Another potent frontal system pushes into the Panhandle for early next week. Confidence is increasing as the forecast models have come into better alignment that widespread rainfall totals of up to around 2 to 4 inches will be in store for Monday into Wednesday, with higher amounts at higher elevations. Freezing levels will still be high, around 6,000 ft, allowing for some additional melt around glacial systems. Due to the heavier rainfall and elevated snow levels in combination with already saturated soils from recent appreciable rainfall, rises in area rivers and streams are expected. Stay tuned for updates on this next system through the weekend or visit weather.gov/juneau.
