EVENT...DEEPENING TROUGH AND MOISTURE FOR MOUNTAIN SNOWS/
LOWER ELEV RAINS...
.
SATELLITE ANALYSIS AND TRENDS...PROGRESS RIDGE IN NE GULF OF ALASKA HAS
BUILT ENOUGH TO FORCE POLAR JET ACROSS W WA AND OREGON WITH SATELLITE
WIND MAX OF AT LEAST 120KTS...POSSIBLY AS HIGH AS 150KTS NEAR KPDX AT
250MB LEVEL.  THIS SHOULD INSURE CONTINUED DEEPENING AND DIGGING OF
UPPER LOW/TROUGH NEAR THE CENTRAL IDAHO/MONTANA BORDER THIS MORNING.
DEFORMATION ENHANCEMENT DROPPING SOUTH THRU W MONTANA AND CAN PROVIDE
BRIEF HVY PRECIPITATION AS IT CONTINUES DROPPING SOUTH THRU W CENTRAL
THIRD OF THE STATE.  VORT CLOUDS OVER SW MONTANA NOT PRODUCING MUCH IF
ANY PRECIPITATION...BUT JUST TO THE SOUTH WEAKER FRONT SIDE OF POLAR JET
(90KT MAX WYOMING) MORE ALIGNED WITH PW MOISTURE PLUME AND HELPING TO
PRODUCE LIGHT TO MODERATE HIGH ELEV SNOW AND LOW ELEV RAIN N UT TO SW ND.
BUT MOISTURE TRANSPORT NOT ALL THAT GOOD...SO JET DYNAMICS AND ANY WEAK
IMPULSE WILL PROVIDE MAIN FORCING IN AREA OF DECENT MOISTURE THAT IS
ABOUT 1.5 STANDARD DEVS ABOVE THE 1948-2000 CLIMO NORMAL.
WILL CONTINUE TO MONITOR...
