WW 70 TORNADO FL GA CW 161730Z - 170000Z
URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 70 NWS Storm Prediction Center Norman OK 130 PM EDT Mon Mar 16 2026 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of North Florida Extreme southeast Georgia Coastal Waters * Effective this Monday afternoon and evening from 130 PM until 800 PM EDT. * Primary threats include... A couple tornadoes possible Scattered damaging wind gusts to 70 mph possible Isolated large hail events to 1 inch in diameter possible SUMMARY...New storms are forming in the warm sector across north Florida, and a separate band of storms over the northeast Gulf will move inland through the afternoon. The storm environment favors the potential for a couple of tornadoes with embedded circulations and supercells ahead of the line, as well as occasional damaging gusts (60-70 mph) and isolated large hail near 1 inch in diameter. The tornado watch area is approximately along and 45 statute miles east and west of a line from 35 miles east northeast of Brunswick GA to 80 miles southwest of Ocala FL. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU0). PRECAUTIONARY/PREPAREDNESS ACTIONS...

SPC 2000Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0253 PM CDT Mon Mar 16 2026 Valid 162000Z - 171200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE EASTERN SEABOARD... ...SUMMARY... Scattered severe storms with damaging winds and a few strong tornadoes are expected this afternoon and evening from the Carolinas into the Mid-Atlantic States. ...20Z Update... A couple of changes have been made to the outlook for this issuance. The first change is to remove the Moderate Risk area. Numerous storms have developed early this afternoon along and near the instability axis from the eastern Carolinas northward into the Mid-Atlantic. As a result, instability has remained weaker than was expected, and severe threat coverage should be a bit less than was previously forecast. The second change to the outlook is to remove severe threat probabilities and thunder to the west of the instability corridor from the Florida Panhandle northward into parts of the southern and central Appalachians. ..Broyles.. 03/16/2026 .PREV DISCUSSION... /ISSUED 1128 AM CDT Mon Mar 16 2026/ ...Carolinas to the Mid-Atlantic/Northeast... Large-scale outflow from ongoing broken linear bands along with a separate swath of convection with the low-level warm conveyor have greatly hampered the amplitude of diurnal destabilization across the Carolinas to the DE Valley. Primary severe threat should remain with the pre-frontal linear bands as they spread east-northeast this afternoon. Some intensification may yet occur across eastern SC/southern NC within pockets of low 70s surface temperatures. See MCDs 272-273 for additional storm-term discussion. Farther north, a pre-frontal low-topped convective line is evolving across central PA. This should be the primary driver of afternoon severe potential northeastward into parts of NY as mid 50s to low 60s surface dew points remain prevalent just ahead of this line. Within a deeply meridional wind profile, damaging winds and embedded tornadoes will be the main hazards. This activity should remain spatially confined by a lack of downstream boundary-layer destabilization over eastern NY into New England. In the wake of this leading activity, a second round of low-topped convection will likely reform east of the Blue Ridge into the Piedmont towards late afternoon/early evening. Prior overturning and persistent cloud coverage should mitigate appreciable boundary-layer destabilization. However, robust large-scale ascent and intensifying lower-level winds will accompany the ejection of a 100+ kt 500-mb jetlet within the basal shortwave trough. This should yield a renewed threat for damaging winds accompanying the fast-moving line. Even with meager buoyancy, another round of sporadic severe gusts should occur from NC/VA to the Chesapeake Bay/DE Valley vicinity through this evening. ...GA/FL... Moderate buoyancy characterized by MLCAPE of 1500-2500 J/kg will persist through the afternoon ahead of southwest/northeast-oriented convection. With large-scale ascent, outside of low-level convergence, becoming more focused to the north of this region, there is uncertainty on how far south an organized line will persist in the FL Peninsula. Primary severe threat should remain through mid-afternoon, with a generalized waning in southern extent this evening. Read more

URGENT - IMMEDIATE BROADCAST REQUESTED Tornado Watch Number 67 NWS Storm Prediction Center Norman OK 1050 AM EDT Mon Mar 16 2026 The NWS Storm Prediction Center has issued a * Tornado Watch for portions of District Of Columbia Maryland Northeast North Carolina Eastern Virginia The eastern West Virginia Panhandle Coastal Waters * Effective this Monday morning and evening from 1050 AM until 700 PM EDT. * Primary threats include... A few tornadoes likely with a couple intense tornadoes possible Widespread damaging winds and isolated significant gusts to 85 mph likely Isolated large hail events to 1 inch in diameter possible SUMMARY...Several bands and clusters of storms are expected to intensify through the afternoon, with the potential to produce swaths of damaging winds, some significant (75-85 mph), and embedded circulations will pose a threat for several tornadoes, some of which could be strong (EF2+).

