Tornado Watch for Part of West Tennessee

Friday, September 22nd, 2006

A tornado watch has been issued for the western part of West Tennessee, much of Arkansas and northwest Mississippi until 7:00 pm CDT. This watch replaces the previous watch from this morning that had included Hardin County. Middle Tennessee is not included in the current watch box.

Warm and moist air from the Gulf of Mexico has moved northward into the watch box area because of strong surface winds from the south. Winds aloft are blowing from the southwest with increasing speed. That twist of winds with height can provide tall thunderstorms enough spin for isolated tornadoes. Instability (warm, moist surface air underneath cooler air aloft) combined with a stationary front in Arkansas should allow thunderstorms to build today in the watch box area. The main threats will be isolated tornadoes, large hail and gusty wind.

Although Middle Tennessee has the spin necessary for severe weather, we’re not included in this watch box because we lack the surface instability. As Jeff mentioned this morning, the western edge of Middle Tennessee is included in the slight risk area on today’s severe weather outlook, but we anticipate that most of today’s severe weather will occur west of the mid-state. Check back with us for any changes through the day.

Storm Update

The Storm Prediction Center has issued a rare PDS (Particularly Dangerous Situation) Tornado Watch for West Tennessee and Central Arkansas. The watch is in effect for a long time, all the way to 7pm tonight. It is unusual to see a PDS in September especially one that runs all day long. There are going to be some major tornadoes today to our west. The strong storms could race into western Tennessee later this afternoon and early evening. We’ll be watching the event unfold and keeping an eye to our western edges.

There is also worry about tomorrow…
(from the National Weather Service Office in Old Hickory)
DAYS TWO THROUGH SEVEN…SATURDAY THROUGH THURSDAY…

AN APPROACHING COLD FRONT WILL PRODUCE SCATTERED THUNDERSTORMS
IN MIDDLE TENNESSEE ON SATURDAY. THUNDERSTORMS WILL BECOME
NUMEROUS SATURDAY NIGHT AND EARLY SUNDAY…AS THE FRONT SWEEPS
THROUGH. SOME STORMS COULD BECOME SEVERE…WITH DAMAGING WINDS
…LARGE HAIL…AND ISOLATED TORNADOES.

Lisa will assess the situation for you tonight, Justin will update you on the storm risk tomorrow morning; Saturday is one of those weather days that you need to be dialed into.

Stormy Weather

Friday, September 22nd, 2006

Winds have picked up; rain and storms have already been moving over middle Tennessee this morning. The rain and storms continue today along with brisk south winds. The rain activity should let up some tonight for Friday Night Football but it’ll still be windy and mild. Tomorrow we again have scattered storms and windy conditions in the forecast as the temperature gets up in the mid 80’s. A cold front moves over Saturday night late; that front could fire up some severe weather late and into the overnight. By Sunday afternoon things should be clearing out. Below is the severe storm risk for today, it includes the western half of our area.

Warm, Windy, Dodging Rain

Thursday, September 21st, 2006

Winds will pick up out of the south at 15-25mph… gusts to 30-35 Friday afternoon through Saturday.
Keep your umbrella handy. Scattered showers or t’showers around the first half of Friday… hopefully, dry by Friday night.
We can’t rule out an isolated shower or storm Saturday but most of the action will come with the front late night Saturday into early Sunday morning.

Here’s a look a your football forecasts:

Little Warmer for Awhile

Thursday, September 21st, 2006

The winds turn to the southeast today and tonight; we’ll have high clouds and highs in the mid-70’s today but tonight instead of lows in the 40’s we’ll bottom out in the low 60’s for the metro area. Big difference! It won’t last however, Fall weather will win the season. Tomorrow and Saturday we’ll actually enjoy 80 degree weather as the it becomes a little breezy as a cold front approachs. The rain chances really start to show up tomorrow afternoon; about a 40% chance tomorrow. It’s about a 60% chance of rain for Satruday with the best chances coming Saturday night and Sunday morning. The return of fall weather comes Monday as the highs stay in the 60’s. Below are the forecasted highs for our area.

Wonderful Wednesday Weather

Wednesday, September 20th, 2006

This is the type of weather a guy can get behind. Chilly this morning (40s and lower 50s) with sunshine, dry dewpoints and high temperatures in the 60s to near 70. The visible satellite image shows a couple clouds in the far northeast corner of Middle Tennessee, but not much more than that. Dewpoints are down in the 30s and 40s, setting the stage for a cool night and early morning. Lows should dip down to the 40s for just about all locations. Temperatures climb from Thursday through Saturday as a brisk southerly wind develops (especially Friday & Saturday) ahead of our next cold front. The approaching front brings isolated t’showers by Friday and Saturday, with the best chance Saturday night into Sunday morning as the front crosses. We’ll watch the timing of that front closely over the next few days. Behind the front, another shot of cool air expected for early next work week.

Visit to Ft. Campbell

Wednesday, September 20th, 2006

Had the opportunity to head to Ft. Campbell Tuesday morning to visit with many of the kids at Marshall Elementary School. Many thanks to Michelle Bague for setting up the talk and gracefully postponing the date a few times due to my weather duties in Nashville. She also gave me a delicious bag of Puerto Rican coffee that won’t last long around this television station. Additional thanks to Administrative Officer Rudy Stone for giving me a tour of the impressive 105,000 acre facility. Pictures at the school after the jump.

We started this morning with lows in the upper 40’s. Early sunshine and this dry air will warm quickly to around 70 by afternoon. A few clouds around but another night today in the upper 40’s. Tomorrow the winds start to pick up from the south; the high will reach into the upper 70’s with more clouds. By Friday rain in the forecast as a cold front slow moves towards us over the weekend; it probably won’t get here until Sunday. That means rain in the forecast Friday, Saturday and Sunday. On the other side of this cold front even colder temperatures; we might get overnight lows in the northwest down into the upper 30’s by the start of next work week. Below are today’s forecasted highs.
