总算温气版有人提到这个系统了,巅峰已过,WPC分析气压968mb,美国多地阵风、降雪量、气压打破当地极值,并且似乎搞出了龙卷风。

Powerful Storm System Continues to Produce Significant Impacts for Large Swaths of the U.S.

An intense storm across the central Plains will continue to bring blizzard conditions to parts of the northern Plains and Rockies through Thursday, where travel remains difficult. Heavy rain, snow melt, and ice jams on rivers have produced widespread flooding across the Upper Midwest. Severe storms with damaging winds, hail, and tornadoes are possible from the Great Lakes to the South.
Short Range Forecast Discussion
NWS Weather Prediction Center College Park MD
405 AM EDT Thu Mar 14 2019

Valid 12Z Thu Mar 14 2019 - 12Z Sat Mar 16 2019

...The strong winter storm to continue to affect portions of the Central
to Northern Plains today with Blizzard conditions continuing...

...Winds will be diminishing across the Southern and Central Plains as the
storm pulls away from these regions...

...Thunderstorms will bring heavy rains, isolated flooding and a severe
weather threat Thursday from the Lower Mississippi Valley into the
Tennessee and Ohio Valleys...

...Much above average temperatures likely east of the Mississippi River
Thursday, across the eastern U.S. Friday...

...Much colder temperatures will spreading into the Mississippi, Tennessee
and Ohio Valleys Friday and the east coast on Saturday...


The intense storm across the mid section of the nation that has been
responsible for heavy snows, blizzard conditions and widespread wind gusts
over hurricane force will be pressing northeastward through the Upper
Mississippi Valley into the Upper Great Lakes on Thursday.  While the
storm has reached its lowest pressure and will gradually weaken over the
next few days, strong winds will continue on the west side of the storm
across portions of the Central and Northern Plains.  Blizzard conditions
are expected to continue into the first half of Thursday over northeast
Colorado and for most of the day from eastern Wyoming, across most of
Nebraska, South Dakota, eastern North Dakota into northwest Minnesota.
Travel will remain difficult and life threatening across these areas, with
improving conditions Thursday night into Friday as the storm pushes
farther off to the northeast.

As the strong storm pushes northeastward today into the Upper Mississippi
Valley, winds will be lessening across the Central to Southern Plains that
experienced widespread wind gust over hurricane force during the past 24
hours.  High wind warnings remain in effect into Thursday morning for
southeast Colorado and western Kansas, but overall a much smaller area of
strong wind gusts expected Thursday as the storm moves away from this
region.

The associated cold front with this strong storm will continue to be a
focus for thunderstorm activity from the Lower Mississippi Valley into the
Tennessee and Ohio Valleys. Heavy rains, isolated flooding and severe
weather are possible with these thunderstorms across these regions.

A taste of spring temperatures likely ahead of the above mentioned cold
front front on Thursday for all areas to the east of the Mississippi River
and for areas east of the Appalachians on Friday.  Much colder
temperatures expected in the wake of this front today from the Great
Basin, Rockies into the Plains.  These colder temperatures will be
spreading eastward on Friday into the Mississippi, Ohio and Tennessee
Valleys and into much of the eastern U.S. on Saturday.

风场扫描不扫陆地上的 只能拿这个来代替一下了
明显西侧由于靠近冷高压而风力较强
