Tornadoes Strike New Orleans area

A massive feature moving through the center of the country, the second this month, is bringing blizzard conditions to the Northern Plains, but it will be remembered for quite some time for the path of destruction it is weaving across the southern US.

The storms started yesterday, with tornadoes striking the Dallas-Fort Worth metro, including causing 5 injuries at a Sam’s Club and mall in Grapevine.

There were even more tragic consequences south of Shreveport, where tornadoes claimed the lives of two near Keachi as the tornado swept through some mobile homes. There was another prominent cluster of tornado reports between Monroe, Louisiana and Vicksburg, Mississippi. Fortunately, only one injury was reported there.

The storm carried on today, and started early. Storms fired early, and slightly to the southeast of Tuesday’s storm activity. Storms were seen in Mississippi through much of the day, before tornadoes struck throughout the city of New Orleans. Fortunately, none appear to have been major tornadoes, but they struck impoverished, poorly soiled and urban areas, so damage has been great.

Reports specifically have come out of Gretna and the Algiers and Arabi neighborhoods of New Orleans. Arabi was clipped by a tornado earlier this year, doubling down on bad luck for New Orleans. A tornado watch and the threat thereof continue this evening in the Florida Panhandle and south Georgia. Tornadoes were also noted northeast of Apalachicola today.

An impressive jet trough digging into the middle of the country is urging the helicity necessary to produce these tornadoes, and sustain them over the course of several days. In addition, the depth of this trough is allowing the cold air necessary to clash with the marine air as far south as New Orleans. The base of the trough is going to continue to shift to the east, taking with it the threat of continued severe weather, aside from some early straight line winds in north Florida tomorrow.

Cold and getting colder

Everyone knows that it’s getting colder when December rolls around, so to start the month with a forecast that feature descending temperatures is insult to injury. It’s made worse by forecasts being warmer than what ultimately verified, as was the case in Tulsa at the beginning of the month. A cold front that was unencumbered with moisture brought brisk winds and chilly temperatures progressively through our forecast period. It started colder than expected and stayed that way. Accuweather had the best line on the chilly weather, not that it was a great forecast.

Goldsboro, North Carolina

Back to the Tar Heel State for a forecast in Goldsboro. A lot of ‘boros in North Carolina.

At 855PM, ET, Goldsboro was reporting mostly cloudy skies with a temperature of 42 degrees. A massive, deep area of low pressure is on it’s way north towards Nova Scotia, and is dangling a cold front that is primarily inactive onshore, save for a thick shield of clouds well to the north of the boundary, and more scattered activity in the Carolinas before the boundary is visible in south Georgia. If the clouds don’t fill in fast enough, Goldsboro may approach freezing, but tomorrow morning will be cloudy.
While the low headed to Nova Scotia is stout, it is going to be quickly forgotten in the CONUS. A strong trough moving out of the Rockies is going to bring a warm front into the region. The feature is going to be a headline maker in the middle of the country with winter weather in the Northern Plains, and a perturbation in the southern part of the boundary is already bringing severe weather to the Southern Plains tonight. The severe storms will continue into the lower Mississippi Valley tomorrow, with continued storm activity along the Gulf Coast Wednesday. The severe storms and most unstable air will stay south of the Carolinas, but in the evening on Wednesday, rain will arrive in Goldsboro, leading to a soggy end of the week.

Here is a look at the satellite, with the Carolinas in the happy middle between sheaths of overcast.

A splashy send off to November

Rain was on the way when we looked at Decatur at the end of the last month, and arrive it did. An inch and a third fell the morning of the 30th, sending temperatures down to below freezing by the end of the day. It was dry, fortunately, to start December, though it was cooler than it had been by quite a bit just two days before. Weatherbug nabbed this transitional forecast victory.

Durham, North Carolina

We are 4 days into December, and it’s already snowed twice at the Victoria-Weather headquarters. Let’s see how it is going in North Carolina.

At 1130, ET, Durham was reporting a temperature of 39 degrees with clear skies. An elongated ridge ran along the coast, with the southwestern end nosing into the Carolinas, keeping Durham dry this evening. The tenuous existence of the ridge will make the Carolinas susceptible to wet weather over the next couple of days, despite the clear skies at present.
There is a low level perturbation that is moving east out of northern Alabama tonight, and will attempt to wrap under the southern Appalachians and into the Carolina Plains with limited success. A more notable feature moving through Canada will dangle a cold front that eventually catches up to the perturbation lurking in the southeast. This boundary will more effectively tap into the moisture drawn in tomorrow morning, leading to some clouds and light rain throughout the day on Tuesday. Don’t expect the front to ever reach Durham, however, so a dramatic cool down will be averted.
Tomorrow – Partly cloudy, High 55, Low 32

Satellite tonight shows whispers of clouds over Durham, but a pleasant day is promised ahead, unless you ask Weatherbug.

Tulsa, Oklahoma

Today’s forecast takes us to another part of the country that is known for strong spring time weather, after Decatur earlier this week. Will Tulsa see cool and calm like Decatur did, or will we see something different?

