WW 258 SEVERE TSTM KS MO 010155Z - 010900Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 258 NWS Storm Prediction Center Norman OK 855 PM CDT Sun May 31 2026 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Kansas Western and Central Missouri * Effective this Sunday night and Monday morning from 855 PM until 400 AM 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 possible A tornado or two possible SUMMARY...Severe storms will develop across eastern Kansas into western Missouri the remainder of the evening. Large hail should be the most common risk, but locally damaging wind potential may also develop. Some tornado risk as well, especially along a residual outflow boundary. The severe thunderstorm watch area is approximately along and 50 statute miles north and south of a line from 55 miles east southeast of Knob Noster MO to 35 miles west northwest of Emporia KS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8). 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 257... 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 550. Mean storm motion vector 29020. ...Guyer Read more

Day 2 Convective Outlook CORR 1 NWS Storm Prediction Center Norman OK 0227 AM CDT Mon Jun 01 2026 Valid 021200Z - 031200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN PLAINS... CORRECTED TO ADD WIND PROBABILITY GRAPHIC ...SUMMARY... Thunderstorms with large hail, severe wind gusts and potentially an isolated tornado threat are expected on Tuesday afternoon and evening in parts of the northern Plains. Strong wind gusts and hail will also be possible in parts of the southern and central High Plains. A few severe wind gusts may also occur from southern Georgia into northern and eastern Florida. ...Northern Plains... A mid-level shortwave trough will move northeastward on Tuesday over the top of a moist and unstable airmass located in the northern Plains. At the surface, a south-to-north corridor of low-level moisture will be in place across the Dakotas. Thunderstorms are expected to develop along the western edge of the moist sector during the afternoon, being supported by large-scale ascent associated with the shortwave trough. Storms will likely increase in coverage during the late afternoon and early evening, with multiple small storm clusters moving northeastward across the region. Along and near the axis of low-level moisture, MLCAPE is forecast to increase into the 1500 to 2500 J/kg range by afternoon. Within this moist airmass, the most favorable environment for severe storms is forecast near the mid-level trough in central North Dakota. Forecast soundings around Bismarck at 21Z have 0-6 km shear in the 40 to 45 knot range with 700-500 mb lapse rates near 8 C/km, suggesting that supercells with large hail will be possible. In addition, late afternoon forecast soundings have 0-3 km storm-relative helicity in the 200 to 250 m2/s2 range, which could support an isolated tornado threat. Severe wind gusts would also be possible with any organized clusters that can persist from late afternoon into the evening. ...Southern and Central High Plains... Southwesterly mid-level flow will be in place on Tuesday in the southern and central Plains, over the western edge of the moist sector. Although model forecasts suggest that large-scale forcing will be limited in most areas, some models forecast a corridor of maximized low-level convergence in the afternoon over eastern Colorado and eastern New Mexico. This would support isolated to scattered thunderstorm development, with storms moving east-northeastward across the southern and central High Plains during the afternoon and evening. Forecast soundings to the east of this axis of low-level convergence during the late afternoon have 0-6 km shear in the 20 to 25 knot range with 700-500 mb lapse rates near 8 C/km. This suggests that hail will be possible. Isolated severe wind gusts may also occur, especially if a convective cluster can become somewhat organized during the early to mid evening. ...Northern and Eastern Florida/Southern Georgia... An upper-level trough will move southward into the Southeast on Tuesday, as a cold front advances southward into southern Georgia. Along and to the south of the front, surface dewpoints from the mid 60s to lower 70s F will contribute to the development of moderate instability by afternoon. Within this unstable airmass, low-level lapse rates will become steep during the mid to late afternoon, which may support an isolated wind-damage threat with the stronger multicells. An isolated potential for severe wind gusts will also be possible in the afternoon along sea breeze boundaries near the coast of northern and eastern Florida. ..Broyles.. 06/01/2026 Read more

