> How Weather Works

> "Heat is the mechanism that causes weather," says Dave Barrons,
chief

> cold air masses moving across the continent form fronts that
influence
> our daily weather patterns. A weather front is simply the boundary
> formed when one air mass pushes against another. A cold front is
cold
> air pushing against relatively warm air and a warm front is
relatively
> warm air pushing against a cool air mass."

> Cold fronts often follow storms and are normally made up of air
that's

be
> associated with clear skies and air temperatures that are several
> degrees cooler than the air mass they are replacing.
>
> The air in a cold front is also somewhat more dense than the air
> around it. Weathermen refer to this condition as a high-pressure
ridge
> and these masses of air tend to settle towards the ground.
>
> Warm fronts are made up of air that's warmer and lighter than
> surrounding air. Because the air is warmer and lighter it rises into
> the atmosphere. Typically the barometric pressure is lower than
> experienced with a cold front.
>
> Unlike cold fronts, warm fronts often form a vortex or spinning of
> air. In extreme cases when the barometric pressure drops sharply, a
> tornado can develop.
>
> Low-pressure air centers are storms waiting to happen. When a cold
> front collides with a warm front, the mixing of air can generate
> weather that ranges from unpleasant to downright threatening.
>
> How Weather Influences Walleye Activity
>
> Like all fish, walleyes are influenced by weather conditions. The
very
> best conditions for walleye fishing are periods of extended stable
> fair weather. Any time the weather stays the same for several days,
> the fishing is likely to improve each day.
>
> Ideal conditions include warm or seasonally mild temperatures and
some
> sunshine, but several days of cloud cover can also yield good
fishing
> so long as the daily temperatures and wind conditions remain about
the
> same.
>
> Extended periods of hot and calm weather often cause walleyes to
bite
> like there will be no tomorrow. Sometimes called the dog days of
> summer, most anglers associate hot and sticky days with poor
fishing.
> Actually, the warm weather may be uncomfortable for anglers, but the
> fishing action can be outstanding.

> The worst conditions for finding cooperative walleyes are severe
cold
> fronts that follow low-pressure center storms. Fishing success just
> prior to the storm front can often be excellent. Those folks who
have
> bird feeders understand that just before a storm arrives, feeding at
> the feeders is brisk. Wildlife can sense approaching foul weather,
and
> they often feed heavily just prior to the storm. Walleyes are no
> exception.
>
> Once the storm passes, the cold front that follows can spell lousy
> fishing for several days. Typically these cold fronts feature
bright,
> clear skies and a dramatic temperature drop that not only makes the
> air temperature uncomfortable but can lower water temperatures, as
> well. High barometric pressure takes over and walleyes that were
> active just a day or two prior seem to disappear.
