The National Weather Service has issued a severe thunderstorm watch for all of Central New York until 9pm.
A low pressure system off to our west is expected to bring some much warmer air into the region tomorrow and with it comes the unstable condtions needed for scattered thunderstorms to develop. Some of these storms could become severe. Right now The Storm Prediction Center has the majoirty of our viewing area under slight risk (See classification chart).
The primary concern is wind gusts. If severe storms develop we can see wind gust between 60-70mph. That is strong enough to see some structural damage, downed trees, and power outages.
Cloud to ground lightning is anticipated in Sunday's storms so if you hear thunder make sure you head indoors. Large hail can also occur in these storms. The possibility for an isolated tornado cannot be ruled out at this time.
Locally heavy rainfall may occur and, since soils are already wet from plenty of rain this spring, with possible to see flooding for small streams, urban/poor drainage areas, and roadways. Isolated flash flooding cannot be ruled out.
As of right now the greatest risk for severe weather looks to be between 1PM to 10PM on Sunday. However, there is an additional chance for some more severe weather Sunday night. Make sure you stay updated on the forecast throughout the day, especially if you have outdoor plans.
