MD 1818 CONCERNING TORNADO WATCH 594... FOR MUCH OF CENTRAL AND NORTHERN FLORIDA AND INTO SOUTHERN GEORGIA
Mesoscale Discussion 1818 NWS Storm Prediction Center Norman OK 0605 PM CDT Sun Aug 04 2024 Areas affected...much of central and northern Florida and into southern Georgia Concerning...Tornado Watch 594... Valid 042305Z - 050000Z The severe weather threat for Tornado Watch 594 continues. SUMMARY...Isolated/embedded rotating storms within T.S. Debby's convective bands will continue to pose a risk for brief tornadoes this evening and tonight. A new Tornado Watch will be issued within the hour, given the scheduled 05/00 expiration of WW 594. DISCUSSION...Latest radar imagery shows the center of T.S. Debby to be located roughly 60 nautical miles west of KCLW (Clearwater, FL) at this time, and moving slowly northward. Over the past couple of hours, a few cells within the convective bands surrounding Debby have exhibited rotation -- suggestive that some tornado risk persists at this hour. Tornado potential may increase slightly with time, as Debby likely strengthens to a category 1 Hurricane over the next several hours, per expectations laid out in the latest National Hurricane Center forecasts. With Tornado Watch 594 set to expire at 05/00Z, a new tornado watch will be issued covering much of the same region, though not extending as far south as the current watch. ..Goss.. 08/04/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 1817 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR CENTRAL AND EASTERN MONTANA...WESTERN DAKOTAS
Mesoscale Discussion 1817 NWS Storm Prediction Center Norman OK 0507 PM CDT Sun Aug 04 2024 Areas affected...central and eastern Montana...western Dakotas Concerning...Severe potential...Watch possible Valid 042207Z - 050000Z Probability of Watch Issuance...60 percent SUMMARY...Storms capable of damaging wind to increase through the afternoon/evening. DISCUSSION...A shortwave moving eastward across Montana this afternoon will provide forcing for ascent to erode MLCIN and result in thunderstorm development over the next few hours. Across central/eastern Montana, daytime heating has yielded MLCAPE around 1000 J/kg. Surface objective analysis and forecast soundings also show profiles with steep low to mid-level lapse rates, deeply mixed profiles, and large dew point depressions which all favor downward momentum transfer. Deep layer shear 30-40 kts should provide organization for storms to grow upscale and present risk of damaging wind. A watch may be needed in the next couple of hours. ..Thornton/Smith.. 08/04/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...BIS...UNR...BYZ...GGW...RIW...

MD 1816 CONCERNING TORNADO WATCH 594... FOR MUCH OF THE FLORIDA PENINSULA AND FAR SOUTHERN GEORGIA
Mesoscale Discussion 1816 NWS Storm Prediction Center Norman OK 0353 PM CDT Sun Aug 04 2024 Areas affected...much of the Florida Peninsula and far southern Georgia Concerning...Tornado Watch 594... Valid 042053Z - 042300Z The severe weather threat for Tornado Watch 594 continues. SUMMARY...The tornado risk continues across FL and far southern GA. The greatest risk should gradually drift north toward the FL/GA border later this evening. DISCUSSION...As of 2045 UTC, convection associated with the outer bands of TS Debby continues to move across the central and northern FL Peninsula. Periodic updraft rotation has been noted with some of the stronger cells over the last several hours. However, the expanding CDO noted with Debby's outflow has gradually expanded inland, limiting diurnal heating. MLCAPE has started to decrease below 1000 J/kg reducing overall convective intensity of the observed bands. That, in combination with a more linear dominant storm mode, has stifled tornado potential somewhat so far this afternoon. Still, as Debby continues to deepen, already strong low-level shear (TBW VAD 600+ m2/s2 ESRH) should continue to intensify and shift northeast of the center. This will support low-level updraft rotation and the potential for a few tornadoes with any sustained convection. ..Lyons.. 08/04/2024 ...Please see www.spc.noaa.gov for graphic product...

Persons in these areas should be on the lookout for threatening weather conditions and listen for later statements and possible warnings. && AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 0.5 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 14030. ...Hart Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0428 PM CDT Sun Aug 04 2024 Valid 061200Z - 121200Z ...Synopsis... A mid to upper-level shortwave trough will traverse the Pacific Northwest D3/Tuesday atop an upper ridge, while the ridge is shunted south and slightly eastward. The aforementioned shortwave trough will continue to progress eastward into the Great Plains D4/Wednesday, with some narrow bands of modest mid-level flow accompanying it across the northern Great Basin and Rockies. Generally, weaker flow is expected through most of the troposphere after D4/Wednesday across much of the central and western CONUS through D8/Sunday. ...Dry Thunderstorms... Increasing mid-level ascent associated with a shortwave trough will impact the northern and central Rockies D3/Tuesday. Sufficient monsoonal moisture within and on the northern periphery of the upper ridge, above drier boundary layer conditions, will continue to support dry thunderstorm chances over receptive fuels from southwestern MT, southeastward into WY, eastern UT, and western/northwestern CO. PWATs are expected to fall across these regions into D4/Wednesday, although the area of 10 percent Isolated Dry Thunderstorms will become more confined to western CO and eastern UT by then as the main shortwave trough moves into the Northern Great Plains. ...Dry and Windy... Increasing west-northwesterly surface winds will develop D4/Wednesday across the Upper Snake River Plain/southeast ID and Wyoming Basin via a tightening surface pressure gradient, and momentum transfer from aloft under a belt of relatively stronger mid-level flow. While fuels should remain less receptive across southeast ID during this time, hot and dry conditions will combine with these breezier winds across southwest WY where they should remain more receptive. A small 40 percent Critical area has been introduced there. ..Barnes.. 08/04/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
