Wipers... argggg!!

Hi!

I just cant figure this one out! Ive had a 97 civic for 3 years now and I 
have the same problem every winter: The wipers dont touch the part of the 
windshield that is in front of my face!!!

Its like as soon as it gets really cold, the wiper lifts off of the 
windshield right exactly at my eye level. OR maybe the windshield somehow 
collapses down a tiny bit at that spot. I dont know, but its really 
annoying and dangerous! 

It doesnt make a difference if Im moving forward or sitting still.

I just put new winter teflon blades on 2 weeks ago. They work perfectly 
when the temp is above 0 but this morning, just like every winter, as soon 
as the temp dropped below zero the problem happened again!!!

ANY ideas would be much appreciated!!

Thanks!!!

Scott
