Northern Alaska forecast discussion 
National Weather Service Fairbanks Alaska 
209 am akdt Friday may 24 2013 


Discussion... 
models in decent agreement through about 60 hours with only minor 
position differences. Upper level ridge is weak over the interior 
as it stretches westward to the West Coast today. Thermal trough 
is weak within the ridge until late afternoon when the trough 
begins to strengthen. The 500h wavers back and forth a few 
decameters over the course of the next 120 hours and beyond. 


None of the models are excited about any convective potential 
through at least Sat. Beginning sun...500h remain nearly constant 
while lower level temperatures drastically increase which within 
the thermal trough would likely be enough of a trigger to at least 
spawn a few showers in the far eastern interior sun and Monday. 


Temperatures will continue to be on The Incline over the next 
several days. The climb in temperatures will create above normal 
temperatures for much of northern Alaska through at least the 
first part of the week. This will aid in the snow melt and could 
exacerbate an already delicate break up on interior rivers. A 
moderately strong cold front is advertised to sweep down over the 
Northwest Arctic coast by Tuesday according to the GFS while the European model (ecmwf) 
shows no cold front anywhere near Alaska. But both models do show 
a decent thermal trough over the eastern interior. 


&& 


Fire weather...a general increase in lower level moisture over 
much of northern Alaska will continue to keep relative humidity values above 30 
percent for many location except for the far eastern 
interior...particularly along the alcan border. 




&& 


Hydrology...flooding or high potential of flooding along the 
Yukon river south and west of Fort Yukon will continue for the 
next few days.
