MEMA, the Massachusetts Emergency Management Agency issued a warning at noon on Wednesday for increasing heat and humidity (their map shows Bedford with a heat index of 101 degrees for both days), along with heavy rains to follow the heat.


After Wednesday’s rains move away, MEMA predicts hot and very humid weather from  Thursday through Saturday.  Heat watches/warnings will likely be issued.

Friday through Monday rounds of showers and thunderstorms are expected with at least locally heavy rainfall at times.  There will be the risk for localized urban flooding with the highest risk this weekend (despite the current drought conditions).


  • Heat Advisory issued for much of eastern MA Thursday, where we are most confident in the Heat Index reaching 100 to perhaps 105 degrees Thursday afternoon.
  • Afternoon heat indices could reach 100 degrees elsewhere, with the exception of the immediate South Coast, Cape Cod, and the Islands.

Localized Heavy Rainfall

  • Highest risk Sunday – Monday.
  • Periods of on/off showers and thunderstorms could yield localized heavy rain.
  • Urban flooding is the primary concern.
  • There is still uncertainty as to where the heaviest rain will fall. It could end up north or south of our area.

Extreme Heat Safety Tips

  • Never leave children or pets alone in a closed vehicle. Even with the windows cracked open, interior temperatures can rise almost 20°F within 10 minutes.
  • Check with your local authorities or Call 2-1-1 to find locations of cooling centers or shelters near you.
  • Know the symptoms of and watch out for heat-related illnesses. Call 9-1-1 to report emergencies.
  • Be a good neighbor. Check on family, friends, and neighbors, especially the elderly, those who live alone, those with medical conditions, those who may need additional assistance, and those who may not have air conditioning.
