Hi! I'm from Erie and the forecast for the weekend goes something like this:
Friday: Partly Cloudy, high 71
Saturday: Partly Cloudy, high 70
Sunday: Chance of showers, high 70
The lows are in the mid 50's.
Now, you know the weather changes quickly here so you may want to check out the local forecast by using the following link to WSEE 35
