48-Hour WX

Seven-Day Forecast

Daily Forecast Summary

Today: A very foggy morning will give way to mostly cloudy skies as we go through the day.

Monday – Tuesday: Partly to mostly cloudy skies. Rain develops Tuesday night.

Wednesday – Thursday: Rain and thunderstorms. Rainfall could be heavy.

Friday: Partly to mostly cloudy skies. Turning cooler.

Saturday: Mostly sunny and cooler.

Meteorologist Mark’s Severe Wx Concern

My concern has increased for Wednesday and Thursday, owing to recent forecast changes that could bring heavy rainfall and strong storms to our area. I’m monitoring this changing forecast very closely.

Threats

Thunderstorms associated with a strong storm system and the remnants of Zeta could bring heavy rainfall to the plateau by the middle and end of the week. The heavy rainfall may also be accompanied by stronger thunderstorms. I’ll be monitoring all of this very closely.

On This Day in Wx History

1955- Despite a frigid morning low of 21 degrees, Crossville’s temperature jumps 42 degrees to top out at a pleasant 63 degrees by the afternoon.

Almanac

Yesterday’s National Temperature Extremes

High: 93° at Death Valley, California 

Low: -1° at both Neihart and Mountain, Montana

Tropical Outlook

Earlier this morning, the National Hurricane Center determined that the area of low pressure in the Caribbean that we’ve been monitoring has now developed into Tropical Storm Zeta. The storm is expected to become a hurricane by Monday night. The current forecast track takes the storm to the northern Gulf Coast by Wednesday. As you can see, the storm then seems to aim for Tennessee by the end of the week and that is causing our forecast to undergo some changes. I’ll be watching this very closely.

Today’s National Wx Hazards

Cold air slips southward onto the plains, bringing accumulating snowfall to many areas. Farther west, folks in California deal with another dangerous day of wildfires.

Tomorrow’s National Wx Hazards

Cold air plunges into the central and southern plains, bringing ice to western Texas and Oklahoma, with snow (some of it heavy) falling across the central plains. Meanwhile, a wildfire danger increases once again for California.

 8 – 14 Day Outlook

The first week of November is trending drier and warmer for much of the country.

The Sunday Story

The Winter Outlook

Trying to forecast a winter-season outlook is always a challenge. Some folks rely on weather folklore, though I find much of that to be unreliable. Perhaps folklore worked better in the past?

Each Autumn, NOAA issues their outlook for the winter and it has proven to be a rather reliable outlook. Sure, circumstances change and throw the outlook off from time to time, but overall, the outlook proves useful. 

NOAA doesn’t base their winter outlook on Woolly Worms, acorn crops and so on. NOAA’s outlook is based on global atmospheric and oceanic patterns and how they are expected to evolve in the coming months. 

NOAA’s outlook predicts a good chance of a warmer than usual winter for the plateau. That’s not to say there won’t be cold spells, but the overall winter is looking mild. That does not bode well for snow lovers.

The good news is that precipitation is looking neither above nor below normal. Hopefully, that means we can avoid conditions getting too dry or too wet. Water tables are very high across the region these days, so groundwater should be in good shape through the winter months. 

It is worth noting that mild winters often lead to more severe thunderstorm chances. A La Nina pattern is expected to persist through the winter and spring. Anytime a La Nina pattern develops, our risk for severe storms increases a bit, too. 

While a mild winter looks to be in the cards for the plateau, there will certainly be some cold snaps from time to time. Keep in mind that all it takes is the cold air meeting up with moist air a time or two to make for some bouts of wintry precipitation. 

I say this every year but it’s worth repeating. Always prepare for the worst but hope for the best! 

You all have a great day!

Meteorologist Mark’s Severe Wx Concern

Threats

Hazardous weather is not expected over the next week to ten days.

On This Day in Wx History

On this morning in 1981, Crossville recorded a morning low of 25 degrees. That tied the record low for this date.

Almanac

Yesterday’s National Temperature Extremes

High: 100° at Falcon Lake, Texas 

Low: -11° at Hinsdale, Montana

Tropical Outlook

Hurricane Epsilon continues to spin out to sea, while an area of disturbed weather in the Caribbean now gains our full attention. That system is expected to become Tropical Storm Zeta by the end of the weekend. The storm could threaten parts of the Gulf Coast early next week. When we get Zeta, we will tie the record-breaking 2005 season for most number of named storms in a single season.

Today’s National Wx Hazards

Accumulating snowfall can be found across the northern plains today, with some areas breaking October snowfall records (if they haven’t already!).

Tomorrow’s National Wx Hazards

More snow for the northern plains!

 8 – 14 Day Outlook

The pattern continues to look dry in the 8-14 day outlook, but temps are looking milder for much of the country. This is for Halloween and the first week of November.

NASA Nerdology 

NASA has confirmed that the mission to land on Asteroid Bennu has been successful! The probe landed for several seconds, collected some dust and pebbles, and has now stowed away the sample for a safe return trip to Earth. The sample will arrive back here in 2023.

You all have a great day! Wish me luck, as I run the Oak Barrel half marathon in Lynchburg, TN this morning!

Friday Night Storm Update

Showers and thundershowers are making their way across parts of the plateau at this hour. Other activity can be found all across Middle Tennessee. These storms are below severe limits and are expected to stay that way overnight. Many of us may hear some thunder and get some heavy downpours of rain, but severe activity is not expected.

The current radar shows plenty of showers and thundershowers to come. I highlighted the borders of Putnam, Cumberland, Overton, and Fentress Counties for perspective. You all have a good night!

On This Day in Wx History

1761 – A hurricane struck southeastern New England. It was the most violent in thirty years. Thousands of trees blocked roads in Massachusetts and Rhode Island.

Almanac

Yesterday’s National Temperature Extremes

High: 100° at Rio Grande Village, Texas 

Low: at Big Sky, Montana

Tropical Outlook

Hurricane Epsilon continues to weaken and move out to sea, but we have something else to be concerned with. Development of a tropical depression now looks likely in the Caribbean by the end of this weekend. What’s worse is that it now looks like it will head for the Gulf, rather than out into the Atlantic. I’ll keep you posted!

Today’s National Wx Hazards

A cold front will set off some strong to severe storms across northern Indiana and southeast Michigan today. Behind that front, a big winter storm will be developing across the Northwest, bringing significant snowfall to many of those folks.

Tomorrow’s National Wx Hazards

Today’s winter storm spreads eastward and across the northern plains and Upper Midwest. Some October snowfall records are sure to fall.

 8 – 14 Day Outlook

The pattern in the 8-14 day outlook looks dry for a great many of us in the US. Temps look to be trending warmer in the western US, while staying cooler in the eastern US (with the exception of Florida). Please note that this outlook will change for the Southeast if we see tropical development in the Caribbean this weekend (and that development is looking likely).

I had an absolute blast attending Burks Elementary School in Monterey yesterday to talk hurricanes. We even made a hurricane in a bowl! The kids were great and all four Fourth grade classes were just amazing. I can’t wait to be invited back!

NASA Nerdology 

The first pictures from the surface of another planet were taken on this day in 1975! The Soviet spacecraft Venera 9 touched down on the hot surface of Venus and returned this panorama of the rocky surface, along with atmospheric data, before losing contact 53 minutes later.

You all have a great day!
