As many of you know, many sites are available on the internet offering weather information. Below are a few sites that might be useful. Before making any decisions, please verify the date/time stamps on the site. Always check to ensure that data viewed is the most recent available, if possible.

Texas A & M University Warnings

The Texas A & M University offers a very good graphical weather weather warning system. I find them very reliable for current watch and warning information. The *only* flaw with the site is if two watches are in effect for the same area... it is hard to tell overlaying watches apart. Click on the image to go to their site.

SPC Day 1 Outlook

Five times a day, the Storm Prediction Center (SPC) will issue the Day1 Outlook, predicting where severe storms are likely to exist. They use three alert levels -- SLIGHT (in Green), MODERATE (in Yellow) and HIGH (in Red). Below, the computer models from 1AM Milwaukee time and 3PM Milwaukee time are shown.

SPC Meso Discussions

As needed, the SPC will follow up the outlooks with a Mesoscale discussion. If there are any MDs issued, the areas they affect will be circled in Red. Please click on the graphic to go to the SPC Meso site, and read up on the latest information.

Satellite Images

Pictures of the clouds provide the big picture of a weather system. Meteorologists use these images to see where the moisture is coming from, and obtain clues if storms will have enough fuel to survive.

Radar Images

Radar images make real-time images of where the rain is currently falling, and can determine what areas will experience the wrath of the storm in the near future. Note that radar sites cannot observe storm data directly above them, so it pays to view neighboring radar sites!

Please click on the below radar image to view local area radars.

Surface Temperature Chart

Temperature Charts display the surface temperature, allowing us to view where frontal boundaries exist, as well as hint what kind of precipitation may be falling, and general wind direction.

Surface Dewpoint Chart

Dew Point Charts display the moisture levels in the air, and in the summer time, become a valuable resource to see how much energy is in the air. The higher the dew point, the more muggy and tropical the airmass will be.
