This is the only way to go about your time as an undergraduate and if you can do this effectively (take on internships and any opportunity that presents itself) you will become marketable. Based on my experience, the people who put that extra time in with unpaid internships have been able to at least land part time jobs right out of college or at least get interviews. Thinking about it now, there are 4-5 of us in that category of part time/full time jobs and we all sacrificed time and money working at the NWS, private companies, or broadcast stations while at school.
A degree in meteorology on your resume says nothing. That along side a minor, an internship or two, a research project, some minor forecasting experience, and some kind of leadership position at school says you are motivated, enthusiastic, and can handle alot at once which is what every employer looks for. Right off the bat they dont have to ask if that person fits the criteria we are looking for, they know it. That should at least get you an interview.
This is just a perspective from a recent graduate... cant speak much for what will lie ahead. Hope this helps some of the young guys.. BE INVOLVED WHILE AT COLLEGE and do not waste your time. Enjoy it too, it really should be the best time of your life.
