Detailed Summary:

**Due to technical issues, the drought monitor information for the WPC Day 3-7 hazards outlook is 
unavailable**

An upper level low over the Southwest U.S. to start the medium range period will shift eastward 
towards the Southern Plains. While the heavy rain threat associated with this system is mostly in 
the short range, some lingering mountain snows will be possible across parts Four Corners region 
and Southern Rockies on Thursday, though amounts and coverage are marginal to include an area on 
the hazards map. As this system ejects eastward, heavy rainfall is expected to develop, with 
guidance continuing to suggest the potential for a couple inches of rain from Arkansas/northern 
Louisiana eastward to the Southern Appalachians/southwest Mid-Atlantic on Thursday and Friday. 

In Alaska, a deep cyclone over the western Mainland and multiple waves of low pressure moving into 
the Gulf will bring rounds of heavy rain/mountain snows across especially the higher terrain of the 
southern mainland coast and much of the Panhandle. High winds/waves are also likely associated with 
this system, though intensity may be below criteria for inclusion on the hazards chart for today.
