Snowstorm Hammering the Northeast U.S. to Start December

Written by Team Morecast

 

A large, powerful winter storm has traversed the U.S. since the middle of last week. Major snow accumulations were tallied from the western mountain ranges into  Northern Plains through the late week. Heavy snows have been falling over the interior Northeast since Sunday. Thus far the major coastal cities have been mostly spared, however that could change as colder air filters in on the back side of the storm on Monday night.

 

 

 

The storm initially plowed into the west coast on Tuesday and Wednesday of last week. The western ranges were buried by snows up to 3-4 feet (90-120 cm) in some locations! The heavy snows spread into the Northern Plains and Upper Midwest by the late week, accompanied by high winds, leading to dangerous blizzard conditions. High winds were an issue even on the warm side of the system to the south. Gusts exceeding 60 mph (100 kph) were common across the West, the southern Rockies, and the Plains. Some isolated wind-prone areas reported gusts of 80-100 mph (130-160 kph).

 

 

Now the system is pounding the Northeast with snowfall rates reportedly 1-2 inches (2-5 cm) per hour. After an initial mix of sleet and freezing rain, the major coastal cities like New York City and Boston have changed to rain. However, as the system starts to pull off the coast on Monday, cold air will be dragged south. Rain will mix with and change to snow and several inches could accumulate. At this time, it appears Boston could see storm totals of 3-6 inches (7-15 cm), higher on the inland side of the metro area. NYC stands to see more like 2-3 inches (4-7 cm), but even that would be enough to disrupt the morning commute on Tuesday. Much higher totals of 1-2 feet (30-60 cm) are likely for interior New England.

Big Winter Storm May Leave Midwesterners Less Than Thankful on Thanksgiving

Written by Team Morecast

 

The strongest winter storm of the early season has spun up over the central states. Heavy snows of one to two feet (25-50 cm) have already crippled the Denver, Colorado region. Boulder experienced their third-snowiest day ever with 22.3″ (56.6 cm) of snow. Now the storm is rolling into the Plains with a wide variety of weather hazards expected, from tornadoes to a blinding blizzard! Travelers looking to hit the road on the day before Thanksgiving could face major delays.

 

 

The heaviest snow tonight is falling over the Upper Midwest, including the Minneapolis-St. Paul metro area. Interstate 80 through central Nebraska has been forced to close due to the dangerous conditions. Accumulation rates up to two inches per hour (5 cm/hr) are reported within these bands. Residents of these areas may even experience some rare thundersnow!  Gusty north winds will blow and drift the snow, leading to dangerous blizzard conditions with very limited visibilities. Many areas will see 6 to 12 inches (15-30 cm) of total accumulation, and a few spots will see more, especially in the western Great Lakes.

 

 

Areas to the south will see warm-weather hazards including damaging winds and even a few isolated tornadoes. Gusts up to 60 mph (100 kph) will be common from the Midwest to the southern Great Lakes, including the Chicago metro area. Scattered storms will also race through the region with dangerous winds. An isolated tornado or two can’t be ruled out of the question! These winds will knock down large branches and powerlines, leading to some power outages. Lead photo courtesy MTA Bridges and Tunnels.

 

Eastern Australia Fearing a Historic Wildfire Season

Written by Team Morecast

 

Dozens of wildfires raging across mainly the highlands of eastern New South Wales and southeast Queensland have claimed at least three lives. Several others are missing and feared lost. Hundreds of homes have been destroyed and thousands of residents have been evacuated. Officials are worried that this is only the beginning of a record-breaking wildfire season as summer heat is just beginning to build.

 

 

The satellite imagery above shows massive smoke plumes billowing from the fires down over the populated coastal plain. More than 1,500 firefighters have been engaged to contain the wildfires, straining resources across the entire region. The widespread wildfires are due in large part to severe drought conditions that have been plaguing much of NSW and southern QLD for the better part of two years. The soil moisture map below shows the dangerously dry conditions, in some places at record low levels. Significant improvement is not expected in the near future as late spring turns to summer. Dry, periodically windy conditions are likely to continue to fan the flames. Lead photo courtesy of Wikipedia contributor Scott L.

 

California Wildfire Update: Danger Shifting South to the L.A. Basin!

Written by Team Morecast

 

The massive Kincade fire continues to burn tens of thousands of acres in the Sonoma wine country just north of San Francisco, California. Thousands of residents have been evacuated, while hundreds of thousands of others face days-long power outages. Now high winds and dry heat are expected to make for extremely hazardous fire conditions further south, in the Los Angeles basin, for Wednesday.

 

 

The Kincade fire has consumed more than 75,000 acres (300 square km) in Sonoma County since it ignited late last week, so large that it can be seen easily from space (see image at top). Periodic high winds have prevented a firefighting force of thousands from gaining the upper hand. As of Tuesday, only 15% of the fire has been controlled. In an effort to prevent additional fires from igniting, regional supplier PG&E has cut power to nearly 1,000,000 customers in central California. These controlled blackouts help reduce the threat of live wires downed by the high winds sparking new flames. But the blackouts have added to criticism of the company already forced into bankruptcy due to deadly wildfires for which they were found responsible in 2017-18. Fortunately for central California, winds have begun to diminish and temperatures are falling towards winter-like values.

 

 

Unfortunately, the same cannot be said further south towards the L.A. Basin. Months with no measurable rainfall have left plenty of dry scrub brush, ideal fuel for potential wildfires. The notorious Santa Ana winds are expected to blow on Wednesday with gusts approaching 60-80 mph (100-130 kph) in some spots (see animation above). Any stray fire will rapidly spread out of control in these conditions, straining already over-stretched firefighting resources. Already this week a relatively small wildfire threatened the Getty Art Museum and forced the evacuation of thousands, including basketball star LeBron James and actor Arnold Schwarzenegger. Lead photo courtesy Sentinel satellite data, processed by Pierre Markuse.
