SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0456 PM CDT Sat Aug 09 2025 Valid 111200Z - 171200Z An upper-level ridge over the Southwest will shift westward and build across much of the West by D3/Monday. An upper-level trough will eject across the Pacific Northwest D4/Tuesday into D5/Wednesday, bringing an increase to winds amid dry conditions. Monsoonal moisture may return northward across portions of Arizona late in the extended with lingering isolated dry thunderstorm chances before a shift to more wetting rainfall potential. ...Dry Thunderstorms... Afternoon thunderstorms are expected along the fringes of the deeper monsoonal moisture in northern Arizona along the Mogollon Rim. PWs will be around 0.75" with mean storm motion around 15-20 kts. Soundings show inverted V profiles with very dry surface conditions. Given the storm motion and dry low-level profiles, storms will likely produce little wetting rainfall. A 10% area was added with this outlook to cover this potential. Thunderstorm potential may extend into portions of the next week, with a gradual increase in moisture northward as the western high shifts into the Four Corners region through the weekend. This may lead to an increase in wetting rainfall, with less potential for dry thunderstorms. ...Wind/RH... Elevated to critical conditions may arise next week (D4/Tuesday-D6/Thursday) for portions of the Pacific Northwest and northern Great Basin, as a trough moves inland and enhanced westerly flow overspreads the region. However, considerable spread exists among medium-range guidance regarding the timing/placement/magnitude of this trough, precluding the introduction of any highlights at this time. ..Thornton.. 08/09/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

WW 581 SEVERE TSTM CO KS NE 091955Z - 100300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 581 NWS Storm Prediction Center Norman OK 155 PM MDT Sat Aug 9 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Northeast Colorado Northwest Kansas Southwest Nebraska * Effective this Saturday afternoon and evening from 155 PM until 900 PM MDT. * Primary threats include... Scattered large hail likely with isolated very large hail events to 3 inches in diameter possible Scattered damaging wind gusts to 70 mph possible A tornado or two possible SUMMARY...Thunderstorms will increase in coverage and intensity through the afternoon in a moist and very unstable environment. A few supercells capable of very large hail and eventually damaging winds are expected across the watch area. The severe thunderstorm watch area is approximately along and 50 statute miles east and west of a line from 40 miles south of Limon CO to 65 miles north of Imperial NE. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU1). 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 3 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 27030. ...Hart Read more

MD 1914 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF FAR NORTHEAST MISSOURI INTO FAR SOUTHEASTERN IOWA AND CENTRAL INTO NORTHERN ILLINOIS
Mesoscale Discussion 1914 NWS Storm Prediction Center Norman OK 0254 PM CDT Sat Aug 09 2025 Areas affected...portions of far northeast Missouri into far southeastern Iowa and central into northern Illinois Concerning...Severe potential...Watch possible Valid 091954Z - 092130Z Probability of Watch Issuance...40 percent SUMMARY...A few damaging gusts may occur with the stronger storms that manage to mature and sustain themselves. DISCUSSION...Multiple thunderstorms are developing along the eastern fringes of a primary confluence band and ahead of a surface cold front, where ample heating is underway. Surface temperatures are approaching 90 F in many places, and given low 70s F dewpoints, MLCAPE is exceeding 3000 J/kg on a widespread basis. Deep-layer forcing and shear are lagging well to the west of the free warm sector, prompting great uncertainty in the overall coverage and intensity of storms into question. Still, ample buoyancy in place will promote wet downburst and damaging gust potential with any storms that can become organized. Therefore, convective trends will continue to be monitored for the need of a Severe Thunderstorm Watch, should storms become more abundant and organized. ..Squitieri/Hart.. 08/09/2025 ...Please see www.spc.noaa.gov for graphic product...

MD 1913 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR EASTERN COLORADO...WESTERN KANSAS...AND FAR SOUTHWEST NEBRASKA
Mesoscale Discussion 1913 NWS Storm Prediction Center Norman OK 0153 PM CDT Sat Aug 09 2025 Areas affected...Eastern Colorado...Western Kansas...and far southwest Nebraska Concerning...Severe potential...Watch likely Valid 091853Z - 092130Z Probability of Watch Issuance...80 percent SUMMARY...Multiple rounds of severe thunderstorms will be possible across portions of the area this afternoon into the overnight. Large hail and damaging winds are the most likely hazards, but tornadoes cannot be ruled out. A watch is likely later this afternoon. DISCUSSION...Southeasterly low-level flow has maintained dewpoints from the mid-50Fs to low 60Fs this afternoon across southeast Colorado, in the presence of strong diurnal mixing. The result is most-unstable CAPE values in excess of 2500 J/kg across portions of the area. At the same time, modest westerly 500mb flow a top this southeasterly low-level flow has maintained deep-layer shear values between 30 and 45 knots. This has set the stage for one or more rounds of thunderstorms this afternoon into the overnight. Expectations are for thunderstorms to initiate within the next couple of hours in the vicinity of the Palmer Divide. There are a couple of different areas where initiation might occur first -- within the Denver cyclone or along the Palmer Divide itself where continued upslope flow is sufficient to overcome convective inhibition. Additional areas of convective initiation could occur across portions of the Nebraska panhandle where convergence is increasing along a residual low-level boundary. The overall wind field will be supportive of discrete convective modes, including supercells, capable of all hazards, although high LCLs may limit the tornado potential somewhat. Additional thunderstorms will be possible later this evening into the overnight across the higher terrain west of the initial convection as moist outflow boundaries move west into the mountains and large-scale ascent increases in response to an approaching short-wave trough. The main threat with these storms would be large hail and damaging winds. Given the possibility for multiple rounds of severe thunderstorms anticipated, one or more watches will likely be needed later today. ..Marsh/Hart.. 08/09/2025 ...Please see www.spc.noaa.gov for graphic product...
