Bellevue Lightning; Today's Lightning Storm Risk

This image was taken last night at around 9:55 in the Bellevue area by Clarence Bennett who caught this AMAZING lightning strike as storms where moving through the region! We could see more of this activity later on today as well. In the form of MANY Special Weather Statments, Severe T'storm Warnings and maybe wind damage.
Here's the SPC's take on the severe risk areas today and we are right, again, in the "See Text" region. My thinking is that the areas who will most likely see the stormy action, will be the areas south of I-40. We won't see much in the way of severe weather up here, due to the fact of this morning rain stabilizing the atmosphere and it won't have time to recover for this afternoon's event. Here's today's forecasted high's, as well as the rain chances for this afternoon.

Nashville: mid to upper 80's!; 60% chance this afternoon
Clarksville: mid 80's; 50% chance
Cookeville: low to mid 80's; 60% chance
Columbia: upper 80's; 60% chance
Manchester: upper 80's; 70% chance

Albuquerque, NM Storm Photos

I have these photos sent to me from Leah Robertson out of Albuquerque, NM. This picture of a mini-rainshaft, was taken over SE Albuquerque. I'd love to go out there and taken photos and videos...you could literally see for miles and miles!
This picture is also from Leah Robertson and this was taken on July 25th from Albuquerque, but the storm was around Belen, NM. You can clearly see a weak anvil sticking out the side of the cell. Thanks Leah for these wonderful photos!

Tornado Vortex Signature (Weatherunderground Radar)

I came by this while looking at the weatherundergroud radar, and as you can tell, the radar was picking up a Tornado Vortex signature at around 10:22 for Western Wilson County (Mt. Juliet area). I don't know why it picked it up, but it sure did. I thought I might need to share that with you guys.

MSD (TN and SE KY)

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

Because of the isolated nature of the severe potential...a watch is unlikely. But the severe threat could last a few more hours...til the sun goes down.

Storm Updates

Here's the weatherunderground radar image as of 3:05. There's a Severe T'storm Warning in effect for E Central Davidson County and NE Wilson County for damaging wind gust reaching past 60 mph. The Emergency Management has reported down trees and power lines from this same storm. More storms could fire up later on during the afternoon til the sun goes down and takes all the fueling power away with it. Tomorrow looks to be about the same as today is too.

Glen Falls, NY Storm Pictures; Low Severe Risk Today

These pictures where both taken by Monica Dobbs in Glen Falls, NY, on July 26th. She writes, " There was a series of storms that moved through, and produced some good lightning in my region. They also produced, in nearby regions, hail and high winds. We were lucky not to get any of that." Now this photo is pretty amazing. As you can see, there's a cloud or fog mist right in between her house and the neighbors house. But the cool thing is, is that it looks to be forming. You can't really tell by a picture, but she believes from capturing it on camera and watching it, it was forming right above her. Cool! Thanks Monica for sharing these photos with us here in TN. I have more photos that I will continue to share with you later on this week.

I chose her photos, due to our risk of seeing some lightning later on this afternoon. While the risk is low, here's the SPC's take on what may or may not happen.

...TN/OH VALLEYS INTO THE MID-ATLANTIC REGION... SEVERAL SMALL-SCALE FEATURES MOVING EWD THROUGH BROAD/WEAKLY-CYCLONIC FLOW ALOFT OVER THE NERN QUARTER OF THE U.S. WILL CONTRIBUTE TO THE DEVELOPMENT OF SHOWERS AND THUNDERSTORMS AS AIR MASS DESTABILIZES DIURNALLY. WHILE STRONGEST FLOW WILL REMAIN ACROSS THE GREAT LAKES WHERE SOMEWHAT WEAKER INSTABILITY IS EXPECTED...MODERATE FLOW FIELD WILL EXTEND AS FAR S AS THE TN VALLEY/MID-ATLANTIC REGION. THUS -- A FEW STRONGER CELLS WHICH DEVELOP ACROSS THIS REGION WILL BE CAPABLE OF PRODUCING DAMAGING WINDS/MARGINAL HAIL.

