Meteorologist Mark’s Wx Thoughts (New!)

Guidance is shifting back away from snow on Monday. It still likes like we’ll see precip but much of that may fall during the day, when temps are above freezing. As darkness falls, assuming there’s some precip left over, we could see some light snow accumulation.

When models and guidance are this quirky, for this length of time, with a system it often means we’re not going to see much of anything from it. Sure, there are those rare exceptions when systems like this suddenly change in the model data and we’re back to forecasting snow. I’m just not seeing that happening with this system. This morning’s data would have been the point at which things would start to look really good for snow and that just didn’t happen. I thought for sure guidance would look better for snow this morning but it is what it is. There is a good chance that we won’t see anything but a rain/snow mix at best. This is a gulf low (albeit a weak one), so I will certainly keep an eye on things!

Wx Threats for the Next 7 Days

Wintry precip will threaten the area once again on Monday. Daytime temps are expected to be above freezing, which should keep us safe from wintry travel during those daylight areas. As temps fall in the evening, some light snow could fall, resulting in some light accumulation. Stay tuned for any changes. Confidence is low concerning snow chances and amounts.

Meteorologist Mark’s Snow Scale

On This Day in Wx History

1886- One of the coldest days in Nashville’s history — the high temperature tops out at 7 degrees, with a low of -8, making for a daily mean value of -1. All three are records.


Yesterday’s National Temperature Extremes

High: 79° at Santa Barbara and Van Nuys, California

Low: -14° at Gunnison, Colorado

Today’s National Wx Hazards

Accumulating snowfall can be found from Texas to Wyoming. An expansive winter storm! Elsewhere, freezing rain threatens areas along the Washington and Oregon border.

Tomorrow’s National Wx Hazards

Heavy snow threatens central Texas, with lighter snows falling just to the northwest. More snowflakes are flying for the northern Rockies and parts of the Great Lakes region.

 Weather Shots

I snapped this picture yesterday during the snow and it has now become one of my most popular photos ever taken! It’s odd because I just casually turned around and snapped the pic. I would have taken more time and care if I had known how popular it was going to be! (ha) This is my dad’s old smokehouse, the the corn crib to the right. And yes, that’s the Dish satellite in the left. A sign of the changing times, right?

NASA Nerdology 

I’m not sure skies will allow, but if the clouds can break, you will be able to see a planetary trio in the western sky about 45 minutes after sunset. Mercury and Saturn are actually in conjunction (like the “Christmas Star with Jupiter and Saturn). These three planets will do a close dance but you need your binoculars to really enjoy the show. I’ll try to remind you if this is visible this evening. It will be visible for the next few evenings, too.

You all have a great day!
