Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0339 AM CST Wed Jan 01 2025 Valid 041200Z - 091200Z ...DISCUSSION... A shortwave trough is expected to progress from the western Great Basin through the central Rockies and into central/southern Plains on D4/Saturday, continuing eastward across the Mid/Lower MS Valley on D5/Sunday. Surface cyclogenesis is anticipated ahead of this wave over the southern High Plains on D4/Saturday, with the resulting low tracking eastward across OK. Strengthening low-level southerly flow ahead of this low will result in moderate moisture advection, with a warm sector characterized by 60s dewpoints preceding the low and its attendant cold front. Thunderstorms are possible from central TX/OK eastward through the Lower MS Valley on D5/Sunday, as the cold front interacts with the moderately moist and buoyant air within the warm sector. Deep-layer vertical shear is expected to be strong enough to support organized storms (i.e. greater than 40 kt from 0-6 km). Latest deterministic runs of the ECMWF and GFS continued to show notable differences, particularly with the overall speed of the shortwave and its associated surface low. However, EPS and GEFS members shows greater consistency, with numerous members placing the surface low over the AR vicinity by D5/Sunday evening. Consequently, there is increased confidence that the environment over the Lower MS Valley will support severe thunderstorms D5/Sunday afternoon, with the threat potentially continuing into the Southeast overnight. The risk for thunderstorms will likely continue across the Southeast on D6/Monday as this system continues eastward. Cold and dry conditions are anticipated across the entire CONUS on D7/Tuesday and D8/Wednesday. Read more

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0131 AM CST Wed Jan 01 2025 Valid 011200Z - 021200Z ...Synopsis... Elevated fire weather conditions continue across portions of Southern California as a result of persistent weak offshore flow. These elevated conditions will likely be ongoing at the start of the outlook period before surface pressure gradients relax during the day. Wednesday night into Thursday morning, surface pressure gradients will once again increase resulting in an increase in offshore winds and one more night of elevated fire weather conditions. ..Marsh.. 01/01/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0120 AM CST Wed Jan 01 2025 Valid 031200Z - 041200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Friday. ...Synopsis and Discussion... The upper pattern early Friday morning will likely be characterized by western CONUS ridging and central/eastern CONUS troughing. A pair of phased shortwave troughs are forecast to move through the eastern CONUS troughing and off the Mid-Atlantic Coast. Mid-level flow will strengthen in the wake of these waves, coincident with another shortwave trough dropping from the northern Plains into the Mid MS Valley. The western CONUS ridging will continue gradually shifting eastward, ahead of a progressive shortwave trough forecast to move into the Pacific Northwest. By early Saturday, the upper ridging is expected to extend across the entire High Plains and into Alberta and Saskatchewan, with the shortwave trough extending from northwest WA/southwest British Columbia through the western Great Basin. At the surface, a cold and dry airmass is expected to remain in place east of the Rockies, with associated high pressure contributing to mostly offshore low-level flow. The only exception is across the TX Coast, where some more easterly flow may exist along the northern periphery of a low over the western Gulf. Some lower 60s dewpoints may advect into south TX, but warm mid-level temperatures should still preclude deep convection and any lightning. ..Mosier.. 01/01/2025 Read more

CORRECTED FOR TYPO IN DISCUSSION ...SUMMARY... Thunderstorms are not expected Thursday. ...Synopsis and Discussion... A shortwave trough is forecast to rotate through the central/eastern CONUS upper troughing on Thursday, progressing cyclonically from the central Plains through the Mid MS Valley into the Southeast States and southern Appalachians. Another shortwave trough is expected to drop southeastward through the Upper Midwest early Friday morning. Progression of these waves will help maintain upper troughing east of the Rockies through Friday morning. Farther west, expansive upper ridging will gradually shift eastward throughout the day, ending the period extended from northern Mexico into western British Columbia. A strong shortwave trough will approach the Pacific Northwest coast, but is expected to remain offshore throughout the period. The surface pattern is expected to feature ridging centered over the TN Valley, resulting in offshore flow across the majority of the CONUS. Another surge of cold air is anticipated across the Plains, helping to reinforce the cold and dry conditions already in place. Easterly/northeasterly surface winds are forecast across the Gulf of Mexico, but the development of a weak surface low just off the south TX coast should preclude any low-level moisture from advecting inland. Consequently, any thunderstorms activity should stay over the western Gulf. Dry and stable conditions will prevent thunderstorm development elsewhere. ..Mosier.. 01/01/2025 Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0344 PM CST Tue Dec 31 2024 Valid 021200Z - 081200Z ...Synopsis... An amplifying upper-level ridge will traverse the western CONUS Day 3/Thursday, and then move over the Rockies Day 4/Friday, while troughing persists over the eastern half of CONUS. A Pacific trough will likely move onshore by early Day 5/Saturday, and then into the Southern Plains late this weekend. ...Day 3/Thursday Southern CA... One more night of localized Santa Ana winds will remain possible across the Transverse Ranges. The most likely areas to experience a few hours of near critical RH/wind combinations will be on the seaward facing slopes and valleys. For now, confidence remains too low to justify an increase to 70% probabilities since only very localized critical relative humidity is anticipated. This will be monitored closely in subsequent forecasts. ...Day 5-6 Saturday-Sunday High Plains of NM/Southern Plains... Increasing mid level flow associated with a shortwave trough moving into the Southern Plains this weekend, along with accompanying pressure falls in the lee of the Rockies, will aid in breezy conditions developing from NM eastward into the Southern Plains. Dry southerly flow could develop across the TX Panhandle Day 5 Saturday before low level moisture begins to increase from southern TX northward to near OK Day 6 Sunday. Further west, downslope westerly flow should persist from NM into west TX. If confidence in the timing and location of the shortwave trough were slightly better, low critical probabilities would have been introduced for at least west TX Day 6 Sunday. ..Barnes.. 12/31/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

