&&

.PREV DISCUSSION... /ISSUED 515 AM MDT WED APR 30 2008/

SHORT TERM...TODAY THROUGH THURSDAY NIGHT...ONE MORE WARM DAY
TODAY BEFORE BIG CHANGES TAKE PLACE.  COLD FRONT WILL MAKE ITS
WAY INTO THE WESTERN AND NORTHERN CWA LATE THIS MORNING AND
EARLY AFTERNOON...AND THROUGH THE REST OF THE CWA BY EVENING.
SCATTERED SHOWERS WILL SPREAD INTO NORTHERN CWA BEHIND FRONT
WHILE A FEW TSTMS DEVELOP ELSEWHERE THIS AFTERNOON.  DEWPOINTS
WILL BE LACKING UNTIL FRONTAL PASSAGE...SO DESPITE LEFT FRONT
QUAD OF UPPER JET AIDING THINGS...STRONG TSTMS NOT VERY LIKELY.
DEEP UPPER TROUGH OVER THE PACIFIC NW CURRENTLY WILL SLOWLY DIG
INTO THE NORTHERN AND CENTRAL ROCKIES TONIGHT WITH SURFACE LOW
OVER EASTERN CO SHIFTING INTO WESTERN KS EARLY THURSDAY MORNING.
UPSLOPE NORTHERLY FLOW AT THE SURFACE WILL COMBINE WITH UPPER
DYNAMICS AND UPPER DIVERGENCE TO CAUSE PRECIP TO BE WIDESPREAD.
CONSENSUS OF MODELS IS AN UPPER LOW OVER SOUTHEAST CORNER OF WY
THURSDAY AFTERNOON...SHIFTING INTO NW KS BY 12Z FRI.  THERE IS
STILL A LOT TO BE RESOLVED YET WITH THIS DEVELOPING UPPER LOW.
INDEED...BOTH 00Z UKMET RUN AND 06Z NAM RUN HAVE THE UPPER LOW
GOING ON MORE OF A SOUTHERN TRACK ACROSS CO.  PER HPC HEAVY
SNOW DISCUSSION...COULD BE SOME LARGE AMOUNTS OF SNOW IN OUR
MOUNTAINS AND FOR SOME LOCATIONS ON THE PLAINS MAINLY OVER THE
NORTHERN CWA FROM KDGW TO KAIA.  SO...HAVE OPTED TO GET THE
WORD OUT AND ISSUED WINTER STORM WATCHES PER BELOW.  SOME OTHER
AREAS WILL PROBABLY NEED EITHER SBS ADVISORIES OR WIND ADVISORIES
IN DUE TIME.  TIME OF YEAR SUGGESTS THAT SNOW ACCUMULATIONS AT THE
LOWER ELEVATIONS WILL NOT BE ALL THAT MUCH DURING THE DAY...
ESPECIALLY OVER NEBRASKA PANHANDLE.  STILL...STRONG NNW WINDS ON
BACKSIDE OF LOW MAY CREATE NEAR BLIZZARD CONDITIONS LOCALLY ACROSS
NORTHERN CWA DESPITE TEMPS BEING JUST ABOVE FREEZING.

LONG TERM...FRI THROUGH TUE...
EXPECTED WINTER STORM WILL CONTINUE INTO FRI BUT WILL GRADUALLY
WEAKEN FRI AS THE DEEP LOW PRESSURE SYSTEM MOVES AWAY TO THE EAST.
WINDY CONDITIONS WILL ALSO CONTINUE FRI PARTICULARLY FROM THE

ALOFT OVER THE FORECAST AREA WILL LOSE ITS CYCLONIC CURVATURE FRI
NIGHT WHILE SURFACE HIGH PRESSURE MOVES OVER THE REGION. SATURDAY
WILL BE MILDER WITH LESS MOISTURE AND LIFTING DYNAMICS. A FEW
OROGRAPHIC AFTERNOON SHOWERS WILL BE POSSIBLE OVER THE HIGHEST
MOUNTAINS SAT. MID LEVEL MOISTURE WILL INCREASE FROM THE WEST SUNDAY
AHEAD OF AN APPROACHING UPPER TROUGH. SHOWERS WILL BE POSSIBLE SUN
FROM THE MOUNTAINS WESTWARD. SURFACE LOW PRESSURE OVER CO MON WILL
PRODUCE UPSLOPE FLOW AND A SMALL CHANCE OF PRECIPITATION OVER MOST
OF THE FORECAST AREA. TEMPS MON WILL APPROACH NORMAL FOR THE TIME OF
YEAR. GENERAL UPPER LEVEL TROUGHINESS TUE WILL RESULT IN A CONTINUED
CHANCE OF PRECIP.

AVIATION...VFR CONDITIONS WILL CONTINUE TODAY.  MVFR AND EVEN IFR
CEILINGS AND VSBYS WILL BE SPREADING OVER THE CWA FROM THE NORTH
AND WEST TONIGHT IN RAIN OR RAIN CHANGING TO SNOW WITH THESE
CONDITIONS CONTINUING THURSDAY.

FIRE WEATHER...AHEAD OF THE COLD FRONT TODAY OVER ROUGHLY THE
