Detailed Summary:

The medium-range period will begin with a frontal boundary gradually pushing southward across the 
northern Plains and into the central Plains.  Showers and thunderstorms appear to be most active 
from the 4th of July into Friday morning across the northern Plains where a heavy rain area is 
indicated.  The rain could be locally heavy in this general area on Saturday as well as to the west 
over the northern High Plains on July 4th but they appear to be too small to specify on the hazards 
chart.

Over much of the eastern U.S., there will be a good chance of scattered showers and thunderstorms 
through next Monday to the south of the frontal boundary.  The rainfall amounts are not expected to 
be heavy for much of the East Coast through next Monday, except over parts of the Carolinas on the 
4th of July, although isolated heavy downpours cannot be ruled out.

Excessive heat is forecast to extend one more day across southern Georgia into northern Florida on 
the 4th of July.  Thereafter, a broad upper-level trough is forecast to develop along the East 
Coast with the surface cold front gradually edging to the south.  This will keep the heat 
suppressed across the Mid-Atlantic and into the Southeast through next Monday.

For Alaska, an anomalous upper-level high is forecast to dominate a large portion of Alaska into 
early next week.  Temperatures are forecast to reach record high levels across southern Alaska, and 
they are expected to spread further inland and westward toward the west coast during the weekend.  
The anomalous warmth will also be accompanied with an increasing risk of wildfires.  Check the GIS 
hazards map for the areas of excessive heat and fire weather risk.
