A very busy day weatherwise as severe storms continue to ravage the Ohio and Tennessee Valleys with the Storm Prediction Center marking this as a "High Risk" day for tornados, high winds and hail. Thankfully, here at home, we are expected to get some rain, but nothing near as severe as what they're getting to the west. Some places that were hit earlier this week are getting hit again, such as around Harrisburg, IL, however that town has not been directly reported hit yet today. This situation reminds me of the April 27th. One round of severe hit fairly early, priming the atmosphere for the stronger, more severe event to follow later in the afternoon.
Here in the Delaware Valley, we can consider a scattered thunderstorm as "tranquil" compared to other areas. The precipitation will start to filter in around 6pm, from southwest to northeast with the heavier rain moving in around 8pm to 9pm. The possibility of a scattered rumble of thunder and torrential downpour exists overnight but by daybreak tomorrow, just a steady rain will persist. Lows tonight in the mid-40s and highs tomorrow near 60. Winds will be from the south tonight, shifting to the southwest by tomorrow.
Rain should start to taper off by mid to late afternoon tomorrow, however scattered showers will linger into the overnight. Most of your Saturday night plans shouldn't be canceled, just bring an umbrella. Winds will also start to pick up as this large low pressure system starts to move off to the north and east.
Sunday, as high pressure tries to move in, it will be breezy and much cooler. By Monday, flurries and the occasional "fizzard" might be possible as temperatures struggle to make it into the 40 with a weak upper level disturbance quickly move through. Otherwise, sun and clouds will prevail. No accumulation is expected in the Philadelphia Metro, with a coating possible as you get closer to Allentown. Tuesday skies will gradually clear and temperatures return to normal. Wednesday and Thursday, skies will be mostly sunny with temperatures in the mid to upper 50's - edging close to 60 in some spots Thursday and Friday.
Friday night, the next system moves in and medium-range outlooks suggest another chance of rain and snow, with temperatures falling behind this storm as well. Looks like the March lion was just a little late.
