AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PUEBLO CO
350 PM MDT MON APR 16 2007

.SHORT TERM...
(TONIGHT AND TUESDAY)

THERE ARE MANY CHALLENGES IN THE SHORT TERM...SUCH AS WHAT THE SNOW
LEVEL WL BE...AND HOW MUCH SNOW WL FALL AND WHETHER HIGHLIGHTS ARE
NEEDED.  THE UPR LOW IS NOW SITTING OVR ABOUT CENTRAL AZ AND THERE
IS A LOT OF LIGHTNING OVR UT AND A FEW STRIKE OVR CO AS WELL.  THE
LOW IS FORECAST TO MOVE BASICALLY STRAIGHT E THRU TONIGHT AND
TUESDAY ACRS NEW MEXICO.  THE MODELS HAVE CONSISTENTLY BE SHOWING A
LOT OF PCPN OVR THE CENTRAL MTS...TELLER COUNTY AND PIKES PEAK.
THE AMOUNTS ARE HOPEFULLY WAY OVER DONE...BUT HAVE DECIDED I CANNOT
IGNORE THIS CONSISTENT FORECAST. WITH THE RELATIVELY STRONG NERLY
WINDS UP THROUGH AT LEAST 700MB ACRS THE MTS AND HIGH VALLEYS
TONIGHT AND INTO TUESDAY MORNING AND THE GOOD MSTR OVR THE
AREA...ALONG WITH SOME GOOD UPR DYNAMICS TONIGHT...THIS IS A GOOD
SET UP FOR SNOW IN THE ABOVE MENTIONED AREAS.  LOOKING AT THE
SOUNDING...IT APPEARS THAT SNOW LEVELS WL LIKELY DROP TO AROUND 7000
FEET...BUT THE COLDEST TEMPS AND BEST CHANCES FOR SNOW LOOK TO
PROBABLY BE AROUND 8500 FEET. HAVE DECIDED TO ISSUE A SNOW ADVISORY
FOR LAKE COUNTY...CHAFFEE COUNTY ABOVE 8500 FEET...PIKES
PEAK...TELLER COUNTY ABOVE 8500 FEET AND NORTHERN FREMONT COUNTY.
THE 18Z RUN OF THE NAM CAME IN WITH LARGE AMOUNTS OF PCPN AND SNOW
OVR PORTIONS OF THE SW MTS AS WELL. WL JUST GO WITH A FEW INCHES OF
SNOW ACCUMULATION IN THIS AREA...BUT LATER SHIFT WL HAVE TO KEEP AN
EYE ON THIS.  FOR TUE WE LOSE THE UPR LIFT AND THE WINDS BECOME LESS
FAVORABLE...HOWEVER DURING THE MORNING HOURS THE NAME HAS MOIST
NERLY FLOW INTO THE WET AND SANGRE DE CRISTO MTS...WHICH WL LIKELY
LEAD TO A FEW INCHES OF ACCUMULATION.

.LONG TERM...

...WINDY OVER THE EASTERN SLOPES THURSDAY MORNING...
...UNSETTLED WEATHER FOR LATTER HALF OF APRIL...

UPPER LOW TO OUR SOUTH WILL MOVE QUICKLY TO THE EAST TUESDAY NIGHT...
WITH POPS DIMINISHING TO NEAR ZERO OVER THE EASTERN PLAINS BY THE
EVENING HOURS. A SHORT WAVE RIDGE WILL BRIEFLY BUILD EARLY
WEDNESDAY...AND TEMPERATURES OVER THE PLAINS WILL REBOUND
CONSIDERABLY WED AFTERNOON...POSSIBLY REACHING THE MID 70S IN SPOTS
AS WESTERLY FLOW ALOFT BEGINS TO STRENGTHEN. LAPSE RATES STEEPEN
SIGNIFICANTLY WED AFTERNOON AND A LEE TROUGH WILL DEEPEN E OF THE
MTS LATE WED AFTERNOON AND EVE AS THE NEXT SHORTWAVE MOVES IN
QUICKLY FROM THE W. GOOD LLVL CONVERGENCE E OF THE MTS MAY HELP
SPARK THE DEVELOPMENT OF A FEW TSTORMS BY LATE AFTERNOON TO EARLY
EVE. WILL INTRODUCE ISOLD POPS FOR THE WHOLE AREA THIS TIME
FRAME...ALTHOUGH BEST CHANCES WILL BE OVER THE MTS INITIALLY AND
THEN THE ERN PLAINS BY THU EVE. WINDS WILL BEGIN TO PICK UP OVER THE
MTS WED AFTERNOON AS A 75-80 KT MID-LEVEL JET MOVES THROUGH COLORADO.
COULD SEE SOME STRONG GAP FLOWS AND POSSIBLE MTN WAVE ACTIVITY BY
THU MORNING AS LLVL FLOW STRENGTHENS AND RUNS PERPENDICULAR TO THE
ERN MTN RANGES. ERN SLOPES FROM LA VETA PASS NORTHWARD TO THE WET
MTN VALLEY AND RAMPARTS WILL SEE THE BEST CHANCE OF SOME STRONG
WINDS THU MORN. HAVE BOOSTED WINDS/GUSTS FOR THIS TIME FRAME. POPS
GENERALLY REMAIN LOW WITH BEST CHANCE OVER THE N CENTRAL MTS.

GFS CONTINUES TO SHOW FAIRLY LOW QPF WITH THE NEXT WAVE...SCHEDULED
TO ARRIVE OVER THE WEEKEND. HOWEVER...LATEST RUN DOES DIG THE TROUGH
A LITTLE FURTHER TO THE SOUTH. ECMWF IS CONSIDERABLY DEEPER WITH THIS
SYSTEM AND EVEN CUTS IT OFF...ALBEIT TO OUR NORTH. WILL HAVE TO KEEP
AN EYE ON THIS SYSTEM SINCE TRACK AND STRENGTH ARE STILL A BIT UP
IN THE AIR (PUN INTENDED). ANOTHER CLOSED LOW LOOKS LIKE IT WILL
FOLLOW CLOSELY BEHIND...PROBABLY BY EARLY NEXT WEEK. FOR THE
EXTENDED...HAVE BEEN ADDING ISOLD MENTION OF THUNDER FOR EACH SYSTEM
SINCE THESE LOOK TO BE ROBUST UPPER LOWS AND OUR PRIME CONVECTIVE
SEASON IS NOT TOO FAR OFF. ROSE
