Based on the weather for the WCSH Sidewalk Art Festival's I've attended, I'd highly recommend planning an outdoor wedding on the same day. It's uncanny how nice it seems to be around this festival, leading many to suggest we have special weather powers . (Child please, if I had special weather powers I'd use them to influence sporting events, bet on said events and never work again...I've thought this through). There's a lot going on, beside just our own festival, this weekend and I'm happy to report the weather looks smashing.
A big ridge of high pressure has built into Maine overnight and it will provide us with a lot of sunshine and generally (I'll explain the "generally" don't worry) dry conditions until Monday night.
Today: Yesterday's cold front is now offshore (it was a wimpy front anyhow), leaving clear skies in the wake. With high pressure directly overhead I see no reason we won't remain mostly sunny through the day (#doublenegative). There will be an afternoon sea breeze so temperatures along the coastline will cool down late in the day, otherwise look for highs in the 80-84 range.
Tonight: Clear through the first half of the night with partly cloudy conditions by midnight. Lows will generally fall in the low to mid 50s with some cooler 40s over the mountains.
Saturday: Our general weather regime is unchanged: High pressure is still the boss. However there will be a warm front intruding into the northwest part of the ridge so I think we will see more cloud cover when compared to today. Still, it's an even mixture of sun and clouds at worst and temperatures will push into the upper 70s to low 80s. There is the SLIGHT chance of a mountain shower on Saturday afternoon as the winds push up the slopes. This will be entirely terrain driven, however, so the rest of the state will remain dry.
Sunday: Pretty much exactly the same as Saturday.
Monday: Sunny skies to start but clouds will increase by the afternoon ahead of an approaching cold front. The front will hold off at least until Monday night though so look for a dry day.
Monday night/Tuesday will feature some showers and thunderstorms as the front pulls through. It could drag its feet a bit so I'll keep an eye on some heavy downpours that could develop by Tuesday afternoon.
Isaac: Still looking pretty rough on the satellite imagery with overall poor organization. He has no shot of restrengthening until he re-emerges on the other side of Cuba. I'll tell you what though, from my experience forecasting Hurricanes at WSI back in the day, tropical cyclones get shredded (click that one, trust me) when they take this kind of path across the islands...so I'm wondering how poorly organized Isaac end up before re-strengthening occurs south of Florida. Either way the track has shifted slightly westward, putting landfall somewhere between LA and western FL on Wednesday morning. After landfall the computer models have NO clue what to do with the remains of Isaac. Some are advecting the moisture in our direction by the end of the week, others are just push Isaac back out to sea. No worries either way.
