Spot Forecast for Nelchina Glacier Fire...SOA DOF
National Weather Service Anchorage AK
738 PM AKDT Sun Jun 29 2025

Forecast is based on forecast start time of 0900 AKDT on June 30.
.DISCUSSION...

A shortwave trough moving over the Copper Basin will initially
support widespread light rain and dense cloud cover during the
morning on Monday, but rain should taper off to widely scattered
showers by Monday afternoon as the trough begins to weaken. Winds
will generally be around 10 mph or less out of the southwest
through Monday night.

By Tuesday, an upper level ridge of high pressure will build in
from the north, resulting in clearing skies and slightly warmer
temperatures and lower minimum RH values during the afternoon.
Winds will also turn more southerly as a coastal pressure gradient
develops along the northern Gulf Coast. While predominant winds
are currently expected to stay no higher than 10 to 15 mph,
expect some potential for higher gusts coming off of the glacier
during the afternoon on Tuesday.
