Kickoff To Summer!
Gorgeous morning across New England with sunshine and comfortable humidity with dewpoints in the 50′s. Light WSW winds will warm temps to near 80-85 this afternoon with skies becoming partly sunny with a risk of a few isolated pop up shower or T’storm this afternoon. Extremely hit or miss, but models are showing the best chance will be in SNE especially along the MA pike. A light PM sea breeze along with a light West wind inland may help aid the surface convergence and lift to promote the building clouds and shower threat. There is not much instability in place so much of the day will be dry and pleasant.
High pressure will remain anchored off the coast through this first weekend of summer wrapping in light SW winds at the surface. This wind direction will allow for temps to gradually warm and for conditions to become more humid as the weekend progresses. A big upper level ridge is in place across the eastern US allowing for the warmth and humidity to build in the coming days. The flat flow to the Jetstream will come with embedded short waves which will provide just enough lift to trigger a few scattered showers or thunderstorms form time to time…almost everyday in the extended forecast.
Our next shortwave will be pushing from the Great Lakes into Northern New England Saturday. This will come with increasing afternoon clouds and a greater risk of scattered showers or a Thunderstorm during the afternoon, especially across northern and central New England. Highs will mostly average in the Lwr-mid 80′s on Saturday with a cooler breeze at the south facing coastlines. Sunday will be a similar day with a bit more humidity in the air, dewpoints will climb into the 60′s with highs in the mid to upper 80′s. A very warm summer day with again the risk of a pop up shower or thunderstorm….but less of a risk compared to Saturday.
By next week, the heat and humidity will be reaching it’s peak from Mon-Tues-Wed. with highs either side of 90..with hazy, hot, and humid conditions. Some areas will see a heat wave with 3 days at or above 90. Again, with the risk of a shower or thunderstorm everyday…The atmosphere will become more loaded with moisture in the coming days…so any t’storm which does occur will come with the potential for localized heavy downpours.
It is important to note that most of the time will be dry for anyone on vacation or with outdoor plans…so overall, we are looking at a classic summer pattern.
By Wednesday, a front will be pushing through which should begin to break down the heat, but will likely become stalled over us as deepening trough will be shifting east across the country as an upper low digs in from Canada across the Great Lakes. This should make for a more unsettled pattern of weather for the end of the week heading to into next weekend. There are also sign we may be seeing another tropical storm form in the Gulf by the end of the month which will help to inject more moisture into the overall weather pattern. This is something we will be watching further down the road.
Don’t forget to watch for the Full Super Strawberry Moon in the Weekend sky! This full moon is not only the closest and largest full moon of the year. It also presents the moon’s closest encounter with Earth for all of 2013. The moon will officially turn full on June 23 at 7:32 a.m….but both Saturday and Sunday nights should be good for moon viewing. The moon will not be so close again until August, 2014.
