Center Norman OK 325 PM CDT Wed Apr 23 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southwest Texas * Effective this Wednesday afternoon and evening from 325 PM until 1000 PM CDT. * Primary threats include... Scattered large hail likely with isolated very large hail events to 2.5 inches in diameter possible Scattered damaging wind gusts to 70 mph likely SUMMARY...Thunderstorms will intensify this afternoon over the Davis Mountains and along a dryline and spread northeastward across the watch area. The strongest storms will pose a risk of large hail and damaging wind gusts. The severe thunderstorm watch area is approximately along and 55 statute miles east and west of a line from 25 miles northeast of Wink TX to 40 miles southwest of Dryden 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. && AVIATION...A few severe thunderstorms with hail surface and aloft to 2.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 26025. ...HartRead more - Wed, 23 Apr 2025 19:58:06 +0000: SPC Apr 23, 2025 2000 UTC Day 1 Convective Outlook - SPC Forecast Products

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0254 PM CDT Wed Apr 23 2025 Valid 232000Z - 241200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN/CENTRAL PLAINS... ...SUMMARY... Scattered strong to severe thunderstorms are forecast over parts of the southern/central Plains today and tonight, with large hail and damaging winds possible. ...20z Update... The previous forecast generally remains on track with only minor adjustments needed. A slight westward expansion of 5% hail/wind probabilities across southeast CO where convective initiation is underway along the Raton Mesa upstream of a moist/unstable environment. A significant hail area has also been introduced for portions of western KS where backed low-level flow within a moderately unstable environment (MLCAPE around 2000 J/kg) should promote robust supercells with an attendant large/very large hail threat. Consideration was given to introducing significant hail/wind areas across parts of southwest TX; however, recent ACARS and RAP forecast soundings show somewhat weaker mid-level winds (15-20 knots) compared to yesterday when significant hail/wind occurred in a similar thermodynamic environment. This, combined with the potential for more limited convective coverage, limits confidence in a sufficiently widespread significant hail/wind threat to warrant additional probabilities. See the previous discussion and recently issued MCDs #527 and #528 for additional details. ..Moore.. 04/23/2025 .PREV DISCUSSION... /ISSUED 1128 AM CDT Wed Apr 23 2025/ ...Central and Southern High Plains... Modest zonal flow pattern persists across the Plains states today, with only weak large scale forcing anticipated. However, strong heating across the High Plains, coupled with circulations along a diffuse dryline and forcing associated with the nocturnal low-level jet will aid in the development of scattered thunderstorms from western KS into the TX Panhandle this afternoon and evening. The area of greatest concentration of storms will likely be over western KS, where model guidance shows greatest confidence in a strengthening low-level jet and some upper support. Storms should develop by late afternoon, with forecast soundings showing sufficient deep-layer shear for supercell structures. Large hail will be the main concern. Low-level moisture will be marginal, but enlarging hodographs by early evening could also support a risk of a few tornadoes. Farther south, thunderstorm coverage will be more widely scattered across the TX Panhandle into the Big Bend region. Nevertheless, steep mid-level lapse rates and sufficient westerly flow aloft will pose a risk of a few supercells capable of large hail and damaging winds through the evening. ...Northeast KS... A small cluster of strong storms has developed this morning over central KS. Several morning CAM solutions suggest an increasing risk of thunderstorm development/intensification by mid-afternoon over northeast KS - in vicinity of a weak surface boundary. While this scenario is unclear, a few of these storms could pose a risk of large hail and gusty/damaging winds. ...Southeast States... Strong daytime heating will aid in destabilization across much of GA/SC this afternoon, with scattered thunderstorm development expected. Winds aloft are weak and storms should be relatively disorganized. However, cool temperatures aloft will aid in a few robust updrafts - posing some risk of hail and gusty winds.
