Thread: Barometric Pressure "forecast" on the Web

Try MSN.weather, it will give you barometer reading and if it is rising or falling plus your forecast.

This is one I like (change to your city), no BP but pretty good wind info.

I don't think Atmospheric Pressure can be forcasted accurately. NOAA has a good hour-by-hour historical page that shows progress of BP:http://www.weather.gov/data/obhistory/KGWO.html

Hey Brian P:

You can go to http://weather.noaa.gov/, enter your state under "United States Weather" and then select reporting stations around your area to see what the current and past 24-hour weather conditions including barometric pressure. Then you can go to http://image.weather.com/images/maps...wx_600x405.jpg,
http://image.weather.com/images/maps...st_720x486.jpg,
http://image.weather.com/images/maps...st_720x486.jpg and
http://image.weather.com/images/maps...st_720x486.jpg to see how the highs and lows are predicted to move in the next 24 to 36-hours. If a high is expected to move over your area then you'll have rising and/or high pressure and visa-versa. By counting the isobars between the highs and lows you an get an idea of how much difference the pressure is between them and how drastic your weather may change in the next 24-hours.

The surface maps are pretty reliable for predicting rainfall in your area too. Sometimes they forget to change the day at the top of the map - especially on weekends. Right now (5:00am Monday) for example they have "Monday" on the top of the "Morning Forecast" but is obviously Tuesday morning's prediction.

Bingo on what Jerry said. Not only do you become a grand crappie angler but you get to be a pretty good weatherman too. Not only do the forecast charts give you an indication of pressure but wind also (synonymous of each other). And we all know we love to fish in the wind. The closer the isobars are the stronger the wind. I have fond memories of my grandpa looking at his barometer every time before we left the cabin to go fishing.

One last comment on weather. The weatherman's prediction on rain is our enemy. A 40% chance of rain merely means there's a 60% chance it won't. Plus, you don't know what part of the state that 40% chance is actually for. So, another way of looking at it is there's always a 100% chance of rain where it is raining and a 0% chance where it is not. Check the radar, go fishing, enjoy and don't take chances when it comes to lightning. After two close calls in the past 3 years I don't hide nor am I ashamed of my genuine respect for it.

It's a bit spendy (~$90) but there's a product out that advertises that it will provide [solunar table] best fishing times, and also provide a current and ~4 hr. advance fishing forecast based on current barometer and it's forecasted barometric pressure trend.
Here's a URL to their site. Also has a weather alarm feature, that could be handy for those times when you've relaxed a bit to much while enjoying the fishing...and didn't notice the storms approaching...

Thanks so much for taking time to reply. Good info here. Maybe it will help me put a few more in the boat. And yes, I respect the lightning (want to learn that lesson the easy way) and also the wind. It can be more dangerous than we give credit sometimes. Thanks again to all.

Thanks a bunch Jerry for the weather lesson. Sure can make it safer by looking before heading out. Living real close to a big lake that seems to draw bad weather can make it exciting sometimes. I've had it sneak up on me a couple times so this might help some. Sometimes we forget to watch the horizon when they are biting. I really appreciate the wealth of information that you and Darryl provide on here. Ferdi aka Fred:D
