   ...Synopsis...
   An upper low will pivot into CA and the Great Basin D2/Thursday
   bringing cloud cover, cooler temperatures and precipitation back
   into the Southwestern U.S. during the day, reaching the Northern
   Rockies by Thursday night. This will alleviate a broader fire
   weather threat across much the West. An upper-level ridge situated
   over the Plains accompanied by an expansive surface high pressure
   across the eastern U.S. will persist through Thursday. Light
   northerly flow will shunt Gulf moisture southward, leading to
   appreciably low RH values of 15-20% during the day over the lower MS
   River Valley and portions of the Southeast where fuels remain dry.
   However, weak boundary layer flow will limit afternoon wind speeds
   to less than 10 mph, mitigating significant fire weather concerns.

   Valid 221200Z - 281200Z

   Upper-level high pressure will persist across the middle of the
   country, while a cutoff low slowly drifts just off the Eastern
   Seaboard through Day 3/Thursday. This pattern will continue
   near-normal temperatures amid dry conditions over much of the
   Southeast US. Vegetation in this area will become increasingly
   vulnerable to burning, especially across the southern Appalachian
   Mountains and the lower Mississippi River Valley, where ERCs are
   forecast to reach the 90-95th percentiles. However, generally weak
   winds will limit the overall fire threat. Forecast models suggest
   the upper-level ridge will shift toward the East Coast early next
   week, briefly introducing at least slightly warmer-than-normal
   conditions alongside ongoing dryness.

   A strong upper-level low will push onshore CA on Day 3/Thursday and
   progress toward the Great Basin, eventually approaching the Great
   Plains by Day 6/Sunday. Expect resulting colder air and widespread
   precipitation across a large portion of the Intermountain region,
   portions of the Sierras, and the coastal CA mountains where fuels
   have been persistently dry. Moving forward in time to next week,
   forecast certainty decreases. However, recent trends in forecast
   guidance indicate that an upper-level ridge is likely to return to
   the Intermountain West by mid-to-late next week with embedded
   shortwave troughs.
