Detailed Summary:

Pattern change for most of the CONUS will be underway as of Friday 4 October as a strong cold front 
will usher in cooler temperatures for the eastern states. One last day of well above normal 
temperatures on Friday will be confined to the Southeast as readings reach into the middle and 
upper 90s. In the West, temperatures will moderate by the start of the period as a frontal system 
moves out of the Rockies. That system will bring a chance of locally heavy rain on Saturday to the 
Corn Belt back to the Central Plains as a warm front lifts northeastward. 

After Saturday, the front will continue eastward and bring modest to locally heavy rain to some 
areas, but timing/placement uncertainty precluded a focused hazard area just yet. Best chance for 
heavier rain on Sun/Mon will be over the Ohio Valley into the Appalachians but these areas have 
been fairly dry as of late anyway. 

In Alaska, an incoming area of low pressure is forecast to track through the Bering Strait Fri/Sat 
which could lead to gusty winds, but possibly below hazards criteria. Attendant cold front will 
push through the Gulf with triple point low redevelopment which will increase chances for heavy 
precipitation there. Precipitation should generally remain rain along the coast and snow in higher 
elevations. Another system is forecast to move out of eastern Russia (with embedded remnants of 
tropical storm Mitag) toward the Bering Strait again by next Tuesday, bringing some wind and rain 
to the coastal areas, but left off the outlook chart for now given the detail uncertainty.
