Warm, spring-like weather has been conspicuously absent for much of May.   However,  a late spring and more summer-like pattern is evolving in the Atlantic, where a Bermuda high pattern is expected to establish itself over the next few days into the weekend.

Warmer temperatures and higher humidity is expected for Memorial Day Weekend.  It is  unknown whether the Bermuda high will be strong enough to fend off showers and thunderstorms that are depicted to develop to our west, south and north.

Right now, the GFS model is keeping us dry through the weekend, from Saturday through Monday.   But the model trend has been for a weakening of the high pressure dome which may allow showers to sneak in if the trend continues.

So it looks to be a nice weekend here in Philly and at the NJ shore, but it wouldn’t take much for that forecast to go bust.
