Washington – “WINTER-LIKE CONDITIONS POSSIBLE LATE THIS WEEK”
– National Weather Service
“Saturday night through Monday: This will be the coldest part of the next seven days. It`s possible that the cold will set new temperature records. The NBM guidance indicates high spread, which is not surprising, but single digit low temperatures are not out of the question for Sunday and Monday mornings if there is snow on the ground. High temperatures look to be in the 30s! If these temperatures verify, it will be as if we skipped past the rest of fall and jumped into winter. /SVH”
Thursday to Friday morning: Decent cold advection behind the front ushers in temperatures 8 to 14 degrees below normal for much of the region. This will be just the beginning of the cold as temperatures will just continue to drop heading into next weekend.
As the next system approaches on Friday, cloud cover and precipitation chances move in from the northwest corner of our forecast area Friday morning. RC
…WINTER-LIKE CONDITIONS POSSIBLE LATE THIS WEEK…
Friday to Monday: A robust system is projected to drop in from the north this period, bringing with it the potential for winter precipitation and very cold temperatures for this time of year.
