Potential for severe weather appears low on Sunday. ...Synopsis... On Sunday, an upper-level trough will move through the Lower Great Lakes and Northeast. Surface high pressure will build most areas east of the Divide. A surface cold front will likely remain in parts of the eastern Carolinas and the Southeast. Within the southern/central High Plains, low-level moisture return will begin on the western flank of the surface high. ...Eastern Carolinas... Mid-level winds will be moderately strong within the southern Mid-Atlantic region. These winds will weaken quickly with southern extent across the Carolinas into the Southeast. Ample cloud cover will stunt surface heating. Even so, widely scattered to scattered convection appears possible along the front in the coastal plains region. Where locally greater heating can occur, a stronger storm or two could develop and produce localized gusty winds. ...Central/Southern High Plains... A narrow zone of modest MLCAPE (around 1000 J/kg, generally) will develop as moisture returns northward. Storms are more likely to develop within the higher terrain with more uncertainty along the lee trough. Forcing for ascent will be nebulous and at least weak inhibition may lead to limited coverage and duration of any activity. Models do depict a subtle perturbation approaching the central High Plains towards late afternoon. Later developing convection would likely be elevated, sustained by the low-level jet. With modest shear and buoyancy, the stronger storms could produce small/low-end hail, but overall severe risk continues to appear low. ..Wendt.. 09/06/2025 Read more

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 PM PDT Fri Sep 5 2025

For the eastern and central North Pacific east of 180 longitude:

Active Systems:
The National Hurricane Center is issuing advisories on Hurricane
Kiko, located in the eastern Pacific basin well east-southeast of
Hilo, Hawaii. Kiko is expected to cross into the central Pacific
basin late tonight.

Central East Pacific:
An area of low pressure could develop in the central portion of the
eastern Pacific, well south of the Baja California peninsula, during
the early part of next week. Some slow development of this system is
possible thereafter as it moves generally westward around 10 to 15
mph over the open waters of the eastern Pacific.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.

DISCUSSION...An MCS continues to propagate eastward along the TX/OK border, and will soon enter AR. This MCS has an earlier history of producing severe gusts, though none have been reported over the last couple of hours. However, recently intensified convection north of the Metroplex has produced measured severe gusts. These storms are tracking into an environment characterized by up to 3000 J/kg MLCAPE and 30+ kts of effective bulk shear, whose vectors are oriented roughly normal to the ongoing linear convection. The expectation is for organized storms, including bowing segments, to continue propagating to the east amid this CAPE/shear parameter space. However, nocturnal cooling, and the impacts of overturning convection, are contributing to low-level stability, so the persistence of effective downward momentum transport for damaging or severe gusts is in question. Nonetheless, at least a few more strong to possibly severe gusts are plausible over the next few hours. ..Squitieri/Mosier.. 09/06/2025 ...Please see www.spc.noaa.gov for graphic product...

Scattered damaging wind gusts to 70 mph likely Scattered large hail events to 1.5 inches in diameter possible SUMMARY...Thunderstorm coverage is expected to increase along and ahead of a cold front progressing slowly southeastward through the region. Environmental conditions will support a few supercells capable of large hail and damaging gusts. Some clustering is possible over time, with damaging gusts possible within these storm clusters as well. The severe thunderstorm watch area is approximately along and 60 statute miles north and south of a line from 55 miles northwest of Muscle Shoals AL to 25 miles east southeast of Jackson KY. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU6). PRECAUTIONARY/PREPAREDNESS ACTIONS... REMEMBER...A Severe Thunderstorm Watch means conditions are favorable for 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. Severe thunderstorms can and occasionally do produce tornadoes. && AVIATION...A few severe thunderstorms with hail surface and aloft to 1.5 inches.

Hurricane Kiko Forecast Discussion Number 24

3 weeks 1 day ago
Issued at 500 PM HST Fri Sep 05 2025 906 WTPZ41 KNHC 060237 TCDEP1 Hurricane Kiko Discussion Number 24 NWS National Hurricane Center Miami FL EP112025 500 PM HST Fri Sep 05 2025 Kiko has continued to intensify this afternoon and remains a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. The eye is now surrounded by a large ring of very cold cloud tops, and the cyclone has taken on a structure more typical of annular hurricanes. A GMI microwave pass from 2224 UTC confirmed a symmetric inner-core with a complete ring of deep convection around the eye. The latest objective estimates from UW-CIMSS are as high as 122 kt. Subjective Dvorak classifications from SAB and TAFB are both T6.0/115 kt. Blending the higher objective estimates with the slightly lower subjective classifications yields an initial intensity of 120 kt. Kiko is moving west-northwestward, or 290 degrees at 10 kt. The cyclone remains steered along the southwestern flank of a subtropical ridge, while an upper-level low north of Hawaii is helping to erode the western periphery of the ridge. This general motion with some increase in forward speed should persist through the weekend, with Kiko expected to cross into the central Pacific basin late tonight or early Saturday. The official forecast track is near the HCCA consensus and essentially unchanged from the previous advisory. However, a track slightly to the left of the official forecast would bring Kiko closer to the Big Island. Historically, cyclones approaching the Big Island from the east can slow and deflect northward as the island terrain disrupts the low-level flow and alters the steering currents. Kiko should remain a powerful hurricane for the next 12–24 hours while traversing 26–27 C waters with light north-northeasterly shear. Its annular structure may allow it to resist weakening longer than typical guidance, despite the surrounding dry environment in the mid- to upper levels. Beyond 48 hours, a combination of cooler waters, dry mid-level air, and strengthening west-southwesterly shear exceeding 30 kt will likely induce rapid weakening. The official intensity forecast holds Kiko above most of the available guidance into the weekend, then trends more toward the consensus aids later in the weekend and early next week. Key Messages: 1. Kiko is forecast to approach the Hawaiian Islands during the early to the middle portion of next week. Impacts from rain and wind remain a possibility, but it is too soon to determine the exact location or magnitude of these impacts, and interests there should continue to monitor the progress of this storm. 2. Swells generated by Kiko are expected to begin reaching the Big Island and Maui by Sunday. These swells will gradually build and are forecast to peak along east facing exposures of the Hawaiian Islands late Monday through midweek, potentially producing life-threatening surf and rip currents. Listen for later advisories and possible warnings from the National Weather Service.
