243 PM MDT MON MAY 30 2016

.SHORT TERM...Tonight through Wednesday...Post-frontal winds
continue to gust 20 to 30 mph across the Treasure and Magic
Valleys this afternoon. Winds will weaken with sunset, becoming
light by sunrise Tuesday. Main focus of the short-term forecast is
an intense ridge of high pressure, currently centered along the
West Coast. This ridge will shift inland over Oregon/Idaho on
Tuesday, bringing sunny skies and a drastic rise in local
temperatures. Afternoon highs will average 10 to 12 degrees above
normal by mid-week.

.LONG TERM...Wednesday night through Monday...Strong upper-level
ridge will remain over the region through the extended period and
will provide for above normal temperatures. A weak trough moving
across Western Canada Wednesday night/Thursday will suppress the
upper-level height field slightly and maintain northwesterly flow.
Temperatures approach records highs next weekend as an upper-level
cutoff low approaches California, increasing the southerly flow. Raw
model guidance approaches 100 F Saturday and Sunday which is about
20 degrees above normal for this time of year. However, this cut-off
low will also bring some moisture for a chance of afternoon
thunderstorms, mainly over the mountains. Models in fairly good
agreement with the low pressure system moving across the region
/southwest to northeast/ on Monday. This could bring increased cloud
cover, showers, and cooler temperatures early next week.


.AVIATION...VFR. Few high clouds through the evening. Surface winds
west to northwest 10-15 kts, except 15-20kts with gusts to 30 kts
east of KMUO through 03z tonight. Light winds expected overnight.
Winds aloft to 10K feet MSL: northwest 15-25 kts. No significant
weather expected until at least next weekend.
