Recent radar trends indicate that showers and isolated single cell thunderstorms are beginning to develop across Northern New York, Vermont, and New Hampshire. Currently none of these are that intense, however storms could get slightly more intense later this afternoon. Not intense enough to be severe though. The biggest threat will be heavy rain with the strongest of storms due to the fact they will remain nearly stationary or move very slowly. For tomorrow, thunderstorms will develop by late afternoon, as a low pressure system moves across the region, and slows down. Thunderstorms will lead way to a swath of rain, potentially heavy at times. The heaviest rain is currently forecasted to fall over Northeastern Vermont, and Northern and Central New Hampshire.
Rainfall Totals:
Widespread rainfall of 1-2 inches is expected with the area painted in 2-3 inches being more locally, and perhaps an isolated amount exceeding 3 inches over Northern New Hampshire. For the entire Champlain Valley and Southern Vermont .50 to 1 inch of rain is expected with significantly less as you go towards the St. Lawrence Valley. Thunderstorms though could aid in isolated higher totals.
Impacts:
For the most part the rain will be handled well across the area, but there is some elevated concern for area waterways in Northeastern Vermont, and Northern New Hampshire. Due to the recent wet weather we have had, and continued thunderstorms across Eastern Vermont, and New Hampshire, Flood guidance values are fairly low, so in areas that receive 2 inches within 12 hours could cause some flooding, and 2.5 - 3 inches within 24 hours could cause some flooding as well. For the most part any flooding should be minor. But as always, any thunderstorms that develop over the area will need to be monitored. Stay tuned for further updates. Below is a map of my forecasted rainfall totals.
