MD 1337 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PARTS OF THE TEXAS SOUTH PLAINS AND PANHANDLE INTO FAR SOUTHWEST OKLAHOMA
Mesoscale Discussion 1337 NWS Storm Prediction Center Norman OK 0544 PM CDT Tue Jun 17 2025 Areas affected...Parts of the Texas South Plains and Panhandle into far southwest Oklahoma Concerning...Severe potential...Watch possible Valid 172244Z - 180045Z Probability of Watch Issuance...40 percent SUMMARY...Severe wind gusts will likely accompany any high-based thunderstorms that can initiate. Storm development/coverage is uncertain, though trends are being monitored for a possible watch. DISCUSSION...Visible satellite imagery shows increasingly agitated high-based cumulus developing along a dryline extending across the TX South Plains. Radar data from LBB also shows continued attempts at convective initiation within the zone of low-level ascent. If a couple storms can develop within this corridor, a deeply mixed boundary layer (characterized by an inverted-V sounding) and sufficient instability would promote severe downbursts (and possibly some severe hail) with any sustained high-based storms. Storm development/sustenance and overall coverage is somewhat uncertain, though trends are being monitored for a possible watch. ..Weinman/Mosier.. 06/17/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1338 CONCERNING TORNADO WATCH 429... FOR PARTS OF THE EASTERN OK/TX PANHANDLES INTO FAR NORTHWEST OK
Mesoscale Discussion 1338 NWS Storm Prediction Center Norman OK 0605 PM CDT Tue Jun 17 2025 Areas affected...Parts of the eastern OK/TX Panhandles into far northwest OK Concerning...Tornado Watch 429... Valid 172305Z - 180000Z The severe weather threat for Tornado Watch 429 continues. SUMMARY...Intensification of an ongoing discrete supercell is possible as it continues southeastward over the next couple hours -- with an associated risk of supercell tornadoes. DISCUSSION...A discrete supercell has developed over the OK Panhandle, within a localized zone of surface convergence. Strongly unstable inflow for this storm and large streamwise vorticity (250-300 m2/s2 effective SRH) will support the intensification of this storm as it tracks southeastward over the next couple hours. If this occurs, supercell tornadoes and large hail will both be concerns. ..Weinman.. 06/17/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...OUN...AMA...

MD 1336 CONCERNING SEVERE THUNDERSTORM WATCH 428... FOR CENTRAL HIGH PLAINS
Mesoscale Discussion 1336 NWS Storm Prediction Center Norman OK 0516 PM CDT Tue Jun 17 2025 Areas affected...Central High Plains Concerning...Severe Thunderstorm Watch 428... Valid 172216Z - 172345Z The severe weather threat for Severe Thunderstorm Watch 428 continues. SUMMARY...Damaging winds may accompany convection as it spreads southeast this evening. It's not entirely clear whether a new WW will be warranted downstream across eastern Colorado into western Kansas. DISCUSSION...Water-vapor imagery depicts a well-defined short-wave trough ejecting east-southeast across eastern WY/northeast CO. Scattered strong/severe convection has developed ahead of this feature, especially across the central High Plains where an MCS is maturing. Latest radar imagery suggests a gradually expanding precip shield over northeast CO into southwest NE. The leading edge of this activity is likely generating near-severe wind gusts, but the downstream air mass has not fully recovered from earlier convective overturning. Large-scale support favors this MCS propagating across the remainder of northeast CO toward northwest KS and there is some concern the organized nature of this cluster will continue to produce locally severe winds. It's not clear whether a new severe thunderstorm watch will be issued, but it under consideration. ..Darrow.. 06/17/2025 ...Please see www.spc.noaa.gov for graphic product...

URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 430 NWS Storm Prediction Center Norman OK 605 PM CDT Tue Jun 17 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Southwest Oklahoma Texas South Plains into Northwest Texas * Effective this Tuesday evening from 605 PM until 1100 PM CDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...Thunderstorm development is anticipated across the Texas South Plains this afternoon. High storm bases and a deeply mixed boundary layer suggest that some of these storms could produce strong outflow capable of strong/severe gusts. Isolated hail is possible as well, particularly with the early-stage development. The severe thunderstorm watch area is approximately along and 45 statute miles north and south of a line from 15 miles west of Lubbock TX to 40 miles east northeast of Altus OK. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU0). PRECAUTIONARY/PREPAREDNESS ACTIONS...

MD 1335 CONCERNING TORNADO WATCH 429... FOR PARTS OF SOUTH-CENTRAL KANSAS INTO FAR NORTH-CENTRAL OKLAHOMA
Mesoscale Discussion 1335 NWS Storm Prediction Center Norman OK 0443 PM CDT Tue Jun 17 2025 Areas affected...Parts of south-central Kansas into far north-central Oklahoma Concerning...Tornado Watch 429... Valid 172143Z - 172315Z The severe weather threat for Tornado Watch 429 continues. SUMMARY...Parts of south-central Kansas is the most favorable corridor for a couple supercell tornadoes during the next couple hours -- within Tornado Watch 429. DISCUSSION...A semi-discrete supercell is evolving just north of a remnant outflow boundary intersection over far south-central KS this afternoon. Along and north of the boundary, an earlier sheltered boundary layer (with backed easterly surface winds) has destabilized substantially, with temperatures in the lower/middle 80s amid upper 60s/lower 70s dewpoints. This strongly unstable surface-based air, combined with around 50 kt of effective shear, will favor intensification of the ongoing supercell and additional cells that develop on its flanks. Additionally, a large clockwise-curved hodograph (200-250 m2/s2 0-1 km SRH) per earlier VWP data and mesoanalysis will support a couple supercell tornadoes with any sustained supercells in this corridor over the next couple hours. ..Weinman.. 06/17/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0451 PM CDT Tue Jun 17 2025 Valid 191200Z - 251200Z ...Day 3-4/Thursday-Friday... An upper-level trough will begin to enter the Pacific Northwest Day 3/Thursday while upper-level ridging shifts eastward into the Plains. Increased mid-level flow atop a dry/well-mixed boundary layer will bring an expansive fire weather threat much of the Great Basin and Colorado Plateau in the form of breezy southwest winds and low relative humidity. A mid-level wind maxima rounding the southern periphery of an upper-level low then pushing into the Pacific Northwest will support even stronger southwest winds of 20-30 mph (locally higher in favored downslope regions) across much of central/southern Utah, northern Arizona and far western Colorado as well as northwestern Nevada where fuels have become increasingly supportive of wildfire spread. 70 percent probability of Critical fire weather conditions have been maintained and expanded within these areas. ...Day 5-8/Saturday-Tuesday... The warm, dry and breezy conditions supportive of wildfire growth in dry fuels will shift southeastward towards the upper Colorado River Basin and northern Arizona by the weekend. Magnitude of winds will wane by early next week as mid-level flow relaxes and shifts northeastward. However, the combination of increasingly dry fuels, drought and lack of rainfall will support an ongoing fire weather threat through Day 8/Tuesday across much of southeastern Utah, northern Arizona and far western Colorado. ...California Central Valley... Dry, post-frontal northerly flow along with low relative humidity and cured grasses will support at least an Elevated fire weather threat on Day 5/Saturday across the Central Valley. ..Williams.. 06/17/2025 ...Please see www.spc.noaa.gov/fire for graphic product...
