DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0350 AM CDT SAT JUL 26 2014

VALID 261200Z - 271200Z

...SYNOPSIS...
AN UPPER-LEVEL LOW WILL BEGIN MOVING SEWD TODAY FROM SRN
SASKATCHEWAN TOWARD THE UPPER MS VALLEY AFTER CRESTING AN
UPPER-LEVEL RIDGE CENTERED OVER THE SRN ROCKIES/HIGH PLAINS.
MEANWHILE...THE RIDGE WILL AMPLIFY OVER THE PACIFIC NORTHWEST. AT
THE SURFACE...LOW PRESSURE WILL MOVE TOWARD THE GREAT LAKES REGION
WHILE HIGH PRESSURE BUILDS IN OVER THE NRN ROCKIES.

...SWRN WY...
AS STRONGER FLOW ALOFT DEPARTS THE AREA TODAY...THIS SHOULD BE LAST
DAY IN A SERIES OF DRY AND BREEZY CONDITIONS OVER SWRN WY.  AS THE
BOUNDARY LAYER GROWS THROUGHOUT THE AFTERNOON...VERTICAL MIXING WILL
RESULT IN SUSTAINED WLY SURFACE WINDS AOA 15 MPH AND RH VALUES AOB
15 PERCENT. GIVEN THE DRY FUELS ACROSS THE REGION...ELEVATED FIRE
WEATHER CONDITIONS ARE LIKELY.

...SERN MT...NWRN SD...
AN INCREASING SURFACE PRESSURE GRADIENT ACROSS THE REGION AND
ENHANCED NWLY FLOW ALOFT WILL LEAD TO SUSTAINED NWLY SURFACE WIND
SPEEDS AROUND 20 MPH AS THE BOUNDARY LAYER DEEPENS IN THE AFTERNOON.
ALTHOUGH RH VALUES WILL BE MARGINAL /AOB 25 PERCENT/...THE POTENTIAL
FOR GUSTY WINDS /AOA 30 MPH/ WILL ELEVATE FIRE WEATHER
CONCERNS...ESPECIALLY FOR LOCATIONS THAT HAVE NOT RECEIVED WETTING
RAINS OVER THE PAST COUPLE OF DAYS.
