RADAR SHOWING SNOW OVER THE NORTHERN SNAKE RIVER PLAIN SLOWLY SPREADING SOUTH IN RESPONSE TO THE NEXT COLD AIR SURGE. NOT MUCH MSTR AVAILABILITY...SO EXPECT SNOW AMOUNTS TO BE LIMITED.

TEMPS WILL RECOVER ON SAT AND SUNDAY. HEDGES LONG TERM...SUNDAY NIGHT THROUGH THURSDAY. MODELS ARE IN AGREEMENT THAT THE WESTERN RIDGE WILL GRADUALLY BUILD INTO THE REGION SUNDAY NIGHT THROUGH TUESDAY. NORTHWEST FLOW ALOFT WILL SUPPORT WARM AIR ADVECTION AND UPSLOPE FLOW OVER THE CENTRAL MOUNTAINS AND PARTICULARLY OVER THE EASTERN AND UPPER SNAKE HIGHLANDS. THIS WARRANTS THE MENTION OF A SLIGHT CHANCE OF SNOW IN THOSE AREAS THROUGH TUESDAY...THEN DRY WEDNESDAY AS UPPER RIDGE SETTLES INTO THE AREA. WINDS ALOFT WILL BE STRONG ENOUGH TO PROMOTE MIXING SO THE WARMER MEXMOS TEMPERATURES SHOULD BE REALIZED. THEREFORE...TRENDED TEMPERATURES ABOVE CLIMO BEGINNING MONDAY.

THE ECMWF...ON THE OTHER HAND...SWINGS A TROUGH THROUGH THE PACNW AND INTO IDAHO ON THU.
