Colorado Snow, Freeze Potential, Flooding Rains and a Severe Threat

Monday, September 17th, 2012

Thanks to the Breckenridge Ski Resort for this wintry picture… Some spots in the Colorado Rockies are recorded their first snowfall of the season today!

Arapahoe Basin

Here’s another shot from Arapahoe Basin just west of Denver, CO. I’m sure there are several folks that are ELATED to see this, while other aren’t quite ready for winter just yet.

Loveland Ski Area

Snow! Loveland Ski Area has been geting snow all morning. Check out the video footage of the moutnain covered in snow. Ski season is right around the corner.”

More Wintry Weather

The National Weather Service has issued a FREEZE WATCH for parts of northern MN and NW Wisconsin for tonight/AM Tuesday. Temps will bottom out in the mid 20s across a large chunk of the area, which will likely result in a killing freeze in these areas. COVER YOUR TOMATOES!

Forecast Lows Tonight

This is definitely SeptemBRRR like weather…

Frequent Fronts

This is about the time of year we start seeing outbreaks of cooler Canadian air dropping south of the international border and this week, there could be two outbreaks! The image below shows the temperatures a few thousand feet off the ground… note the cooler blue colors around the Great Lakes Region. This will result in temperatures nearly 10° to 15° cooler than average.

Forecast Highs Tuesday

This first big blob of cool weather will continue to sag south through Tuesday dropping temperatures throughout the eastern two-thirds of the nation.

Next Front

The GFS Model suggest another (more potent) cool front by late week/weekend across the eastern part of the country. This one looks to bring even chillier air with the potential of even more widespread frost/freeze.

Severe Threat Tuesday

This first front will also be responsible for a severe weather threat across the Eastern Seaboard on Tuesday. Heavy rain and damaging winds will be the primary threat.

Heavy Flooding Rains

NOAA’s HPC 2 day rainfall forecast suggests several inches of rain possible from the Lower Mississippi Valley to the New England States through AM Wednesday. A few spots could get 3″ to 5″ from eastern Tennessee to West Virginia.

Flood Watch

The National Weather Service has issued a FLOOD WATCH for areas shaded in green from parts of the Tennessee Valley to the Virginias. A widespread area of 1″ to 3″ is possible in this area with localized areas of 4″ to 5″.

Historic Sea Ice

The sea ice in the Arctic Ocean dropped below the previous all-time record set in 2007. This year also marks the first time that there has been less than 4 million square kilometers (1.54 square miles) of sea ice since satellite observations began in 1979. This animation shows the 2012 time-series of ice extent using sea ice concentration data from the DMSP SSMI/S satellite sensor. The black area represents the daily average (median) sea ice extent over the 1979-2000 time period. Layered over top of that are the daily satellite measurements from January 1 — September 14, 2012. A rapid melt begins in July, whereby the 2012 ice extents fall far below the historical average. The National Snow and Ice Data Center (www.nsidc.org) will confirm the final minimum ice extent data and area once the melt stabilizes, usually in mid-September.”
