   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   POWERFUL AND LARGE CYCLONE CENTERED OVER IA WILL GRADUALLY WEAKEN AS
   IT BECOMES CUT OFF FROM STRONGER WLY MID/UPPER-LEVEL FLOW ACROSS THE
   SRN CONUS. AS THE FLOW REGIME OVER THE CONUS DEAMPLIFIES...A SERIES
   OF WEAK IMPULSES WILL CROSS THE GREAT BASIN/CNTRL ROCKIES AS INTENSE
   WLYS EXPAND EWD FROM NRN CA. THE LEAD IMPULSE WILL INDUCE A LEE
   TROUGH OVER THE SRN HIGH PLAINS LATE THIS AFTERNOON.
   
   ...SERN NM/FAR WRN AND SWRN TX...
   MODEST W/SWLY DOWNSLOPE FLOW IS EXPECTED THROUGH MOST OF THE
   DAY...WARMING TEMPERATURES COMPARED TO SATURDAY AND MAINTAINING VERY
   DRY CONDITIONS. TEMPERATURES WILL REACH THE 50S OVER THE MTNS WITH
   60S FURTHER E ACROSS THE PLAINS. WITH DEW POINTS HOLDING IN THE
   SINGLE DIGITS...RH VALUES WILL DROP TO 6 TO 12 PERCENT. MODEL
   GUIDANCE IS CONSISTENT WITH RAPIDLY INCREASING LOW/MID-LEVEL FLOW
   AROUND 00Z/MON. THIS SHOULD RESULT IN SUSTAINED SURFACE WINDS OF 15
   TO 20 MPH WITH LOCALIZED/BRIEF CRITICAL CONDITIONS IN THE EARLY
   EVENING.

   NWS STORM PREDICTION CENTER NORMAN OK
   0334 AM CST SUN FEB 25 2007
   
   VALID 261200Z - 271200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   INITIALLY QUASI-ZONAL MID-LEVEL FLOW WILL GRADUALLY BECOME MORE
   AMPLIFIED BY EARLY TUE AS A LARGE-SCALE TROUGH DEVELOPS ALONG THE
   PACIFIC NW COAST. BENEATH THE BELT OF STRONG MID-LEVEL WLYS...A WEAK
   LOW PRESSURE SYSTEM SHOULD BE CENTERED OVER OK MON MORNING. THIS LOW
   WILL TRACK QUICKLY EWD TOWARDS THE SERN CONUS. IN THE WAKE OF THIS
   SYSTEM...WLY SFC WINDS WILL HELP EXPAND A DRY AIR MASS ACROSS MUCH
   OF TX.
   
   ...MUCH OF WRN/CNTRL TX AND SERN NM...
   RH VALUES WILL BECOME QUITE LOW ONCE AGAIN ALONG THE HIGH PLAINS OF
   TX/NM...AS WELL AS FURTHER E INTO CNTRL TX WITH A WLY LOW-LEVEL JET
   ADVECTING DRY AIR EWD LATE SUN INTO EARLY MON. WIDESPREAD RH BELOW
   20 PERCENT IS LIKELY DURING THE AFTERNOON WITH TEMPERATURES WARMING
   MAINLY INTO THE 70S. ALTHOUGH A BROAD AREA OF 40+ MPH LOW-LEVEL
   WINDS SHOULD EXIST AROUND 12Z MON...MODEL GUIDANCE IS INSISTENT ON
   DIMINISHING WINDS RAPIDLY THROUGH THE LATE MORNING INTO THE
   AFTERNOON. AS LOW-LEVEL LAPSE RATES STEEPEN DURING THE DAY AND
   MECHANICAL MIXING ENSUES...A BRIEF PERIOD OF JUXTAPOSITION WITH
   CRITICALLY LOW RH AND SUSTAINED WINDS AROUND 20 MPH MAY RESULT.
   PORTIONS OF THE AREA MAY BE UPGRADED IN THE DAY 1 OUTLOOK IF IT
   APPEARS A LONGER DURATION OF STRONGER SURFACE WINDS WILL OCCUR.
