weather outlook across the nation looks quite active through the week.
Our first storm wraps up over the Northeastern part of the country with
significant winds and some snow along the coast. The second storm begins
to take shape in the western part of the country with heavy rain along
the coast and heavy snow for the higher elevations. The storm system
will eventually move into the into the middle part of the country with
rain and snow.
to NOAA's HPC 5 day precipitation forecast, the heaviest precipitation
is expected to be across the western part of the country, especially in
the higher elevations. Some spots through the early weekend could see as
much 5" to 7".

webcam from Boston, MA earlier Monday looked quite serene. This is all
going to change heading into Tuesday and Wednesday as our big storm
Here's another spot that will look quite different by the middle part of the week. Back to that in a moment.
Signs of Spring in New York
about this... Nice to see the birds migrating again! Thanks to Andy
Walts for this picture, which shows a bunch of Canadian and Snow Geese
Here's another spring view of roses in bloom in Florida.
This is what Eileen had to say about her flowers in Florida!
March Temp Anom
certainly has been a cold month so far. Note the blues and greens
across much of Canada and the eastern two-thirds of the nation. This is
where temperatures have been much colder than average.
Monday Morning Snow in Minnesota
quick moving clipper system moving through the Midwest on Monday was
responsible for light snow accumulations in many areas. This was the
view from Shakopee, MN, which is home to Valley Fair the amusement park.
Monday Morning Lows
a look at how cold it was on Monday morning. These numbers look more
like something we'd see in January, not late March! Good grief!
Rapid Storm Intensification
same clipper system that was responsible for light snow accumulations
across the Midwest will aid in the rapid intensification of a low
pressure system off the East Coast Tuesday into Wednesday. The rapid
intensification will go through a process known as "Bombogenesis" or at
least a 24mb drop in 24 hours.

Here's the storm system by midnight Wednesday as the two storms have merged east of Virginia.
how much more intense the storm looks by Wednesday afternoon. The good
news is that the storm will be moving quickly, so yes we expect lots of
wind and some snow, but it will move quickly out of the region by

Boston Snow Potential
Boston snow meteogram doesn't show quite as much snow for the cities as
what it was showing in previous runs. The average between the models is
around 2" to 3". The maximum is around 4.5", but the minimum is nearly
