...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.