Thunderstorms with large hail and severe wind gusts will be possible on Wednesday in parts of the northern Plains. Strong wind gusts and hail will also be possible in parts of the central High Plains. ...Northern Plains/Central High Plains... At mid-levels, a shortwave trough is forecast to move across the Northern High Plains on Wednesday, as southwesterly flow remains in place over the Dakotas. At the surface, a cold front is forecast to move eastward into the central Dakotas during the afternoon. Ahead of the front, surface dewpoints in the lower to mid 60s F will contribute to an axis of moderate instability over the eastern Dakotas by mid to late afternoon. Low-level convergence ahead of the front and large-scale ascent associated with the shortwave trough will support scattered thunderstorm development. Multiple small clusters of storms appear likely to move eastward across the instability corridor in the afternoon and evening. Ahead of the front late Wednesday afternoon, forecast soundings from northeast South Dakota into southeastern North Dakota have 0-6 km shear in the 30 to 40 knot range with 700-500 mb lapse rates in the 7 to 7.5 C/km range. This environment is expected to support supercells with large hail. Severe wind gusts will also be possible, mainly with any organized cluster that can persist into the early to mid evening. Further south across the central High Plains, an axis of moderate instability is forecast to be in place by afternoon. Although model forecasts suggest that large-ascent will remain weak, isolated storms could develop in areas where low-level convergence becomes maximized. By late afternoon, forecast soundings in the central High Plains have 0-6 km shear in the 20 to 25 knot range with 0-3 km lapse rates near 8 C/km. This would support an isolated threat for severe wind gusts. Hail will also be possible. ..Broyles.. 06/01/2026 Read more

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0213 AM CDT Mon Jun 01 2026 Valid 031200Z - 041200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE NORTHERN PLAINS... ...SUMMARY... Thunderstorms with large hail and severe wind gusts will be possible on Wednesday in parts of the northern Plains. Strong wind gusts and hail will also be possible in parts of the central High Plains. ...Northern Plains/Central High Plains... At mid-levels, a shortwave trough is forecast to move across the Northern High Plains on Wednesday, as southwesterly flow remains in place over the Dakotas. At the surface, a cold front is forecast to move eastward into the central Dakotas during the afternoon. Ahead of the front, surface dewpoints in the lower to mid 60s F will contribute to an axis of moderate instability over the eastern Dakotas by mid to late afternoon. Low-level convergence ahead of the front and large-scale ascent associated with the shortwave trough will support scattered thunderstorm development. Multiple small clusters of storms appear likely to move eastward across the instability corridor in the afternoon and evening. Ahead of the front late Wednesday afternoon, forecast soundings from northeast South Dakota into southeastern North Dakota have 0-6 km shear in the 30 to 40 knot range with 700-500 mb lapse rates in the 7 to 7.5 C/km range. This environment is expected to support supercells with large hail. Severe wind gusts will also be possible, mainly with any organized cluster that can persist into the early to mid evening. Further south across the central High Plains, an axis of moderate instability is forecast to be in place by afternoon. Although model forecasts suggest that large-ascent will remain weak, isolated storms could develop in areas where low-level convergence becomes maximized. By late afternoon, forecast soundings in the central High Plains have 0-6 km shear in the 20 to 25 knot range with 0-3 km lapse rates near 8 C/km. This would support an isolated threat for severe wind gusts. Hail will also be possible. ..Broyles.. 06/01/2026 Read more

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0125 AM CDT Mon Jun 01 2026 Valid 021200Z - 031200Z ...Synopsis... Fire weather concerns for Tuesday will primarily be associated with dry lightning potential across parts of far eastern Arizona and western New Mexico. A weak upper wave is evident off the Baja CA coast that will migrate east towards the Southwest over the next 24 hours. Weak pressure falls across the interior West will promote eastward low-level moisture transport into the southern Rockies. The western periphery of the moist plume should spread into eastern AZ by Tuesday afternoon with PWAT values on the order of 0.4 to 0.5 inch. While modest, this will provide sufficient buoyancy to support isolated thunderstorms as weak ascent overspreads the region ahead of the approaching wave. A deeply mixed boundary layer and 15-20 knot storm motions will help limit rainfall amounts and support the potential for dry lightning strikes over a region with receptive fine fuels after several days of warm and dry conditions. ..Moore.. 06/01/2026 ...Please see www.spc.noaa.gov/fire for graphic product...
