4 Down, 1 To Go
Posted by Chris Lambert
The high temperature of 93 degrees in Boston, was just a couple degrees shy of yesterday's 95, thanks to a few more clouds that bubbled up this afternoon. However, it was good enough to mark the 4th consecutive day of 90 degree weather in the city, with tomorrow, likely being the 5th.
Despite some clouds building this afternoon, showers were few a far between as the atmosphere had little "lift" to it. Those clouds were driven by a convergence of air as winds turned from the southwest to the west-northwest. Once the winds turned to the west or west-northwest, dew points lowered into the 60s. Did you notice the difference?
It looks like tomorrow's forecast is similar to today with highs in the lower 90s, sunny to partly cloudy skies and an isolated storm possible. Rain chance tomorrow runs around 20%, so don't expect the storms to be widespread. Afternoon dew points run in the low to mid 60s, so heat indices should stay just below 100.
Monday features a better chance for storms as upper-level energy rotates on in. The highest threat for widespread storms is just north and west of Boston, but even in city, we have a decent shot of getting some afternoon rain in here. SE Mass, the Cape and the Islands have the lowest rain chance.
I realize you don't like to cheer on rain during the summer, especially if you have the day off, but after 5 days of 90 degree heat and no rain, the lawns and gardens will appreciate it. Highs still reach the upper 80s Monday, so while we likely break our heat wave, it'll still be warm.
Tuesday's rain chance is lower, but we'll increase the storm threat again starting Wednesday. While I have a lot of thunderstorm icons in the 7-day from Wednesday on, there will be breaks of sun and warmth each day as well.
