...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF S-CNTRL/SERN ID...FAR
NERN NV...

...SYNOPSIS...
AN UPPER-LEVEL TROUGH WILL AMPLIFY FROM SWRN CANADA ACROSS THE
PACIFIC NW. A BELT OF MODERATELY STRONG W/SWLY MID-LEVEL FLOW WILL
BECOME ESTABLISHED FROM NRN CA ACROSS THE NRN GREAT BASIN BY SAT
AFTERNOON.

...PORTIONS OF S-CNTRL/SERN ID...FAR NERN NV...
MARGINAL TO LOW-END CRITICAL CONDITIONS SHOULD DEVELOP SAT AFTERNOON
AS W/SWLY MID-LEVEL FLOW STRENGTHENS ATOP A DEEPLY MIXED BOUNDARY
LAYER. SUSTAINED SURFACE WINDS SHOULD REACH 15 TO 25 MPH...AS RH
VALUES BECOME RATHER LOW /BETWEEN 5 AND 10 PERCENT/. THE ERN EXTENT
OF THE THREAT IN SERN ID WILL BE SUBDUED BY RECENT ABOVE-NORMAL
RAINFALL.

...LEE OF THE NRN SIERRAS IN FAR NERN CA/NWRN NV...
LOCALIZED CRITICAL CONDITIONS MAY DEVELOP ALONG THE LEE OF THE NRN
SIERRAS. ALTHOUGH THE MAGNITUDE OF MID-LEVEL FLOW WILL BE SIMILAR TO
THE AFOREMENTIONED CRITICAL AREA...MODEL FORECAST SOUNDINGS INDICATE
SLIGHTLY WARMER MID-LEVEL TEMPERATURES RESULTING IN LOWER MIXING
HEIGHTS. THIS SHOULD HELP HOLD SUSTAINED SURFACE SPEEDS TO AROUND 12
TO 20 MPH. NEVERTHELESS...THIS WILL BE JUXTAPOSED WITH VERY LOW RH
VALUES OF 3 TO 8 PERCENT.
