   ...SYNOPSIS...
   A MID-LEVEL SHORTWAVE TROUGH AND ASSOCIATED CYCLONE WILL ADVANCE EWD
   ACROSS PORTIONS OF THE NWRN CONUS...WITH PERIPHERAL FLOW AT THE SRN
   EXTENT OF THE TROUGH RESPONSIBLE FOR THE EWD/NEWD ADVANCE OF A
   CYCLONE FROM THE SW STATES TO THE ROCKIES. THE LATTER CYCLONE IS
   EXPECTED TO DEVOLVE INTO AN OPEN-WAVE TROUGH AND WEAKEN. A
   DOWNSTREAM MID-LEVEL RIDGE WILL COVER PORTIONS OF THE ERN PLAINS TO
   THE GREAT LAKES REGION AND SE STATES...WHILE CYCLONIC FLOW PERSISTS
   ACROSS THE NORTHEAST. DRY THUNDERSTORMS WILL BE UNLIKELY ACROSS THE
   CONUS.

   ...PORTIONS OF W-CNTRL NV AND ADJACENT EXTREME ERN CA...
   A BAND OF ENHANCED MID-LEVEL FLOW ACCOMPANYING THE AFOREMENTIONED
   TROUGH WILL SUPPORT WLY SFC WINDS AROUND 15 MPH WITH LOCALLY HIGHER
   GUSTS DURING PEAK HEATING. RH VALUES ARE EXPECTED TO FALL INTO THE
   20S DURING THE AFTERNOON...WITH RH VALUES LOCALLY/BRIEFLY FALLING
   INTO THE UPPER TEENS -- AIDED BY DOWNSLOPE-FLOW-ENHANCED
   WARMING/DRYING IN THE LEE OF THE SIERRA MOUNTAINS. AS A
   RESULT...MARGINALLY/LOCALIZED/BRIEF ELEVATED FIRE WEATHER CONDITIONS
   MAY ENSUE. HOWEVER...WITHOUT STRONGER LOW-LEVEL FLOW AND/OR A DRIER
   AIR MASS...CONFIDENCE IN ENHANCED FIRE-WEATHER CONDITIONS IS TOO LOW
   FOR THE INCLUSION OF HIGHLIGHTS.
