The Dogs of Winter May Start Howling Again Soon.

There are growing signs that Arctic air may return to the U.S. by late next week as the mild weather pattern of the last ten days begins to fall apart. There is still a lot of uncertainty about whether or not this pattern will lock in or if this will be just a temporary blast of cold before milder Pacific air takes back over. The big clue to these changes is …

“Blue Norther” Cold Front Charges Through The Plains

Snow, with winds gusting nearly 40 mph was Mother Nature’s way of welcoming folks in Western Kansas to November today. The folks in the Plains call this type of front a “blue norther” and they move fast bringing rapid temperature drops along with strong winds. This system will move into the Eastern USA tomorrow and bring blustery rains and a chill to much of the nation east of the Mississippi. …

True Color View of The Rare October Snowstorm From Space

    Danbury, Ct received 17 inches of snow from this rare October event, and the fact that leaves were still on many trees caused massive power outages. On a side note, Central Park has now reached its 3rd wettest year on record. See more snowfall totals from the NWS in New York, NY  below:

The Kentucky Smudge Explained

While working on the forecast today, I called up this 1km resolution visible image from the GOES East (From NASA MSFC) and immediately spotted this weird-looking smudge. I knew pretty quickly what it was and how it happened, but the exact details took a little work and involve some very basic thermodynamics. My fellow meteorologist Brandon Chambers took a hard look at it while I worked on the forecast for …

Warmest October Day Ever in the UK Saturday

My Closet friend was at Salisbury Cathedral Saturday after a drive down from his home in Wales. His car thermometer registered 29° C. That’s 84 degrees Fahrenheit and by UK standards in October, that isn’t just unusual it’s nearly unbelievable! Just some high clouds covered Southern England on Saturday, while an approaching cool front from the Atlantic kept Scotland and North Wales a bit cooler. The 500 millibar chart (surface pressures …

First Widespread Autumn Chill Headed For the Eastern U.S.

  Get ready for a cool down if you live in the East! For many folks from the Plains to the Deep South, this weekend will be the first time they have to turn on the heat and it will be a stark reminder that the hot summer of 2011 is in the history books. The NWP models are in close agreement that as the cold core low over the …

An Atmospheric Train Wreck

The folks at the NOAA Environmental Visualization Lab have a nice long loop from the GOES water vapor channel out today. It shows the huge cutoff low that has been stuck over the Midwest for several days. I’ve been dealing with this in my day-to-day forecasting as well, and these things can be very tricky to forecast. These are what meteorologists call a cold core low and they are more …

Irene’s Core Heads for The Big Apple; Hurricane Warning for New York

  Irene is now a cat two storm and the wind shear has weakened it just a bit today. The wind field is very large though and flood models are indicating that it will produce significant flooding, perhaps as high as a category two storm in some places. Winds may gust to hurricane force in NYC, but sustained winds will likely be at tropical storm strength as it passes, and …

Is This Tropical Storm Jose??

  The tropical wave off Africa has intensified and is looking very healthy this evening. It even looks like an anticyclone has developed aloft over the wave, and we may have tropical storm Jose soon (if not already). Water vapor imagery from the European weather satellite also shows little dry air in the region, although there is some dry air to the north of the system (not enough to seriously …
