I never understood the unofficial start to summer for beaches in late May. Water is still very cold and temps can be very chilly too with any east wind.
To me the 4th of July weekend is the real start to summer.
Spring has been well above normal thus far. CC can cause cutoff lows due to the anomalous blocking. The rest of the country is torching. We're the island in the ocean of warmth.
What's crazy is we're still averaging well above normal months (March-May) but the warmth has been so extreme further west that our weather seems cool by comparison.
Ensembles show cutoff potential for early May, leaning towards 2nd week. Wouldn't be surprised to see a repeat of April, which was a mixed bag that's ending much warmer.
