Weather

A cold front moving through the Interior from the north today will bring near freezing morning temperatures to the eastern portions of the state, and dry air to the west. The strong northeasterly winds that are accompanying that front have given rise to Red Flag Warnings for much of central and western Interior Alaska.

Meanwhile, the ridge that has been in place over western and southern Alaska is retreating, but will bring another day or warmth and sunshine to the Panhandle, South Central, and much of western Alaska, particularly the inland areas. In addition, Southwest is expecting wet thunderstorms today, which could give rise to some ignitions in that area.

The long wave trough will move over the state tomorrow, and keep a more transient, cooler regime in place through Wednesday. After that, southerly flow will bring a return of warmer temperatures again by the end of the week. With the trough remaining in place over western Alaska, this will allow some weak ridging to move in from Canada into eastern Alaska, warming and drying by next weekend.

Fuels/Fire Potential

Windy conditions will produce elevated ISIs across the Interior and into northwest AK.  Fires that find favorable fine fuels will spread rapidly under sunny conditions.
Fine fuels are very dry south of the AK range, but lighter winds will mitigate spread for fires that get started.
Fires in Delta area reported Rank 4 fire behavior and deep burning. This reinforces levels of DMC and FWI and what they mean for spruce.  Warmer weather will bring a return of extreme conditions.

Resources

Alaska is at PL2. We have a number of Overhead from Northwest Compact (WA, OR, and ID), 2 Next Gen Tankers and 2 Booster loads of jumpers.
