Showers and thunderstorms developed on the frontal boundary, bringing a round of heavy rain to portions of central and southeast New Hampshire during the overnight hours. Rainfall amounts during the overnight hours generally ranged between three-quarters of an inch and one and one-half inches across the abovementioned area. The additional rainfall sparked flooding in Auburn New Hampshire, prompting the issuance of a flash flood warning for rockingham county. At 400 am, another batch of heavy rain was moving across the same region. At the same time, clouds and widely scattered showers dotted the remainder of New Hampshire and Maine. Temperatures were generally in the 60s during the overnight hours. The frontal boundary will stall south of the region this morning. Another batch of showers will affect mainly central and southern sections today. With cloudy skies and a light onshore flow, highs today will stay in the 60s. Low pressure developing on the frontal boundary to the south will spread another swath of rain across the region tonight. The rain could be heavy at times late tonight and Saturday across southern New Hampshire and southwest Maine. Should the heavy rain materialize, there will be a flooding threat. With clouds and an increasing onshore flow, temperatures Friday night and Saturday will not change much, with readings mostly in the 50s to near 60°. As the low pulls away Saturday night, the rain will taper off from northwest to southeast. Clouds will remain in place, and winds will start to diminish. Lows Saturday night will drop back into the 40s and 50s. The clouds and shower threat will linger into Sunday for much of southern New Hampshire and southern and eastern Maine. Elsewhere, the sun will make a return. The clouds will keep temperatures mainly in the 60s, which is a few degrees lower than normal for early June. Weak high pressure building up the mid Atlantic states will bring drier conditions for Sunday night and the beginning of the upcoming week. === The weather observed at WHITEFIELD, NH at 09:52 AM EDT was: === The skies were clear.
