Areas affected...portions of Maine into New Hampshire
Concerning...Severe Thunderstorm Watch 490...
Valid 301921Z - 302115Z
The severe weather threat for Severe Thunderstorm Watch 490
continues.
SUMMARY...Severe thunderstorms producing strong/damaging gusts
remain possible across southern New Hampshire into coastal and Down
East Maine.
DISCUSSION...The strongest convection ongoing this afternoon is
along a pre-frontal surface trough and within the axis of greater
instability and low-level moisture. A line of strong to severe
storms producing wind damaging will continue to shift east/southeast
across Down East Maine the next couple of hours. Additional more
isolated convection is ongoing across New Hampshire and will shift
into coastal Maine, also posing a damaging wind risk. Additional
storms may move into northern Maine in association with the synoptic
cold front. However, cooler temperatures and lower dewpoints are
resulting in weaker instability with northward extent, and severe
potential will be a bit lower compared to further south.
