Thursday Evening Weather Update:
Football fans are in store for a great night for some football at FirstEnergy Stadium as the Browns play the Lions at 7:30 p.m. Skies will be mostly clear with temperatures in the low to mid 70s at the start of the game.
I think by the end of the game, we'll start seeing high clouds move into the Cleveland area, but conditions will remain dry through 11 p.m.
Some high school football games kick off the season tonight. Here's the latest forecast from the Channel 3 Weather Center:
On the latest weather analysis from the National Weather Service office in Cleveland, a weak cold front will approach northwestern Ohio later tonight and will move southeast through the area by late Friday morning. Scattered showers and isolated thunderstorms will accompany the front.
High pressure will then temporarily build in before a series of weak disturbances brings along precipitation chances Saturday night through Monday.
Here's your short term forecast from the Channel 3 Weather team:
TONIGHT | Clouds increase with rain chance by morning. A bit more humid. | Mid 60s
FRIDAY | Morning rain chances, otherwise partly cloudy. | Upper 70s
Hurricane Dorian Update:
All meteorological eyes are on Hurricane Dorian this evening as the category one storm is expected to go as high a category four storm when it hits Florida late Sunday or early Monday.
Some of the computer models, then show the storm moving partly across Florida, turning north and then hugging the East Coast for several days. This would be a worse case scenario that could be flooding and storm surge to large areas.
As of the 5 p.m. National Hurricane Center update, Dorian is 330 miles east of the southeastern Bahamas moving to the northwest at 13 m.p.h. Maximum sustained winds are 85 m.p.h.
The forecast continues to show the storm moving through the Bahamas and hitting the east coast of Florida. By 2 p.m. Tuesay, the center of the hurricane will be over the Central Florida peninsula as a category one storm.

Weather Instruments: The Anemometer
Today, let's talk about the device that we use to measure the wind.
Forecasters use an anemometer to take measurements of how fast the wind is moving at a given location. This instrument is a a common weather station tool whose name is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in meteorology, according to Wikipedia.
The most common type of anemometer uses cups that capture the wind as blows past the device and causes the cups to spin.
This motion is sensed by a magnetic or optical sensor in the device that converts the signal to a feet per minute measurement. This is, in turn, further calculated as miles per hour that you see featured in our daily weather reports.
The inventor of the anemometer is Leon Battista Alberti who built the first device in 1450 as a mechnical unit. Alberti was an Italian Renaissance humanist author, artist, architect, poet, priest, linguist, philosopher and cryptographer.
Later in 1664, Robert Hooke who was an English philosopher, architect and polymath, re-invented the anemometer and is often mistakenly cited as the original inventor.
The other part of wind measurement often associated with the anemometer is the wind vane. The piece is often attached on or near at the wind cups. The "tail" of the vane catches the wind and spins the pointer into the direction the wind is headed.
