Weather: Active Tropics, Quiet Northeast (9/19/2017)

News
Planner for Wednesday September 20 2017

Tuesday night, isolated light showers continue in southern Vermont & New Hampshire. Meanwhile, the North Country remains mainly dry but partly to mostly cloudy with lows near 60°. It’s less humid than Monday night but areas of fog will still be possible; some will be thick near rivers. Wednesday, clouds and leftover showers remain stubborn in southern Vermont & New Hampshire but gradually end as Jose shifts east and south during the day. Humidity will stay down but we’ll stay warm with highs well into the 70s. Overnight lows into Thursday will be in the middle & upper 50s. All the while, we’ll all be dry and quiet with areas of fog by Thursday morning.

High pressure will build in from west to east Wednesday afternoon and stick with us through the beginning of next week! That means a prolonged stretch of sunshine, highs in the 70s & 80s and lows in the 50s & 60s. In fact, there are now signs of a big dome of heat building by Sunday. Some of us have the chance at touching 90° Sunday and Monday. Fall officially starts at 4:02pm on Friday, Mother Nature has other plans.

In the tropics, Jose, now a tropical storm with max sustained winds of 70mph, continues to spin in the northwest Atlantic. Jose’s largest impact remains big waves (5-10′), coastal erosion and dangerous rip currents from the Mid-Atlantic to Maine. Highest inland rain totals should remain around 1-2″ in southeastern Massachusetts. The center will stay well offshore through the weekend but the fact that it’s meandering for a while means the ocean will stay agitated for several more days. Your beach plans might get canceled. It’s interesting to note that Jose was a hurricane for 12 days. That’s good enough to make it the longest lived hurricane in the Atlantic Basin since Hurricane Frances in 1980.

Hurricane Maria is a monster category 5 hurricane. As of 11pm Tuesday night, the pressure remains 909mb making it one of the top 10 strongest (by pressure) hurricanes on record. Sustained winds are at 175mph with gusts near 200mph.

It will be a life threatening storm that moves dangerously close to St. Croix Tuesday night before hitting Puerto Rico directly on Wednesday. Maria will then continue northwest, grazing Hispaniola on Thursday. It’s expected to take a northerly turn Thursday night & Friday causing it to miss Florida but the rest of the east coast must watch Maria close.
