Currently a warm front is pushing thru the western half of PA with a low pressure area back over eastern Iowa. This warm front is attached to a low pressure moving across southern Canada and is part of a complex frontal situation. A cold front also extends from the low pressure in Canada and this cold front trails back to another area of low pressure over Wyoming!
As the warm front lifts to the North the cold front will begin to drop southward and should be approaching western PA by about 2 PM in the afternoon. A couple different waves or impulses of low pressure will develop along this front .
By 8 PM this front will have cleared western PA and western NY.
This front will be the focus of severe weather potential. Across portions of SE NY and into portions of eastern PA and NE PA it could be possible that in addition to the winds and hail potential that even an isolated tornado could occur. This will be possible because of the low level shear that will be in place in that region and the timing of the low pressure area. So that is something to keep in the back of your mind as we go thru the day tomorrow!
Stay tuned for more information should it become needed!
