Temperatures have been running on the cool side since this week began, but we are in the midst of an airmass swap.
The stubborn upper level low that has been dictating our weather is now heading northeast. The jetstream will take a more zonal position and flow starting tomorrow.
Today will bring us lots of sunshine and high temperatures returning above-normal into the middle or upper 80s, near 80 on the Cape and Islands. I am keeping southern New England dry today while there will still be a slim chance of an afternoon storm across northern New England to points as far south as SE New Hampshire/NH Seacoast.
Friday may begin with some debris cloud cover from a mesoscale convective system that is projected to develop tonight along a warm front. Then, there will only be a slim chance of a spot afternoon storm. Otherwise, it will be partly cloudy with highs around 90! This may be the beginning of heat wave #2 this year.
Saturday, the last day of June, will be loaded with sunshine as the heat surges into the lower and middle 90s. This will be challenging the current records Boston’s is 95, set back in 1945 and Worcester is 92, set in 1971 (tied with previous years).
Although the jet stream flow makes it tough to 100-percent rule out an isolated storm, I am willing to say that nearly everyone will enjoy a dry day.
Sunday, July 1, will be partly cloudy with a chance of a few showers and storms, especially near southeastern Massachusetts. Highs will stay near 90.
The beginning of the week of July 4th will be unsettled with showers and storms on Monday and possibly into midday Tuesday.
Then, models are hinting at a sunshiny 4th of July ’12! :)
One alarm clock away!
