I can say with fairly high confidence that yesterday was the last time we will see widespread highs in the 90’s until next summer. That was brutal! For those who join me in disliking air you can drink, there’s a lot of good news in the forecast this week, beginning today. A warm front will approach the region this morning with a scattered shower or two possible. Sun currently being seen this morning is likely to give way to overcast skies by mid day. Winds will become breezy out of the SE by this evening which will move marine air well inland. As a result, highs will be uniformly in the 70’s with low stratus and some fog possible especially towards this evening. Showers and thunderstorms will approach the area from the west later this evening and into the overnight hours. The soupy airmass that will be in place by then (PWATs near 2″) will lead to the greatest threat being from heavy rain. The stable marine layer will limit any severe threat though with impressive jet dynamics a stray wind gust can’t be ruled out over Western NH. Rumbles of thunder are also possible.
Looking ahead, brisk (30mph) NW winds will bring in cool, dry air tomorrow. This lovely airmass will stick around through Monday and Tuesday will be warmer with SW winds. This, however, will be brief as a strong cold front, the strongest we’ve seen so far this season, will slice through the area Wednesday evening with crisp air for Thursday into the weekend. A slow warming trend is likely for the weekend.
