Today has been moderately depressing in terms of technology. Normally, I do a weather report on the train in the morning, but my tablet died (and isn’t going to be replaced anytime soon), so I did no such thing.
Weather-wise, there is a massive mid-latitude cyclone and strong cold front that is driving all sorts of severe weather in the Great Plains and winter weather in the Rockies and High Plains. There were quite a few severe weather reports, including 48 tornado reports spread over Texas, Oklahoma and Kansas.
There are still active Tornado Watches over most of the southern Great Plains.
There are still severe thunderstorms occurring over central Oklahoma as well. The radar image from GRLevel3 shows several stronger storms in this line. Currently, there is not much rotation, according to the storm relative Doppler image.
These severe storms formed along the strong cold front that extended from the mid-latitude cyclone. This strong cold front provided a ton of forcing, and now the cells have merged into one large line. The enhanced infrared imagery shows the extent of the thick, cool, high-topped clouds that form this line.
The mid-latitude cyclone itself has a central low pressure of 992 mb, and there is a sharp pressure gradient on all sides of this system.
Behind the cold front is the bitter arctic air mass that has traveled south. Here in New Mexico, the temperature is quite chilly and the wind is howling loudly outside.
The 300 mb NAM shows the deep trough.
I will be watching the weather this evening and tomorrow.
