The sun will come out, tomorrow!

today

Weather Headlines

–Skies should gradually clear out today

–The next rain chance arrives Friday

–Better rain chances arrive early next week with another arctic cold front

Main threats

No widespread hazardous weather is expected for the next seven days.

Summary

These low-level, stubborn clouds will be very slow to move out. They’ll likely try to hang around with us all day long. That will keep temps very chilly.

By tomorrow, the sun should be out in full force. That will feel and look very nice!

The next system arrives Friday but it is rather weak. Just look for some showers. Rainfall amounts should stay at or under 1/4 inch.

The next significant system arrives early next week. That is associated with a strong arctic cold front that will bring in some much colder air for next week. I’ll have more on that as we get closer to that time.

Baldwin’s 7-Day forecast

7day

Records

It was a snowy day in the Northeast on this day in 1989. Maine picked up nearly three feet of snow in just 24 hours. Winds gusted to over 40 mph.

On this day in 1982 it was certainly not a wintry day in Tennessee! Nashville set a record high of 79 degrees.

Tuesday Clues Day (New section that changes each day)

Is the old adage “red sky at night, sailor’s delight” based on anything meteorological? Does that offer any weather clues? Well, yes it does!

While it’s not 100%, a red sunset often foretells good weather. As the sun sinks lower in the sky, its rays are forced to shine through more atmosphere. If there’s a lot of dust in that atmosphere, the light will be redder. Dust in the atmosphere is from a stagnant atmosphere associated with high pressure. Since weather most often moves from west to east, this red sunset can forecast incoming high pressure. High pressure brings good weather.

NASA Knowledge

NASA scientists are working hard to better understand the dust storms on Mars. Such a storm caused us to lose touch with Opportunity, a rover that had been placed on Mars. Every decade or so, a series of violent dust storms break out across the Red planet. Within these enormous storms, dust towers can exceed heights of 50 miles! Some towers have been known to last for weeks. Some of these storms are as large at the United States!

As these enormous towers of dust rise, they carry with them water vapor. This leads to high, thin wispy clouds on Mars that eventually dissipate. The barrage of solar UV rays causes the water vapor to break up and dissipate. Is this how Mars lost all of its water? That’s what scientists intend to find out.

Before we can venture to Mars, we must gain a better understanding of these dust storms. Astronauts would be no match for these ferocious wind storms.

Pictured below: The yellow-white cloud in the bottom-center of this image is a Mars “dust tower” — a concentrated cloud of dust that can be lofted dozens of miles above the surface. The blue-white plumes are water vapor clouds. This image was taken on Nov. 30, 2010, by NASA’s Mars Reconnaissance Orbiter.

News

The Smokies picked up several inches of snow from yesterday’s event. The NWS in Morristown, TN shared this pic from Clingman’s Dome from sunrise this morning. It’d be nice to be high enough to be above the low clouds that shroud the plateau this morning! Of course, they’re also about 20 degrees colder than we are now! ha
