.DISCUSSION...
High pressure centered over the Great Lakes will slowly drift
eastward through the middle of the week. An upper-level
disturbance may bring a few showers to the Allegheny Highlands
this afternoon, but most of the area will remain dry with below
normal temperatures through at early Wednesday. The next frontal
system may bring higher rain chances to the entire area Thursday
into Friday. This front will reinforce the below normal
temperatures.
