Winter Weather

FIRST SNOWFLAKES OF THE SEASON

NAM-NEST Precip type forecast 2 PM  (Click on image for a larger view.)

from Monday …

We have a chance of seeing the first snowflakes of this season early Wednesday morning. A weak upper air disturbance (clipper system) will move through the Philadephia area between 6 AM and 9 AM Wednesday morning.

Snow flurries are likely but most areas will either get no accumulation, or a light coating at most. Current water equivalents are very low, about 0.03 inches.

If this sort of non-event were to occur later in the season, it might not even merit a blog posting, but being the first flakes, I thought I’d get into gear.

There are some differences in model timing with tonight’s NAM and NAM-NEST having the this occur later in the morning. Stay tuned.

Basic Weather Facts

GREAT WEBSITE TO LEARN ABOUT WEATHER

I spend all too much time searching and viewing weather information sites on the Internet.

Today I stumbled upon an impressive weather web site (from our very own weather.gov) for anyone wishing to learn the basics of atmospheric science and weather forecasting.

Great for for kids.. and adults too! Hey, I learned (and re-learned) a few things!

It’s from the National Weather Service- NOAA, and it’s called “JETSTREAM” — https://www.weather.gov/jetstream/

It’s a very comprehensive, extremely well-designed site that’s structured as a comprehensive introductory course to atmospheric science, somewhere between high school and college level. I think even younger kids into science would enjoy it.

It beautifully explains and illustrates things like jet streams, vorticity, upper air charts and weather. It’s the real deal and it’s basic weather science information as it should be presented. I think it could inspire more than a few budding meteorologists. I would have loved to have had access to this as a kid.
