630 PM MDT TUE APR 19 2005

.DISCUSSION...
WIDESPREAD PRECIP IN SOUTHERN HALF OF FCST AREA.  UPPED POPS TO
CATEGORICAL TO ACCOUNT FOR THIS AND UPPED TO SCATTERED THUNDERSTORMS
THROUGH MIDNIGHT AS VERY WIDESPREAD THROUGH SNAKE PLAIN AND SOUTHERN
HIGHLANDS.  LITTLE ELSE TO CHANGE AS THINK SNOW LEVELS STAY HIGH TIL
WELL AFTER MIDNIGHT WHEN COLD AIR FROM SOUTH STARTS TO WORK BACK
NORTH...ODDLY BURLEY COLDEST SPOT IN CWA RIGHT NOW AT 34 WITH TEMPS
WELL INTO 40S MOST MOUNTAIN LOCATIONS AND EASTER PART OF SNAKE
PLAIN.
GK
&&

.PREV DISCUSSION...COMPLEX WEATHER SCENARIO TAKING AIM ON EASTERN
IDAHO FOR THE SHORT TERM. CURRENTLY...UPPER LOW CENTERED OVER
SOUTHERN NEVADA TRACKING NORTHEAST. CLOUD TOPS ARE STARTING TO COOL
WITH A BAND OF PRECIP DEVELOPING OUT AHEAD OF THE LOW ACROSS CENTRAL
AND NORTHERN UTAH WITH ISOLD TSTMS AS WELL. THIS PRECIP BAND
STRETCHES ALL THE WAY UP TO THE MAGIC VALLEY. THIS BAND IS
DEVELOPING ALONG AN INVERTED SFC AND MID-LEVEL TROUGH WHICH IS ALSO
DEPICTED IN THE MODELS. THIS WILL BE THE FOCUS FOR THE HEAVIEST
PRECIP AS THE SFC LOW DEEPENS OVER THE SOUTHERN HIGHLANDS TONIGHT.
SNOW LEVELS WILL BE RATHER TRICKY TO NAIL DOWN AS WARMER AIR GETS
DRAWN UP AHEAD OF THE LOW AND THE COLDER AIR REMAINS TO THE WEST.
CASE IN POINT...TEMPS AT 2 PM ARE IN THE 30S IN THE MAGIC VALLEY AND
INTO THE 50S IN THE SNAKE PLAIN. WILL HIT THE POPS AND QPF HARDEST
OVER THE SOUTHERN HALF OF THE CWA...INCLUDING POCATELLO AND BURLEY.
18Z NAM SHOWS THE COLDEST AIR OVER THE EASTERN MAGIC VALLEY WHERE
RAIN THIS EVENING MAY CHANGE OVER TO ALL SNOW LATER TONIGHT. IF THAT
HAPPENS...A SNOW ADVISORY MAY BE NEEDED BASED ON QPF AMOUNTS OF AT
LEAST A QUARTER INCH TONIGHT THROUGH WED AM. THE SOUTHERN HIGHLANDS
WILL SEE AMOUNTS APPROACHING 8 INCHES ESPECIALLY AT HIGHER
ELEVATIONS. WILL CONTINUE WITH RAIN CHANGING TO A RAIN SNOW MIX IN
THE VALLEYS OVERNIGHT AND INTO WED AM WITH UP TO 4 INCHES OF WET
SNOW POSSIBLE...ESPECIALLY ON THE BENCHES.

UPPER LOW WILL BE A SLOW MOVER WITH A BLOCKING HIGH SITTING OVER
SOUTHERN CANADA. BY THURSDAY...THE LOW SLIDES WEST WITH THE HEAVIER
PRECIP FOCUSED AROUND THE CORE OF THE LOW...MEANING THE HIGHEST POPS
WILL BE OVER THE CENTRAL MTNS WITH SCATTERED POPS ELSEWHERE. BY
FRIDAY...THE LOW IS EXPECTED TO MOVE INTO WA AND OR STATES WITH
DRIER AND WARMER AIR STARTING TO MOVE IN FROM THE SOUTHWEST.  WAW

EXTENDED FORECAST...SATURDAY THROUGH TUESDAY. GFS SHOWS AN UPPER
RIDGE BUILDING OVER WY ON SAT...WHICH SHOULD LIMIT CHANCES FOR
PRECIP AND RAISE TEMPS. MOS SHOWS A 10 DEG INCREASE FOR SAT FROM THE
PREVIOUS RUN.  MAY BE A LITTLE EXCESSIVE...BUT WILL AT LEAST FOLLOW
THE TREND. A SPOKE OF SHORT WAVE ENERGY FROM THE CLOSED LOW OF THE
NRN CA COAST MAY SET OFF A FEW SHOWERS IN THE CENTRAL MTNS.  THE GFS
BRINGS THE UPPER LOW INTO THE PAC NW ON SUNDAY...WITH ONE CENTER IN
SW OR.  WITH ALL OF ID UNDER CYCL FLOW...WILL INCREASE POPS FOR THE
CWA SUN AND MON. WILL KEEP SOME POPS MON NITE IN RESPONSE TO THE GFS
DEPICTED FRONTAL BNDRY...WHICH WASHES OUT ON TUE. HEDGES
