Weather

A weak disturbance is bringing isolated showers and wet thunderstorms over N ID and Western MT today in PSAs 3-6 and a few will develop later in PSAs 8-9. Otherwise warm dry conditions will continue today and tomorrow with above average temps. and low RHs...to continue the fuels drying process. Only isolated convection is likely tomorrow over Central MT. On Thursday and Thursday night though a low pressure trough/surface cold front will move across the region. Scattered showers and isolated wet thunderstorms are expected wit the greatest coverage in central/eastern MT into ND. Along with some cooling and higher RHs...which will continue into Friday. 

Long-range models continue to show strong ridging re-building in from the west over the region this coming weekend...and through all next week. Thus...an extended warm/dry period will resume over the region...with above average temps. and fairly low RHs. 

Fuels/Fire Potential

The potential for the development of large fires is low. However...all indices have showed drying across PSAs  3, 4, 5, and 6. Fuels in these areas are not quite expected to become critically dry this week..but there could be an increase in IA. 

Resources

Resources are adequate.
