MD 0517 CONCERNING TORNADO WATCH 133... FOR SOUTHWESTERN NEBRASKA...NORTHWESTERN KANSAS
Mesoscale Discussion 0517 NWS Storm Prediction Center Norman OK 0748 PM CDT Thu Apr 25 2024 Areas affected...southwestern Nebraska...northwestern Kansas Concerning...Tornado Watch 133... Valid 260048Z - 260145Z The severe weather threat for Tornado Watch 133 continues. SUMMARY...Storms have diminished in coverage and intensity over the past hour, but severe threat will continue locally. DISCUSSION...Latest composite radar loop over the central High Plains region shows a decrease in convective coverage and intensity over the past hour -- especially along the western Kansas dryline. The main area of convective persistence is ongoing from northeastern Colorado eastward across southwestern Nebraska and northwestern Kansas. The northwest-to-southeast surface baroclinic zone across western Kansas has been making gradual progress southwestward over the past couple of hours -- in part due to convective outflow reinforcement. As such, convection shifting northeastward across the tornado watch continues to encounter a less-unstable environment. As a result, storms have undergone a weakening trend, particularly a decrease in the number of storms with supercellular characteristics. With that said, local/all-hazards risk continues with stronger storms in/near the WW. Additionally, some CAM runs suggest that as the low-level jet increases this evening, likely contributing to an increase in storm coverage on the cool side of the front, some potential for upscale growth into a bowing line is possible, potentially shifting eastward either side of the Nebraska/Kansas border. This could yield a minor increase in wind potential, though the stable boundary layer with eastward extent should limit overall risk. ..Goss.. 04/26/2024 ...Please see www.spc.noaa.gov for graphic product...

WW 134 TORNADO CO KS OK TX 252200Z - 260500Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 134 NWS Storm Prediction Center Norman OK 500 PM CDT Thu Apr 25 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Southeastern Colorado Western Kansas Oklahoma Panhandle Northern Texas Panhandle * Effective this Thursday afternoon from 500 PM until Midnight CDT. * Primary threats include... A few tornadoes and a couple intense tornadoes possible Scattered large hail and isolated very large hail events to 3 inches in diameter likely Scattered damaging winds and isolated significant gusts to 75 mph possible SUMMARY...Isolated to scattered thunderstorms are expected to evolve out of a belt of convection now building along a slow-moving dryline, from near the CO/KS line southward into the northern TX Panhandle. A few supercells may evolve out of this activity with an early threat for large to very large hail and severe gusts. Tornado potential would ramp up from late afternoon into evening with any remaining supercell(s) as low-level shear increases. The tornado watch area is approximately along and 50 statute miles east and west of a line from 45 miles east southeast of Dalhart TX to 55 miles north of Garden City KS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU4). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and 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. && OTHER WATCH INFORMATION...CONTINUE...WW 133... AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 3 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 550. Mean storm motion vector 23025. ...Edwards Read more

Mesoscale Discussion 0515 NWS Storm Prediction Center Norman OK 0542 PM CDT Thu Apr 25 2024 Areas affected...(northeastern Colorado...southwestern Nebraska...and northwestern Kansas Concerning...Tornado Watch 133... Valid 252242Z - 260045Z The severe weather threat for Tornado Watch 133 continues. SUMMARY...Severe/local tornado risk continues within WW 133, across northwestern Kansas, northeastern Colorado, and southwestern Nebraska early this evening. DISCUSSION...Latest radar loop shows numerous strong/severe storms developing from just southeast of GLD southward across western Kansas (into Tornado Watch 134), near and ahead of a dryline analyzed over far eastern Colorado. Meanwhile, additional strong/severe storms are ongoing from near the surface low over northeastern Colorado, east-southeastward across southwestern Nebraska and adjacent northwestern Kansas -- to the cool side of a warm front bisecting Kansas from northwest to southeast. An axis of moderate instability (2000 to 3000 J/kg mixed-layer CAPE) is indicated across the warm sector, bounded by the dryline on the west, and the warm front on the northeast. South-southeasterly low-level flow across this area (veering to east-southeasterly north of the warm front) beneath mid-level south-southwesterlies near 50 kt, is yielding favorable shear for rotating storms -- confirming radar observations. Storms moving north-northeastward out of northwestern Kansas into southwestern Nebraska should weaken with time, as they move into a more stable airmass north of the warm front. Meanwhile, storms nearer the front, and southward along the dryline, will remain capable of producing very large hail (up to around baseball size) and locally damaging wind gusts. Tornado risk also remains evident, and should increase this evening as a south-southeasterly low-level jet ramps up to in excess of 50 kt with time. ..Goss.. 04/25/2024 ...Please see www.spc.noaa.gov for graphic product...

DISCUSSION...Clouds hampered heating for much of the day from the South Plains into most of the TX Panhandle, but boundary layer mixing continues with decreasing clouds. High-based cumulus have formed within the warmer, deeply mixed air mass just west of the dryline, with signs of increasing warm sector cumulus as well. Special midday soundings from AMA and DDC show steep lapse rates aloft and strong mid and high level winds. While dewpoints have dropped in some areas such as western KS, GPS water vapor sensors indicate greater overall moisture content roughly from AMA southeastward toward CDS. Given continued cloud erosion, mixing along the dryline, and an increasing low-level jet into the evening, isolated severe storms cannot be ruled out within this narrow north-south zone. ..Jewell/Hart.. 04/25/2024 ...Please see www.spc.noaa.gov for graphic product...

Very large hail is likely, along with a few tornadoes and damaging gusts. DISCUSSION...Strong heating persists across the region, now on both sides of a stationary front extending from northeast CO into northwest KS. Southeasterly surface winds have brought 50s F dewpoints westward into CO, which is contributing to up to 2000 J/kg MUCAPE within the narrow moist plume. Moderate southwest flow aloft atop the backed low-level southeasterlies is further aiding shear near the boundary which strongly favors long-lived severe storms. Supercells or bows will be possible producing very large hail, a few tornadoes and damaging gusts. ..Jewell/Hart.. 04/25/2024 ...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 0421 PM CDT Thu Apr 25 2024 Valid 271200Z - 031200Z A strong mid-level trough will be present across the Southwest CONUS at the beginning of the period. This trough will shift into the Upper Midwest on Sunday/Monday. Beyond Monday a more zonal pattern should lead to relatively benign fire weather conditions for the day 4-8 period. ...Day 3/Sat - Southern High Plains... A very strong mid-level jet streak will round the base of the mid-upper level trough and eject across the southern High Plains Saturday afternoon. A deeply mixed airmass is present across this region which will allow for some of this stronger flow to mix to the surface. In addition, a developing lee cyclone and the associated tightening of the surface pressure gradient will also aid in stronger winds at the surface. Relative humidity is expected to be around 8 to 12 percent with surface sustained winds around 25 to 35 mph. While this technically meets the criteria for extremely critical fire weather conditions, it does not appear fuels are quite to the extremely critical fuel dryness needed to support true extremely critical fire weather. However, conditions will be monitored for this higher end potential. ...Day 4/Sunday - Southern High Plains... Some dry and breezy conditions are possible in the southern High Plains again on Sunday. These conditions should be mostly confined to southeast New Mexico and vicinity where stronger mid-level flow should be present and at least some weak lee cyclogenesis is possible with a passing weak mid-level shortwave trough. ..Bentley.. 04/25/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
