MD 2055 CONCERNING SEVERE POTENTIAL...TORNADO WATCH LIKELY FOR PORTIONS OF SOUTHERN ALABAMA INTO THE WESTERN FLORIDA PANHANDLE
Mesoscale Discussion 2055 NWS Storm Prediction Center Norman OK 0340 PM CDT Wed Sep 11 2024 Areas affected...portions of southern Alabama into the western Florida Panhandle Concerning...Severe potential...Tornado Watch likely Valid 112040Z - 120015Z Probability of Watch Issuance...80 percent SUMMARY...The tropical-cyclone tornado threat should gradually increase through the remainder of the afternoon. A Tornado Watch will eventually be needed. DISCUSSION...The center of Hurricane Francine continues to translate northeast as it approaches the LA coastline. Extending east-northeast of Francine's center is a zonal rainband, comprised of relatively discrete cells (some possibly transient supercellular). At the moment, these storms are percolating in intensity offshore, where a greater theta-e/buoyant airmass resides. However, this airmass is expected to gradually advect northward/inland with the north-northeastward progression of Francine through the afternoon and evening hours. HDC and MOB VADs show increasing hodograph sizes/curvature, indicating stronger low-level shear become established along the Gulf Coast. As such, a corresponding tornado threat should increase with the more favorable low-level warm-air/moisture advection. A Tornado Watch will eventually be needed. ..Squitieri/Guyer.. 09/11/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...TAE...MOB...LIX...

WW 667 TORNADO LA MS CW 111740Z - 120400Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 667 NWS Storm Prediction Center Norman OK 1240 PM CDT Wed Sep 11 2024 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Southern Louisiana Far Southern Mississippi Coastal Waters * Effective this Wednesday afternoon and evening from 1240 PM until 1100 PM CDT. * Primary threats include... Several tornadoes likely SUMMARY...Hurricane Francine will continue to approach the southern Louisiana coast and move inland as it progresses northeastward across the region through tonight. The potential for tornadoes is expected to increase through the afternoon and early evening. The tornado watch area is approximately along and 70 statute miles north and south of a line from 60 miles west southwest of Houma LA to 40 miles east southeast of Gulfport MS. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU7). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Tornado Watch means conditions are favorable for tornadoes and 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. && AVIATION...Tornadoes and a few severe thunderstorms with hail surface and aloft to 0 inches. Extreme turbulence and surface wind gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 16045. ...Guyer Read more

MD 2054 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF SOUTHERN IDAHO INTO SOUTHWESTERN MONTANA
Mesoscale Discussion 2054 NWS Storm Prediction Center Norman OK 0326 PM CDT Wed Sep 11 2024 Areas affected...Portions of southern Idaho into southwestern Montana Concerning...Severe potential...Watch unlikely Valid 112026Z - 112300Z Probability of Watch Issuance...5 percent SUMMARY...Thunderstorms are expected to increase in coverage and intensity through the afternoon posing a risk of severe hail and wind. The severe threat is expected to be too isolated and marginal to warrant a severe thunderstorm watch. DISCUSSION...A potent shortwave trough evident in water vapor imagery this afternoon is nosing into southwestern Idaho. As a result of the corresponding focused ascent, thunderstorms will continue to increase in coverage and intensity across the area through the afternoon and evening hours. Despite strong forcing for ascent and sufficient shear for supercells and organized storm modes, the moisture and instability are rather modest. Consequently, storms will be relatively high based, which will favor strong evaporative cooling and isolated severe gusts through the evening hours. Additionally, strong outflow winds from these thunderstorms will likely impact existing fires across the region, which may hinder fire suppression/containment efforts. ..Jirak/Guyer.. 09/11/2024 ...Please see www.spc.noaa.gov for graphic product...

MD 2053 CONCERNING TORNADO WATCH 667... FOR PORTIONS OF SOUTHERN AND EASTERN LOUISIANA INTO SOUTHERN MISSISSIPPI
Mesoscale Discussion 2053 NWS Storm Prediction Center Norman OK 0323 PM CDT Wed Sep 11 2024 Areas affected...portions of southern and eastern Louisiana into southern Mississippi Concerning...Tornado Watch 667... Valid 112023Z - 112200Z The severe weather threat for Tornado Watch 667 continues. SUMMARY...The severe threat continues across Tornado Watch 667. A brief tornado or two cannot be ruled out over the next few hours. DISCUSSION...Multiple transient supercells, embedded within the broader rainbands associated with Hurricane Francine, have percolated in intensity and organization over the past few hours across southeast LA and adjacent areas offshore. However, a widespread and persistent rain-shield has limited diurnal heating, with surface temperatures barely exceeding the mid 70s F amid mid 70s F dewpoints. The resultant thermodynamic profiles yields scant buoyancy inland, with MLCAPE limited to 500 J/kg (perhaps less in spots), which is likely tempering tornado potential. Nonetheless, HDC VAD profiler trends show hodographs increasing in size and curvature as vertical wind fields increase in intensity with the approach of Francine's center. As such, a couple of brief tornadoes cannot be ruled out where any longer-lived, sustained supercell structure can traverse a favorable overlapping buoyancy/shear parameter space. ..Squitieri.. 09/11/2024 ...Please see www.spc.noaa.gov for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0343 PM CDT Wed Sep 11 2024 Valid 131200Z - 191200Z Fire weather concerns are generally expected to be on a downward trend during the extended period. Upper-level troughs will be impact portions of the West. Precipitation associated with these troughs should moderate fuels from the Great Basin into the Northwest and northern Rockies. Localized concerns are possible, but overall critical fire weather potential is low and uncertain. ...Portions of southern Great Lakes Region... With the upper-ridge building into the Great Lakes late this week, the expectation is for hot/dry conditions to continue. The remnant circulation of TC Francine is also forecast to move into the mid-Mississippi Valley during the same time frame. Some increase in surface winds is possible as this occurs. Given drying fuels, some fire weather concerns could develop where RH can fall low enough coincident with stronger surface winds. It is uncertain where this overlap will occur, if at all. No highlights will be added. ...Great Basin... Some areas of dry and breezy conditions appear possible as upper troughs swing through the region. However, precipitation is also expected. While local fire weather concerns are possible next week, the overall fire environment is expected to moderate and critical fire weather potential is low. ..Wendt.. 09/11/2024 ...Please see www.spc.noaa.gov/fire for graphic product...
