South: Strong-to-severe storms rumble on along the Gulf Coast last night into today. An advancing frontal system will continue to move through the Deep South, dragging along with it rain showers and the threat for thunderstorms. Through this morning, that threat extends from the ArkLaTex to Mississippi, with the severity of the storms increasing as you move southward towards the coast. This system traverses the South with heavy rain and thunderstorms for southern portions of Mississippi, Alabama, and Georgia as well as the panhandle of Florida throughout the day. Gulf moisture moves beyond the Tennessee Valley and into the Ohio Valley where afternoon and evening showers are expected to fire.
West: Winter storm advisories are in effect for the Wasatch mountain range in Utah and north and central Colorado in anticipation of high accumulations of snow resulting from an advancing system across the Intermountain West. Snow levels in these regions will remain above 7,000 feet, and accumulation could exceed a foot with winds of 20 to 30 mph creating higher drifts. Behind the system, onshore flow will continue to drive Pacific moisture inland. Coastal showers and inland rain/snow showers will continue in earnest throughout the day. Additional snowfall accumulations for the Cascades and Sierra also could exceed a foot below pass level, making for dangerous driving conditions. Drier, warmer conditions will dominate the Southwest.
Midwest: Despite another round of snow showers from North Dakota to northern Wisconsin, the region as a whole remains relatively quiet. Tomorrow, the Northern Plains snow showers move over the Great Lakes, though any accumulations are expected to be light. There is a slight possibility for an isolated shower or thundershower for the fire-scorched areas around the Red River. Temperatures will be remain unseasonably warm today, with highs from the 50s and 60s surging as far as Nebraska and Iowa. 70s and 80s encompass most of Texas and Louisiana, with the possibility of even isolated reports of 90-degree highs in extreme south Texas.
Northeast: With the next storm not expected to arrive until tomorrow, the Northeast will enjoy a break that will be marked by dry conditions and mild temperatures. Ahead of the incoming system, winds will flow freely from the south and southwest, drawing warm, moist air to the region, though the threat of precipitation will hold off until the end of the week. Temperatures will be about 10 degrees warmer today than yesterday. As the pattern has been all winter, today's highs will be 5 to 15 degrees warmer than average. This all comes crashing down tomorrow as the approaching system will bring cooling showers, but more importantly will open the door for colder air to seep in from central Canada, a preview of the expected nationwide pattern change.

North Carolina: (Final) Explosion at Chemical Plant
Washington: Severe Weather and Flooding
Augustine Volcano continued to erupt Tuesday, with the volcano producing a continuous crescent-shaped plume of steam, and ash and gas speeding down the flanks of the island mount and into the sea.
The Alaska Volcano Observatory made hourly updates early Tuesday on its Web site with each one beginning the same way - "Eruption is in progress."
The volcano on an uninhabited island has been erupting since Saturday, with explosions thrusting particles almost five miles into the skies around south-central Alaska.
With winds shifting the ash away from major air routes, airlines cautiously resumed dozens of flights that had been canceled as a precaution. Ash particles can damage engines. Alaska Airlines on Tuesday resumed all flights to and from Kodiak Island and Anchorage, the state's largest air hub, said spokeswoman Amanda Tobin. The airline had canceled all of its 36 Anchorage flights Monday night as a precaution. Flights to and from Kodiak had been canceled Sunday and Monday. Era Aviation also was back to a normal schedule after canceling five flights to Kodiak Monday, according to President Paul Landis.
"This is a nonstory as long as public health is concerned, but it's a different thing for the aviation community," said Joel Curtis, lead forecaster at the National Weather Service. The volcano's constant release of gas, rock and ash - rather than a quiet buildup beneath the mountain - may be averting a more powerful eruption, said scientists at the Alaska Volcano Observatory. "This current material shows the vent is staying open and letting off pressure continuously," said Michelle Coombs, a geologist with the U.S. Geological Survey.
Wind currents were moving the ash in a northerly direction early Tuesday. A very light ash fall was expected over Kamishak Bay and northward to the western Cook Inlet. An ash fall advisory also was issued for the Alaska Range near the Big River Lakes area.
After a 10-day lull, Augustine resumed erupting Friday. The continuous ash plume began issuing from a newly cleared vent on Saturday afternoon, Coombs said. (Media Sources)
Current Level of Concern Color Code: ORANGE. Seismic data indicate that eruptive activity continues intermittently and has changed little in character or intensity over the past 24 hours. Ash clouds to altitudes greater than 15,000 ft. above sea level have not been observed on National Weather Service radar since 10:21 am EST on January 30 (15:21 UTC). Eruptive activity occurring now is characterized by low-level explosions, block-and-ash-flow style pyroclastic flows, and sustained production of ash. This type of activity is likely to continue for hours to days.
Further explosive activity producing ash clouds to altitudes over 25,000 feet may still occur with little or no warning. The Alaska Volcano Observatory (AVO) is monitoring the situation closely and the observatory is staffed 24/7. (NOAA/NWS, Alaska Volcano Observatory, Media Sources)
