Nice weather from the weekend spilled over into today but unfortunately it won’t have the legs to make it through the entire week. A coldfront is marching our way from the west. This coldfront is expected to pass through tomorrow with heat and humidity building out ahead of it. The timing of this front is still a bit in question which makes timing the thunderstorms more difficult. But my feeling now is that it will be sliding through midafternoon in Eastern MA. This moves the focus for storms from Western New England to Eastern New England for tomorrow afternoon and early evening. This also allows for the potential for some dangerous thunderstorms to develop along the front with large hail and damaging wind gusts along with cloud to ground lightning and very heavy rain. If you have outdoor plans tomorrow afternoon please be aware that you may need to take shelter if storms approach.
Following tomorrow’s storms, the air will dry out very nicely Tuesday night…NW winds will draw down very comfortable air from Canada and setting up Wednesday to be the best day of the week with sunshine and a high near 80.
unfortunately, a shortwave trough will approach from the NW for the second half of the week inducing weak surface low formation over the Northeast for Thursday and Friday. This will mean showers and thunderstorms will be likely as we finish up the workweek. With downstream blocking over the Atlantic strengthening, the trough will stall over New England keeping unsettled weather around for the weekend as well. In fact a new surface low will likely form and spread showers back in by Saturday afternoon and lingering showers can be expected on Sunday too…only slow clearing should occur by Sunday evening. Looks like our string of beautiful weekends will come to an end.
