... After morning snow, cloudy and cold conditions will remain for the rest of the day. A return to seasonal conditions is expected for the weekend before cold air returns mid-week next week.
NEAR TERM /UNTIL 6 PM THIS EVENING/... Bulk of the snow has returned to the Pittsburgh area for a quick shot of additional accumulation this morning. PoPs were updated through the next few hours. Snow will wane rapidly with the departure of the lower- and upper-level support. Previous discussion follows...
Bulk of the snow has moved off to the east as low pressure moves offshore. Have dropped the non-ridge winter weather advisory on time, but a period of generally light snow showers will continue in post-frontal northwest flow for a few hours. These should diminish later this morning as inversion heights drop and moisture wanes. The ridge areas will continue with the advisory for now with the upslope help, but even here, activity should diminish by noon. Main change was to up PoPs west of the ridges for lingering snow showers, otherwise mainly minor changes were made.
Plenty of clouds remain today in the strong cold air advection and temperatures will be well below normal.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/... Clouds will linger overnight.
Weak shortwave trough will approach the area late Friday, returning the risk for snow showers. Temperatures remain well below normal on Friday.
LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... Trough will quickly swing through Friday night and snow showers will linger into Saturday.
Slow height rises aloft begin Saturday afternoon, bringing and end to the snow shower activity and allowing for warmer air to overspread the region.
Flow goes zonal over our area by Sunday as our trough lifts out and energy digs into the southwest U.S. This will result in continued temperature moderation towards more seasonal levels. The next system arrives on Sunday and will be mainly a rain producer from the southern branch of the jet stream. The pattern could remain unsettle thereafter with weak waves in the west- southwest flow aloft, with perhaps another cool down by the middle of next week.
