July is definitely going out on a cool note. The last seven days have featured below normal temperatures at the Portland Jetport and all indications are for another cool day on Thursday. It has also been a wet month with above normal precipitation totals and we stand a good chance of adding to those totals before the month ends.
A trough of low pressure is expected to swing across New England Thursday kicking off showers and thunderstorms. These will be hit or miss but could contain heavy rainfall and possibly some small hail. Before they get here we'll see partial sunshine after any morning fog burns away.
High pressure will build in for Friday so August should get off to a pretty nice start with sunshine and temperatures pretty close to normal. The high will then give way to an approaching warm front on Saturday and this should lead to more clouds along with a chance for showers or thunderstorms. The front is expected to stall to our south keeping our weather very unsettled right into next week.
