October Nor’easter Snow Totals
October 30, 2011

A snow producing storm in October is rare. In Baltimore, measurable snow has been recorded only three times since the late 1800s … 1925 – 1940 – 1979.

This most recent storm produced only a trace (officially not measurable) of  snow at BWI-Marshall. This ties the “record” for October 29 that was set in 1952.

The nor’easter did produce significant, wet, heavy snowfall elswhere in the Mid Atlantic region. Below is a map with a sampling of snow totals in Maryland reported as of 10:00pm, October 29. (Added Sunday morning … A Sunday morning satellite image of the swath of snow laid down by the storm follows the snow totals map.) (Added early Monday….a false color, high resolution satellite image of the snow covered areas.)

The visible satellite images below clearly shows the snow laid down by the nor’easter. The Susquehannah and Hudson River valleys are easily identifiable in the snowpack. The false color, high resolution satellite image shows spectacular detail of the storm’s snow track. The color image was captured Sunday by NASA’s MODIS polar orbiting satellite. The black and white image was captured from the higher orbiting NOAA GOES satellite.  Maryland and regional snow totals are listed below the images.

Saturday Storm Update
October 29, 2011

The developing nor’easter continues to strengthen off the North Carolina coast and the Mid Atlantic region is experiencing a mix of rain and snow.

The late morning rain/snow line runs from northeast Carroll County, through western Howard County and into Virginia near Leesburg. The Baltimore metro area temperatures dropped into the upper 30s around 5am Saturday and have remained fairly steady since that time. The metro area received a wintery mix for a brief period of time with some slush accumulation but most of the precipitation has been rain with .52 inches of liquid measured since mindnight.

Source: National Weather Service (9:30am Saturday, October 29, 2011)

The morning surface map shows the storm center near Cape Hatteras. Circulation around the storm has been producing northerly winds over Maryland but as the storm center moves northward winds should veer more easterly for a period of time transporting relatively mild Atlantic air toward the Bay, keeping temperatures in the upper 30s to around 40 degrees, holding most if not all of the snow west of the metro area. Once the storm is off the mouth of the Delaware Bay winds should start to veer more northerly and then northwesterly, allowing the rain/snow line to move closer to the Bay for a brief period of time before precipitation ends during the evening hours.

The immediate Baltimore metro area remains on tap to receive a trace to 2 inches of wet snow by the time the storm ends. Just to the north and northwest snow totals could range from two to six inches where elevation increases and colder temperatures prevail in portions of Carroll and northern Baltimore Counties.

Rare October Nor’easter
October 29, 2011

A rare October nor’easter will be developing Saturday off the Mid Atlantic coast. With cold air in place over the region, this storm has the potential to generate some significant snow over a portion of the area.

 

Much of the I-95 corridor including the Baltimore metro area will see rain and a rain-snow mix. Higher elevations to the north and west will be colder and have a greater chance of receiving a wet, heavy snow.

The record snow for Baltimore for October 29 is a Trace in 1952. This would not be too hard to tie or break in this particular situation.

Computer models continue to show some inconsistancy from run to run on the fine details of the storm so adjustments to the snow total forecasts may still need to be made. Check out the latest information on wbaltv.com and tune in Lowell Melser and John Collins Staturday for the latest updates.

Weekend Snow Threat
October 28, 2011

RPM snowfall forecast as of 11pm Saturday, Oct 29, 2011

The first flakes of the 2011-2012 winter weather season may be headed this way.  Thursday evening computer models continue to show a developing snow threat for Saturday.  The cold front that went through Baltimore Thursday evening with wind gusts to 30 mph, dropped the temperature 18 degrees between 5pm and 11pm (from 62° down to 44°).  Cold air will continue to filter into the area Friday, as low pressure develops on the front to our southwest.  The low is forecast to move to a position off the mid Atlantic coast Saturday, bringing the possibility of a cold rain changing to wet snow as temperatures fall during the day.  Early estimates of snowfall accumulations are in the 1-3″ range, but heavier amounts are possible in the colder areas north and west of Baltimore.  What is unclear, is how the warm, wet ground will impact snow accumulations.  One thing to consider, however, is that even if the snow doesn’t stick to the ground, it might stick to colder surfaces, such as tree branches, decks and power lines.

Stay tuned for updates as the storm develops on Friday.

Denver Snow
October 26, 2011

Just wanted to pass along these pictures of snow in Denver. I had my little sister send them to me on her way to work. It began snowing in Denver Tuesday evening, and so far, they’ve gotten between 4″-6″ in the metro area alone, with even more in the foothills and mountains. But as you can see by the pictures, the snow is quickly melting because the ground is still quite warm from the warm weather earlier this week. Would you believe it was in the 80s in Denver on Tuesday?!? October snowstorms are actually quite common in Denver.

UPDATE: My sister just sent me another picture of the snow, this time from the Univ. of Colorado campus in Boulder, CO (which is northwest of Denver and higher in elevation)

Winter Outlook Dec. 2011 – Feb. 2012
October 20, 2011

The National Oceanic and Atmospheric Administration (NOAA) released their outlook for the upcoming winter months:  Winter Outlook.  The outlook covers the 90 day period from December 2011 through February 2012.  La Nina, cooler than normal water temperatures in the tropical Pacific Ocean, is expected to produce more wet weather across much of the northern United States, and drier than normal weather across the south.  A cold winter is expected over much ofthe upper Midwest and Great Lakes regions.  A warm winter is indicated for much of the Southwest, Southern Plains, and western Gulf Coast.

Here in Maryland, the La Nina pattern does produce a clear signal for our winter weather.  Our weather over the same 90 day period will be more prone to the North Atlantic Oscillation, a periodic fluctuation between high and low pressure over Greenland and the North Atlantic Ocean.  Therefore, there are equal chances of cold and warm weather here, as well as, equal chances that it will be dry or wet.

More Wet Weather
October 18, 2011

A new storm is coming together and it promises to be a wet one for the Mid Atlantic Region.

Source: NOAA/NASA

The overnight (Monday-Tuesday) satellite image shows a storm in the Plains and Midwest plus another storm in the southeastern Gulf of Mexico. They are expected to merge over the Mid Atlantic on Wednesday.

The surface forecast map above outlines the expected positions of the two storms on Wednesday morning.

Most of the rainfall will be coming up from the Gulf with possible rain totals in the one to two inch range. The heaviest rains will likely be east of the Bay.
