   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1033 AM CST FRI MAR 06 2015

   VALID 061700Z - 071200Z

   ...N-CNTRL KS AND EXTREME SRN NE...
   16Z OBSERVATIONS REVEALED TEMPERATURES IN THE 40S ACROSS MUCH OF THE
   REGION. THE QUICK WARM-UP IS EXPECTED TO CONTINUE AS THE SHALLOW
   BOUNDARY LAYER INVERSION ERODES WITH A DRY AIRMASS AND DOWNSLOPE
   EFFECTS HELPING TO PUSH HIGHS INTO THE 60S. ANTECEDENT DRY AIRMASS
   IS ALSO EXPECTED TO SUPPORT RH VALUES BELOW 20 PERCENT THIS
   AFTERNOON. WITH A SURFACE HIGH CENTERED OVER THE SRN PLAINS AND LOW
   PRESSURE ASSOCIATED WITH A FAST-MOVING SHORTWAVE TROUGH MOVING INTO
   THE NRN PLAINS...SURFACE PRESSURE GRADIENT OVER THE REGION WILL
   TIGHTEN SOMEWHAT WITH MODEST MID/UPPER SUPPORT FOR SOME GUSTY WINDS
   ALSO IN PLACE. WIND SPEEDS ARE STILL EXPECTED TO REMAIN GENERALLY
   AROUND 15 MPH WITH OCCASIONAL GUSTS OVER 20 MPH. THESE CONDITIONS
   ARE CONSISTENT WITH AN ELEVATED FIRE WEATHER THREAT AND THE ELEVATED
   AREA INTRODUCED WITH PREVIOUS FORECAST WILL BE LEFT IN PLACE WITH
   ONLY MINOR CHANGES.

   ..MOSIER.. 03/06/2015

   .PREV DISCUSSION... /ISSUED 0308 AM CST FRI MAR 06 2015/

   ...SYNOPSIS...
   BROAD CYCLONIC FLOW ALOFT WILL BE MAINTAINED GENERALLY EAST OF THE
   ROCKIES TODAY...WHILE RIDGING REMAINS SITUATED ALONG MOST OF THE
   WEST COAST. MULTIPLE SHORTWAVES EMBEDDED IN THE CYCLONIC FLOW WILL
   PROGRESS TOWARDS THE MIDWEST AND EAST COAST...WITH THE MOST
   SIGNIFICANT OF THESE TRANSLATING OFFSHORE BY THE END OF THE PERIOD.
   AT THE SFC...HIGH PRESSURE WILL STRETCH FROM THE SRN PLAINS TO NEW
   ENGLAND...WHILE PASSAGE OF THE AFOREMENTIONED SHORTWAVES RESULTS IN
   A PAIR OF FRONTAL BOUNDARIES PUSHING EAST ACROSS THE NRN PLAINS AND
   MIDWEST. ADDITIONALLY...GREAT BASIN HIGH PRESSURE WILL COMBINE WITH
   AN INVERTED TROUGH ALONG THE CA COAST TO PRODUCE E/NELY FLOW ACROSS
   SRN CA. WHILE DRYING WILL BE ENHANCED BY LOCAL TERRAIN EFFECTS IN
   THE MOUNTAINS AND FOOTHILLS...A MARGINAL PRESSURE GRADIENT AND
   GENERALLY UNRECEPTIVE FUELS WILL PRECLUDE ANY WIDESPREAD FIRE WX
   THREAT.

   ...N-CNTRL KS AND EXTREME SRN NE...
   A DRY AIR MASS CURRENTLY IN PLACE ACROSS THE CNTRL PLAINS /EVIDENCED
   BY 00Z SOUNDING PWAT VALUES OF 0.1-0.2 INCHES/ WILL PROMOTE LOW RH
   VALUES DURING THE DAY AS DOWNSLOPE WLY FLOW AND DIURNAL MIXING
   ENSUE. RH VALUES WILL LIKELY APPROACH 20 PERCENT DURING THE
   AFTERNOON HOURS /WITH SOME SPOTS IN THE 15-20 PERCENT RANGE/...AS
   TEMPS RISE INTO THE LOWER-MID 60S. WHILE WINDS WILL NOT BE
   PARTICULARLY STRONG AS THE LOW-LEVEL PRES GRADIENT APPEARS
   MARGINAL...DEEP MIXING AIDED BY THE AFOREMENTIONED DOWNSLOPE
   COMPONENT WILL PROMOTE WINDS TO AROUND 15 MPH /WITH OCCASIONAL
   HIGHER GUSTS/. CONSIDERING THE LACK OF PCPN OVER THE LAST 1-2
   WEEKS...DRY FINE FUELS WILL BE SUPPORTIVE OF ENHANCED FIRE SPREAD.
   AS SUCH...AN ELEVATED DELINEATION HAS BEEN INTRODUCED.
