SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1249 AM CDT Sun Jul 20 2025 Valid 211200Z - 221200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF NORTHWEST NEVADA... ...Synopsis... The upper-level trough in the Northwest will continue to dig southward through the day on Monday. Some increase in the mid-level jet is expected to occur from northwest Nevada into the northern Rockies. A surface low will deepen in the northern Great Basin. ...Central/northern Great Basin into western Wyoming... A broad area of elevated fire weather conditions are expected across these regions. Surface winds will reach 15-20 mph in most locations, though areas of higher speeds are possible in terrain-favored areas. Single digit RH is possible in parts of central/northern Nevada, but 15-20% will be more common elsewhere. Critical conditions are expected along the Sierra Front in northwest Nevada. Here, the mid-level jet will enhance winds aloft during the afternoon. While the surface low will not be overly deep, the combination of these factors will support winds around 20 mph near the terrain. Gusts to around 30 mph are also possible. There is some potential for high level clouds to limit RH reductions. Even with some of these marginal factors, wind speeds should be sufficient to promote rapid fire spread in fuels that are very dry (ERCs above 90th percentile). ..Wendt.. 07/20/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1248 AM CDT Sun Jul 20 2025 Valid 201200Z - 211200Z ...Synopsis... An upper-level trough will begin to sag into northern California and the northern Great Basin today. A surface trough will develop from the Northwest into the central Great Basin. Elevated to locally critical conditions are possible from northern Nevada into the Snake River Plain and western Wyoming. RH will be lowest in Nevada where 10-20% is expected. Farther north and east, 15-20% will be more common. Surface wind speeds will generally range from 15-20 mph in most locations. With some terrain enhancement in the Snake River Plain, there is some potential for briefly stronger winds. This location has a greater probability for sustained critical conditions, though ensemble guidance continues to suggest it will remain quite localized. ..Wendt.. 07/20/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 1734 CONCERNING SEVERE THUNDERSTORM WATCH 528... FOR SOUTHEAST MONTANA...SOUTHWEST NORTH DAKOTA...WESTERN SOUTH DAKOTA
Mesoscale Discussion 1734 NWS Storm Prediction Center Norman OK 1155 PM CDT Sat Jul 19 2025 Areas affected...Southeast Montana...southwest North Dakota...western South Dakota Concerning...Severe Thunderstorm Watch 528... Valid 200455Z - 200600Z The severe weather threat for Severe Thunderstorm Watch 528 continues. SUMMARY...Isolated thunderstorms will pose a risk for large hail and severe wind gusts through 06z. A local watch extension may be needed for portions of South Dakota beyond the scheduled expiration. DISCUSSION...Isolated severe thunderstorms were located over extreme northwest and southwest SD at 0450z, with a history of large hail and severe gusts. Latest mesoanalysis shows instability continuing to slowly diminish with the onset of nocturnal cooling and prior convective outflows, however there remains some potential for a severe threat to continue across western SD after the scheduled 06z expiration of WW 528. Thus, a local extension in time may be required prior to 06z. ..Bunting.. 07/20/2025 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...UNR...

MD 1731 CONCERNING SEVERE THUNDERSTORM WATCH 529... FOR CENTRAL AND EASTERN NEBRASKA/KANSAS BORDER REGION
Mesoscale Discussion 1731 NWS Storm Prediction Center Norman OK 0910 PM CDT Sat Jul 19 2025 Areas affected...Central and eastern Nebraska/Kansas Border Region Concerning...Severe Thunderstorm Watch 529... Valid 200210Z - 200415Z The severe weather threat for Severe Thunderstorm Watch 529 continues. SUMMARY...Severe/damaging winds are possible along the Nebraska/Kansas border over the next few hours. DISCUSSION...A small bowing segment has developed from an earlier supercell and is moving east just west of Blue Hill. This has shown a stronger wind signal from KUEX velocity data with a small region of 60-70 kts at about 1500 ft. Measured gusts of 60-70 mph have occurred with this storm over the last hour. With the increase in the low-level jet this evening, additional storms have also develop ahead of and to the south of this storm. Severe/damaging winds are the primary hazard this evening, particularly with the storm west of Blue Hill. The downstream environment remains favorable with 40 kts of effective shear and 3500 J/kg of MLCAPE. However, MLCIN is also increasing. Another 2-3 hours of strong to severe storms appear possible. Whether additional watches will be needed into southeast Nebraska/northeast Kansas is not clear. ..Wendt.. 07/20/2025 ...Please see www.spc.noaa.gov for graphic product...

WW 528 SEVERE TSTM MT ND SD WY 192210Z - 200600Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 528 NWS Storm Prediction Center Norman OK 410 PM MDT Sat Jul 19 2025 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Eastern Montana Southwest North Dakota Western South Dakota Northeast Wyoming * Effective this Saturday afternoon from 410 PM until Midnight MDT. * Primary threats include... Scattered large hail and isolated very large hail events to 2.5 inches in diameter possible Scattered damaging wind gusts to 70 mph possible SUMMARY...Thunderstorms are beginning to develop across parts of eastern Montana and northeast Wyoming. This activity will spread east-southeastward through the evening, posing a risk of large hail and damaging wind gusts. The severe thunderstorm watch area is approximately along and 60 statute miles east and west of a line from 55 miles north northeast of Glasgow MT to 30 miles south southeast of Rapid City SD. 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 526...WW 527...

MD 1732 CONCERNING SEVERE THUNDERSTORM WATCH 528... FOR PORTIONS OF EASTERN MONTANA...NORTHEAST WYOMING...SOUTHWEST NORTH DAKOTA...WESTERN SOUTH DAKOTA
Mesoscale Discussion 1732 NWS Storm Prediction Center Norman OK 0911 PM CDT Sat Jul 19 2025 Areas affected...Portions of eastern Montana...northeast Wyoming...southwest North Dakota...western South Dakota Concerning...Severe Thunderstorm Watch 528... Valid 200211Z - 200315Z The severe weather threat for Severe Thunderstorm Watch 528 continues. SUMMARY...The severe weather threat will continue across the watch area, with large to very large hail, and strong/damaging gusts as the primary severe hazards. DISCUSSION...Regional radar composite at 0205z shows three areas of severe thunderstorms across the watch area and in the general vicinity of a northwest-southeast oriented boundary/instability gradient. One area of storms has recently developed/strengthened over northeast MT, where subtle ascent from an embedded shortwave trough continues to contribute to storm development. Severe storms over east-central/southeast MT have begun to evolve into a small cluster, while storms over western SD remain more isolated. The environment across the watch area remains moderately unstable with MLCAPE of 1500-2000 J/kg, and effective shear of 40-50 kts. These storms were also along the eastern periphery of a plume of steeper mid-level lapse rates. Latest hi-res guidance suggests these storms should continue to move generally east across the watch area through 06z and pose a continued risk for large/isolated very large hail with the more discrete cells and damaging gusts. ..Bunting.. 07/20/2025 ...Please see www.spc.noaa.gov for graphic product...
