As the remains of Katrina race across upstate New York today they are running into a cold front. More than that the circulation of the tropical storm whipping the southern part of the cold front in our direction, pushing all this lovely steamy weather upon us.
Most people like sunny weather but today sunny is not such a good idea. The sun is heating the lower atmosphere, making it more unstable and increasing the likelihood of severe weather later this afternoon. Nothing's showing up on the radar just yet, but there's a better than even chance we'll see some torrential downpours before the day is over. Thunderstorms, high winds and an isolated tornado are possible.
After the rain moves through tonight, we will be in for a stretch of pleasant weather. It may be a bit warm tomorrow and Friday with highs near 90, but the Labor Day weekend is looking sweeeet. Sunny, highs around 80, lows in the mid-60s through the middle of next week.





please let there be rain. It's so hot, I want to take my pants off. Hey maybe the subway flasher was just suffering from heat exhaustion
How'd Katrina get from Louisiana to Canada in a day and a half? I guess it's for the best (less time lingering over our red state friends), but it sure seems mighty quick to me.
Well, it's not your run-of-the-mill weather system. It was a hurricane. Hurricanes move fast, even if they slow down a bit once they hit land. Did you see the winds it produced?
There's two speeds associated with hurricanes. The rotational speed about the eye of the storm is the 75mph+ wind that are always reported and reflect the strength of the storm.
There's also a translational speed, or the speed at which the entire storm moves. This speed depends on the upper level winds, which are slight in the tropics but very strong in mid-latitudes. Once Katrina moved far enough north it gets picked up by the jet stream and zips along.
i call bullshit on weather predictions! in the last month it has rained two days, weather forecasters have predicted over 15 days of rain in that time! enough! i refuse to bring an umbrella with me again!
