An unsettled pattern

today

Weather Headlines

–Clouds and winds increase on Tuesday, with overnight rain

–Rain clears out by Wednesday afternoon

–Thanksgiving and Black Friday looking cloudy but mild

–Weekend storm system to bring wind, rain, and thunder

Main threats

>>Strong winds will be likely for our Tuesday. Secure any loose objects you have outside.

>>Strong winds and heavy rain will be possible Saturday (monitoring)

Summary

We have a very pleasant Monday in store for us! Be sure and enjoy the nice weather.

By tomorrow, winds will be increasing, along with cloud cover. Some winds could gust to 40 mph. Rain will move in, mainly after sunset, along with a rumble of thunder. That rain should be out of here by Wednesday afternoon.

As of now, both Thanksgiving and Black Friday are looking mostly cloudy (though there could be some peaks of sun) and mild. There are some indications we could see a shower or two across the plateau but I just left it out for now, due to the slim chances of that.

The next big system blows in here on Saturday. That system may hold off until Saturday night but that’s too far off to know for sure on that. That system will likely produce more gusty winds. We may even have some stronger storms to deal with. I’ll keep an eye on that.

It looks like a big push of cold air will move in to start off December with. We may see some snow flurries by Sunday evening with that cold push of air, but right now it doesn’t look like a big deal. I’ll keep an eye on that too!

Baldwin’s 7-Day forecast

7day

Records

It was a cold, cold morning across Tennessee on this day in 1950. With several inches of snow covering much of the state, low temps were able to drop to incredible levels for this morning. Clarksville was two below zero, while Nashville was one below zero. Both of those are record lows for the month of November for those cities.

The historic storm that brought those cold temperatures was still barreling up the East Coast. Wind gusts to 100 mph were recorded in Connecticut, as well as 110 mph gusts in New Hampshire. The observatory on Mount Washington, New Hampshire recorded a wind gust of 160 mph!

Ablation

The process of being removed, especially in reference to snow and ice. The opposite of accumulation.

WeatherTAP WeatherFACT

Snow ablation can occur on really cold, dry nights. On nights when there is snowpack and temps get bitter cold, some snow will evaporate into the cold, dry air. We call this ablation. This happens a lot in the arctic areas and even with Lake-Effect snowpack.

NASA Knowledge

NASA has an ambitious project planned that will map rising sea levels. By 2030, we will have 40 years of sea-level data.

“If you think about it, global sea level rise means that 70% of Earth’s surface is getting taller — 70% of the planet is changing its shape and growing. So it’s the whole planet changing. That’s what we’re really measuring.”

Along with measuring sea level rise, the mission will provide datasets that can help with weather predictions, assessing temperature changes in the atmosphere and collecting high-resolution vertical profiles of temperature and humidity.
