   .PREV DISCUSSION... /ISSUED 0304 AM CDT SUN MAY 24 2015/

   ...SYNOPSIS...
   A LARGE CLOSED UPPER LOW WITH EMBEDDED SHORTWAVE CIRCULATIONS IS
   CENTERED OVER THE CNTRL ROCKIES EARLY THIS MORNING. THIS LOW WILL
   MOVE NEWD TOWARDS THE NRN PLAINS AND UPPER MIDWEST BY EARLY MON
   MORNING. AN UPPER RIDGE OVER THE OH/TN VALLEY REGION AND SERN U.S.
   SHOULD SHIFT SLIGHTLY EWD THROUGH THE PERIOD. AT THE SFC...A LOW
   PRESSURE AREA OVER NERN OK SHOULD REDEVELOP NEWD TO THE VICINITY OF
   THE UPPER MS VALLEY REGION THROUGH THIS EVENING AS A SHORTWAVE
   TROUGH WITHIN THE LARGER WRN U.S. UPPER LOW CIRCULATION ALSO MOVES
   NEWD WITH TIME. A SEPARATE SFC LOW SHOULD REMAIN OVER NERN NM AND
   THE WRN TX/OK PANHANDLES THIS AFTERNOON. A COMPOSITE COLD
   FRONT/DRYLINE FEATURE ATTENDANT TO THE SFC LOW OVER THE SRN HIGH
   PLAINS WILL BE LOCATED ACROSS ERN NM/FAR W TX. DRY POST-FRONTAL
   CONDITIONS WILL CONTINUE ACROSS MUCH OF THE NERN U.S.

   ...PORTIONS OF NEW ENGLAND...
   SIMILAR TO YESTERDAY...A DRY LOW-LEVEL AIRMASS REMAINS IN PLACE
   ACROSS MUCH OF NEW ENGLAND TODAY AS UPPER RIDGING APPROACHES THE
   REGION FROM THE W...AND AS WLY SFC WINDS ON THE NRN PERIPHERY OF
   HIGH PRESSURE CENTERED OVER THE WRN ATLANTIC CONTINUE. AS
   TEMPERATURES WARM INTO THE UPPER 60S AND 70S ACROSS MUCH OF THE
   REGION...RH VALUES SHOULD FALL INTO THE 20-30 PERCENT RANGE FOR A
   FEW HOURS THIS AFTERNOON. 

   THE STRONGEST MIDLEVEL WINDS ROUNDING THE APEX OF THE UPPER RIDGE
   ARE FORECAST TO REMAIN MOSTLY TO THE N OF LOWERED RH AREAS.
   HOWEVER...BASED ON LATEST SHORT-TERM GUIDANCE AND FORECAST
   SOUNDINGS...A MODEST ENHANCEMENT TO THE SFC WINDS SHOULD OCCUR FOR
   PORTIONS OF ERN NY...MA...NRN CT/RI...SRN VT/NH...AND FAR SRN MAINE
   THIS AFTERNOON. THE COMBINATION OF SUSTAINED WINDS OF 10-15
   MPH...WITH SOME HIGHER GUSTS...ALONG WITH SUFFICIENTLY REDUCED RH IN
   THE PRESENCE OF DRY FINE FUELS SHOULD RESULT IN ELEVATED FIRE
   WEATHER CONDITIONS ACROSS THIS REGION FOR A FEW HOURS THIS
   AFTERNOON. THEREFORE...AN ELEVATED AREA HAS BEEN INTRODUCED FOR A
   PORTION OF NEW ENGLAND.

   ...PORTIONS OF ERN NM AND W TX...
   A MARGINAL COMBINATION OF GUSTY WINDS WITH LOWERED RH VALUES WILL
   OCCUR BEHIND A COLD FRONT/DRYLINE ACROSS PORTIONS OF ERN NM AND W TX
   THIS AFTERNOON. HOWEVER...DUE TO SUSTAINED WINDS FORECAST TO EXCEED
   15 MPH ON JUST A BRIEF/ISOLATED BASIS AND GENERALLY UNRECEPTIVE
   FUELS...NO ELEVATED AREA HAS BEEN INCLUDED AT THIS TIME.
