Pennsylvania will have an extended cold and dry spell through this weekend and extending for much of next week.  Most regions will see highs consistently failing to get out of the 30s, with only the southeastern areas possibly seeing some lower 40s.  Some clouds will linger this weekend, but the early part of next week will be mainly sunny.  Temperatures will also warm up slightly by the midweek, but they will still be below average for this time of year.
