... Several rounds of wintry precipitation will be possible this week with much colder weather anticipated by the beginning of next week.
NEAR TERM /UNTIL 9 AM WEDNESDAY MORNING/... Light precipitation associated with a weak shortwave will overspread the region tonight. Saturated low levels below freezing, combined with cloud top temperatures nearing ice crystal growth, and weak lift will produce areas of patchy freezing drizzle and light snow. Any precipitation that occurs will not be widespread and is not expected to accumulate, thus an advisory has not been issued at this time. Precipitation chances will linger through midday Wednesday once the aforementioned shortwave exits the region. High temperatures Wednesday will be near average.
SHORT TERM /9 AM WEDNESDAY MORNING THROUGH FRIDAY/... After a brief dry period Wednesday night into Thursday morning, another low pressure system will move from Missouri through eastern Ohio into New York. This will bring another round of precipitation to all locations. With the low tracking north of the region, this should pull the rain/snow line into south central portions of the area. Highest snow totals are expected around the I 80 corridor and in the ridges, where 2-4 inches are possible. The bulk of the precipitation will have moved east by Friday, with some rain/snow persisting east of Pittsburgh on Friday. Temperatures will be 5-10 degrees below normal Wednesday night, then warm back towards climatology Thursday into Friday.
LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... While Friday night should be dry, the next round of wintry precipitation moves into the region late Friday night into Saturday and Sunday. It appears that this low may track farther to the south, allowing less warmer air to get pulled into the region and keeping more precipitation as snow. There is still much uncertainty to the overall track of the storm and therefore the specifics for any snowfall totals. The earliest headlines /winter storm watch/ for the area won't be issued until Thursday, so there are still several more model runs to get a better handle on the track of the storm.
Precipitation will change to all snow by Sunday morning and temperatures should fall all through Sunday into Sunday night, allowing temperatures to drop into the single digits everywhere both Sunday night and Monday night. This could result in a need for wind chill headlines Monday morning. Highs on Monday will only rise into the teens, but temperatures will rise back into the mid 20s to mid 30s by Tuesday.
