Area forecast discussion, Aug 6, 1:52 PM PDT, 15 hours 17 minutes before
Area Forecast Discussion National Weather Service Boise ID 252 PM MDT SAT AUG 6 2016 .SHORT TERM...Tonight through Monday...A short wave which enhanced the convection this morning through early this afternoon was lifting to the northeast and away from the area. The bulk of the showers and thunderstorms associated with the wave was to our northeast, although isolated showers were still occurring in the Western Magic Valley and in Southeast Oregon between Burns and Baker City. For the remainder of the afternoon through this evening, expect the convection to remain isolated and located in Southeast Oregon and in Western Magic Valley/West Central Mountains of Southwest Idaho. Another short wave near the northern California coast will lift northeast across our area late tonight through Sunday. This will bring a new round of convection, with scattered showers and isolated thunderstorms expected across most of the area (except dry east of Mountain Home). A drier stable air mass will move in behind the short wave while scattered showers and thunderstorms will linger through the afternoon across the Boise/West Central Mountains. A slow-moving upper low near Vancouver Island will move into Washington Sunday night through Monday. Moisture with the system will remain near the center of upper low with dry weather expected across our area late Sunday night through Monday. However, as the upper low moves closer to our area, it will bring a slight cooling trend with highs around 5 degrees below normal on Monday. .LONG TERM...Monday night through Saturday...The long term forecast remains dry with below normal high temperatures through Thursday then near normal through at least Saturday. Models are still indicating a slow moving upper low will continue its trek over the Idaho panhandle and lift north and east on Wednesday. This will keep the area relatively cool, but precip will remain to our north. By the end of the week, models are indicating the northerly flow behind the low will begin to flatten out then ridging will build in around Friday, thus bringing out temperatures back to near normal. && .AVIATION...Mostly vfr with patchy smoke in valleys causing MVFR visibilities. Expect afternoon isolated showers and thunderstorms, mainly in the mountains, then more storms overnight into Sunday morning, mainly north of a line KJER-KREO. Gusty winds up to 40 kts are possible near storms. Otherwise, surface winds generally 10 kts or less. Winds aloft near 10 kft msl, southwest 10-15 kts. && .BOI WATCHES/WARNINGS/ADVISORIES...
