Weather Dudes

Welcome to WEATHERDUDES.COM... We are currently focused on weather and climate of the Hampton Roads area of Virginia and the East Coast, as well as other significant national and global weather events that occur. The intent of this site is not to be just another weather website with five day forecasts featuring happy suns and sad clouds It is to provide various interesting and personalized features, which provide the visitor with a view of the weather from a different perspective.
Currently we have:
Dave's Weather Discussion Page, providing an insight to the local weather conditions and patterns, and the reasons behind the weather.
Tropical Weather, A collection of tropical storm and hurricane resources.
Recent Weather, Weather conditions for the past 10 days for the mid-Atlantic area.
Weather Glossary, Providing weather definitions from A to Z.
Links to Weather Sites, providing a growing collection of links to weather sites.
Weather Facts, A collection of interesting weather facts.
We will be adding more features on a regular basis. Feel free to look around, and let us know what you think. Check back often for new content...

Predicting Snow in the Hampton Roads Area... Why is it so challenging?

It is never easy for meteorologists in our area when the rain/snow line is going to be close by. I am not trying to make excuses for meteorologists here locally, but I want to try to explain why they face a difficult and challenging forecast with situations when the rain/snow line is going to close by. Problem 1) The Ocean: We live next to a body of water that is in the 40s normally during the winter months. If the wind blows from the ocean, the temperature cannot be cold enough at the surface to support snow right along the coast. Further out to sea to our southeast is the warm Gulf Stream waters. A southeasterly wind blowing from water that is in the 60ís eliminates any chance of snow for our area. However, a northerly wind or even a north-northeasterly wind can be cold enough to support snow as long as the air to our north is very cold to start with. Problem 2): The Ocean again: The ocean provides storms their energy and moisture, so as a low pressure area moves towards the coast, it can intensify very rapidly, and sometimes surpass what forecasters were predicting. This rapid intensification can result in heavy precipitation. This brings us to Problem 3) When precipitation falls heavily, it can bring colder temperatures to the surface and change the rain to snow. Low pressure areas that are intensifying rapidly cool the upper air behind them, so storms intensifying to our east cool the atmosphere to their west (over our area) which also can change the rain to snow. There are other variables that affect our weather such as dry slots, but these are the major things that have to be considered locally when issuing a forecast for snow. Note that Norfolk averages just under ten inches of snow a year.
