Severe WX March 21-23 2022

Ominous MCD...

NWSChat - NOAA's National Weather Service

MESOSCALE DISCUSSION 0310

NWS STORM PREDICTION CENTER NORMAN OK

1219 PM CDT TUE MAR 22 2022
AREAS AFFECTED...PARTS OF SOUTHERN INTO CENTRAL MISSISSIPPI
CONCERNING...TORNADO WATCH 61...

VALID 221719Z - 221915Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 61 CONTINUES.

SUMMARY...ONE OR TWO SUSTAINED, LONG TRACK SUPERCELLS WITH THE
POTENTIAL TO PRODUCE STRONG TORNADOES MAY GRADUALLY BEGIN TO EMERGE
ACROSS SOUTH CENTRAL THROUGH EAST CENTRAL MISSISSIPPI THROUGH
18-21Z, IN ADVANCE OF A SQUALL LINE PROGRESSING EAST OF THE LOWER
MISSISSIPPI VALLEY.

DISCUSSION...STRONGEST BOUNDARY-LAYER DESTABILIZATION THE PAST FEW
HOURS HAS BEEN FOCUSED ALONG A CORRIDOR OF STRONGER LOW-LEVEL WARM
ADVECTION, PRECEDING THE INCREASINGLY EXTENSIVE CLUSTER OF
THUNDERSTORMS SLOWLY SPREADING INTO/ACROSS THE LOWER MISSISSIPPI
VALLEY. THIS IS CONTRIBUTING TO DEEPENING CONVECTIVE DEVELOPMENT
ACROSS MUCH OF SOUTHERN THROUGH CENTRAL MISSISSIPPI, WHICH LIKELY
WILL CONTINUE THROUGH THE 18-21Z TIME FRAME. THOUGH THE NUMBER OF
CELLS WILL PROBABLY DECREASE, STRONGER MORE WIDELY SCATTERED
DISCRETE STORMS PROBABLY WILL BEGIN TO EMERGE IN AN ENVIRONMENT WITH
CAPE INCREASING TO 1500+ J/KG. THE CONTINUED INLAND AND NORTHWARD
PROPAGATION OF A STRONG SOUTHERLY 850 MB SPEED MAXIMUM HAS AND WILL
CONTINUE TO CONTRIBUTE TO VERY LARGE, CLOCKWISE CURVED LOW-LEVEL
HODOGRAPHS CONDUCIVE TO THE EVOLUTION OF SUSTAINED, STRONG
MESOCYCLONES WITH THE POTENTIAL TO PRODUCE SIGNIFICANT TORNADOES.
GIVEN THE STRENGTH OF THE SOUTH-SOUTHWESTERLY DEEP-LAYER MEAN FLOW,
THESE WILL BE FAST MOVING (IN EXCESS OF 50 KT) WITH THE POTENTIAL
FOR ONE OR TWO TO BECOME FAIRLY LONG TRACK.

If any of these go fully surface based, there's where our big trouble will be, otherwise mostly very prolific QLCS fest, the worst kind to warn and prepare for

From JAN... Weather spotters confirmed tornado in Yazoo County:

"At 1223 PM CDT, tornado producing storms were located along a line
extending from 8 miles southeast of Midnight to near Yazoo City to 7
miles east of Phoenix, moving northeast at 50 mph.

HAZARD...Damaging tornado.

SOURCE...Weather spotters confirmed tornado."
 
The moderate risk for excessive rainfall has been expanded to the south a good bit, which is obviously not good news on top of the severe threat.

I know this is off topic but figured I could get a quick answer. Do we still have the talkweather app for being mobile?

Not at this time. If you are using an iPhone you should get a prompt about installing a progressive web app that will put an Icon on your home screen. No alerting.... yet.

I'm not sure if it's the same for iOS, but on Android at least you can add a shortcut to TalkWeather to your home screen which opens it in a full screen browser window. It's close enough if you want to use TalkWeather on the go like I have to today.
