WXman57 I am so ready for the real Spring. Up here in Dallas this weekend so I might get lucky and see more snow.

Well, let's see if the 18Z GFS sees any spring on the horizon. Here are a couple of meteograms. As you can see, more days above 70, but nothing near 80 for the next 2 weeks. That's unbelievable, only a couple of 80 degree days through early April. And I do think Sunday will be overcast much of the day, so Monday should be the colder morning (35).

How do you decipher a storm system's intensity, wxman57, wxdata, srainhoutx, Ptarmigan, Mr. T? Are there certain numbers that indicate how strong and weak that it is?

Aunt called from Sanger (Just north of Denton.....which is north of Dallas Fort Worth) said they were getting snow again, big flakes.
She calls every time it snows up there now since our December 4th snow event.......just to rub it in, and she's rubbed it in a lot this winter.
For the love of everything decent in this world please bring on SPRING.
I truly HATE cold weather now.

It was still snowing in Dallas area this morning. Big problem was the wind and visibility. My brother reported almost 4 inches of snow in Rockwall. I was supposed to meet him and my sister in Buffalo this AM to give him a car (his got wrecked thanks to an unidentified 18 wheeler losing its wheel) but we had to cancel because the road conditions were so bad up there.

First of all, are we all enjoying this first full day of spring? It's so nice to be done with all that cold, windy weather, isn't it? Anyone heading to the beach today to get some sun?
As for determining a storm's intensity, we look at its reflectivity in dBz. The more reflective, the stronger the storm. And we look at vertically integrated liquid (VIL) values. And we can look at Doppler velocity data to find evidence of rotation. The reflectivity and VIL values that determine severity do change a bit from season to season. Most modern radar programs help out with the determination with built-in algorithms to identify a severe storm by indicating rotation and hail size.

It is too cold to go to the beach right now, you got me thinking.
Normally, it should be warm by now. I remember last year at this time, it was.

The snow was great in Dallas and I am glad I got experience another snowfall. Driving out of Dallas was dangerous with the snow/slush covered bridges. Lots of wrecks. Glad to be home and very ready for real Spring.

What precisely/specifically is dBz?
