What is a "ShortWave"?

Also known as Shortwave Trough; a disturbance in the mid or upper part of the atmosphere which induces upward motion ahead of it. If other conditions are favorable, the upward motion can contribute to thunderstorm development ahead of a shortwave.

How I started...

I've been a weather hobbyist all of my life. As a child, I used to stand outside in the rain during thunderstorms just to watch the lightning. Back in the '70s getting weather information was a chore. I remember listening to NWS broadcasts during hurricane season and plotting these on a piece of paper. After moving to New England I finally bought my first real weather station made by Davis Instruments. I began to record daily weather data in a journal. I had a few people, where I work, who knew I was a weather nut, ask me to send them an e-mail on the weekend forecast. So two grew to five then 15, then 40, and now my Thursday weekend mail list reaches over 200+ people. I took some web programming classes in the late '90s and a few years after that RichLefko.com was born. I wanted to share my hobby with anyone who was interested, and I am quite overwhelmed with how many people seem to be interested. I've gotten so many "thank you's" for a variety of reasons..."saved my party", "saved my wedding", "saved my life." It's been fun and rewarding all at the same time.
Thanks for visiting RichLefko.com. Please tell your friends and family.

Rich's Local Weather Discussion:

12/11 - 7:56 AM: Very slippery roads outside this morning. We dropped below freezing just after midnight, so wet roads froze, then light snow covered them. Further south and east, a Winter Weather Advisory was expanded to all of NE MA as well as SE MA. Accumulating snow down there will end later this morning. Skies will gradually clear out today with much colder temps remaining below freezing. Cold tonight through Thursday night. By Friday clouds will be on the increase as another storm system that will track up the coast and to our west. We'll remain in the warm sector for this storm as well, which will bring rain once again to the region. We remain in an active weather pattern with the next system arriving around Tuesday. That one might bring snow. Stay tuned.

SYNOPSIS...NH/ME
Today will feature clearing skies but cold temperatures, with
highs right around the freezing mark in many areas. An active
weather pattern looks to continue this weekend with low pressure
moving up the coast delivering a chance of heavy rainfall
perhaps with a brief period of mixed precipitation at the
start. Windy and cold conditions will likely follow in the wake
of the low for Sunday into Monday. Another low pressure system
will approach from Monday night and Tuesday and that one may
contain more wintry precipitation.

SYNOPSIS...MA
Rain changing to a period of moderate to even briefly heavy
snow will make for a difficult morning commute across much of
the region. Snow is pretty much over by lunchtime, but a
reinforcing cold front will bring dry but even colder weather
tonight. Large high pressure will bring cold and dry conditions
Thursday and Friday. Developing low pressure across the
southeast U.S. will shift up the coast with the potential for
periods of heavy rain Friday night into Saturday, possibly
beginning as a period of light snow across interior
Massachusetts. Drier and cooler weather returns Sunday into
Monday. Another storm may impact the region Monday night into
Tuesday with snow or rain.

* Snow this morning resulting in a messy morning commute

* Snow ends from west to east by lunchtime, except may linger into
early afternoon across the Cape/Nantucket

LONG TERM /THURSDAY THROUGH TUESDAY/...
Highlights...

* Dry and cold conditions Thursday

* Southern stream system works up the coast Friday through
Saturday, bringing milder temperatures and the potential for
heavy rain & localized flooding especially late Friday night
and Saturday. Melting snow may increase flood risks.

* Leftover rain/snow showers linger into early Sunday. Drying out
and seasonably cold on Monday before next system arrives on
Tuesday.

12/10 -  6:25 PM: Rain continues to move across the region at this hour. Temperatures are cooling down with the current temp at 41° here in Peterborough, NH. A cold front is crossing the region this evening. That front will bring a band of snow through New England, but no one seems to be sure who gets what, except SE MA. Here in NH this band forms too far south especially with the dry, colder air in place. I don't think we'll see much snow, if any, here in Southern NH. Further south there is an expectation of snow with the heaviest falling in SE MA. A Winter weather Advisory can be found for this region here, with estimated snowfall totals. The bad part of this forecast is the timing. That snow may be falling during the Wednesday morning commute. Clearing on Wednesday with some snow showers, squally in nature, around as a reinforcing shot of cold air arrives. Much colder Wednesday-Thursday, but the cold doesn't hang around very long. The next system arrives Friday night, perhaps starting as a mix, but this looks like another rain event.

SYNOPSIS...NH/ME
A cold front will cross the area overnight with colder and drier
air moving into the region. A weak storm system will pass well
offshore overnight, and while it will spread snow to the
northwest of its track it looks to remain too far southeast.
Wednesday will see clearing but cold temperatures, with highs
barely reaching freezing. An active weather pattern looks to
continue this weekend with low pressure moving up the coast
delivering another chance of heavy rainfall.

SYNOPSIS...MA
A strong cold front crosses the region this evening, followed
by colder temperatures with showers changing to a period of
accumulating snow later tonight into Wednesday morning,
especially south of the Massachusetts Turnpike where a
significant impact may occur during the morning commute. Large
high pressure will bring cold and dry conditions Thursday and
Friday. Developing low pressure across the southeast U.S. will
shift up the coast with the potential for periods of heavy rain
Friday night into Saturday, possibly beginning as a period of
light snow across interior Massachusetts. Drier and cooler
weather returns Sunday into Monday. Another storm may impact
the region next Tuesday with snow or rain.

SHORT TERM /MIDNIGHT THROUGH 6 PM WEDNESDAY/...
* Accumulating snow expected late tonight into Wed AM, with
highest amounts south of the Pike

* Significant impact to Wed AM Rush hour possible, especially
across parts of NE CT, Rhode Island and Southeast MA

LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
Highlights...
* Dry conditions and colder than normal temperatures on
Wednesday night and Thursday

* Temperatures moderate on Friday as next weather system brings the
potential for heavy rain & localized flooding late Friday into
Saturday. Flooding risks may be exacerbated by snowmelt.

* Leftover rain/snow showers linger into early Sunday. Drying out
and seasonably cold on Monday before next system arrives on
Tuesday.

Regional Weather Discussion ...

The combination of falling temps overnight and some light snow in southern NH will likely result in slippery spots for the morning commute. Beyond that, the weather pattern turns more tranquil until the weekend.

Any morning light snow in southern NH, total of a coating to 2 inches in areas from Concord and Rochester south, will give way to some sun as the day wears on. Temps will only top off in the mid 20s north to the low to mid 30s south with a light breeze.

A bright and cold Thursday will be followed by a partly sunny and slightly milder Friday, but still in the 30s.

The next system brings more rain with some mixing initially up north late Friday night into Saturday before we go back to partial sunshine for Sunday and Monday.

These "discussions" are from the NWS, or WMUR Manchester NH, or me.
