The best dynamics for an isolated tornado to pop up is in the moderate risk area indicated by the red shaded counties which include Mifflin, Juniata, Perry, Snyder and Northumberland. The rest of the area may still experience strong to severe storms.
SEVERE THUNDERSTORM WATCH in effect until 8pm for parts of the area. With the warm and humid conditions and a cold front advancing conditions are favorable for strong to severe storms. Concern will be for damaging winds, hail and even isolated tornadoes.
THIS EVENING: Strong to severe storms are likely this evening after 3pm and until around 10pm as a cold front advances across the area. Keep an eye to the sky if you are planning on be out but take cover immediately if threatening weather approaches. You will not want to mess around with the severe storms. Temps will fall from through the 80s to the 70s.
OVERNIGHT: Still muggy and warm with lows in the upper 60s to low 70s. There could be isolated showers overnight.
TOMORROW: Another cold front comes in tomorrow and this one will usher in drier air for Thursday. Highs will still warm to the mid 80s and it will feel humid to start but the humidity should improve later in the evening.
OUTLOOK: High pressure builds in for Thursday and Friday bringing a couple of dry days with highs in the low to mid 80s. Looks like our string of nice and rain free weekends comes to an end although it won’t be a washout by any means. Saturday looks to be mostly dry with only an isolated storm threat. Highs will warm to the mid 80s but Sunday with the next front approaching, shower and storm chances go up and so does the humidity. Highs will be warmer too in the upper 80s. Monday it looks like the storm threat continues until the front passes. It will be a warm and humid start to the week with highs near 90.
