DISCUSSION...A strong cold front is moving south across northern Vermont, New Hampshire and Maine with temperatures in the upper 50s in its wake. Strong heating is occurring ahead of this cold front with temperatures in the upper 80s and dewpoints in the 60s across southern New Hampshire and southern Maine. Taller cumulus have started to develop along the front as it crosses the White Mountains. Within the next 1 to 2 hours, expect storms to develop along the front as it moves into the hot airmass east of the terrain. Cooling temperatures aloft and strengthening mid-level flow will provide an environment favorable for a few strong to severe storms this afternoon before the front moves offshore. Overall, the limited instability and relatively confined threat area near the coast should limit the need for a severe thunderstorm watch. ...Bentley/Mosier.. 08/17/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!4Bin0IXEAUTSQqr_cw2YxKtSiReAI8MaYwSRp-qswbmhcZ8rb-33FkoaWvzqUI-PuLjStbzfp= ixYafirbRb8sfRy9Mg$ for graphic product...
