7-Day Outlook: Wednesday, June 11 – Tuesday, June 17
Wednesday – Friday
Surface high pressure will build up from the Mid-Atlantic region today as the cold front that brought yesterday’s rain departs in the Maritimes. Cool air aloft along and some mild instability will allow for breezy winds to mix down today with gusts in the 25-30 mph range over much of the Saint John Valley.
An isolated shower or thunderstorm may occur this afternoon; however, widespread precipitation or severe weather is not anticipated. A cold front approaches tonight from the northwest bringing increased cloudiness and a chance of showers and isolated thunderstorms overnight.
The cold front crosses the Valley Thursday morning with partly sunny skies and breezy west to northwest winds across the area. An upper disturbance crosses the area Thursday keeping a chance of showers and isolated thunderstorms possible for the SJV. Showers/thunderstorms end with the loss of daytime heating and Thursday night looks partly cloudy and cool as high pressure builds into the region.
Friday, high pressure spreads across the Valley with partly cloudy to mostly sunny skies. Friday night looks partly cloudy and cool with near calm winds as high pressure will be overhead.
Saturday – Tuesday
High pressure currently looks to remain in control of the Valley’s weather Saturday as it moves into the Maritimes and continues to dominate the region’s weather Sunday. A frontal boundary will be located south of the region; however, its exact position is somewhat uncertain, but any precipitation looks confined to coastal/southern Maine. A disturbance in the northwest flow aloft will produce a slight chance of isolated shower activity in the north Saturday afternoon.
Otherwise, Saturday night through Monday night look to be quiet with partly cloudy skies overnight and mostly sunny skies in the day as high pressure continues to control the area’s weather. Partly sunny skies develop Tuesday as a cold front approaches from the northwest bringing a chance of showers to the SJV later Tuesday into Wednesday.
