Friday AM Shower/Rumble of Thunder
It's a mild morning out there with temperatures running in the mid to upper 50's already. There are a few showers and thunderstorms moving across Southern New England (SNE) right now.
The cell moving along the CT/RI coastline has produced several lightning strikes. The bulk of the activity looks to be in CT, RI, and SE MA including the Cape and Islands. Here is the future radar from 7 AM to noon time.
Just looking at the current radar I think this is overdone a bit. I'm not sure the extent will reach Boston. A cold front to our west is responsible for the increase in temperature and moisture this AM. The front is weak and it will fall apart as it reaches the Atlantic.
The skies will clear by the late morning across interior SNE and for most of the region away from the immediate coast by 2 PM.
This will allow for temperatures to reach the mid to upper 70's. A few locations in the traditionally warmer spots will reach 80. My money is on Bedford, Westfield, or Lawrence.
The air mass behind this "cold front" is nothing of the sort. Tonight temperatures will only fall to around 60. Dew points will be on the rise after midnight. If you have early Saturday AM plans be prepared for a batch of rain tomorrow. The timing would be between 6-11 AM. The greatest threat is north of the Pike, but a few showers will cross the southern zones as well. The is a low threat of lightning with these showers.
Once high-pressure nudges this system offshore it will a very nice Saturday PM. Max temperatures will be in the mid to upper 70's, Winds will gust 20-25 mph at times.
High pressure will keep the front south of the region on Sunday. Expect seasonable weather with temperatures in the low to mid 60's. The cool wind out of the north and a cool upper atmosphere may produce a spot shower or two Sunday PM, but should be partly cloudy for the most part.
Enjoy the weekend, talk to you all soon.
