….THE RAIN IS ABOUT OUT OF HERE, AFTERNOON SHOWERS? SPLENDID WEEKEND….
The third storm of our 3 storm trifecta over the past week is upon us and things seem to be performing just about as expected after a week of indecision among the computer models. As depicted yesterday this system has moved right along after emerging from the Ohio Valley yesterday. Presently low pressure is redeveloping just south of Long Island and we’re seeing a pretty substantial shield of rainfall move through New England as a result. The good news is the back end of that slug of rainfall is now moving into SW RI, Central Massachusetts and SW NH. Rain is starting to ramp up in SE and Central ME.
I expect that the main area of rainfall should be mostly out of MA/RI and NH by 10-11 am. Rainfall will continue into the state of Maine with the back side of that main shield of rain moving through the state by early evening. As this afternoon rolls on an area of low pressure in the upper atmosphere will move over New England and that should leave the clouds locked in and there is the risk of further shower activity developing in Southern New England during the midday and early evening hours.
All of this weather activity will finally come to an end by Saturday morning as the upper level trough axis pushes offshore and is replaced by a ridge of high pressure which should supply ample sunshine and fairly calm weather for Saturday.
On Sunday, a weak wave of low pressure will track through New England and this may generate a few showers during the morning hours. It looks like this system will move through very quickly and the weather will quickly improve by Sunday afternoon.
By Monday another upper level low will settle over the northeast and while I don’t think it will bring much in the way of shower activity with it, it will keep things a little cooler on Monday in comparison to the warmer weather that I’m expecting for Saturday and Sunday.
In the longer range, the next weather maker of any real significance will move into New England Wednesday afternoon into Thursday morning.
