Mother’s Day Sunday will have us feeling like we are well into the summer season! High temperatures will be rising into the mid and upper 80s along with a bit of mugginess as dewpoint temperatures approach 60 degrees. Even the coast will be warm with a dominant southwesterly breeze, only the immediate shore roads will be the coolest in the low to mid 70s.
Unfortunately, the weather conditions will not be the best for all locations during the course of the day. There will be developing threat of showers and thunderstorms starting in the north country around noontime and early afternoon as a cold front moves into the region from Canada. As that front continues to sag southward during the late afternoon so will the scattered showers and thundershowers. Therefore, between 4-9pm southern New Hampshire will be under the greatest threat of those showers/thundershowers. That being said, we could definitely use the rain!
The cold front will settle south of New England for Monday evening then bounce back north as a warm front Tuesday morning while a wave of Low pressure moves along the St. Lawrence valley Tuesday afternoon. All this activity will keep the risk of scattered showers going for Monday and Tuesday. Once this sweeps through, a brief return to cooler more seasonal air in the 60's is expected for the midweek while High pressure builds in from Canada. As we head towards next weekend it looks like another warm up will be on the way!
Have a great Mother’s Day!
