Strong Thunderstorms Likely Today 

Hello everyone! 

Today will feature hot temps, stifling humidity, and thankfully the chance for some big boomers this evening. Highs today will soar into the mid to upper 80’s north and east with low to mid 90’s south and west. More important than the temps will be the dew points which will climb to oppressive levels today. Dew points will rise into the upper 60’s north and low to mid 70’s south. The incredibly high dew points as well as incredibly high precipitable water values (PWATs today are around 2″ which is about 2 standard deviations above normal) indicate that there is a ton of moisture in the air. This means that with any storms today, heavy rain will be the primary threat. Storms will develop to our west this afernoon and will be moving into western NH by 3-4 this afternoon. Storms will continue to track east and slowly weaken through the evening reaching the coast by 6 or 7 PM. NH and far western ME are at risk for damaging winds in storms today. That threat diminishes as you head east and by the time you get to the midcoast, a rumble of thunder and some benefitial rain is likely to be the extent of the impacts. Winds will be out of the south today which will be the limiting factor in terms of both temps and storms especially east of Brunswick.
