Meteorologist Mark’s Wx Concerns
Confidence is increasing that we will see around an inch of snow areawide Sunday night to Monday. If trends continue, I’ll be bumping that up to the 1-2 inch zone.

Meteorologist Mark’s Wx Discussion
A big winter storm will begin to evolve to our east by tonight. We’ll see our winds pick up as that system gains momentum. For us, it will mean rain. For those to the east of us and in the mountains, it means lots of snow and ice. As the system moves away from us, another weaker system will swing in from the north. That system will bring us our snow chances. So, the main action will have moved off to the east but there should be enough energy left over to bring us some light snow.
I wouldn’t be surprised if snow falls off and on throughout the day on Monday. That could even lead to some additional accumulation. Some guidance is even suggested flurries linger into Tuesday morning.
Our next storm system arrives by Thursday and it looks to be rain.

Almanac

Yesterday’s National Temperature Extremes
High: 80° at McAllen, Weslaco, & Rio Grande Village, Texas
Low: -23° at Mount Washington, New Hampshire
Today’s National Wx Hazards
Mixed wintry precip arches from Minnesota to the Upstate of South Carolina as the day goes along. Accumulating snow can be found in a band north of that swath of wintry mix. Farther west, snowflakes fly on the peaks of the Rockies.

Tomorrow’s National Wx Hazards
A significant winter storm evolves from North Carolina to New York. Freezing rain, sleet and snow will fall across those areas and make travel nearly impossible. A swath of accumulating snowfall can be found from the Upper Midwest to the Jersey Shore. Much farther to the west, flooding rainfall threatens the northern coast of California (part of the Big Sur highway washed out this week!).

Weather Shots
I snapped this pic yesterday from the backyard. What a beautiful sunset it was! We’re so fortunate to live in Tennessee, where winters are quite bearable!

NASA Nerdology
It was during the final week of January of 1920 that President Woodrow Wilson appointed Orville Wright to NASA’s predecessor, the National Advisory Committee for Aeronautics (NACA). NACA was created to “supervise and direct the scientific study of the problems of flight, with a view to their practical solution.”
If only they could have known then that NACA would evolve into NASA and do the most incredible things! I wonder what these gentlemen were thinking would come of NACA? It was 1920, after all. I wonder if they even imagined we’d be going to the Moon?
