   ...Eastern U.S....
   An upper-level trough and associated surface low will translate
   eastward from the Great Plains on Day 3/Wednesday to the eastern
   Seaboard through the weekend Day 6-7/Saturday-Sunday. Widespread
   rainfall is expected across much of the eastern U.S. as the trough
   and associated cold front interact with a broad moisture plume
   through the weekend. In addition to rainfall, accelerating green-up
   should mitigate fire spread potential into early next week (Days
   7-8/Sunday-Monday).

   ...Southwest...
   A short wave-trough with an associated mid-level jet will move into
   the Southern High Plains for Day 3/Wednesday. This will overrun a
   dry/well-mixed boundary layer supporting low relative humidity and
   gusty west winds across southeastern New Mexico into far West Texas.
   A subtle mid-level wave moving into the Southwest along with
   antecedent mid-level moisture could bring isolated dry thunderstorms
   to portions of northern Arizona and New Mexico on Day 5. However,
   some uncertainty exists with evolution of expected precipitation
   primarily north of the Interstate 40 corridor from Days
   2-4/Tuesday-Thursday. This could prevent higher lightning ignition
   efficiency so no isolated dry thunderstorms probabilities were
   introduced. A larger scale upper-level trough and strong mid-level
   jet could bring broad fire weather threat to areas of the Southwest
   as early as Day 5/Saturday lasting into early next week for Day
   8/Monday. 40 percent critical probabilities were maintained across
   southeastern Arizona/southwestern New Mexico for Days
   5-6/Friday-Saturday. Some timing uncertainty exists in eastward
   ejection of upper-trough and associated dynamics into the Southern
   Plains so extension of Critical probabilities into Day 6 was
   withheld for portions of the Southwest for Day 7-8/Sunday-Monday.
