Changeable Skies This Week…

Monday, September 26th, 2005

Arlene, Dennis, Katrina and Rita: all named storms that gave us some rain this summer. Where would we have been without that rainfall this summer? In a pretty big drought!

What’s left of Rita continues to push way from Middle Tennessee. Some lingering showers will occur for the morning commute east of Nashville. Around lunchtime we may grab a few sunny breaks before a couple more t-showers develop late this afternoon. No strong weather is expected this afternoon.

After a few sunny days Tuesday and Wednesday, a stronger cool front will cross the midstate late Wednesday night. Albeit brief, it will bring us our first true taste of Autumn this season. The 7 day forecast is above.

Are we done with the 90 degree heat??? Probably…average highs this time of year are around 80, so it would be quite a stretch to get there again.

Leftovers From Rita Slowly Pull Away…

Monday, September 26th, 2005

A little “excitement” and a few anxious moments yesterday as a few a couple of storms showed some possible rotation. It is fairly common to have some weak, short-lived tornadoes on the eastern side of a tropical system just due to the general spin in the atmosphere at the time. Had some reports of damage in Lawrence and Maury Counties last evening.

Looks like a few more showers are going to be possible today (Monday.) I’ll have more on that a bit later this AM. Headed now to my 2 am “happy-place” the computer maps…see you on the other side!

Looks like a pleasant shot of Autumn coming our way later this week…how cool will it be is the question though(?)

Windy enough for you?

Sunday, September 25th, 2005

Despite the tornado watch, we haven’t had a tornado warning this afternoon in Middle Tennessee. There have been several warnings just across the Alabama border, so we’ll have to stay on our toes this evening. Walking outside this afternoon in Nashville reminded me of living on the wind-swept plains of the Upper Midwest (Sioux Falls is lovely this time of year, by the way.) Gusty winds are causing a few problems across the mid-state: in the comments section of an earlier entry, Brad Foster mentioned some damage to his home in Cookeville. Here’s a link to current Middle Tennessee weather observations. SE22G29 would be a southeast wind sustained at 22 mph and gusting to 29 mph.

With Rita spinning off to our west, winds in nearly all levels of the atmosphere are blowing from the same direction (the south). Here’s a map of the Mid-South at the 850 millibar level from 7am CDT this morning. That’s about 5,000 feet up in the sky. On a clear and breezy day, a good forecast rule is to use the 850 mb wind speed as a rough estimate of your top wind gusts that afternoon. It’s a good thing that’s not the case today: the blue triangle over Nashville translates to 50 knots (58 mph)! Because of the cloud cover, we’re not mixing down as much of the atmosphere’s wind energy. Gusts across the area are still reaching around 40 mph at times.

Watch vs. warning: do you know the difference?

Sunday, September 25th, 2005

You hear us talk about watches and warnings when the weather turns active, but do you know the difference between the two?

The Storm Prediction Center issues a tornado watch or severe thunderstorm watch when conditions are favorable for severe weather to develop over the course of several hours. Watches cover large areas (like all of Middle Tennessee) but are not a guarantee that severe storms will roll through your backyard.

When a tornado or severe thunderstorm is spotted on Doppler radar, the local National Weather Service office will issue a tornado warning or severe thunderstorm warning for a specific county. A warning means that severe weather is expected to occur shortly in the warned area.

To sum it up, a watch means you should be on guard for the possibility of severe weather. A warning is more important and indicates that severe weather is happening in your county. Warnings mean that you should take action to protect your family and your property now!

Tornado watch until 7pm CDT for Middle Tennessee

Sunday, September 25th, 2005

The Storm Prediction Center just issued a tornado watch for Middle Tennessee until 7pm CDT. The strong line of thunderstorms on Rita’s eastern flank that stretched from West Tennessee to Mississippi this morning will move into western parts of the mid-state during the early afternoon. Read the rest of the tornado watch at the SPC’s website.

To view a map of the tornado watch, click here.

Tornadoes associated with tropical systems like Rita are usually cloaked with rain and difficult to spot. If a tornado warning is issued for your county, don’t take any chances! The safest place to be during severe weather is in the center of the lowest level of your home away from windows. Mobile homes are not safe places to ride out severe weather.
