Western Winter Storm and Florida Cold

A large winter storm has most of the western US under winter storm (pink) and blizzard warnings (red).Southeast Arizona including the Tucson area is under hard freeze (dark blue) and winter storm warnings. Higher elevations - even right down to the Mexican border - are under blizzard warnings incuding Bisbee. A gale warning is active for the entire West Coast.

Low temperatures on the morning of December 28th in Florida included 24 at Daytona Beach, 27 at Sarasota, 32 at Tampa, 34 at West Palm Beach, 39 at Miami, 44 at Marathon, and 49 at Key West.

Winter Weather for East Coast/Europe/Australia

A monster 961 mb blizzard hit the East Coast today and yesterday.
Yesterday afternoon, blizzard warnings (red) were in effect along the coast from Maine to New Jersey, with winter storm (pink) and storm warnings (purple) going down to South Carolina.
Up to 32" of snow fell in New Jersey (Rahway) and winds gusted to 80 mph on Cape Cod (Wellfleet). As much as 29" fell on Staten Island (Great Kills), and 24.5" on Long Island (Marine Park) with JFK Airport receiving 15.5", Upton 18.8", and Central Park 20".

The heavy snow and high winds crippled travel and knocked out power across the northeast. In New York City, buses were stranded, and a subway train and its passengers were stuck in the snow for hours.

Marine life is being threatened by the low temperatures even down to South Carolina.

Columbia, SC had the first significant Christmas snow since records began in 1887, and the Atlanta area had the first measurable snow on Christmas since 1881.

This storm has pushed arctic air into southern Florida.
850 mb temps from this morning's soundings were -3C at Cape Canaveral, -4C at Tampa, 0C at Miami, and 2C at Key West. Hard freeze warnings (dark blue) have again been issued for southern Florida:On December 21st, this huge storm (964 mb on December 23 0Z) missed most of the East Coast:The Gulf Stream, which normally allows storms to form closer to the coast, has been flowing farther east than normal:
At buoy 41025 near Cape Hatteras, the water temperature was only 47F during this storm. What is interesting about today's East Coast blizzard is that it happened despite a water temperature at the same buoy currently at only 43F.

The harsh winter continues to affect Europe, from Germany to Britain and France. In Britain, where December is expected to be the coldest in 100 years, flights and trains were canceled because of more heavy snow. In Paris, flights were canceled at Charles De Gaulle Airport because of a shortage of antifreeze, and part of the airport was evacuated because fears of a roof collapse under the weight of a foot of snow. Even Australia had 30 cm of snow in New South Wales during their summer. The storm can be seen on these charts from December 19th:
Some are even saying that the cold and snow is because of global warming.

Greenland High at 1078 mb

On yesterday's (December 15th) 18Z (12:00PM CST) surface analysis chart from the Ocean Prediction Center, the Greenland high was at an incredible 1078 mb:
A GFS analysis chart from the same time shows the enormous upper ridge over the northwest Atlantic and the strong convergent flow across central Greenland:

Second Round of Record Cold in Florida

An arctic outbreak put the 540 line near Tampa, FL on the morning of December 13th:
At 850 mb, temperatures as cold as -8C were pushing into northern Florida as the freezeing line hovered near Lake Okeechobee.
Hard freeze warnings (dark blue) went down to southern Florida on Tuesday night (14th).

Major Midwest Blizzard Underway

A large winter storm has hit the Midwest with 26" of snow (Winona, MN) and wind gusts up to 62 mph (Grand Island, NE). At Rochester, MN, 15" of snow broke the record of 5.5" set in 1893 for December 11th, and the record for daily snowfall for December. The old record was 10.3" on December 25th, 1955. The snow even collapsed the Minneapolis Metrodome. The storm total reported at Minneapolis/St Paul international Airport was 17.1".

Last night, blizzard warnings (red) went from Nebraska and South Dakota to Michigan:
Winter storm warnings are in pink, winter weather advisories in purple, and wind chill advisories in light blue. Because of arctic air surging southward behind this storm, the current map again has hard freeze warnings (dark blue) along the Gulf Coast, freeze warnings (light blue) for southern Texas and New Orleans, wind chill advisories for central Florida, and wind chill watches for southern Florida.
In Florida, 6Z GFS MOS has low temperatures for Tuesday morning at 18 for Gainesville, 24 for Daytona Beach, 37 for Miami, and 53 for Key West.

The low temperature of 50F at Cancun yesterday morning (December 8th) was the coldest ever for the entire month of December.

In Britain, the Army was called in to help clear away snow as temperatures dropped to -15C (5F). Additionally, it was found that at the station with the longest temperature record in the world (since 1659, although daily records began in 1772) in central England, the last week in November and first week in December were the coldest ever. The Eiffel Tower was closed after Paris was hit with the heaviest one-day snow (11 cm) since 1987.

In Florida, Tallahassee, Jacksonville, and Gainesville are all under freeze warnings.
The current dewpoint in Miami is 34.

Tropical Storm Shary and Midwest Storm

On October 28th, at 9PM, (3Z, 29th) this area of convection just south of Bermuda was named Tropical Storm Shary.
It was in a strongly sheared environment on the northeast edge of a large closed upper low. Upper level winds were strong enough to push clouds to the Bahamas:
The large tropical wave which later became Tomas can be seen east of the Lesser Antilles and Venezuela. GFS analysis shows that the area in which Shary is located had 250 mb wind speeds in the 30-40 knot range:
The surface low is well southeast of the convection, and the strongest winds are due to a tight pressure gradient with the subtropical ridge to the north:
The 955.2 mb Midwest storm from October 26th was not the record for the lowest pressure in a non-tropical storm in the Continental U.S. A reading of 955.0 was confirmed at Block Island, RI on March 7th, 1932 and at Canton, NY on January 3rd, 1913. The October 26th storm is still the record for any Midwest storm.

A storm near the Aleutians bottomed out at 939 mb last night:
Buoy 46205 west of British Columbia just (as of 0Z) reported 48.6 knot winds with gusts to 64.1, and 34.1 foot waves.

Midwest Storm Drops to 955 mb

At 5:13 PM on October 26th the pressure reported from Bigfork, MN was 955.2 mb (28.21 inches). This set a new record for the lowest pressure in a non-tropical storm in the Continental U.S. New low pressure records were also set at Duluth, International Falls, the state of Wisconsin, and La Crosse. More here.

This storm dumped 8.5" of snow in North Dakota, and 8" in northeast Minnesota, including a record 7.7" at Duluth. Winds gusted to 70 mph or greater in North Dakota (70),South Dakota (75), Wisconsin (76), Illinois (70), Michigan (78 on Mackinac Bridge), and Indiana (77). Water vapor imagery reveals the scale of this storm.Lubbock, TX is now under frost advisory, and Roswell, NM a hard freeze warning.
