Well that was a fun day, I hope you had a least a few memorable moments outside in the lovely mid-summer air today. If you didn’t, no worries, yu will get another chance tomorrow…it’ll just be a bit warmer. Boston’s high was 74 degrees in the bright sunshine, it was the seabreeze that kept temps in the 70s at the coastline today. Inland towns mostly saw lower 80s…but with the air so dry it didn’t feel hot at all.
High pressure that delivered us this refreshing airmass from the Canada is working off the coast now and tomorrow we will see some return flow. This means that winds will be more SSW and will effectively warm us up another notch tomorrow then send the muggy air back our way for the beginning of the week. With the southerly wind highs on the South Coast and Cape Ann will hang in the mid to upper 70s but all others including Boston will climb into the 80s. With a touch more humidity it may feel a bit more uncomfortable for some.
On Monday, the humidity will be at uncomfortable levels and the heat will be on too. Those two, along with a pre-frontal trough will likely fire some isolated or scattered thunderstorms in the afternoon…at this time I don’t expect anything widespread but a few storms could approach severe levels.
Tuesday will be another day where we will need to keep a close eye on the radar as a surface coldfront will provide a solid focal point for more thunderstorm development. At this time the threat for those storms to achieve severe levels appears rather high. Thus, the beginning of the week may end up active with dangerous thunderstorms on back to back days.
