headaches, headaches in children, migraine headaches, sinus headaches, tension headaches, visual disturbances.
A primary differential in your case is a tension headache or a migraine headache. Weather as a trigger for patients with migraines is relatively inconclusive.There are some studies however that shows migraine to be a a trigger for some people but most results are not really significant.
In your case, this may not be something very urgent.You had your previous bouts of headaches relieved through correction of your apnea and bruxism ( teeth grinding).Also, this headache seems to have a genetic factor involved.
Get yourself a consult with a neurologist fo a primary assessment.A CT scan may be able to help rule out any possible intracranial involvement.
Protect yourself from the cold weather.Wear a cap, cover your ears and wear scarves if necessary.This may help prevent the headaches.
