# # # **1. Northeast Clipper: Final Impacts & Snowfall Totals**
The quick-moving low pressure system is finally making its exit off the Northeast coast. Snow is tapering off from west to east, but slick travel conditions remain across parts of **Pennsylvania, New York, and New England** this morning.
* **Snowfall Wrap-Up:** Most areas saw a general widespread accumulation of **1 to 3 inches**, typical for these fast-movers. However, higher elevations and parts of the interior Northeast (particularly the Adirondacks and Green/White Mountains) likely picked up localized amounts of **3 to 6 inches** where the bands persisted longer.
* **Current Impacts:** Lingering flurries and snow showers will continue for the next few hours in New England before the system pulls away completely. Watch for black ice as temperatures plummet.

# # # **2. The Brutal Cold: Arctic Air Arrives**
Right on the heels of the snow, a strong **High Pressure System** (currently centered over the Plains) is building in. This is ushering in the coldest air of the season so far.
* **The Drop:** As the low departs, it is dragging down frigid Arctic air on north-northwest winds. Expect temperatures to crash throughout the day.
* **Wind Chills:** Gusty winds combined with the temperature drop will push wind chill values dangerously low by tonight.

# # # **3. Big Picture: Next 12-Hour Forecast**
Looking at the national map for the next 12 hours (Valid through Friday Evening):
* **West Coast (Pacific Northwest):** A new frontal system is slamming into the coast. Expect **heavy rain and mountain snow** to continue across Washington and Oregon (indicated by the deep moisture plumes on the map).
* **Central US:** Dominated by that massive High Pressure system. Skies will be clearing, but it will remain very cold and dry.
* **The South:** A stationary boundary is draped along the Gulf Coast, keeping rain chances alive for parts of Texas and the Lower Mississippi Valley, but the deep cold air is mostly staying just to the north of this boundary.
