DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0352 AM CDT WED SEP 02 2015

VALID 031200Z - 041200Z

...SYNOPSIS...
THE UPPER PATTERN ON D2/THU SHOULD REMAIN SIMILAR TO D1/WED...WITH
AN UPPER TROUGH CONTINUING TO AMPLIFY OVER THE NWRN CONUS...AND
DOWNSTREAM RIDGING CONTINUING OVER MUCH OF THE CNTRL/ERN CONUS. AT
THE SFC...A COLD FRONT SHOULD CONTINUE EWD OVER THE NRN PLAINS...
BUT WILL PROBABLY MAKE ONLY A SLOW SEWD PROGRESSION ACROSS THE NRN
GREAT BASIN AND NRN/CNTRL ROCKIES WITH HIGH PRESSURE FORECAST TO
REMAIN CENTERED OVER WRN CO. ENHANCED LOW TO MID-LEVEL WINDS OVER
PORTIONS OF THE GREAT BASIN AND NRN/CNTRL ROCKIES MAY HELP ELEVATE
FIRE WEATHER CONCERNS ACROSS SOME OF THIS REGION THU AFTERNOON AND
EVENING.

...PORTIONS OF THE GREAT BASIN AND NRN/CNTRL ROCKIES...
ELEVATED FIRE WEATHER CONDITIONS APPEAR PROBABLE ON D2/THU FROM
CNTRL NV NEWD INTO NWRN UT AND PORTIONS OF WRN/CNTRL WY. ACROSS
THESE STATES...ENHANCED MID-LEVEL WINDS AROUND 25-40 KT SHOULD
ENCOURAGE SFC WINDS OF 15-25 MPH BY THU AFTERNOON WITH DIURNAL
MIXING OF THE BOUNDARY LAYER. AS TEMPERATURES GENERALLY WARM INTO
THE MID 70S TO MID 80S...RH VALUES SHOULD LOWER TO 15-20 PERCENT
ACROSS THIS REGION. CURRENT MODEL FORECASTS OF BOTH SUSTAINED WINDS
AND SFC RH VALUES SUGGEST LOCALLY CRITICAL FIRE WEATHER CONDITIONS
MAY OCCUR ACROSS PORTIONS OF CNTRL/ERN NV FOR A COUPLE OF HOURS THU
AFTERNOON...AND A CRITICAL DESIGNATION MAY BECOME NECESSARY IN LATER
UPDATES IF CONFIDENCE INCREASES IN RH VALUES REMAINING BELOW 15
PERCENT FOR A SUFFICIENT LENGTH OF TIME.
