National Weather Service Assesses Super Tuesday Tornado Outbreak

National Weather Service Assessment

A nice "review of the review" of this can be found here.

This occurred on the same day as the Gassville, AR tornado and of the EF4 that produced a record path length in Arkansas. Our blog list for this day.

SNOWFALL FORECAST

There is a winter weather advisory in effect tomorrow across northern Arkansas.

An upper level disturbance will cause moisture to lift northward tomorrow while cold air pushes southward. Initially a bit of sleet may fall across northern Arkansas before changing over to all snow. Amounts will vary dramatically from Arkansas into southern Missouri. It appears a band of heavy snow will set up across northern Arkansas where greater than 2 inches will be possible. But this area has been shifted more to the south and is very narrow.

The models are in better agreement toward reducing overall snow totals today. Dry air and temperatures will be limiting factors.

Snow/Sleet Area

The Weather Lab is watching northern Arkansas and extreme southern Missouri for possible snow accumulation late tonight through early afternoon Thursday.

The latest arctic airmass is supplying enough cold air to this area to make the northern portion of a developing shield of rain capable of changing to sleet or snow.

The factors for determining snow totals are how much rain and/or sleet will be mixed with this precipitation and what will be the intensity.

Look for at least the possibility of a few inches of snow in the northern tier of counties in Arkanas including the cities of Harrison, Mtn. Home, Salem, Jasper and Marshall.

This is forecast to begin as rain and make the changeover sometime overnight tonight.

Severe Weather Tuesday 3/10/09

Look for a round of severe weather in the Ozarks on Tuesday.

Storms should fire in the early afternoon and the progress east and south over the area.

Instability looks weak and the winds are not real favorable for tornadoes but an isolated cell could develop one at some point late this afternoon or early this evening.

Tornado Drill for Missouri Today, Tuesday 3/10

The statewide tornado drill is scheduled for 1:30 today. Severe weather concerns appear to have lessened for that time of the day so as of now the drill will take place.

Sirens will go off and a test tornado warning will be transmitted, causing NOAA weather radio to alarm. Remember, this is only a test!

If your weather radio doesn't work or you need help programming it, you can always contact us at the Weather Lab. Or you can come out to JCPenney at the Battlefield Mall from 10 am to 4 pm, Saturday, March 14th.

Tornado Warning

A tornado warning has been issued for northern St. Clair until 1:15 am. This is a bowing segment thunderstorm type will is capable of producing damaging winds along its leading edge and perhaps a brief tornado.

This storm will continue to track into Benton Co. by 1:15 and may again showing a tightening rotation enough for another tornado warning.
