URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 501 NWS Storm Prediction Center Norman OK 310 PM CDT Thu Jul 10 2025 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Far Western Iowa Northeast Nebraska Extreme Southeast South Dakota * Effective this Thursday afternoon and evening from 310 PM until 1000 PM CDT. * Primary threats include... A couple tornadoes possible Scattered damaging winds and isolated significant gusts to 80 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter likely SUMMARY...Thunderstorm development is anticipated within the very unstable airmass across central/northeast NE this afternoon. Environmental conditions support initial supercells capable of all severe hazards, including large to very large hail and tornadoes. Upscale growth is anticipated after the initial cellular mode, with the resultant convective line progressing quickly eastward. Strong wind gusts are possible within this line, including gusts over 75 mph. The tornado watch area is approximately along and 75 statute miles north and south of a line from 5 miles north northwest of Broken Bow NE to 10 miles east of Denison IA. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). 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. && AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 70 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 27035. ...Mosier Read more

MD 1636 CONCERNING SEVERE THUNDERSTORM WATCH 502... FOR EASTERN COLORADO...WESTERN KANSAS...FAR SOUTHERN NEBRASKA
Mesoscale Discussion 1636 NWS Storm Prediction Center Norman OK 0656 PM CDT Thu Jul 10 2025 Areas affected...eastern Colorado...western Kansas...far southern Nebraska Concerning...Severe Thunderstorm Watch 502... Valid 102356Z - 110200Z The severe weather threat for Severe Thunderstorm Watch 502 continues. SUMMARY...Instances of severe wind and hail remain possible in WW502. DISCUSSION...Several clusters of storms continue across far eastern CO into western KS/NE. Storms are within a region of increasing MLCIN. Above the inversion, elevated instability remains for storms rooted above the surface. Storms are likely elevated and will mainly pose a risk for large hail, though some more surface based storms may produce occasional severe winds, primarily across northeastern Colorado where MLCIN is weaker and deep layer shear around 40-50 kts remains for organization. ..Thornton.. 07/10/2025 ...Please see www.spc.noaa.gov for graphic product...

Valid 102345Z - 110145Z The severe weather threat for Tornado Watch 501 continues. SUMMARY...Severe threat continues across eastern Nebraska into western Iowa. DISCUSSION...Short-wave ridging that has been observed over the lower MO Valley is shifting east as a secondary, notable short-wave trough is advancing across central SD/western NE. Low-level warm advection is focused into this region, just north of a boundary that is draped from south of Grand Island-Omaha-north of Des Moines. This warm-advection regime favors rotation, and a few slow-moving supercells can be expected in advance of the short wave this evening. While some supercell structures are possible, with time convection may evolve into larger clusters, and possibly an MCS. LLJ is forecast to strengthen across northeast KS into southwest IA later this evening, and this should encourage more robust convection to propagate into this portion of the MO Valley with time. ..Darrow.. 07/10/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 502 SEVERE TSTM CO KS NE 102030Z - 110300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 502 NWS Storm Prediction Center Norman OK 230 PM MDT Thu Jul 10 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Colorado Western and Central Kansas Southwest and South-Central Nebraska * Effective this Thursday afternoon and evening from 230 PM until 900 PM MDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph likely Scattered large hail and isolated very large hail events to 2 inches in diameter possible SUMMARY...Thunderstorm coverage is expected to increase across a wide area from the Colorado Front Range into western Kansas and south-central Nebraska this afternoon, with storms continuing into the evening. Some isolated hail is possible with these storms, particularly along the Front Range, but the primary severe hazard is expected to be strong wind gusts. Some wind gusts to 75 mph are possible. The severe thunderstorm watch area is approximately along and 130 statute miles east and west of a line from 25 miles northeast of Imperial NE to 15 miles east southeast of Elkhart KS. 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. && OTHER WATCH INFORMATION...CONTINUE...WW 501... AVIATION...A few severe thunderstorms with hail surface and aloft to 2 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 25025. ...Mosier Read more

MD 1634 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR EASTERN IA INTO NORTHERN ILLINOIS
Mesoscale Discussion 1634 NWS Storm Prediction Center Norman OK 0613 PM CDT Thu Jul 10 2025 Areas affected...Eastern IA into northern Illinois Concerning...Severe potential...Watch unlikely Valid 102313Z - 110115Z Probability of Watch Issuance...20 percent SUMMARY...Isolated hail/wind, and perhaps a brief tornado, are possible across eastern Iowa into northern Illinois this evening. Watch is not currently anticipated. DISCUSSION...Low-amplitude short-wave trough is evident in water-vapor imagery, very near the MS River, from southeast MN into northwestern IL. Large-scale ascent ahead of this feature appears to be aiding convection across northern IL, just north of a warm front that is draped from south of Chicago to north of Dubuque IA. Low-level warm advection is likely contributing to a few small, slow-moving clusters north of the wind shift. Radar data suggests this activity may be generating locally severe hail, and gusty winds. Wind profiles are not that strong ahead of the short wave, but veering profiles do suggest some rotation is possible. Farther west across eastern IA, scattered thunderstorms have developed just behind the trough within a more buoyant and stronger sheared environment. At times a few updrafts have exhibited supercell characteristics, but updrafts have struggled to organize at times, possibly due to the passage of the short wave. Unless this activity becomes more organized current thinking is the primary concerns will be isolated hail/wind, and perhaps a brief tornado. ..Darrow/Hart.. 07/10/2025 ...Please see www.spc.noaa.gov for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0740 PM CDT Thu Jul 10 2025 Valid 110100Z - 111200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS EVENING INTO TONIGHT ACROSS PARTS OF WESTERN/CENTRAL KANSAS....EASTERN NEBRASKA...MUCH OF IOWA...PARTS OF NWRN ILLINOIS... ...SUMMARY... Scattered strong to severe thunderstorm development remains possible this evening across parts of the central Great Plains into Upper Midwest. This could still include a slowly organizing cluster of storms with potential for strong to severe surface gusts across the eastern Nebraska into Iowa vicinity. ...01Z Update... A belt of 20-30+ kt southerly/westerly lower/mid-tropospheric flow across parts of the central Great Plains into portions of the Upper Midwest may continue to enhance convective development, at least a bit, this evening into the overnight hours. In mid-levels, this includes flow augmented by convectively generated cyclonic circulations, but, in lower-levels, this includes a south-southwesterly low-level jet associated with weak mid-level troughing digging east-southeast of the Wyoming/Colorado Rockies. The low-level jet appears to be focusing a corridor of stronger warm advection across parts of south central through eastern Nebraska, where convective development may still consolidate and grow upscale this evening. Perhaps aided by forcing associated with the synoptic perturbation, or another evolving MCV, it might not be out of the question that activity may slowly organize and acquire increasing inflow of seasonably moist boundary-layer air characterized by sizable CAPE as it tends to propagate eastward overnight. If this occurs, there appears potential for sufficient intensification to support an increasing risk for strong to severe surface gusts. ..Kerr.. 07/11/2025 Read more
