Winter 2013-14 Thread — Northern Hemisphere (snowy, warm, ice, record)

[Mac15]

How does that happen?

It never happens here. When a warm front comes in no matter how cold it is temps still rise rapidly.

In 2010 it rose from -10c to 5c in like 3 hours.

Here's the current temps (numbers) & 850mb temps (shaded background). If you're below that line and your surface temp is below freezing that means Freezing Rain or sleet will fall. Take a look at some areas still in single digits and teens!

It's 11°F here meanwhile the temp above my head at 4000 feet is above freezing. NOT GOOD

There's a spot in NW NJ at -2°F with positive 850 hPa temps. Rain at -19°C? Sounds fun! Or not. But these are under clear skies, right? Once the clouds move in, the temp will probably rise?

Snowpack holding temps down. Some areas still got over half foot of snow on the ground. I got 4" here and its been cloudy and still at 19°F. The dense cold air is also trapped at the surface from overnight.

That -2 you saw is Sussex, NJ. Now at 4F above. http://forecast.weather.gov/MapClick...6#.UsllM2Uo74g

Let me grab the sounding for them.

RAP13z showing the inversion at Sussex, NJ at 10am. (no moisture). That's A 16 degree rise with height within 2000 feet. WOW! Note is back below freezing above 6000 feet. So the warming is only at the mid levels of the atmosphere.

Snow is light right now in N Indiana, but will pick up by afternoon. With highs winds tomorrow, would not be surprised to see blizzard conditions in some spots.

Seems winter 2013/14 will be a mild one though I'm sure its going to snow at some point.

Speaking of St. Louis, snow forecast now 8"-13", temps hit high of 18 at 10 a.m., falling to 7, tomorrow HIGH of -3.

This is St Louis, not Minneapolis.:

This storm must have them a bit confused, just saw another forecast of 6 to 13. Lot of leeway there.

I'm getting freezing rain. Temps are 26° here. That's ice falling! Hope everyone is in tune with weather as we all should ALWAYS be.

All models hint om a resurgence of Arctic air (not as severe) for the Midwest in the 11-16 day time frame
