Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0756 PM CDT Sun Jul 06 2025 Valid 070100Z - 071200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE HIGH PLAINS... ...SUMMARY... Scattered storms capable of producing severe wind gusts and large hail will continue tonight across the Plains, especially across eastern Colorado and western parts of Nebraska and Kansas into Oklahoma. ...Discussion... Primary severe risk for the remainder of the night will be focused across the Great Plains, and the central High Plains in particular. Severe potential will continue to nocturnally wane across the Midwest, Maine, and across North Carolina in association with Tropical Depression Chantal. This evening, scattered severe storms including some supercells will persist in areas spanning near the Black Hills southward into the Nebraska Panhandle, eastern Colorado, and western Kansas. One or more semi-organized generally southeastward-moving clusters may eventually evolve within/across the instability axis across far eastern Colorado/western Kansas with an increased severe-wind potential aside from a continued episodic large hail risk. This scenario will be supported by a modestly increasing southerly low-level jet. Damaging winds and some hail will also continue to be a concern across northern Oklahoma with a couple of ongoing clusters, at least for a few hours this evening. ..Guyer.. 07/07/2025 Read more

MD 1585 CONCERNING SEVERE THUNDERSTORM WATCH 489... FOR PARTS OF EAST-CENTRAL COLORADO
Mesoscale Discussion 1585 NWS Storm Prediction Center Norman OK 0654 PM CDT Sun Jul 06 2025 Areas affected...Parts of east-central Colorado Concerning...Severe Thunderstorm Watch 489... Valid 062354Z - 070100Z The severe weather threat for Severe Thunderstorm Watch 489 continues. SUMMARY...Large hail and severe wind gusts remain possible along and east of the I-35 corridor in Colorado -- within Severe Thunderstorm Watch 489. A local southward extension of the watch may be warranted. DISCUSSION...A couple organized clusters/supercells are tracking slowly southeastward along and east of the I-35 corridor in CO, with a recent report of 2-inch hail. VWP and mesoanalysis data show a long/straight hodograph (around 40 kt of effective shear), which combined with steep deep-layer lapse rates, should support the maintenance of these storms with southeastward extent. Large hail and severe wind gusts are the primary concerns. It is possible that the southern supercell tracks south-southeastward out of Severe Thunderstorm Watch 489, and a local extension of the watch may be warranted here. ..Weinman.. 07/06/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 489 SEVERE TSTM CO NE WY 061920Z - 070200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 489 NWS Storm Prediction Center Norman OK 120 PM MDT Sun Jul 6 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northeast Colorado Nebraska Panhandle Southeast Wyoming * Effective this Sunday afternoon and evening from 120 PM until 800 PM MDT. * Primary threats include... Scattered damaging winds and isolated significant gusts to 75 mph likely Scattered large hail likely with isolated very large hail events to 2 inches in diameter possible SUMMARY...Thunderstorms will intensify through the afternoon off the foothills of northeast Colorado and southeast Wyoming. A few severe storms are expected, capable of large hail and damaging wind gusts through the early evening. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 15 miles east northeast of Torrington WY to 50 miles south southeast of Limon CO. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU9). 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 inches. Extreme turbulence and surface wind gusts to 65 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 27030. ...Hart Read more

MD 1584 CONCERNING SEVERE THUNDERSTORM WATCH 489...490... FOR NORTHEAST COLORADO...NORTHWEST KS...AND SOUTHWEST NEBRASKA
Mesoscale Discussion 1584 NWS Storm Prediction Center Norman OK 0603 PM CDT Sun Jul 06 2025 Areas affected...Northeast Colorado...northwest KS...and southwest Nebraska Concerning...Severe Thunderstorm Watch 489...490... Valid 062303Z - 070030Z The severe weather threat for Severe Thunderstorm Watch 489, 490 continues. SUMMARY...A focused/favorable corridor for large hail and severe wind gusts is evident over the central High Plains for the next few hours -- within Severe Thunderstorm Watches 489/490. DISCUSSION...An intense, nearly stationary supercell has evolved out of a cluster of storms over far northeastern CO. Farther west, a separate cluster of storms is showing signs of upscale growth. To the southeast of this activity, a gradually stalling outflow boundary is arcing northwestward from northwest KS into northeastern CO. This outflow boundary may provide a focused mesoscale corridor for the maintenance of the supercell (and additional nearby convection) with southeastward extent into this evening. Along this corridor, around 40 kt of effective shear (locally boosted/enhanced along the boundary) and moderate surface-based instability will favor large to very large hail (some 2+ inches in diameter) and severe wind gusts with any established supercells/clusters. Some upscale growth may also occur with time, as the western cluster may have a tendency of merging with the downstream storms/supercells -- posing an increasing risk of severe-wind gusts into this evening. ..Weinman.. 07/06/2025 ...Please see www.spc.noaa.gov for graphic product...
