SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0459 PM CDT Sun Jun 29 2025 Valid 011200Z - 071200Z ...Days 3-4/Tuesday-Wednesday... An increasing fire weather threat is expected across portions of the western U.S. as a mid-level low moves into California. Mid-level moisture and instability north of the low will support isolated to scattered showers and thunderstorms across the northern California into southern Oregon, primarily along and east of the Cascades. A mix of wet/dry thunderstorms will support new ignitions where over available dry fuels. 40-50 knot southerly mid-level flow over a dry/well-mixed boundary layer will support stronger south winds across southern Nevada Day 3/Tuesday. An upper-level short wave and increasing surface pressure gradients will bring enhanced west winds into the Columbia Basin Day 4/Wednesday. The upper-level trough, initial influx of deeper monsoon moisture into the Intermountain West and daytime instability will support isolated dry thunderstorms across the central Utah Mountains Day 3/Tuesday, with expanding thunderstorm coverage heading into Day 4/Wednesday to include western Wyoming/far southeastern Idaho as well as east-central Nevada. ...Days 5-8/Thursday-Sunday... Another mid-level short wave and associated stronger mid-level flow entering the western U.S. late in the week will increase fire weather concerns across the Great Basin on Day 6/Friday. Long term ensemble guidance does indicate at least a weak upper-level troughing pattern across the western U.S. but uncertainty remains in specific fire weather impacts in the long term. ..Williams.. 06/29/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

WW 477 SEVERE TSTM WI LM 291830Z - 300200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 477 NWS Storm Prediction Center Norman OK 130 PM CDT Sun Jun 29 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Central and Southern Wisconsin Lake Michigan * Effective this Sunday afternoon and evening from 130 PM until 900 PM CDT. * Primary threats include... Scattered damaging wind gusts to 65 mph possible Isolated large hail events to 1 inch in diameter possible SUMMARY...Thunderstorms are intensifying along a weak cold front across Wisconsin. These storms will spread northeastward across the watch area through the afternoon, posing a risk of locally damaging wind gusts and perhaps hail. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 45 miles southwest of Lonerock WI to 60 miles north northeast of Green Bay WI. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7). 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 1 inch. Extreme turbulence and surface wind gusts to 55 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 24025. ...Hart Read more

