90° days have been common inland during the second half of July. More hot weather is ahead for the next couple of days before a storm system brings some rain at the end of the workweek.
There is a good chance that the temperature will reach 90° inland Wednesday and Thursday. Boston and Hartford are looking at 8-day heat waves before it breaks on Friday. A cooler breeze will be felt at the coast, especially on Wednesday, with highs in the low to mid 80s. It does not look very humid either day, and there will be tons of sun on Wednesday followed by partly cloudy skies on Thursday.
It’ll be a close call with moderate to heavy showers on Friday afternoon and night. Some models are bringing more than an inch of rain to RI and SE MA, but other projections are for much less – 0.25″ at most. The setup is decent for at least 0.5″ rain in some places, but it may not be widespread. Also, in this situation, there could be a narrow strip of very heavy rain. There’s ample moisture in the summertime air.
A break in the action is in the forecast for Saturday. It should be a partly cloudy and seasonably warm and humid day. Highs will be in the 80s. A second storm system may come close enough for rain or showers on Sunday.
Looking ahead to early August, it should not be as hot as the second half of July was. Highs will likely be in the upper 70s to mid 80s for several days in the early to middle part of next week.
As we hit August it’s times to turn our attention to the tropics, and the 15 day outlooks from the GFS and European models are very quiet in the Atlantic Ocean and Gulf of Mexico.