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0134 PM CDT Mon Mar 16 2026 Valid 171200Z - 181200Z The Elevated area over the southern Plains was adjusted slightly eastward to align with the latest forecast guidance. Locally critical conditions will be possible over portions of the Texas Panhandle and southwestern Oklahoma during the Day 2/Tuesday time frame. Additionally, this lack of moisture recovery will effectively extend the burn period and pre-condition fuels prior to the arrival of the strongest synoptic winds on Day 2/Tuesday afternoon. Farther west and north, an additional Elevated fire weather area has been introduced across north-central New Mexico, the eastern Colorado plains, and adjacent segments of the central High Plains. This region will experience sustained west-to-northwest winds near 15-20 mph with RHs of 15-20%. While northern portions of this risk area may struggle to meet strict RH thresholds, the proximity to the upper-level jet suggests these areas will see the highest wind magnitudes, likely compensating for the marginal humidity. ..Stearns/Williams.. 03/16/2026 .PREV DISCUSSION... /ISSUED 0148 AM CDT Mon Mar 16 2026/ ...Synopsis... A period of Elevated fire weather concerns will return on D2/Tuesday across the southern Plains. Westerly flow aloft will overspread the northern/central Rockies, with lee troughing strengthening across the northern/central High Plains. Strengthening southwest winds will extend into the Southern Plains where a residual dry air mass will promote an increasing fire weather threat for southeastern NM, west TX and western OK. Afternoon relative humidity reductions to 15-20% will overlap sustained south southwesterly winds 10-15 mph. A corridor of near Critical to Critical conditions may be possible within this broader Elevated. For now, confidence in coverage of critical winds is too low to include an area at this time, given low combined probabilities from ensemble guidance from the HREF. ...Please see www.spc.noaa.gov/fire for graphic product...

MD 0275 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF SOUTHERN AND CENTRAL FLORIDA
Mesoscale Discussion 0275 NWS Storm Prediction Center Norman OK 1258 PM CDT Mon Mar 16 2026 Areas affected...portions of southern and central Florida Concerning...Severe potential...Watch unlikely Valid 161758Z - 161900Z Probability of Watch Issuance...20 percent SUMMARY...Scattered thunderstorms have developed, and will likely increase in coverage over parts of southern and central FL this afternoon. The severe risk with this initial round is uncertain, though sufficient buoyancy exist for isolated damaging gusts and hail. DISCUSSION...As of 1745 UTC, regional radar and satellite observations showed intensifying thunderstorms along a pre-frontal confluence axis across central FL, and along the sea breeze front in the eastern peninsula. Ahead of the QLCS associated with the upstream cold front, these storms have begun to mature, within a warm and unstable air mass (2000-2500 J/kg MLCAPE). Strong updrafts are present and likely to continue. However, vertical shear is modest currently, with much of central and southern FL displaced from the stronger mid-level flow to the northwest. Thus, these initial storms have shown little in the way of organization so far. Isolated hail will be possible given the degree of buoyancy. Isolated damaging gusts are also possible, especially with storms that cluster and can develop stronger cold pools. The QLCS upstream will likely continue across the eastern Gulf and move onto the peninsula later this afternoon into the evening. Some severe potential may persist with that. However, as large-scale ascent shifts away to the north, the QLCS may weaken overnight. Thus, some severe potential is apparent this afternoon, and later this evening, but confidence in either scenario necessitating a watch is low. Conditions will continue to be monitored. ..Lyons/Thompson.. 03/16/2026 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MFL...MLB...KEY...TBW...

Valid 161800Z - 161930Z The severe weather threat for Tornado Watch 67, 69 continues. SUMMARY...The greatest severe threat within watch 67 and the northern portion of watch 69 will be across southeast Virginia and northeast North Carolina over the next few hours. DISCUSSION...Within a broader environment that has been mostly convectively overturned, a more favorable zone remains across northeast North Carolina and southeast Virginia. Temperatures are in the upper 60s to low 70s with dewpoints in the mid 60s. This yields around 500-750 J/kg MLCAPE per SPC mesoanalysis. The AKQ VWP shows around 55 knots of deep-layer shear with mid-level flow continuing to strengthen through the afternoon. With somewhat more favorable thermodynamics in this zone, a few supercells capable of damaging wind gusts and perhaps a tornado or two are possible. ..Bentley/Thompson.. 03/16/2026 ...Please see www.spc.noaa.gov for graphic product...
