Glossary of Terms used by the folks who
regularly comment in the CWG blog

Bust

a forecast that turns out to be significantly wrong.  In the winter, it is a pejorative term used by sno bros (see below) towards a weather forecaster who commits the unpardonable sin of predicting snowfall that fails to materialize.

CTB

Colder Than Barrow (Alaska), which does occur in the Washington DC area occasionally. Mildists dislike this occurrence.

Coldist

likes all seasons colder than average. Often on the receiving end of quips like, “move to Canada!”

Conversational
Snow

light snow that looks pretty but doesn't accumulate, except for a coating in a few spots.

DC snow hole

the propensity for the city of DC to get less snow than the surrounding metro area.

Extremist

likes cold winters and hot summers.

GANGle (derivative of Google)

[transitive verb] To post a question in the CWG blog to obtain information about a topic, from the collective brains of its awesome commentors.

the Gravel

gravel that may or may not be under the weather station at National airport, that regular commenter “eric” blames for skewing temperatures higher.  (Note that commenter “tkurkowski” thinks that continuous jet turbine exhaust doesn’t help the accuracy either.)

Grow bro

a gardener, male or female, who evaluates weather based on its effect on horticulture.

Individucast

a forecast for a very specific, personal, time and place.  Typical individucast request: I’ll be driving from Silver Spring to Reston at 3:15 pm.  Will the snow have started sticking at the corner of St. Francis Street and Bluemont Way when I get there?

Mildist

likes cool summers and warm winters.  Mildists love spring and fall.

Model hugging

a) adjusting the forecast wildly with each model run. Often involves  picking the model that predicts what the hugger wants to have happen, and sticking with it over all the other models.
b) what quarterback Tom Brady does at night

Nowcasting

forecasting the weather as it happens.

Polite rain

light to light/moderate rain with no lightning, wind,
or hail.

Radarcasting

forecasting based on extrapolating current radar returns.

Seasonalist

likes weather to be appropriate for the season. Likes temperatures and precipitation to be as close to normal as possible.  

Snow bro

a snow lover (male or female).  If you have a snowy avatar, think a snowy landscape is just about the prettiest thing ever, consider being snow-bound a good thing, or can’t help but try to make a snowball when you’re out in snow, you might be a snow bro.  Note that snow bros are not necessarily coldists, and coldists are not necessarily snow bros.

Snowfanity

dirty words snow bros HATE TO HEAR around snow events, i.e, rain, sleet, freezing rain, slush, warm air aloft, warm surface layer, urban heat island, snowhole, changing to rain/sleet/freezing rain, melting, melt on contact, etc…

Unicorn
snow

mythical snow reportedly seen when the air temperatures at the surface are too warm at the start of the event, but heavy rates of precipitation magically drop the air temperatures to below freezing, allowing accumulation.

Warmist

likes all seasons warmer than average.  Warmists are used to hearing, “move to Florida!”

the Wedge

 – aka. “Cold Air Damming (CAD)” – No, this is not a term invented by haters of cold weather.  The “wedge” is a notable weather phenomenon where cooler, stable, maritime air, flowing clockwise around the southern periphery of a New England/Western North Atlantic surface high pressure area, runs up (wedges itself) against the eastern side of the Appalachian mountains and is pinned there by the northeasterly surface winds.   The longer the duration and fetch of the northeasterly wind, the stronger and more persistent the wedge.  The moist nature of the air creates an overcast sky and sometime fog.  Although fairly shallow in height, maybe a couple of thousand feet thick, the wedge leads to cooler surface temperatures and can create temperature contrasts of 30  F over a horizontal distance of only 50-75 miles. 

While wedges can occur in any season, they are most common in spring.   Winter “wedgies” can induce overrunning, where warm moist air from the south is lifted over the colder, denser air at the surface.  If this surface air is below freezing, an ice storm can result.  Many a sunny and warm forecast has been busted by the wedge!

"The Wedge Always Wins" (abbreviated TWAW) is a reminder that the cold air will invariably linger much longer than forecast.

Wishcasting

forecasting based on what you wish to have happen.