My forecast calls for not alot of severe weather, but for a mostly good late July/Early August rain gift. We don't get these chances too often, so any wet weather we can get...I won't complain. Here's today's forecasted high's, along with the afternoon and overnight rain chances.

Nashville: low to mid 90's; 30% chance...^ to 60% tonight
Clarksville: low 90's; 30% chance...^ to 60% tonight
Cookeville: upper 80's to low 90's; 40% chance...^ 60% tonight
Columbia: low to mid 90's; 30% chance...^ 60% tonight
Manchester: low 90's; 40% chance...^ 70% tonight

Muggy Night; Rain Chances

It will be another muggy night here in the Mid-State. Temperatures will stay in the low-to-mid 80's. Rain Chances for tonight are VERY low. The areas that could be seeing rain are in the southwestern counties, where rain is already present.

Tomorrow, we are running a VERY LOW chance of seing some strong to severe thunderstorms. The main threats with these storms will be damaging winds.

If the severe weather doesn't happen, the rain will, maybe. Rain chances look best on Thursday as a weak frontal boundary tries to push in to the mid-state. Chances for rain on Thursday look to be about 50%.

Update on Site: The RADAR, is going VERY slow. I'm trying to load one, but the computer just won't do it, yet. I'm working on it, so bear with me. The Graphics are coming along, i'll have them by Friday.

Have a Great Night, and Safe Day.

Pop-up Day #2

I took the weatherunderground image of the storms that have pop-uped in south and eastern TN, and added the blue outlines to the counties that the NWS in Nashville has put out a Short Term forecast for. Here's the List of the 17 counties and what the forecast says.

TNZ009>011-029>034-063>066-077>080-291830-MACON-CLAY-PICKETT-TROUSDALE-SMITH-JACKSON-PUTNAM-OVERTON-FENTRESS-CANNON-DEKALB-WHITE-CUMBERLAND-COFFEE-WARREN-GRUNDY-VAN BUREN-INCLUDING THE CITIES OF...LAFAYETTE...CELINA...BYRDSTOWN...HARTSVILLE...CARTHAGE...GAINESBORO...COOKEVILLE...LIVINGSTON...JAMESTOWN...ALLARDT...WOODBURY...SMITHVILLE...SPARTA...CROSSVILLE...FAIRFIELD GLADE...TULLAHOMA...MANCHESTER...MCMINNVILLE...TRACY CITY...ALTAMONT...COALMONT...SPENCER1157 AM CDT TUE JUL 29 2008.NOW...WIDELY SCATTERED RAIN SHOWERS AND THUNDERSTORMS CONTINUE TO FORM OVER PORTIONS OF THE EAST HALF OF MIDDLE TENNESSEE AND OVER THE CUMBERLAND PLATEAU.THESE SHOWERS ARE MOVING TO THE SOUTHEAST AT 15 MPH. RAINFALL AMOUNTS IN THE HEAVIER STORMS WILL BE LOCALLY HEAVY AT TIMES.MOTORISTS SHOULD BE CAREFUL OF PONDING OF WATER IN LOW LYING AREAS OF ROADWAYS.

Foggy Start For Some; Balmy Day Awaits

After yesterday's pop-up feast. Today looks about the same, but with less coverage and intensity in the pop-up storms. The western half of Middle TN stands the best chance at witnessing the t'storm activity later on this afternoon, but I can't discount the chance at a pop-up shower/t'shower for the Highland Rim, Cumberland Plateau, or Southern TN areas. With the less morning cloud coverage, it opens the window for more of a mid 90 degree day for Middle Tennesseans. With the temperatures getting in the mid 90's, the Heat Indexes will be getting well up into the upper 90's around 100ยบ's. Here's today's forecasted highs in addition to the storm chances.

Nashville: mid 90's; 20% chance
Clarksville: low to mid 90's; 30% chance
Cookeville: low 90's; 10% chance
Columbia: mid 90's; 30% chance
Manchester: low to mid 90's; 20% chance

Mesoscale Discussion (Eastern KY and TN included)

A watch is unlikely, but the chance for some more afternoon pop-up storms is possible as the system continues to move eastward out of the area.
