Summer is here, or it will be soon. It depends on how you define summer. Climatological summer (also known as meteorological summer) started on June 1. Astronomical summer starts with the summer solstice on June 21. No matter how you define summer, this week is going to start off miserably, by almost any definition.
The week starts off with low pressure moving off the Mid-Atlantic coastline early Monday, moving northeastward, passing south and east of New England during the day. This will bring us rain, possibly heavy at times, along with gusty winds and unseasonably cool conditions. It will feel more like the middle of April than early June. We do need the rain, as May was rather dry, but that probably won’t make you feel much better if you need to venture outside on Monday. High temperatures will only be in the 50s (possibly even upper 40s), which is 15 to 25 degrees below normal. Add in winds of 10-20 mph, with gusts to 30 mph, especially along the coast, and well, Baseball Hall-of-Fame pitcher Dennis Eckersley said it best – “Yuck.”
The coastal low pulls away Monday night and the rain tapers off, so everything gets better on Tuesday, right? As ESPN college football announcer Lee Corso is fond of saying:
Sure, the system will pull away, but an upper-level low pressure system will slowly move across the Northeast Tuesday into Wednesday. As impulses of energy rotate around that upper-level, another surface low-pressure system may even spin up. Whether that happens or not, we’re looking at plenty of clouds along with more showers and drizzle into midweek. Temperatures will remain below normal, but not as chilly as today will be.
By Thursday we really do see some improvement. The upper-level low moves out, and high pressure starts to build in, both aloft and at the surface. That means sunshine returns, and temperatures get back closer to normal. Friday should also feature sunshine and warm temperatures. That brings us to the weekend.
Saturday may actually turn out to be a decent day, though a cold front will move through, with some showers or even a thunderstorm possible. The front stalls out just south of the region later in the day, and a wave of low pressure will ride along it. Right now, it looks like that wave will bring in more rain and cool conditions Saturday night into Sunday. Obviously, this isn’t locked in yet, but given the way weekends have gone for the past month or so, would you really be shocked if we had another less-than-optimal weekend? We will break that pattern eventually.
Will the rest of summer feature weather like this? Will it be a scorcher? Or somewhere in between. Our colleagues at Hometown Forecast Services (official employer of StormHQ), issued their summer outlook a few days ago. If you’re interested, give it a read.
