Possible Tornado/117 mph Wind Gust in Amory MS Earlier?

| 10:07 am May 25, 2015

LATE REPORT
From the NWS Memphis: Smithville [Monroe Co, MS] public reports TORNADO at 09:03 AM CDT — smithville marina reports boats toppled over and buildings demolished. definite path of destruction.

ORIGINAL POST
That impressive little mesoscale convective vortex over Northeast Mississippi that prompted the tornado warning for the Amory and SMithville areas weakened as it moved into more stable air over Northwest Alabama and is no longer considered severe by the definition. It is still capable of strong gusty winds and is producing a fair amount of lightning and heavy rain.

It extends along an arc from Tishomingo MS to Vina in Franklin County, Alabama to near Hamilton in Marion County. It is moving northeast at about 35 mph. The strongest winds are now approaching Hamilton. It will impact the rest of Franklin and Marion Counties over the next hour.

Reports from Amory say that there is a considerable amount of damage in the downtown area from straight line winds or possibly a small tonado.

Here is a Twitter image of what may have well been a tornado in Amory. There was certainly a strong velocity couplet in the area at the time.

A home weather station in Amory reported a wind gust to 117 mph. While not official, that is still impressive.

To the south, more strong storms are north of Columbus MS and will affect northern Lamar and Marion Counties.

Further south, a severe thunderstorm warning is in effect for a small but strong cell in southwestern Noxubee County MS southwest of Macon. The warning includes Macon. This is going to affect Columbus in 90 minutes or so. It is part of an area of storms southwest of Columbus that will run into some higher instabilities as it translates eastward over the next couple of hours and pushes into West Alabama.

Could a Watch Be In Our Future?

| 9:19 am May 25, 2015

A potent little mesoscale convective vortex is rotating into Northwest Alabama early on this Memorial Day.

There is very little instability ahead of the system, but it is ingesting unstable air from the south on a strong low level wind. So it is uncertain how long it will be able to maintain itself, but it has impressive rotation and is moving into an area with southeasterly surface winds, so there is a small tornado threat

The SPC has just put out a statement that a tornado watch is possible if the feature holds together.

The SPC does not have Alabama outlooked for severe weather today since the threat for severe weather is not significant or widespread enough to warrant a risk forecast. But a small feature like this can sometimes trigger localized severe weather and we will be monitoring it.

There is a moderate risk today over southern Oklahoma and northern Texas into extreme southwestern Arkansas where the SPC feels that a very strong upper level disturbance approaching from the southwest.

Heads Up Lamar/Marion Counties

| 8:45 am May 25, 2015

8:45 a.m. Monday

As expected, the first line of storms weakened as it crossed into Alabama overnight, but stronger storms are over Northeast Mississippi at this hour, poised to enter West Alabama within the hour.

A severe thunderstorm warning is in effect for the Aberdeen area in NE Mississippi. This is for a pronounced bow echo Okolona to Aberdeen to West Point. Bow echoes are a part of a line of thunderstorms that “bows” out in front of the rest of the line. Along the arc of the bow, very strong winds are possible.

This bow will target Lamar and Marion Counties within the hour, pushing near Bexar, Detroit, Sulligent and Hamilton.

At the head of the bow, tornadoes can occur, and the NWS Memphis has also issued a tornado warning for the area around Amory and Smithville. The possible tornado is near Egypt, MS. On its current track it will impact Smithville MS and move toward Bexar in Marion County between 9:30-9:45 a.m.

There has been a definite velocity couplet on the storm, indicating rotation and possible tornado.

Is the Severe Weather Over for Central Alabama? Yes!

| 6:35 pm April 25, 2015

2015-04-25_18-52-08

Yes!

The severe thunderstorm watch for East Central Alabama has been canceled as the last storms have moved into Georgia and no addiitonal storms are expected overnight.

We had one shot at severe weather this afternoon and evening across Central Alabama and it is done.

The ingredients that were in place over the area are diminishing now. The speed shear is diminishing as the upper level wind max departs to the north. Instabilities are slowly coming down as clouds cover the area. The convection near the Gulf Coast has effectively cut off additional moisture inflow into the area and drier air is moving in.

There should not be any more convection initiating tonight. There could be a few light showers as the cold front approaches from the north during the pre-dawn hours, but there won’t be any thunder.

A passing disturbance and conditionally unstable air caused by cold air aloft tomorrow could trigger a few light afternoon showers as well, but they will be a nuisance at worst, not heavy and not lasting very long at all.

@auburnwde reported destruction of a barn in northern Coosa County caused by strong winds in the severe thunderstorm at 5:18 pm, four miles west of Stewartville on County Road 35. The damage is impressive and could have been caused by a tornado or straight line winds, hard to tell until the Weather Service surveys the damage. There were definitely strong winds, over 65 mph near the surface, shown on doplar radar.
