Meteorologist Mark’s 5-Day Wx Concerns

Look for areas of frost once again tonight. This should be the last of the frost for a long while. Keep in mind we still have Blackberry winter to go, though! (ha)

Thunderstorms on Saturday are expected to stay below severe limits.

Meteorologist Mark’s Wx Discussion

I did my thermometer experiment again last night and the results were quite dramatic! My official low temp was 24 degrees. That’s from my “professional” thermometer, located about four feet off the ground and out in the open. The thermometer that was at ground level and out in the open (field) recorded a low of 22 degrees! My other thermometer that was located under the trees and near ground level recorded a low of 32 degrees. What a difference in temps on these clear, calm, and frosty nights!

Last night was likely the coldest night we’ll see until Fall! Don’t forget that we still have more cold spells to go, though. We haven’t had Blackberry winter yet!

I still don’t see any decent severe storm chances. Saturday’s storms should stay non-severe. The extended outlooks does show some decent storm chances the middle of next week, but there’s plenty of time to watch that.

Almanac for Yesterday

On This Day in Wx History

1997- Lightning strikes a 130-year-old red oak tree northeast of Lynchburg. Chunks of wood weighing as much as 175 pounds fly about 50 yards! One large piece of wood is embedded in the tail light of a car. The lightning follows the tree’s roots, digging a trench almost 3 feet deep into and under a house. Flying wood damages the home and 3 cars.

59 Days until Summer

Yesterday’s National Temperature Extremes

High:  93° at Death Valley, California and Phoenix, Arizona

Low:   -8° at Burgess Junction, Wyoming 

Today’s Tennessee Weather 

Much of the state will see lots of sunshine today, with some passing clouds for northern Middle and East Tennessee and the plateau. Abundant sunshine will warm highs around 60 degrees for most, with the plateau and northeast Tennessee holding in the low to mid 50s. Breezy north winds will make temperatures feel cooler.

Tonight’s Tennessee’s Weather 

Clouds will increase from the west, with showers developing for West Tennessee. Where cloud cover is thickest, temperatures will be warmest. That will lead to quite the temperature spread across the state, with lows around 50 in the west and lows in the mid to upper 30s in the east.

Tomorrow’s Tennessee’s Weather 

Showers are expected across West Tennessee, while clouds increase for the rest of the state. Mild weather has returned, with highs in the 60s statewide.

Today’s National Weather Map

Low humidity and gusty winds will fuel wildfire dangers across eastern North Dakota. That threat is also present for much of New Mexico, southeast Colorado, and southeast Arizona. Elsewhere, low-impact precip is expected in various areas of the country today.

Drought Monitor

The drought monitor is updated each Thursday. This is the latest map!

The drought out west….yikes…

For comparison, this is last week’s drought map.

NASA Nerdology 

During this week in 2002, NASA’s TRACE spacecraft captured this image of an X-ray flare. During its 12-year mission, TRACE spacecraft collected data on the Sun, such as the triggers for solar flares and the evolution of magnetic field structures.

You all have a great day and keep lookin’ up!
