This image was taken on Tuesday, February 1st at 4:15 PM.  When you click on the image, you should be able to see narrow lake effect streamers over the western end of Lake Ontario.  These snowbands are actually a downwind extension of activity off Georgian Bay.  For those of you who have been following our lake effect weather, you know that the upwind lakes can play an important role in the location and intensity of snowbands that form downwind (on northwest flow) across our region.  This image is pretty dark, especially to the right or eastern end of the image. Why?  hint: sunset in Buffalo is at 5:28 PM. 

IR Satellite

This IR image was taken at night, around 5:00 AM.  When you click on this image you will see that it is much more difficult to see snowbands with IR imagery, for a couple of reasons.  First, the resolution is not as good, the IR image is 2km and the visible is 1km.  In addition though, the cloud top temperatures in the IR image are often very similar to the background temperature of the snow covered ground, so there is very little contrast to the image.

These radar images show the snowband at various stages of their life cycle.  When you click on the left image you will see the activity that continued to drift eastward and settle over Rochester as the night progressed.  Later on, the right hand image shows the last stages of a band that might have been an extension of the Georgian bay activity just before it dissipated.
