HIGHS TODAY…
Wednesday will be hot- but not AS hot as yesterday (we hit 96° in Boston yesterday) West winds will push heat to Boston, and the North and South Shore with highs around 90° near records for the date. Mid to upper 80s to the N&W #WCVB pic.twitter.com/dddysBYKmw

T-STORM RISK…
Best chance of t-storms today will be near and south of the pike with SE MA the most likely spot for a severe storm. This is farther south than yesterday's storms which brought lots of wind damage near and north of the pike #WCVB pic.twitter.com/1kEIHUkkNb
