Spring 2011 Survey

Every year or so, I do a survey on Grotonweather.com. These surveys are extremely useful to me! They help me gauge how I am doing, what I can do better, what new features to add, and what old features should be removed along with other information. I never allow my surveys to go over 10 questions long so that I can keep it short and simple for you.

I would greatly appreciate it if you took a couple minutes and filled out the Spring 2011 Survey. Thank you very much for your time!

What does an "Alert Mode" mean?

Every once in a while, grotonweather.com will go into "Alert Mode" for various weather phenomenon. Flooding, heavy snow and severe thunderstorms are the three most common prompters of an Alert Mode. But what exactly do I mean by this, and how do I determine when to go into Alert Mode. This post will hopefully help you understand this better.

The Alert Mode is reserved for special instances of exceptionally dangerous weather that will impact the lives of those in and around the Grotonweather.com forecast area. The weather during an Alert Mode threatens lives and property. Precautions to stay safe need to be taken during these events. These are among the most significant weather events our area sees, and are accompanied by widespread watches and warnings issued by the National Weather Service. The Alert Mode is meant as another way to highlight the potential dangers.

Obviously, not every significant weather event is worthy of an Alert Mode, and the decision to send Grotonweather.com into Alert Mode is taken very seriously. Only a few Alert Modes are issued each year. A combination of things has to be taken into account when going into Alert Mode:

First, the weather needs to be significant enough to create widespread dangerous conditions. Every severe thunderstorm is dangerous, and even a little freezing rain can cause deadly automobile accidents. However, most of the time, these dangerous weather events are more localized events that most Central New Yorkers are probably used to. For an event to garner an Alert Mode, it has to be above and beyond the "average" bad weather situation.

Secondly, there has to be a good deal of confidence this life threatening situation will occur. Often times, Alert Modes are prompted during an evolving situation. Such is often the case with severe thunderstorms and flash flooding. These situations will also lead to shorter Alert Mode times, as the dangerous weather is often shorter lived. Other situations, including snow and some flood events, may have Alert Modes lasting days due to the prolonged nature of the event. Typically, these types of Alert Modes can be issued further in advance due to a greater certainty of the event occurring. Still, Alert Modes will almost never be issued more than 24 hours prior to the start of an event. Instead, Grotonweather.com will go into Standby to raise awareness of the potential for devastating weather.

When an Alert Mode is issued, pay extra attention to Grotonweather.com and other weather media sources for frequent updates on the dangerous weather. The weather during these situations may rapidly change. It is strongly recommended that you become a follower of Grotonweather.com on Facebook and/or Twitter for these situations, as updates are frequently issued there. (Click here for our Facebook and Twitter pages). Often times (but not always due to other time restraints), special Grotonweather features are available during these times, including Weather Chats, Videos, safety tips and special maps.

The bottom line is this: as a meteorologist, I personally feel a responsibility to keep you informed and safe during severe weather. The absolute worst thing I can imagine is having a weather related fatality under my watch. The Grotonweather.com Alert Mode is meant to help prevent that from ever becoming a reality. If you see an Alert Mode has been issued, stay aware and "keep checking back for updates!"

2/24 PM Forecast Discussion

My apologies for having to post this here. The SUNY Oswego campus network has somehow decided to block all Grotonweather.com traffic from its network. I have managed to update most of the forecast as normal, but things such as the confidence forecast and uploading snow maps are impossible. Hopefully this will be fixed soon....in the mean time, we have a snow storm on our hands!

Forecast Discussion
A rapidly strengthening storm system over Arkansas will lift north and east, crossing across Pennsylvania tomorrow morning. The models are more or less in agreement with one another now, and they all keep the warm air and rain to the south. Despite this, I am still a tiny bit weary of the possibility of rain for Tompkins and southern Cortland County, as the rain/snow line will only be 30-50 miles to the south. I do have enough confidence to go with all snow now though. As I said this morning, since this storm is probably going to end up all snow, we are going to get it good. Below the discussion is the snow map I made for this storm. Most of the Grotonweather.com area is in the 7-14" range. Honestly though, I would not be at all surprised to see 16" or even 18" somewhere in that pink area. The snow will move in after midnight tonight and really become heavy for the morning hours tomorrow. By afternoon, the snow should begin to taper off. However, the winds will be on the increase, blowing all that fresh snow around. Significant blowing and drifting is likely tomorrow. I would likely be going into SNOW ALERT MODE if I had access to my files. Saturday and Sunday will each feature a shot at a few flurries, but nothing significant. Another storm will be in the works for Monday, but this one should remain all rain with the low tracking well to our west.


Storm total snowfall through Friday evening.
