DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0214 AM CDT TUE JUL 28 2015

VALID 281200Z - 291200Z

...SYNOPSIS...
SEASONABLY STRONG MID/UPPER SYSTEM PRESENTLY OVER THE NORTHERN
ROCKIES WILL CONTINUE TO MOVE NORTHEASTWARD INTO SOUTHERN MANITOBA
BY THE END OF THE D1/TUE PERIOD.  AS THIS OCCURS...STRONGER
MID-LEVEL FLOW WILL MOVE EAST INTO THE NORTHERN PLAINS AND UPPER
MISSISSIPPI VALLEY AND A 1028-MB SURFACE HIGH WILL SETTLE INTO THE
NORTHERN GREAT BASIN.  A SHORTWAVE RIDGE WILL MOVE EAST ACROSS THE
GREAT LAKES DURING THE PERIOD...WHILE A STRONGER UPPER RIDGE WILL
REMAIN ANCHORED ACROSS THE SOUTHERN PLAINS.

...SOUTHERN WYOMING INTO WESTERN NEBRASKA...
ALTHOUGH MID-LEVEL FLOW WILL GRADUALLY WEAKEN DURING THE FORECAST
PERIOD...WESTERLY FLOW WILL PERSIST IN THE AREA...WITH 15-MPH WINDS
EXPECTED DURING THE AFTERNOON.  THE AIRMASS THAT HAS SETTLED INTO
THIS REGION IS SOMEWHAT COOLER THAN IN PREVIOUS DAYS /I.E. 70S F
AFTERNOON SURFACE TEMPERATURES/ BUT REMAINS DRY WITH 7-15 PERCENT RH
EXPECTED FOR SEVERAL HOURS DURING THE AFTERNOON AND EARLY EVENING.
GIVEN DRY FUELS AND FUEL BEDS IN THE REGION...AN ELEVATED FIRE
WEATHER DELINEATION HAS BEEN MAINTAINED PRIMARILY ACROSS
SOUTHERN/EASTERN WYOMING AND WESTERN NEBRASKA.  ALTHOUGH A FEW
ISOLATED AREAS IN WESTERN NEBRASKA RECEIVED WETTING RAINS FROM
THUNDERSTORMS MONDAY EVENING...A FIRE WEATHER THREAT WILL EXIST
WHERE FUELS REMAINED RAIN-FREE.

...NORTHERN/NORTH CENTRAL CALIFORNIA INTO SOUTHWESTERN OREGON...
AS HIGH PRESSURE SETTLES INTO THE NORTHERN PORTIONS OF THE GREAT
BASIN...LOCALLY STRONG OFFSHORE FLOW WILL DEVELOP ESPECIALLY IN
HIGHER ELEVATIONS DURING EARLY MORNING HOURS.  FUELS ARE
DRY...ESPECIALLY GIVEN THE PERSISTENT DROUGHT THE REGION HAS
EXPERIENCED OVER THE PAST SEVERAL MONTHS.  RH VALUES WILL REMAIN
LOW...WITH POOR OVERNIGHT RECOVERIES EXPECTED AND VALUES DROPPING AS
LOW AS 5 PERCENT DURING THE DAY.  GIVEN THE AFOREMENTIONED
FACTORS...AN ELEVATED FIRE WEATHER THREAT AREA HAS BEEN MAINTAINED
FOR THIS FORECAST.
