Weather summary: What makes the weather so fascinating sometimes are the incredible changes we can have in such a short period of time. We all knew it was coming but it was still hard to take for most, with temperatures climbing into the mid 90s and dew points in the low 70s on Wednesday. This made for heat indices in the low 100s during the afternoon hours under a blazing sun. That is brutal heat and especially difficult for folks with respiratory issues, elderly, very young and those that have to endure working outdoors.
Then we had an especially warm and muggy night, and for those without air conditioning a difficult night trying to sleep. Temperatures remained in the low 90s until about 9 p.m. and gradually fell through the 80s overnight. The morning sunrise lows start out in the mid to upper 70s.
Weather synopsis: Thursday will be a repeat of yesterday, with intense heat, high humidity and scorching sunshine. Heat Index temperatures will reach into the low 100s once again. A cold front will approach New England late Thursday night and Friday and spell relief for the area by later Saturday. Ahead of the front we should see more clouds on Friday, with showers and thunderstorms developing. The showers and thunderstorms continue into Friday night as well. Some storms could become severe.
The cold front will be slow to move offshore late Friday night and early Saturday morning. This could hold clouds in for a good portion of Saturday, with a spot shower or two. High pressure will make a brief visit later Saturday and early Sunday, bringing partly cloudy skies, cooler temperatures and less humidity to the area.
As we approach the end of the weekend and early next week a weak disturbance will be the next feature to impact our weather. We could see a period of showers beginning late Sunday or Sunday night, lasting through Monday night. Early next week might see a return to slightly cooler than normal temperatures.
High temperature recap for Wednesday: Logan International Airport in East Boston recorded a high temperature of 97 degrees, which fell short of the record high for the date of 98. Other unofficial highs in the forecast area were 97 in Wakefield and Bedford, 96 in Amesbury, Saugus, Ipswich and Walpole. It hit 95 in Lawrence, Waltham and Natick, with Marlborough reaching 94.
For the second day in a row the National Weather Service has issued a Heat Advisory for our area. http://www.erh.noaa.gov/box/hazardsByCounty.php