At 953AM, Tulsa was reporting a brisk 42 degrees with mostly cloudy skies and wind gusting over 20mph. The jet was quite strong, which is not unusual for the time of year, and ridging through the center of the country. High pressure centered over the Ohio Valley was generating the brisk wind on it’s back side, with return flow bringing some of the cloud and chances for rain in the southern Plains.
Over the Rockies, this same strong jet is producing a trough, which hasn’t fully materialized into a surface low yet, thanks to the local terrain. Expect a deep area of low pressure to emerge over South Dakota tomorrow morning, enhancing the windy conditions over Tulsa. Flow will be from the southwest, with high pressure still nosing into the northern Gulf, and this will staunch moisture flow into Oklahoma. The associated cold front will arrive late Friday with similarly gusty winds, and a significant Saturday cool down.
Tomorrow – Passing clouds, breezy, High 67, Low 48
Saturday – Partly cloudy, colder but less windy, High 49, Low 32

TWC: Tomorrow – Overcast. High 65, Low 46
Saturday – Partly cloudy skies. High 49, Low 33

AW: Tomorrow – Mostly cloudy, windy and warmer High 64, Low 47
Saturday – Mostly cloudy and cooler High 48, Low 30

NWS: Tomorrow – Mostly cloudy, High 66, Low 46
Saturday – Mostly sunny, High 51, Low 35

WB: Tomorrow – Mostly cloudy in the morning, then becoming partly sunny. Breezy, High 65, Low 47
Saturday – Mostly sunny, High 50, Low 37

WN: Tomorrow – Partly cloudy, High 65, Low 47
Saturday – Partly cloudy, High 46, Low 36

FIO: Tomorrow – Windy in the morning and afternoon. High 64, Low 44
Saturday – Windy overnight. High 53, Low 33

The high on Saturday will probably come at midnight. The WeatherNation hourly forecast doesn’t extend that far out, but they shouldn’t be too far off. Check out the satellite, showing clouds wrapping around high pressure in Texas and Oklahoma.

Decatur, Alabama

Tonight’s forecast takes us to an area under threat for severe weather. The strongest storms are in Mississippi, but northern Alabama remains in a slight risk for severe weather.

At 853PM, CT, Decatur was reporting cloudy skies and a temperature of 63 degrees. Low clouds and cool temperatures across northern Alabama suggest that the threat for severe weather is likely over, however, there is plenty of rain and thunder across central Tennessee that looms as a possibility overnight. Flash flooding is always a possibility, but the strong winds and tornadoes will remain to the southwest.
The parent area of low pressure associated with tonight’s storms is moving north of the Great Lakes, while a secondary vorticity maximum was centered over western Kentucky, providing the atmospheric spin, and emphasis on moisture importation to the region tonight. As a unit, this feature is progressing swiftly to the east, and the threat of rain should be clear of Decatur by sunrise. The high pressure that builds behind this system will be stout but transient. The next two days will be cool and clear, a recovery after a rainy and stormy night.
Tomorrow – Rain ending early, then becoming sunny, High 58, Low 30
Thursday – Sunny, High 52, Low 27

TWC: Tomorrow – Some clouds in the morning will give way to mainly sunny skies for the afternoon (early rain). High 62, Low 33
Thursday – Some clouds in the morning will give way to mainly sunny skies for the afternoon. High 52, Low 29

AW: Tomorrow – Cooler with clouds giving way to sun; breezy in the afternoon (Early Rain) High 60, Low 34
Thursday – Sunshine, High 52, Low 29

NWS: Tomorrow – Partly sunny, then gradually becoming sunny, (Rain early) High 67, Low 36
Thursday – Mostly sunny, High 51, Low 31

WB: Tomorrow – Much cooler, mostly sunny (Early rain), High 62, Low 33
Thursday – Partly cloudy, High 50, Low 30

WN: Tomorrow – Partly cloudy with showers and scattered storms, High 64, Low 36
Thursday – Partly cloudy, High 51, Low 32

FIO: Tomorrow – Heavy rain overnight and in the morning. High 63, Low 34
Thursday – Partly cloudy throughout the day. High 51, Low 29

Temperatures tomorrow will be falling through the day as high pressure settles in. Some rain looms to the northwest, but mercifully, none of it will bring terrible storms.

November forecaster of the Month

We are a couple of days from the end of the month, but with a handful of forecasts coming up, and a looming threat of severe weather coming tomorrow, I thought we might as well grab some time now to reward the top forecaster from the past month. The top spot this month belonged to the fine folks at the National Weather Service, who took the prize, thanks to good old fashioned consistency.

Terrific weather by the Lake

If any one traveled around the western Great Lakes for Thanksgiving, you will be well aware that the weather was very good. In Racine, it was generally sunny, though with a few spots of clouds here and there for the two days before Thanksgiving, and it was warm. In fact, temperatures exceeded expectations on Wednesday, climbing all the way up to 55. Now that is something to be thankful for. Victoria-Weather navigated the low temperatures in Racine the best, which was the difference in our Turkey Day triumph.