MD 1513 CONCERNING SEVERE THUNDERSTORM WATCH 478... FOR SOUTHEAST KANSAS...SOUTHWEST MISSOURI...AND FAR NORTHEAST OKLAHOMA
Mesoscale Discussion 1513 NWS Storm Prediction Center Norman OK 0337 PM CDT Sun Jun 29 2025 Areas affected...southeast Kansas...southwest Missouri...and far northeast Oklahoma Concerning...Severe Thunderstorm Watch 478... Valid 292037Z - 292200Z The severe weather threat for Severe Thunderstorm Watch 478 continues. SUMMARY...Thunderstorms will continue through the afternoon. Isolated wind damage should be the primary threat. DISCUSSION...Thunderstorms continue to develop/loosely organize across southeast Kansas and southwest Missouri this afternoon along the leading edge of an advancing cold pool from overnight convection. The airmass along and ahead of these storms is strongly to extremely unstable, with MUCAPE values in excess of 5000 J/kg across northeast Oklahoma and northwest Arkansas, with very little convective inhibition remaining. The degree of instability and loose organization should continue a severe threat through the afternoon despite the presence of meager deep-layer shear. The extreme instability, and precipitable water values near 2 inches in the vicinity of these thunderstorms should lead to continued water-loaded downdrafts and a reinforcement of the cold pool, leading to continued thunderstorm development. An isolated severe wind gust or wind damage will be possible this afternoon, especially on or near area lakes where frictional effects will be minimized. ..Marsh.. 06/29/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1512 CONCERNING SEVERE THUNDERSTORM WATCH 477... FOR PORTIONS OF WISCONSIN
Mesoscale Discussion 1512 NWS Storm Prediction Center Norman OK 0322 PM CDT Sun Jun 29 2025 Areas affected...Portions of Wisconsin Concerning...Severe Thunderstorm Watch 477... Valid 292022Z - 292145Z The severe weather threat for Severe Thunderstorm Watch 477 continues. SUMMARY...Thunderstorms will continue this afternoon in a strongly unstable airmass. Large hail and isolated wind damage are possible with the strongest thunderstorms. DISCUSSION...Thunderstorms continue along a diffuse frontal zone across Wisconsin this afternoon in response to strong diurnal heating and minimal inhibition. Despite most-unstable CAPE values in excess of 2000 J/kg, these thunderstorms have shown little organization nor longevity -- likely owing to the weak deep-layer shear. Given the degree of instability, freezing heights are sufficiently low to support an isolated large hail threat through the afternoon, especially with the strongest thunderstorm cores. Additionally, the potential for isolated wind damage may occur with any strong thunderstorm updraft collapse. ..Marsh.. 06/29/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1511 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHEAST CO AND NORTHEAST NM
Mesoscale Discussion 1511 NWS Storm Prediction Center Norman OK 0300 PM CDT Sun Jun 29 2025 Areas affected...southeast CO and northeast NM Concerning...Severe potential...Watch unlikely Valid 292000Z - 292130Z Probability of Watch Issuance...20 percent SUMMARY...Isolated severe gusts and small to marginally severe hail will be possible through late afternoon across southeast Colorado into northeast New Mexico. After coordination with WFO PUB, watch issuance in the near-term is unlikely, but may increase later towards the Kansas border. DISCUSSION...Several cells have formed from the Pikes Peak region southward along the Sangre de Cristo Mountains. Much of this region lies on the fringe of meager buoyancy with a deep, well-mixed boundary layer across the adjacent High Plains. PUB VWP data sampled slightly stronger low-level northeasterlies relative to mid-level westerlies, indicative of the modest deep-layer flow and shear environment. Nevertheless, the large surface temperature-dew point spreads will be favorable for microbursts capable of strong to severe gusts. Convection is expected to remain disorganized over the next few hours. There is signal that some uptick may occur into early evening as outflows impinge on increasingly greater buoyancy towards the KS border. ..Grams/Hart.. 06/29/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1510 CONCERNING SEVERE POTENTIAL...SEVERE THUNDERSTORM WATCH LIKELY FOR NORTHEAST CO...NORTHWEST KS...FAR SOUTHWEST NE
Mesoscale Discussion 1510 NWS Storm Prediction Center Norman OK 0152 PM CDT Sun Jun 29 2025 Areas affected...northeast CO...northwest KS...far southwest NE Concerning...Severe potential...Severe Thunderstorm Watch likely Valid 291852Z - 292045Z Probability of Watch Issuance...80 percent SUMMARY...Initially isolated severe wind/hail threats are anticipated along the I-25 corridor in Colorado. A slow-moving QLCS, with an increasing wind threat, should evolve eastward across northeast Colorado into northwest Kansas this evening. DISCUSSION...Persistent surface northeasterlies are aiding in the advection of 50s dew points westward towards the Foothills north of the Palmer Divide. This will aid in increasing convective development off the higher terrain and across the I-25 corridor into the adjacent High Plains through this evening. Mid-level westerlies are weak to modest, but sufficient for transient mid-level rotation amid substantial veering of the wind profile with height. This type of flow regime should support outflow-dominated convection. Colliding outflows and amalgamating cells will likely yield a slow-moving MCS as they shift east towards the KS border. As this occurs, a mix of severe wind/hail may transition to primarily a severe gust threat. ..Grams/Hart.. 06/29/2025 ...Please see www.spc.noaa.gov for graphic product...

Mesoscale Discussion 1509 NWS Storm Prediction Center Norman OK 0128 PM CDT Sun Jun 29 2025 Areas affected...eastern WY...the NE Panhandle ...southwest SD Concerning...Severe potential...Severe Thunderstorm Watch likely Valid 291828Z - 292030Z Probability of Watch Issuance...95 percent SUMMARY...At least isolated large hail and severe gusts are likely, with scattered coverage possible by late afternoon. A Severe Thunderstorm Watch issuance is expected. DISCUSSION...Initial, lower-topped convection has formed across far southeast MT towards the Black Hills. This activity is expected to strengthen over the next couple hours amid modest MLCAPE near 1000 J/kg and effective bulk shear around 40 kts. While the parameter space is a step-down from yesterday, which should mitigate overall intensity, the coverage of storms should be greater by peak heating. Additional storms should develop within the weak upslope flow regime across southeast WY. Both areas may eventually converge in the NE Panhandle to far southwest SD vicinity by early evening. A few supercells with large hail are most likely in the northern regime surrounding the Black Hills. Severe gusts may be the primary hazard farther south where multicell clustering dominates. ..Grams/Hart.. 06/29/2025 ...Please see www.spc.noaa.gov for graphic product...
