NH1 First Alert Weather: September 25, 2017
Written by NH1 Weather on .
Unseasonably warm weather will continue Tuesday as high pressure slides east. We will likely see a few more pop up isolated showers mainly over the mountains and higher terrain. Highs will generally reach the mid to upper 80s in inland locations with sunny to partly sunny skies.
Once again a sea breeze will cap temps in the mid 70s to near 80 along the coast.
Another warm and muggy night on tap for Tuesday night. Expect any lingering early evening showers to clear. More dense fog will be likely in valley locations. Lows overnight will range from the upper 50s to mid 60s.
A continuation of the early fall heat lasts through Wednesday with once again widespread temps in the mid to upper 80s nearing 90 with a mix of sun and clouds and risk of a spot shower. This kind heat would be enough to see a few more records fall as well. In addition to the heat, we will have higher dew points too. And this is likely to lead to afternoon instability and the risk of pop up PM thunderstorm, and maybe the potential for a stray strong to severe storm.
After the cold front pushes through the forecast area Thursday morning, high pressure from Canada settles in. This will bring much cooler and drier weather for the end of the week and weekend. Given how warm it has been though, this is forecast to just bring temps back toward normal ... 60s to near 70.
