Looks like another Rossby Wave Break Event is likely by next weekend though exact positions of cut off lows and high pressure TBD

As the cut off low across West America via this Rossby Wave Break Event transitions into Northern States the next significant flash flood threat will evolve as the cyclonic system enters Iowa.

Newest data suggesting highest precip rates at the border of Nebraska, South Dakota and Iowa, with the flash flood threat moving into Minnesota and Wisconsin then progressing Northeastwards.

Severe weather associated with this event too.

The very active weather will continue to evolve throughout Europe with multiple significant weather events.

Snow

Ongoing significant snowfalls continuing across the Alps.

Another potentially significant snow event could swing back into Albania, Kosovo, current trends really keen into Montenegro, Bosnia and Herzegovina, perhaps North Macedonia and parts of West and Southwestern Serbia, this event currently modelled for Sunday and Monday.

There is also an ongoing snow event from the Belarusian border crossing Russia with significant accumulations.

And another area of snow intensifying as it moves across Norway again further significant accumulations likely.

Significant flash flood threat.

A significant rainfall event will develop through Saturday into Sunday across Greece and moving into Turkey, after crossing the Black Sea this could continue bringing a significant flash flood risk into Moldova and Ukraine and possibly Belarus.

Interesting small cyclonic system in the Atlantic which has been given 10% to obtain tropical characteristics over the next few days

 

After decaying this systems moisture will become part of a Rossby Wave Break Event during this weekend into early next week.

Looks like this system spawned from a CCKW from South America 

 

With influence of CCKW activities and the MJO itself mentioned in the above post, there will be a significant - possibly major snow event across the Himalayas as a mix of troughing and cut off lows converge by April 28th. Overall a significantly snowy setup for Russia and Asia with accompanying cold > significantly cold temperature anomalies which will extend into parts of the Middle East.

This once again coinciding with a move into a negative phase of the Arctic Oscillation.

This CCKW and MJO activity will also keep significant rainfall and significant flash flood risk events ongoing across East and Southeast China, Taiwan and Japan through at least May week 1.
