Northeast: the coastal storm is winding down. The Weather Prediction Center (WPC, 2:23 AM EST Fri Nov 13) says wrap-around showers linger over New England, with rain changing to snow on higher ground, scattered showers in the Northeast, Ohio Valley and Mid-Atlantic, and a chance of snow at high elevations in the Appalachians; lake-effect rain and snow continues over the Great Lakes through Saturday. The NWS in Binghamton says 6 to 12 inches of heavy, wet snow has fallen above 1,500 feet in Otsego County, N.Y., sticking to trees and causing power outages, with up to 2 more inches before its Winter Storm Warning ends at 1 PM today. The NWS in Mount Holly has a Coastal Flood Warning for Ocean County, N.J., from 9 AM to 3 PM today, with 1 to 2 feet of water possible in low-lying areas near shorelines and tidal waterways and many roads possibly impassable. NBC Boston called the storm low-impact for most of New England, with a risk of minor coastal flooding around Nantucket Harbor at this afternoon's high tide. West: WPC says a deep Pacific trough brings widespread rain and wind to the West Coast today, moderate to heavy rain in Washington, Oregon and northern California, and moderate to heavy snow in the Sierra through Saturday, with another surge of moisture Saturday that may cause localized flooding on the Northwest Washington coast (WPC's wording today is moderate to heavy snow; yesterday it said blizzard conditions were likely in the higher Sierra Friday night). NWS Winter Storm Warnings for the Sierra run from 10 AM or 1 PM today: Greater Lake Tahoe (to 10 AM Saturday; about 12 inches above 7,000 feet and up to 20 inches on the crest west of the lake, ridge gusts of 70 to 90 mph and 45 to 55 mph in Truckee and lakeside towns); the northern Sierra above 6,000 feet including I-80, Highway 50 and Lassen (6 to 12 inches, up to 18 on the highest peaks); Mono County (1 to 2 feet above 7,000 feet, ridge gusts of 60 to 80 mph); eastern Inyo County slopes (5 to 10 inches, to 4 PM Saturday); and Yosemite, Kings Canyon and Sequoia above 6,000 feet (up to 18 inches, to 4 AM Tuesday). All say travel could be very difficult to impossible and the Friday evening commute will be affected. High Wind Warnings this morning for the Del Norte coast, Calif. (gusts to 60 mph), the Curry County and south-central Oregon coast (to 65 mph) and central Siskiyou County, with the NWS expecting widespread power outages on the coasts; a Coastal Flood Warning for San Juan County, Wash., this morning (2.5 to 3 feet of inundation possible); and high surf of 18 to 25 feet and a Coastal Flood Warning for San Luis Obispo and Santa Barbara County beaches Saturday. South: the hard freeze is arriving. NWS Freeze Warnings cover all of central Alabama and much of north Alabama (lows as low as 26 to 32), central and northern Mississippi (as low as 28), north and west-central Georgia (as low as 29) for Saturday morning, and again Sunday morning in Alabama and Mississippi; also central North Carolina and southeast Virginia (as low as 29 to 30) Saturday morning, and northeast Oklahoma and northern Arkansas this morning (28 to 29). Freeze Watches extend Sunday morning across the Atlanta area, much of South Carolina and eastern North Carolina, and Saturday morning to southwest Alabama (NWS Mobile). The NWS says the cold could kill crops and sensitive plants and damage unprotected outdoor plumbing. Storm Prediction Center (Day 1, 11:10 PM CST Nov 12): no severe storms forecast in the US today; scattered storms with gusty winds and small hail possible in southern Arizona, New Mexico and far west Texas. NWS alerts feed: no Tornado Warnings; Flood Warnings continue in central Florida (Lake, Volusia, Seminole, Brevard, DeSoto), McMullen County, Texas, and Maricopa and Yuma counties, Ariz. (to Nov 17); Alaska blizzard and freezing-spray warnings on the Arctic coast. Tropics (National Hurricane Center, 1 AM EST Nov 13): no Atlantic formation expected in 7 days; Tropical Storm Pena has weakened to a remnant low well west-southwest of Hawaii with a 10% chance of redeveloping before it crosses the Date Line today. Space weather (NOAA Space Weather Prediction Center, 08:46 UTC Nov 13): SWPC rates three things on 1-to-5 scales: G for geomagnetic storms (which can stress power grids), R for radio blackouts from solar flares (which disrupt high-frequency radio), and S for solar radiation storms (mainly a concern for satellites and polar flights). All three are at 0 now, and no radio blackouts were observed in the past 24 hours. G is forecast to stay at 0 through Nov 15 (highest expected Kp 1.67; no storms expected). Chance of R1-R2 blackouts is 35% and R3 or greater 5% per day through Nov 15 (down from 45% yesterday) as sunspot Region 4566 rotates off the Sun's western edge; S1 chance 5%. SWPC's high-energy electron flux alert continues (a satellite-charging concern, not a grid concern; yesterday's peak 3,235 pfu, down from 7,897). No G3 or higher and no SWPC grid warning.
