SPC Day 3-8 Fire Weather Outlook
SPC Day 3-8 Fire Weather OutlookDay 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0335 PM CST Tue Nov 12 2024 Valid 141200Z - 201200Z Upper-level troughing is expected over both the East and West Coasts Day 3/Thursday - Day 5/Saturday, with upper-level ridging slowly shifting from over the central US to over portions of the eastern US. There is forecast uncertainty regarding how this amplified upper-level pattern progresses early next week, which will have ramifications for potential fire weather concerns in southern/central California and the Northeast. ...Northeast and Mid-Atlantic... An approaching warm front with associated cloud cover and possible shower activity will limit fire weather concerns across the Mid-Atlantic and into portions of the Northeast on Day 3/Thursday. However, dry/breezy conditions are likely to develop across portions of the Mid-Atlantic and Northeast Day 4/Friday - Day 6/Saturday. Given the recent drought, lack of forecast rain, and near to record high fire danger, 40% probabilities were expanded and introduced during what appears to be a multi-day fire weather episode. Some forecast uncertainty remains regarding forecast precipitation and where the greatest overlap of elevated/critical winds/RH will be, but confidence is increasing in at least elevated fire weather conditions for portions of New Jersey, eastern Pennsylvania, the Hudson Valley/vicinity, and southern New England late this week through the weekend. ...Southern/central California... Breezy/gusty north-northwest winds are possible in portions of central/southern California Day 5/Saturday into Day 7/Monday as multiple cold fronts sweep south and east over the region. The southern extent of forecast precipitation and the magnitude of these winds remain uncertain precluding 40% areas at this time. Confidence is increasing in an offshore/Santa Ana wind event mid-next week, which is on the edge of the outlook period. This event may start on Day 8/Tuesday and last multiple days. This will be monitored and if trends hold, probabilities will likely be added in subsequent extended outlooks. ..Nauslar.. 11/12/2024 ...Please see www.spc.noaa.gov/fire for graphic product...Read more

SPC Nov 12, 2024 2000 UTC Day 1 Convective Outlook
SPC 2000Z Day 1 OutlookDay 1 Convective Outlook NWS Storm Prediction Center Norman OK 0158 PM CST Tue Nov 12 2024 Valid 122000Z - 131200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF THE SOUTHERN HIGH PLAINS... ...SUMMARY... Isolated strong to severe thunderstorms may impact parts of the Texas South Plains and Oklahoma/Texas Panhandle vicinity into far southwestern Kansas this evening, possibly accompanied by some risk for hail and gusty winds. ...20Z Update... The primary change to this outlook was to expand Marginal Risk probabilities northward into portions of far southwestern KS. Here, guidance consensus depicts 700-1000 J/kg MUCAPE amid elongated hodographs, which may support an instance or two of marginally severe hail with the more persistent, discrete updrafts that can form. Otherwise, the previous forecast (see below) remains on track. ..Squitieri.. 11/12/2024 .PREV DISCUSSION... /ISSUED 1024 AM CST Tue Nov 12 2024/ ...Southern High Plains... An upper-level trough over the eastern Great Basin/Four Corners at midday will continue eastward toward the south-central High Plains tonight. Gradual lee-side cyclogenesis will occur particularly late today into tonight, with a sharpening southern High Plains dryline/lee trough, with an eastward-moving Pacific cold front that will overtake the dryline/lee trough from west-to-east tonight. Modest-caliber low-level moisture return will occur north-northwestward across the southern High Plains, with surface dewpoints tending to remain limited to the upper 40s/lower 50s F into this evening. It still appears likely that deep convective potential across northwest Texas and the Oklahoma/Texas Panhandles will remain limited through peak heating, owing to the moisture limitations and a persistent capping inversion. Isolated thunderstorm development will become more probable after sunset as lift associated with a strengthening low-level jet increases, and as the surface cold front overtakes the lee trough. While MUCAPE is expected to remain rather weak (generally 500-1000 J/kg or less), strong deep-layer shear will support organized updrafts with any sustained convection. Isolated hail appears to be the main threat, as thunderstorms should have a tendency to remain slightly elevated. But, some chance for strong/gusty winds may also exist. The window for severe hail should remain small in space and time this evening, as convection will likely grow upscale fairly quickly. Even so, small hail may occur farther north/east into parts of Kansas and Oklahoma overnight into early Wednesday morning.Read more
SPC Nov 12, 2024 1930 UTC Day 3 Severe Thunderstorm Outlook
