A severe thunderstorm watch is in place for most of the WTEN viewing area through 9PM EDT tonight.
A severe thunderstorm WATCH means severe thunderstorms ARE possible. (A severe thunderstorm warning (when/if issued) means severe weather IS occurring.)
Warm and humid air over the area is being disturbed by a stationary front that has aligned itself across NYS along the Thruway.
Main threat appears to be damaging wind gusts. However storm mode/type appears to initially be supercellular in nature; these supercells could cause some isolated large hail of 1"-2" in diameter. As these supercells develop through the evening they are expected to merge with each other into small multi-cell clusters that will move from NW to SE or WNW-ESE across the the watch area producing damaging winds and some marginally large hail.
Please keep in mind ANY severe thunderstorm CAN produce a tornado. However this said the tornado risk/threat for us for today's POSSIBLE severe weather is very low. The primary threat appears to be damaging wind followed by a large hail threat.
Also keep in mind ANY thunderstorms can produce dangerous and deadly cloud to ground lightning and very heavy rain in a short period of time. It is possible that any storms today could produce rainfall of 1"-1.5" in an hour or less. This could cause some local flooding in poor drainage areas
