DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0309 AM CDT SUN MAR 15 2009
VALID 151200Z - 161200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
UPPER-LEVEL SPLIT FLOW REGIME WILL PERSIST INTO EARLY MON.
LOW-AMPLITUDE IMPULSES EMBEDDED WITHIN LARGER-SCALE TROUGH FROM THE
CNTRL PLAINS TO NRN MEXICO WILL REACH THE MID-MS VALLEY TO THE LOWER
RIO GRANDE VALLEY BY MON MORNING. A SERIES OF PROGRESSIVE SHORT WAVE
TROUGHS WILL ROTATE INLAND FROM THE NERN PACIFIC ACROSS THE PACIFIC
NW/NRN ROCKIES AND SWRN CANADA.
...N-CNTRL CO FOOTHILLS/FAR SERN WY/NEB PANHANDLE...
LOCALIZED/SHORT-DURATION CRITICAL CONDITIONS ARE EXPECTED DURING THE
EARLY/MID-AFTERNOON. LOW/MID-LEVEL WLYS WILL STRENGTHEN AMIDST A
WELL-MIXED THERMODYNAMIC PROFILE AND RESULT IN SUSTAINED SURFACE
WINDS OF 20 TO 25 MPH. ALTHOUGH THE ANTECEDENT AIR MASS IS DRY
/LATEST GPS PW VALUES OF 0.05 TO 0.10 IN/...MODEL FORECASTS ARE
QUITE CONSISTENT WITH INCREASING MEAN MIXING RATIOS ALONG WITH
HIGHER-LEVEL RH. AS TEMPERATURES REACH THE UPPER 50S TO MIDDLE
60S...RH VALUES SHOULD DROP TO AROUND 15 PERCENT FOR A FEW HOURS
PRIOR TO GRADUALLY RISING. OVERALL JUXTAPOSITION OF STRONG WINDS
WITH LOW RH APPEARS TOO MARGINAL TO WARRANT A CRITICAL AREA.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0357 AM CDT SUN MAR 15 2009
VALID 161200Z - 171200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
AN UPPER-LEVEL TROUGH WILL SHIFT EWD OVER THE SERN CONUS. IN THE NRN
STREAM...A VIGOROUS SHORT WAVE TROUGH WILL MOVE ACROSS THE CANADIAN
PRAIRIES...WHILE UPSTREAM IMPULSES CONTINUE TO PROGRESS FROM THE
NERN PACIFIC INTO SWRN CANADA/NWRN CONUS. A BELT OF INTENSE
MID-LEVEL WLYS WILL PENETRATE FARTHER INLAND AND STRETCH FROM THE
NRN PLAINS THROUGH THE PACIFIC NW BY EARLY TUE.
...PANHANDLE/N-CNTRL NEB...
WELL ABOVE-NORMAL TEMPERATURES AND LOW RH WILL DEVELOP ACROSS MUCH
OF THE CNTRL/SRN HIGH PLAINS MON AFTERNOON. ON THE NRN FRINGE OF
THIS AXIS...SUSTAINED WINDS MAY APPROACH 20 MPH ON THE SRN PERIPHERY
OF MORE ROBUST WLYS. MODEL FORECASTS DIFFER WITH THE STRENGTH OF
LOW-LEVEL FLOW WITH THE GFS 8 TO 15 MPH STRONGER THAN THE ECMWF/NAM.
THE LATTER GUIDANCE WOULD SUGGEST STRONG WINDS ATTENDANT WITH LOW RH
WOULD BE OF LIMITED AREAL AND TEMPORAL EXTENT.
