WW 720 TORNADO FL CW 101615Z - 102200Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 720 NWS Storm Prediction Center Norman OK 1115 AM EST Sun Dec 10 2023 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Northern Florida Coastal Waters * Effective this Sunday morning and afternoon from 1115 AM until 500 PM EST. * Primary threats include... A couple tornadoes possible Isolated damaging wind gusts to 65 mph possible SUMMARY...Severe storms with a damaging wind and tornado risk, at least on an isolated basis, are expected to continue across parts of northern Florida through the afternoon. The tornado watch area is approximately along and 55 statute miles east and west of a line from 70 miles north of Cross City FL to 45 miles west southwest of Ocala FL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU0). 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 1 inch. Extreme turbulence and surface wind gusts to 55 knots. A few cumulonimbi with maximum tops to 500. Mean storm motion vector 25030. ...Guyer Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0244 PM CST Sun Dec 10 2023 Valid 121200Z - 181200Z Fire weather potential appears low through the extended period. Long-range ensemble guidance continues to show a strong signal for the development and maintenance of an unseasonably strong surface high across the eastern two-thirds of the country for much of the upcoming work week and into next weekend. This will favor cool conditions and weak gradient winds with low probability for widespread sustained winds over 20 mph. An upper disturbance approaching the Southwest/southern High Plains may support areas of breezy conditions around mid-week, but increasing rain chances should limit fire weather concerns. An offshore flow regime is likely late D3/Tuesday into D5/Thursday along the southern CA coast as the aforementioned upper wave shifts into the Southwest. However, long-range ensembles continue to show only a modest signal for strong low to mid-level winds, which limits confidence in the magnitude of the offshore flow regime. While localized fire weather concerns are possible, confidence remains too low to introduce highlights. ..Moore.. 12/10/2023 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

MD 2326 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF EASTERN NC...NORTHEASTERN SC...AND SOUTHEAST VA
Mesoscale Discussion 2326 NWS Storm Prediction Center Norman OK 1205 PM CST Sun Dec 10 2023 Areas affected...Portions of eastern NC...northeastern SC...and southeast VA Concerning...Severe potential...Watch possible Valid 101805Z - 102030Z Probability of Watch Issuance...60 percent SUMMARY...Monitoring portions of eastern NC, northeastern SC, and southeastern VA for a gradual increase in severe-storm potential this afternoon. DISCUSSION...Latest radar data across portions of eastern NC, northeastern SC, and the coastal waters indicates northward-moving clusters of mainly disorganized storms. This activity is likely being driven by low/midlevel warm advection and coastal convergence amid strong low-level south-southwesterly flow (per MHX/LTX VWP data). Through the afternoon, continued boundary-layer positive theta-e advection should destabilize the coastal air mass amid filtered diurnal heating in cloud breaks. The increasing surface-based instability (albeit weak), coupled with strengthening low/deep-layer shear -- characterized by increasingly large clockwise-turning low-level hodographs -- will favor a gradual increase in severe-storm potential through the afternoon. A couple tornadoes and damaging winds will be the main concerns. ..Weinman/Guyer.. 12/10/2023 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...AKQ...MHX...RAH...ILM...

MD 2327 CONCERNING TORNADO WATCH 720... FOR PARTS OF NORTH FL
Mesoscale Discussion 2327 NWS Storm Prediction Center Norman OK 1244 PM CST Sun Dec 10 2023 Areas affected...Parts of north FL Concerning...Tornado Watch 720... Valid 101844Z - 102015Z The severe weather threat for Tornado Watch 720 continues. SUMMARY...Some uptick in the severe threat is possible this afternoon, including the potential for locally damaging wind and a brief tornado or two. DISCUSSION...The northern portion of an extensive QLCS is moving across the northern FL Peninsula early this afternoon. The inland portion of this QLCS has recently remained subsevere, but some diurnal heating and steepening of low-level lapse rates through the afternoon may support an uptick in damaging-wind potential as the line continues to move eastward, especially as a stronger line segment noted west-northwest of Tampa eventually moves onshore. Also, some increase in low-level flow/shear is expected with time, in response to a shortwave trough quickly approaching the area from the west. This may support some threat for a brief, line-embedded tornado or two later this afternoon. Some local expansion of the watch may be needed later this afternoon, depending on the evolution of offshore convection and also the line segment currently noted west of Jacksonville. ..Dean/Guyer.. 12/10/2023 ...Please see www.spc.noaa.gov for graphic product...
