***OUTDATED SEVERE WEATHER POST, THE INFORMATION HERE IS NO LONGER VALID.***
We now have a FIRST ALERT DAY issued for Tuesday. There is a risk of significant severe weather. Please read this post carefully and visit the link I have shared if you do not understand what it means.
There is a relatively rare Day 3 hatched area also, mainly north and west of Binghamton. This usually doesn't happen probably more than 2 or 3 times each year.
A hatched area (black slashes) indicates the SPC has placed a 10%, or greater, probability of significant severe weather in that area.
'Significant' is defined as: tornadoes rated EF2 or higher, Hail larger than 2" in diameter and/or winds 74mph or higher.
The percent values in the legend are probability ranges of seeing severe weather within 25 miles of any point in those areas.
The main threat in the hatched area this time would be for hail but depending on level of instability and the exact vertical wind profile, a strong tornado isn't completely out of the question.
Please download the WBNG STORMTRACK 12 weather app. I will be posting additional information on there later this evening.
