   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0334 AM CDT SUN APR 19 2015

   VALID 201200Z - 211200Z

   ...NO CRITICAL AREAS...

   ...SYNOPSIS...
   CYCLONIC FLOW WILL EXIST OVER THE ERN TWO-THIRDS OF THE CONUS ON
   D2/MON...WITH A CLOSED MID/UPPER LOW POSITIONED OVER WRN ONTARIO.
   MEANWHILE...A WEAK REX-BLOCK PATTERN WILL BE POSITIONED ALONG THE
   WEST COAST...WITH RIDGING OVER THE PAC NW AND TROUGHING NEAR SRN CA.

   THIS PATTERN WILL FEATURE RELATIVELY LIGHT WINDS THROUGHOUT THE
   TROPOSPHERIC COLUMN TO THE WEST OF THE ROCKIES. HOWEVER...FARTHER
   EAST...DEEP NW FLOW WILL BE PRESENT OVER THE NRN/CNTRL PLAINS.
   DIURNAL MIXING WILL WORK IN CONCERT WITH THIS STRONG FLOW TO YIELD
   SUSTAINED WINDS AROUND 20-25 MPH DURING THE DAY. ADDITIONALLY...A
   DRY AIR MASS /CHARACTERIZED BY PWAT VALUES AROUND 0.2-0.3 IN/ WILL
   LIKELY COMBINE WITH THE AFOREMENTIONED MIXING TO PROMOTE MIN RH
   VALUES BELOW 25 PERCENT. A NARROW WINDOW FOR ELEVATED FIRE-WX
   CONCERNS MAY EXIST OVER SERN SD/FAR NERN NE...WHERE RECENT PCPN HAS
   BEEN RELATIVELY LIGHT. HOWEVER...MARGINAL TEMPS IN THE 50S...AND
   SOME LINGERING UNCERTAINTY REGARDING PCPN PRIOR TO THE
   PERIOD...PRECLUDE A DELINEATION WITH THIS FORECAST. HOWEVER...IF
   LITTLE ADDITIONAL RAINFALL OCCURS AND CONFIDENCE IN WARMER TEMPS
   INCREASES...AN ELEVATED DELINEATION MAY BECOME NECESSARY.