SPC 1930Z Day 3 OutlookDay 3 Convective Outlook NWS Storm Prediction Center Norman OK 0113 PM CST Tue Nov 12 2024 Valid 141200Z - 151200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe thunderstorms are not currently expected on Thursday. ...Synopsis... A negatively titled shortwave trough is forecast to extend from the Upper Midwest into the southern Appalachians early Thursday morning. This trough is expected to lose amplitude as it continues eastward while also developing a closed mid-level circulation. This resulting cyclone will then likely progress across the Upper OH Valley and into the Mid-Atlantic by early Friday. In response to this evolution, surface cyclogenesis is anticipated off the Carolina coast, or perhaps just inland over the coastal Carolinas. Farther west, the overall upper pattern will amplify as ridging builds across the Plains and troughing deepens along the West Coast. ...Central/Northeast Gulf Coast vicinity... Showers and thunderstorms will likely be ongoing over the central Gulf Coast early Thursday morning, as a cold front pushes eastward through moist and modestly buoyant warm sector in place across the region. Northern extent of this warm sector is expected to become increasingly confined throughout the day with the cooler, more continental airmass over the Carolinas and Mid-Atlantic remaining place. A strong storm or two is possible within this warm sector, particularly Thursday morning from southwest/southern AL into the western FL Panhandle, but limited buoyancy and weakening shear should keep any severe threat isolated, precluding the need for any severe probabilities with this outlook. ...Coastal Carolinas... Uncertainty regarding the strength and location of the surface low expected to deepen over the region late Thursday night/early Friday morning limits the confidence on how far inland any favorable low-level moisture/buoyancy would penetrate. Current guidance suggests there could be a confined area along the warm front near the northern NC Coast where there is enough overlap between modest buoyancy and strong shear to support some severe potential. Given the limited spatial extent of this region and the general uncertainty regarding the overall pattern, no severe probabilities were introduced with this outlook. However, a small area maybe needed in future outlooks if forecast confidence increases. ..Mosier.. 11/12/2024Read more

A marginal tornado/wind threat is apparent on Wednesday afternoon into Wednesday night across a part of the central Gulf Coast States. Thunderstorms with strong to locally severe gusts are also possible near the immediate coasts of Washington, Oregon, and northern California. ...Synopsis... A shortwave trough is forecast to move from the Plains through the MS Valley on Wednesday, becoming more negatively tilted as it does. An occluded surface low associated with this system will begin the period over the mid MO Valley before moving eastward across IA and reaching the northern IL early Thursday morning. More consequently for the severe-weather potential, a secondary triple-point low is expected to progress eastward across the northern portion of the Southeast states, along the northern edge of an eastward-evolving warm sector. Cold front associated with this low will gradually move eastward across the Southeast states during the day. Farther west, an upper-level trough is forecast to progress farther inland across the western CONUS, as an embedded shortwave trough moves across northern CA into the interior Northwest/northern Great Basin. ...Lower Mississippi Valley/Central Gulf Coast... General expectation is for a triple-point surface low to evolve over the Mid-South vicinity through the early afternoon as low-level moisture continues to advect northward across the central Gulf Coast region. Dewpoints in the upper 60s/low 70s are anticipated ahead of this low and associated cold front. The airmass is expected to destabilize amid this low-level moisture, but overall buoyancy will still be modest given the lack of steep lapse rates. The combination of destabilization and increasing ascent is forecast to result in thunderstorm development across the warm sector, but along and ahead of the eastward-progressing cold front. The stronger shear will likely be displaced north of the stronger buoyancy, but enough shear is expected across the warm sector to support organized storms if updrafts can persist and deepen. This evolution could support a few marginal supercells and/or stronger clusters during the afternoon and evening, with a threat of locally damaging winds and possibly a tornado or two. Elevated storms will also be possible through the day/evening to the north of the richer surface moisture. While effective shear will be sufficient for a few strong elevated storms, the severe potential with northward extent will tend to be limited by weak midlevel lapse rates and generally marginal buoyancy. ...WA/OR/Northern CA coasts... Cold mid-level temperatures (i.e. -24 to -28 deg C at 500 mb) associated with the upper trough are expected to spread eastward throughout the day. These cold mid-level temperatures and associated steep mid-level lapse rates will contribute to modest buoyancy along the coastal portions of the Pacific Northwest. Highest storm coverage is anticipated over the northern CA coast vicinity from the late morning into the early afternoon along as the frontal band moves through, but persistent forcing for ascent within this modestly buoyant airmass is expected to result in more cellular storms throughout the remainder of the afternoon and evening. A more linear mode is anticipated within the frontal band, with a few convectively enhanced gusts possible. Low-topped cellular activity is anticipated in the wake of the frontal band, with a few instances of small hail, and potentially even a brief tornado, possible. ..Mosier.. 11/12/2024Read more
