The pattern is shifting and evolving into one that promotes drenching thunderstorms from time to time and it will try to hold deep into next week. The heat from earlier in the week has been beaten back to our south by a backdoor coldfront that ushered in some chillier air…temps today hovered mostly in the 60s for a change! That front will work back through the area on Friday. Along the boundary, an abnormally deep area of low pressure has developed for this time of year and the result is very heavy rain with embedded thunderstorms. Most of this rain will miss us to the west, but the fringe will get us late tonight and early tomorrow morning with potentially flooding downpours. The flooding we are talking about is temporary street and parking lot flooding…small creeks and streams will rise rapidly in any downpours as well.
The low lifts out in the morning and temps will climb into the upper 70s to around 80 with the passage of the warmfront. Breaks of sunshine will also occur but could lead to additional pop-up soaking storms in the afternoon and evening especially in Western New England.
The jetstream is going to get bottled up and locked in an unstable pattern with a trough to our west and a ridge to our east. This will funnel very warm, moist air up the Eastern Seaboard and with a front very close by soaking showers and storms will be possible each day going into next week.
