Weather

The front that moved through the state yesterday, sparking thunderstorms across much of the central and eastern Interior, is moving into Canada today, and will give rise to more wet thunderstorms in Fortymile Country along the ALCAN border this afternoon. Behind the front, clearing will gradually occur and conditions will begin to dry out again.
Ridging will build in from northwest Alaska southward, bringing sunshine which will significantly dry fuels in western and southern Alaska. Inland areas of Southwest, South Central, and Copper River Basin are likely to see the biggest effects, with humidities dipping into the upper teens in some areas. Southeast Alaska is also expecting a drying trend through the weekend.
Early next week, a long wave trough pattern over mainland AK brings cold air from the north into central Alaska, and has the potential to drop morning temperatures below freezing on Tuesday and Wednesday mornings north of the Alaska Range. This pattern will hold through mid-week, then a return to warmer weather is in store.

Fuels/Fire Potential

Warming and drying in southern AK is bringing FFMCs into the low 90s. With nice weekend weather in the forecast, expect human ignitions. Winds are generally light, but dry fine fuels are driving ISIs into double digits in parts of Copper River Basin and on the Kenai Peninsula, indicating rapid spread.

Despite some rainfall yesterday, much of the Interior remains dry and burnable, though full greenup is approaching.  

Duff Moisture Codes (DMCs) for many reporting locations in the east and central Interior are now over 80, suggesting more fuel is available and likelihood of higher intensity burning. While greenness maps show that much of the Interior is at least a little ahead of normal for greenup, hardwood leaf litter is holding fire under these conditions. This outlines the more complex situation for fuel availability at this time of year. Under warm, dry, and sunny conditions, fires will burn aggressively, especially in fire prone spruce and moss fuels.  Grasses and tundra may need more favorable wind conditions as they reach peak green.
