RE: Rye Brook, NY | D/A: June 1 & 2, 2006 | Case No: 0112356673

Dear Mr. Smith,

As you requested, I have reviewed the weather conditions for the Rye Brook, NY area on June 1 & 2, 2006. A summary and table for your review follows. The summary and table below have been derived using the best available weather data and are an estimate of the conditions that occurred in the Rye Brook, NY area for the period stated above.

In order to determine with a reasonable degree of meteorological and scientific certainty, the weather conditions in the Rye Brook, NY area, I examined official surface weather observations, monthly COOP data, public information statements, Doppler Radar images and sunrise – sunset data. All of the data was accessed from the online web pages of the National Climatic Data Center, the Upton, NY National Weather Service Forecast Office and the US Naval Observatory Astronomical Applications Department. An explanation of these data sources is listed on the following page.

Surface Weather Observations are usually taken at airports on a continuous basis at one report per hour minimum. These observations usually contain a wealth of data pertaining to hourly temperature, cloudiness, visibility, wind direction and speed in addition to precipitation amounts and the depth of snow and ice on the ground.

In order to estimate the weather conditions in the Rye Brook, NY area on June 1 & 2, 2006, the following station was examined:

Climatological records contain a summary of the past 24 hours and are usually taken once a day by private weather observers, universities, FAA Facilities and National Weather Service offices. Though occasional errors are found in these Climatological observations, most are extremely reliable. They must, however, only be utilized as a supplement to the highly detailed airport observations.

In order to estimate the weather conditions in the Rye Brook, NY area on June 1 & 2, 2006, the following reports were examined:

The National Weather Service Forecast Office out of Upton, NY issues Public Information Statements during and after a storm that has been affecting their region. The reports come from highway departments, cooperative observers, skywarn spotters and media.

There are 158 operational Doppler Radar sites across the United States. Each Radar site has a range of about 143 - 288 miles depending on the mode of operation. Numerous products are derived using the Doppler Radar. For this report, I examined Base Reflectivity Images and Storm Total Precipitation. Base Reflectivity images depict the intensity and location of precipitation, while Storm Total Precipitation shows the total amount of precipitation that fell over an area during a certain period of time. These images were derived from the radar site KOKX, which is located in Suffolk County Long Island, NY

June 1^st, 2006 was warm and humid with evening thunderstorms. During the pre-dawn hours, the sky became cloudy with areas of dense fog. The temperature held in the mid 60’s. Clouds and fog gave way to some hazy sunshine by late morning, and these intervals of hazy sunshine persisted into the afternoon hours. The temperature warmed to an afternoon high in the mid 80’s. Showers and a thunderstorm overspread the Rye Brook, NY area between 7 and 8 PM and tapered off shortly after 11 PM. Thereafter, the sky was cloudy and the temperature leveled off near 70 degrees towards Midnight. The 24 hour rainfall total was approximately 0.50 inches. No watches, warnings or advisories were issued for the Rye Brook, NY area on this day.

June 2^nd, 2006 featured more rain. Scattered showers returned to the Rye Brook, NY area from 4 AM – 7 AM. Thereafter, the rain temporarily ended and the weather remained overcast. Periods of rain returned to the area between 12 and 1 PM and then continued on and off into June 3^rd. The heaviest rain stayed south of the area.
