Meteorologist Mark’s 5-Day Wx Concerns

Meteorologist Mark’s Wx Discussion

If you notice on the almanac below, our rainfall deficit continues to grow. With 0.75 – 1.0 inch of rain coming with this week’s systems, we’ll be keeping even (hopefully). Next week is looking unsettled, but it’s unlikely that rainfall in that period will give us a big jump on rainfall. Hopefully, that changes. Let’s hope we don’t get too dry this spring. Plus, some of us really need the rain to wash pollen out of the air before we choke to death (ha).

Both today and Thursday’s storms are expected to stay below severe limits, though gusty winds and small hail can’t be ruled out. We’re certainly not looking at a widespread severe weather threat. That’s unusual for an unseasonably warm April day in Tennessee, especially with a “cold” front coming through. But, we just don’t have the atmospheric dynamics for a severe weather situation and that’s the most important ingredient of all.

We’ll have to keep an eye on next week’s unsettled pattern. Hopefully it just yields some nice April showers.

Almanac for Yesterday

On This Day in Wx History

1928 – A coastal storm produced tremendous late season snows in the Central Appalachians, including 35 inches at Bayard West Virginia, 31 inches at Somerset Pennsylvania, and 30 inches at Grantsville, Maryland. High winds accompanying the heavy wet snow uprooted trees and unroofed a number of homes. The storm caused great damage to fruit trees and wildlife.

Today’s Tennessee Weather 

An unseasonably warm day is in store for the state, with clouds increasing as we go through the day. Those clouds will lead to a chance for a few showers and thunderstorms across West and Middle Tennessee, especially during the afternoon. Breezy south winds and sunshine will keep temps in the 80s statewide.

Clouds will continue to thicken up in the overnight hours, which will keep nighttime low temps in the 60s statewide. A few showers or thunderstorms are possible across mainly West and Middle Tennessee.

Tomorrow’s Tennessee Weather 

Showers and thunderstorms will affect much of the state by day’s end. Thankfully, widespread severe storms are not expected, though one or two storms could contain gusty winds and small hail, especially across West Tennessee. High temperatures will once again be unseasonably warm.

Today’s National Weather Map

Strong to severe thunderstorms will threaten two separate areas of the country today. The first is across the southern plains, where you might expect such storms in April. All modes of severe weather are possible there, especially across the Texas portion of the threat area. Extremely large hail is also a noted threat. Folks from central Texas to southern Indiana will also need to be aware of a flood threat, as well.

A lesser threat, but a threat nonetheless, exist across mainly western Pennsylvania. All modes of severe weather are possible there, as well, though not to the degree as we’ll see in Texas today.

Drought Monitor

The drought monitor is updated each Thursday.
