Meteorologist Mark’s Severe Wx Concern

Hay Wx Forecast

We’re looking mostly dry this week, though frontal passages on both Monday and Thursday evenings could bring a couple of showers to the plateau. The dry and cool weather coming this weekend looks to last for several days beyond this forecast. Widespread frost is coming Friday night to end the growing season area-wide.

On This Day in Wx History

2000– A cold snap brings several days of unusually cold weather to Middle Tennessee. The morning low at Crossville drops to freezing. That would be Crossville’s fourth daily record low temperature within five days.


Yesterday’s National Temperature Extremes

High: 106° at Rio Grande Village, Texas 

Low: 19° at Big Sky, Montana

Tropical Outlook

We’re still keeping an eye on that disturbance in the Atlantic. Models indicate the window of opportunity for development is going to start closing by tomorrow evening, as upper-level winds become to strong to support tropical development.

Today’s National Wx Hazards

An unsettled weather day in the eastern US, but hazardous weather is not expected.

Tomorrow’s National Wx Hazards

A quiet day, but look at all the snowflakes in the Northwest and along the US/Canada border.

 8 – 14 Day Outlook

Cool, fall-like weather looks to overspread much of the country in the 8-14 day outlook! Within that trough of cooler air, showers will be possible, as shown by the various areas shaded in green that indicate rain chances.



Weather Shots

I talk about this typhoon a lot during hurricane talks because it was the largest (in size) typhoon ever recorded. It was almost the size of the western half of the US! Typhoon Tip occurred 41 years ago today. China can be seen in the upper left of the screen.

NASA Nerdology 

Mars will be at its brightest this week, as the Red Planet lines up with Earth on the same side of the sun. This is called “opposition” and occurs every 26 months. If you recall, Earth and Mars made their closest approach last week and won’t be that close again until 2035. It’s always around opposition that space probes are launched toward Mars. The shorter the distance to travel the better! If you miss the launch window, you have to wait 26 more months to try it again. As our skies clear out this week, be sure and go out and look up. You can’t miss that big red “star” in the Southeastern sky (I’ll remind you, too!).

You all have a great day!
