Severe Weather Today

1621 300 ORANGE GRAFTON NH 4365 7197 3 INCH HAIL AT MT CARDIGAN (GYX)

Three inch hail at Mt Cardigan!! That's softball sized hail, something that rarely happens in this area. Another report...

1707 UNK ALEXANDRIA GRAFTON NH 4361 7179 TREES DOWN ON MT CARDIGAN ROAD.

Unknown wind gust knocked down trees on the road leading to Mt Cardigan. A tornado warning was issued with that storm, that has since canceled, but more severe weather is possible this afternoon. Id be willing to bet that NWS crews will be checking for tornado damage near Cardigan soon.

Storms are pretty much moving from south to north, or just slightly east of north, so we are under the gun the rest of the day. Plus, there are more showers and thunderstorms developing out in upstate NY and we may have to hear from those later this evening.

Looking at doppler radar rainfall estimates, it ranges anywhere from around .6-.75 inches in Hanover, (.57 officially at Lebanon airport) to 2 inches around Orange and Alexandria (Mt Cardigan area), and up to 2.5 inches near Laconia. So any storm that develops has the potential to produce flash flooding. The storm that was near Mt Cardigan produced 1.85 inches of rain in ten minutes...not a typo.

As for now, thunderstorms are possible at any time of the afternoon, so keep watching the sky if you have outdoor activities. Currently there is a batch of very heavy thunderstorms east of the area, and a few south and west of us, trying to develop. Those are moving in our general direction.


edit
A brand new severe thunderstorm watch was issued for upstate NY over to southern VT. That may be extended further east later today. We'll watch it. The rain cooled air may serve to temper the storms later, but if there is any sunshine this afternoon, it will only further destabilize the atmosphere.
