   ..COHEN.. 03/27/2015

   .PREV DISCUSSION... /ISSUED 0319 AM CDT FRI MAR 27 2015/

   ...SYNOPSIS...
   AMPLIFIED UPPER PATTERN...CHARACTERIZED BY AN ERN CONUS TROUGH AND A
   WRN CONUS RIDGE...WILL PERSIST THROUGHOUT THE PERIOD WHILE GRADUALLY
   SHIFTING EWD. WRN CONUS RIDGE WILL DAMPEN SOMEWHAT AS A SHORTWAVE
   TROUGH MOVES THROUGH THE PACIFIC NW AND INTO THE NRN ROCKIES DURING
   THE SECOND HALF OF THE PERIOD. SHORTWAVE TROUGH EMBEDDED WITHIN THE
   LARGER TROUGH WILL MOVE ACROSS THE SOUTHEAST STATES AND
   CAROLINAS...ACTING TO SLIGHTLY DEEPEN THE LARGER TROUGH. AT THE
   SURFACE...HIGH PRESSURE INITIALLY POSITIONED FROM THE MID MO VALLEY
   NEWD THROUGH THE UPPER MS VALLEY WILL SHIFT EWD/SEWD TOWARDS THE
   GREAT LAKES/MID MS VALLEY WHILE LEE TROUGHING DEVELOPS FROM THE NRN
   ROCKIES SEWD INTO THE CNTRL PLAINS. ENHANCED PRESSURE GRADIENT
   BETWEEN THESE TWO SURFACE FEATURES WILL RESULT IN SOME GUSTY NW
   WINDS ACROSS PORTIONS OF CNTRL AND NRN HIGH PLAINS. A COLD FRONT IS
   EXPECTED TO MOVE OFF THE CAROLINA COAST AND THROUGH MUCH OF THE FL
   PENINSULA. 

   ...ERN WY...SW SD...NEB PANHANDLE...NE CO...
   PREVIOUSLY DISCUSSED ENHANCED SURFACE PRESSURE GRADIENT COMBINED
   WITH STRONG NWLY MID/UPPER LEVEL FLOW WILL HELP SUPPORT SUSTAINED
   NWLY SURFACE WINDS AROUND 20-25 MPH FOR SEVERAL HOURS DURING THE
   AFTERNOON. WIND GUSTS WILL LIKELY TOP 30 MPH AT TIMES. RH VALUES ARE
   GENERALLY EXPECTED TO STAY ABOVE 20 PERCENT...PRECLUDING CRITICAL
   CONDITIONS BUT MIN RH VALUES NEAR 25 PERCENT WILL STILL BE LOW
   ENOUGH TO RESULT IN ELEVATED FIRE WEATHER CONDITIONS. RH VALUES MAY
   DROP BELOW 20 PERCENT IN AREAS WHERE DOWNSLOPE EFFECTS ARE
   MAXIMIZED...RESULTING IN LOCALLY CRITICAL CONDITIONS.
   HOWEVER...UNCERTAINTY REGARDING CRITICAL RH VALUES IS HIGH AND THE
   SPATIAL EXTENT WILL BE LIMITED EVEN IF CRITICAL RH VALUES ARE
   REALIZED. AS SUCH...A CRITICAL AREA WILL NOT BE DELINEATED WITH THIS
   FORECAST.
