WW 645 SEVERE TSTM MT 232055Z - 240300Z
URGENT - IMMEDIATE BROADCAST REQUESTED Severe Thunderstorm Watch Number 645 NWS Storm Prediction Center Norman OK 255 PM MDT Fri Aug 23 2024 The NWS Storm Prediction Center has issued a * Severe Thunderstorm Watch for portions of Western and Central Montana * Effective this Friday afternoon and evening from 255 PM until 900 PM MDT. * Primary threats include... Isolated significant damaging wind gusts to 75 mph possible SUMMARY...Scattered thunderstorms will continue to develop and move north-northeastward across the region through early evening, with severe-caliber wind gusts a possibility. The severe thunderstorm watch area is approximately along and 95 statute miles east and west of a line from 25 miles north of Cut Bank MT to 40 miles south of Dillon MT. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU5). 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 65 knots. A few cumulonimbi with maximum tops to 450. Mean storm motion vector 20030. ...Guyer Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0500 PM CDT Fri Aug 23 2024 Valid 251200Z - 311200Z A large-scale trough will advance eastward across the northern Rockies on Day 3/Sunday. Preceding the trough, moderate deep-layer southwesterly flow will overspread a deep/dry boundary layer across WY -- favoring dry and breezy conditions. Given modestly receptive fuels, elevated to locally critical conditions are expected. Additionally, a mix of wet/dry thunderstorms, aided by ascent accompanying the trough, will develop across portions of the northern Rockies on Day 3/Sunday. While this will pose some risk for lightning-induced fire-starts, the threat appears too localized/marginal for Isolated Dry Thunderstorm probabilities at this time. Thereafter, surface high pressure will build across the West, in the wake of the aforementioned large-scale trough. This will temporarily reduce surface winds and fire-weather concerns across much of the West. On Day 5/Tuesday, a midlevel trough/low and related strong westerly flow will cross the Pacific Northwest. This will promote dry/breezy conditions across portions of the Northwest into the northern Rockies. However, considerable disagreement among the medium-range guidance regarding the strength of surface winds casts uncertainty on the overall threat -- precluding Critical probabilities at this time. These dry/breezy conditions should spread eastward across the northern Rockies on Day 6/Wednesday, with similar uncertainty regarding the development of critical conditions. ..Weinman.. 08/23/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

MD 1978 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF WESTERN AND CENTRAL MONTANA
Mesoscale Discussion 1978 NWS Storm Prediction Center Norman OK 0313 PM CDT Fri Aug 23 2024 Areas affected...portions of western and central Montana Concerning...Severe potential...Watch possible Valid 232013Z - 232215Z Probability of Watch Issuance...60 percent SUMMARY...Thunderstorms will increase in coverage and intensity over the next few hours across western and central Montana. Isolated damaging gust of 55-70 mph are possible, along with a few instances of hail to near one inch diameter. DISCUSSION...Gradual destabilization is occurring over the MCD area as temperatures have warmed into the 80s F this afternoon. Boundary-layer moisture will remain meager, but steep midlevel lapse rates/cool temperatures aloft will support MLCAPE increasing to around 500-1000 J/kg through early evening. Deepening cumulus is noted over the mountains and thunderstorms are expected to increase in coverage over the next couple of hours as stronger ascent overspreads the region. Favorable vertical shear will support organized updrafts/clusters, while dry low-levels and very steep low-level lapse rates support strong/severe gusts. Elongated/straight hodographs in conjunction with favorable midlevel instability/shear will also support isolated marginally severe hail with more intense/longer-lived updrafts. While some MLCIN remains over the region, additional heating and increasing ascent should gradually erode inhibition, but overall poor vertical moisture profiles will limit instability. Nevertheless, a severe thunderstorm watch may become necessary, especially if convection across southwest MT/eastern ID sufficiently organizes into forward propagating clusters with time as this activity shifts north/northeast. ..Leitman/Guyer.. 08/23/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1977 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR SOUTHEASTERN ARIZONA AND FAR SOUTHWESTERN NEW MEXICO
Mesoscale Discussion 1977 NWS Storm Prediction Center Norman OK 0222 PM CDT Fri Aug 23 2024 Areas affected...Southeastern Arizona and far southwestern New Mexico Concerning...Severe potential...Watch unlikely Valid 231922Z - 232115Z Probability of Watch Issuance...5 percent SUMMARY...Severe wind gusts and isolated large hail will be possible as storm coverage increases this afternoon. A watch is not expected. DISCUSSION...With a moist airmass (upper 50s to low 60s F dewpoints) being heated into the mid/upper 90s F, storms have initiated earlier than most guidance had suggested. Currently, objective mesoanalysis suggests between 1000-1500 J/kg MLCAPE is present. Vertical shear, however, is quite weak under the influence of the upper ridge. The primary hazard will likely be severe wind gusts, particularly as additional heating should tend to mix dewpoints out to some extent. The strongest storms could also produce marginally severe hail as they peak in intensity. ..Wendt/Guyer.. 08/23/2024 ...Please see www.spc.noaa.gov for graphic product...
