SEVERE STORMS POSSIBLE: Overcast skies and breezy conditions remain the norm throughout Thursday afternoon and evening. For any trick-or-treaters this Halloween evening, it’s not looking good. Winds will gust between 25-35MPH out of the south, bringing in some warm air ahead of thunderstorms late in the afternoon and throughout the evening. There is a risk these storms could be severe. On a scale of 1-to-5, we’re at a 3 for the entire area. Our main concern is gusty winds up to 60MPH and heavy rain that could lead to flash flooding.
There is a very low threat for a brief, isolated, spin-up tornado – but by no means is that a primary concern. After a few spotty showers in the early afternoon, the main line begins to push into our western counties by the evening rush home.
The line moves west-to-east, affecting the Harrisburg and York areas around 7PM, if not a little before. The storms continue to push through with the bulk of the activity wrapping up in our eastern counties by 11PM. Temperatures rapidly decline overnight as a gusty west-northwesterly wind replaces the rain. Morning lows in the low-to-mid 40s will be the norm with winds easily gusting up to 30MPH. Additional rainfall totals of 1-2″ will be the norm on top of the rain that fell yesterday.
DRYING OUT FRIDAY: As we progress throughout Friday, the winds slowly calm down by late afternoon and early evening. However, even with a bit of sunshine, we stay much cooler with highs only in the low-to-mid 50s. A few lake effect snow showers will be possible northwest of our area, but we remain unaffected. Temperatures drop into the 30s heading into Saturday morning with a chilly start to the weekend.
MUCH COOLER WEEKEND: Temperatures don’t leave the low-to-mid 50s again Saturday afternoon with partly-to-mostly sunny skies. Don’t forget to set those clocks back an hour Sunday morning! Temperatures Sunday afternoon struggle to reach the upper-40s as breezy conditions return with a dry system passing overhead. Morning lows near freezing start off Sunday and also for Monday morning as we head into next week.
