2:45PM UPDATE: This storm seems to becoming more of a small
line. The hail sizes my software is recording are deecreasing
as well. What that means is the wind threat is probably
increasing as opposed to the hail threat. Also, the 3PM the
NWS has listed for an arrival time in Groton is way off.
3:30-4PM is still a better estiamte.

SEVERE THUNDERSTORM APPROACHING GROTON
From the National Weather Service:
Severe Weather Update: 2PM
Things have really fired up in the past few hours. As I stated earlier, multiple lines have formed, all to our west, meaning our chances for severe thunderstorms are pretty good. A Severe Thunderstorm Watch is in effect until 9PM. There are multiple areas to watch, so here is the breakdown:
Closest to the Groton area now are a few individual cells. There is one just south of Auburn, and another west of Trumansburg. They are moving towards the east northeast and probably contain some hail. The storm west of Trumansburg will be a close call for Groton. According to my storm tracking software, this storm has hail up to 2" and would probably reach here between 3 and 4 PM. Anytime you get individual cells out ahead of the line on a day like today, it needs to be watched for rotation. I will update on this storm again towards 3PM. Here is the screenshot of my storm tracking software. Groton is marked by the diamond that says "Grotonweather" towards the right. Click the image for a larger view.
Not far behind these cells is the first line of thunderstorms. Wind damage reports are already wide spread through Western New York. This line will move through not long after the cells clear the area, probably between 3:30 and 4:30. The main threat with these storms will be wind damage.
Further to the southwest, over Pennsylvania, there are more scattered cells. These need to be watched in case they form another line. More on those storms as they develop.
Lastly, there is another line of storms over eastern Ohio and Ontario. This line is along the cold front and probably won't move through until after sunset. Because it will have lost the day time heating, its severe threat will have greatly diminished.
Keep checking back as the storms continue to approach and develop!

Severe Storms, New Features coming
Another round of severe thunderstorms will be coming to the area later, probably during the late afternoon and early evening hours. There is also some non-weather news, as I have once again been working on improving grotonweather.com. Read on for more!
Another powerful cold front will come through the region later this afternoon and evening. Temperatures ahead of this front will be in the low 90's and humid, providing fuel for the storms. It looks like multiple lines of storms will form during the day. While one of these lines is already forming well to our west along the cold front, it is any one's guess where the other ones will form. If they get going to our west, our chances for severe weather are much higher. If the lines form to our east, I don't think the line along the cold front will retain its severe levels by the time it reaches here, probably after the sun sets. The main severe threat will be wind and hail, though the conditions appear favorable for a brief tornado or two, especially to areas east of I-81. Even though the largest severe threats appear to be west and east of Groton, the situation should be watched and I will updating as needed throughout the day.
School is out! Congratulations to my fellow classmates as we graduate Saturday (which should be an absolutely perfect weather day!) Since school is out, I have time on my hands. I have been using some of this time to once again upgrade and improve grotonweather.com! I have been conducting a survey (which I would still love for you to take by clicking here) and it quickly became evident that a more regional forecast would be helpful. So, I have been working on how best to include a broader look at the weather. I have it pretty much figured out and just have a few kinks left to work out. While its not ready to be viewed and updated, I did take a screenshot of what it looks like so far. Take a look (click for larger view):