Damaging gusts, isolated hail, and a brief tornado remain possible this afternoon from the central Appalachians into parts of the Mid-Atlantic. ...20z Update... The previous forecast remains valid with minimal changes. The western edge of the Marginal Risk area has been removed from portions of eastern KY and western WV, as the aforementioned upper trough has moved eastward. Weak buoyancy (200-400 J/kg MUCAPE) is present across parts of WV and VA where clear skies have allowed surface temperatures to warm to near 60 F beneath the mid-level cold core. Despite very minimal surface moisture (dewpoints in the 30 to 40s F) steep mid and low-level lapse rates (7-7.5 C/km) will continue to allow for 35-50 kt of 0-3 km flow to mix down to the surface. Several gusts of 45+ kt have been observed with low topped convective bands ahead of and along the cold front. As these storms move eastward, they will continue to pose a risk for damaging winds through the afternoon. Isolated small hail and perhaps a brief tornado also remain possible with any stronger rotating cells, given relatively strong low-level speed shear. See the prior discussion and MCD 2322 for more info. ..Lyons.. 12/31/2024 .PREV DISCUSSION... /ISSUED 1025 AM CST Tue Dec 31 2024/ ...KY to the Mid Atlantic Region... A potent, negatively-tilted shortwave trough will move from the upper OH Valley into NY/PA today, with an associated 80-100 knot mid-level speed max nosing across the Carolinas. Strong large-scale forcing and low-level warm advection is resulting in sufficient lift for the development of multiple lines/clusters of low-topped convection (some with lightning) across parts of OH/KY/TN/WV. This activity will move quickly eastward through the day across the central Appalachians and into the Mid Atlantic region this afternoon/evening. Forecast soundings show cold mid-level temperatures, resulting in steep lapse rates aloft. This will continue to support a threat of thunderstorms through tonight. Low-level moisture is quite limited, and forecast CAPE values are below 500 J/kg. Nevertheless, low and mid-level wind fields are very strong, which could easily mix down within any more-organized convection. Low-level shear is also strong enough to support updraft rotation (as already noted in a few cells this morning in KY) which could pose a risk of a brief tornado or occasional hail through the period.

DISCUSSION...Convectively enhanced surface gusts have increased a bit in number and strength along the western slopes of the Allegheny Mountains. This is where low-level lapse rates have become rather steep in response to continuing insolation and mid-level cooling. Across the higher terrain into the eastern slopes of the Allegheny mountains and Blue Ridge, the boundary-layer remains cooler and more stable to both updrafts and downward mixing of momentum. Although this could be modified somewhat by the mid-level cooling, convection and potential for strong surface gusts seem likely to diminish during the next hour or two as forcing for ascent spreads eastward. ..Kerr/Hart.. 12/31/2024 ...Please see www.spc.noaa.gov for graphic product...

Thunderstorms are not expected Thursday. ...Synopsis... A stable pattern will persist through Thursday, with an upper ridge along the West Coast and a broad region of cyclonic flow aloft to the east. That ridge will push eastward across the Great Basin through Friday morning, as a shortwave trough approaches the coastal Pacific Northwest. Meanwhile, an embedded wave is forecast to amplify toward the lower MS Valley/Southeast, with developing precipitation from LA into southern MS and AL. At the surface, high pressure will be in place over the Southeast, with east to northeast winds across the Gulf of Mexico. A secondary surge of polar air will spread south across the MO/MS Valleys late, pushing the moist air mass just off the TX Coast even farther south.
