After Dumping Snow in the West, The Next Eastern Storm Will Likely Be More Wet Than Wintry

A new storm system now sweeping into the Pacific Northwest will emerge over the central and eastern United States, where it will likely produce more rain than snow or ice late this week into the weekend.

Rain and mountain snow, heavy at times, are expected in the Northwest Tuesday, with snow then spreading into the Rockies by Wednesday. Several feet of snow are expected in the Washington Cascades, and over a foot of snow may blanket parts of the northern Rockies.

The system will emerge over the Plains and Midwest Thursday before slowly moving toward the East Coast Friday into the weekend.

With limited cold air east of the Rockies the next several days, any snow or ice from this next storm should be very limited and confined to the nation's northern tier, unlike Winter Storm Diego, which produced heavy snow and ice in the South.

Dense fog affects morning commute

A dense fog is expected to limit visibility through the morning to less than one-quarter mile at times throughout the Bay Area, according to the National Weather Service.

As of 4 a.m., visibility was a quarter mile or less in Concord, Livermore, Napa, Novato, Oakland and San Carlos, resulting in the weather service issuing a dense fog advisory until 10 a.m.

While there is a slight chance of rain in northern Sonoma County on Tuesday night, most of the Bay Area is expected to be dry and seasonably cool through Thursday.

Another system will bring a chance of rain to the region Friday, especially for areas north of the Golden Gate, according to the weather service. A potentially wetter system is expected to deliver widespread rain to the region Sunday.

Climate change was behind 15 weather disasters in 2017

A drought scorched the Great Plains, causing wildfires and $2.5 billion in agriculture losses. Catastrophic floods submerged more than a third of Bangladesh. Record-shattering heat waves killed scores of people in Europe and China.

These were among 15 extreme weather events in 2017 that were made more likely by human-caused climate change, according to in-depth studies published this week in the Bulletin of the American Meteorological Society. At least one episode — a devastating marine heat wave off the coast of Australia that cooked ecosystems and damaged fisheries — would have been “virtually impossible” without human influence, scientists said.

The findings, presented Monday at a meeting of the American Geophysical Union, underscore the degree to which climate change is already harming human society, researchers said.

Blustery weather continues, more surf on the way

A series of high pressure systems passing north of the islands will maintain breezy, and strong trade winds through most of the week. The high will begin weakening on Friday and into the weekend, leading to calmer trades. A band of clouds and showers is expected to fall apart in the next couple of days with less trade wind showers on tap for most of the second half of the week. A change in the weather is expected early next week as a front approaches the islands from the northwest.

The first forerunners of a new long-period northwest swell are expected to begin arriving late tonight or early Tuesday, with this swell slowly building through the remainder of the day and Tuesday night, before peaking on Wednesday. Surf is expected to near High Surf Advisory (HSA) levels on Wednesday along exposed north and west facing shores. A smaller northwest swell is then expected on Friday, followed by a new and larger northwest swell late in the weekend into early next week

The Weirdest Weather Events of 2018 So Far

Freezing Rain in Florida

Just after New Year's Day, Winter Storm Grayson blanketed Tallahassee, Florida, with its first measurable snow since 1989, and the first January such occurrence, there, in records dating to 1885. That's eye-catching enough.  What was even more bizarre was seeing an ice accumulation map involving the Sunshine State. Up to a quarter inch of ice accumulation was measured in Lake City, and light icing on elevated surfaces was reported as far south as Levy County. 

February 80s in New England

The heat in New England Feb. 20-21 was the "most extraordinary heat event to ever affect the Northeastern quadrant of the U.S. during the month of February, since official records began in the late 1800s," according to Weather Underground weather historian Christopher Burt. All-time state February heat records were tied or broken in eight states, including 77 degrees at Wells, Maine, 80 degrees at Fitchburg, Massachusetts, 83 degrees at Harrisburg, Pennsylvania, and 80 degrees at Cincinnati's Lunken Airport. 

 

The Four-easters

Perhaps as payback for the summerlike February heat wave, four nor'easters – Winter Storms Riley, Quinn, Skylar and Toby – in three weeks brought misery to millions along the Eastern Seaboard in March 2018. Incredibly, a fifth low-pressure center was a bit too far offshore near the end of March to join the fearsome foursome from earlier in the month.

Warmer weather will usher in storms

High pressure moves across the deep south today, bringing dry and milder conditions to Region 8.

It won’t feel quite as cold this afternoon as highs reach 47 under mostly sunny skies.

Winds stay up tonight as cloud cover rolls into Region 8.

This should hold overnight lows in the 40s.

We’ll enjoy a warming trend into the mid 50s through the rest of the week.

Rain chances come with our milder weather.

Winter weather alerts cancelled, re-freeze likely at night

As of 1 p.m. Wednesday, 1.5 inches of snow has fallen at our headquarters in Pleasantville; 2 inches of snow has fallen in Mays Landing. The combination of the previous snow, in addition to future forecasts has put Atlantic County into a Winter Storm Warning through 6 p.m.

The Winter Weather Advisory was also expanded into Cape May and Cumberland Counties, which will be in effect until 6 p.m. Ocean County remains in a Winter Weather Advisory.

The snow, which was light for much of the morning, has become heavier as the afternoon occurred. Moderate snow, with a visibility between a quarter and three-quarters of a mile, have become common in parts of Atlantic and Cumberland Counties.

The story for this starts a few thousand feet about our heads. At the 850 millibar level, about 5,000 feet high, South Jersey is in a region of frontogenesis, or an area where a localized front forms. In this case, the inverted trough that we've talked about for a few days is helping with this.

Black ice the next threat for the Raleigh-Durham region

With the winter storm wrapping up and exiting the region Monday night, a quieter weather pattern will emerge for much of the rest of the week.

After the wintery precipitation from earlier today, drier weather will filter into most of the viewing area -- but some places, like Goldsboro or Kenly, got an evening dusting of snow.

Overnight, black ice is the main concern as wet or slushy areas will freeze.

Since the start of the storm, troopers with the NC State Highway Patrol have responded to 672 collisions and 1,571 calls for service. Crews with NCDOT have used 3,500 tons of salt on roadways across the state.

Most counties are under a Winter Weather Advisory until 9 a.m. Tuesday.

The storm that blew through North Carolina on Sunday dropped 14 inches of snowin parts of the Triangle.
