Good morning! Our best chance for showers today is this afternoon with the upper trough moving in. Then a lingering shower tomorrow once we're on the backside and the system departs. Cool but dry Fri and Sat with showers becoming likely Sunday and Memorial Day.

I seriously hope that by sometime in June there's a pattern flip as nothing would be worse for summer than a cool and wet continued trend for outside activities lol.

I think it does continue into early June at least. How far into June remains to be seen. I think this is going to be a tough pattern to break with the PV weak and not in its normal spot over the North Pole. We had a big SSW event in late March and that has resulted in the cool May we have seen as well as the PV being located over N Europe instead of the North Pole., As a result, cool airmasses from Canada can easily invade the lower 48. Until the PV state and location changes, this is likely going to be the pattern. A blocking type pattern that we would see in winter to be honest.
