Today will feature afternoon showers and thunderstorms as a very slow moving cold front drifts in our direction from the northwest. Look for a mix of sun and clouds this morning with increasingly warm and humid conditions developing. A few showers will move through Southern NH this morning, but otherwise mostly dry conditions are expected for the next few hours.
As we move into the afternoon hours, expect showers and storms to begin to pop up over the mountains. Winds in the mid to upper levels of the atmosphere are fairly light today, so storms will move slowly, and severe weather is not expected to be a major issue. The primary threats from these storms will be torrential downpours and lightning. Due to the slow storm motions, those downpours could linger in some areas, creating a flash flood risk. This risk is greatest in the mountains. Storms will weaken as they drift closer to the coast tonight. Highs will range from around 70 along the coast to around 80 inland.
