regarding severe weather June 1, 2007 discusses the lake breeze interaction as the storm enters the Chicago area.
I chased in and around Bay City and Bad Axe MI a few years back and the Storms got tornadic as they hit the last 10 to 20 miles before the lake.
One poster, I forget who exactly had a signature that was something like.
"disable the cook county (IL) convective deflector"
I have watched storms in OH get a little more active as they interact in a glancing direction with the Lake Breeze.
Florida seems to get some Ocean breeze CU activity.
I grew up about 1 mile from Lake Erie and the weather was often strikingly ominous in appearance as clouds and storms would come in with very low bases off of the Lake.
All of the above threads and references seem to have something to do with Lake Breeze and it's effects.
So now that I am interested in Severe Storms, how do I predict forecast or otherwise understand Lake Breeze Severe weather interaction ?
My current mode is to just prepare for things to change as a storm interacts with the Lake breeze. Some get more severe some die out.
Needless to say just knowing that things might change is not the most helpful tidbit of information.
So if someone could answer the following questions it would be great.
What is it about the lake breeze that affects storms ?
Does the "lake front" generate some much needed spin ?
Does the humidity bring the cloud bases lower ?
Does the front provide some lift as a focus for initiation ?
Supposing the lake Breeze "front" lies straight East to West. Is it more likely to enhance a storm with motion roughly parallel or roughly perpendicular to the "lake breeze front" ?
Are there some guidelines for predicting the effects ?
How do I find the Lake Breeze? Sometimes it is obvious on Satellite. Sometimes it is obvious from reported observations. Most of the time it is so subtle that it is hard to locate.
Any pointers to papers or research on this topic would also be helpful.
