Heavy rain, thunder approaching

Heightened instability over central New England has allowed the complex approaching from the west to instensify. While not at severe levels, there are multiple embedded cells featuring heavy rainfall. These cells are relatively slow moving. Radar estimates indicate a swath of .8 to 1.2" per hour rainfall rates over southern Vermont. Extrapolating the core of the heavy rainfall places it just south of Keene by 1:15pm. If driving at this time, be prepared for sudden downpours and rapidly lowered visibility.
