Detailed Summary:

High pressure over much of the CONUS will keep conditions fairly calm for several days. Numerous 
locations along the Missouri and Mississippi Rivers, and their tributaries, are expected to 
maintain major to record flooding through at least Tuesday. A cold front traveling south will 
become quasi-stationary near the southern tip of Florida through Wednesday, with a wave of low 
pressure forecast to develop along the boundary just off of the southern tip of Florida on 
Wednesday. Moisture will pool along this boundary and will aid in producing heavy rain over 
portions of southern Florida Tuesday into Wednesday. 

In Alaska, a series of storms will move into the Gulf of Alaska through Thursday with a stream of 
deep moisture directed toward the southern coast that will start to wane while producing heavy 
precipitation from the Alaska Peninsula to Prince William Sound and into parts of the Alaska 
Panhandle on into Tuesday. High wind is also possible from Kodiak Island to Prince William Sound 
into parts of the Alaska Panhandle on Monday associated with the strong pressure gradient 
associated with the multiple storms moving into the area.
