Area Forecast Discussion National Weather Service Pocatello ID 323 PM MDT Mon Jun 17 2019 .SHORT TERM...Today through Wednesday...Expect northwest flow through Tuesday. A weak wave is moving through the flow today which will bring isolated to scattered showers and thunderstorms for the Central Mountains, Big Lost range, Caribou Highlands,and the Eastern Highlands. Expect drier conditions on Tuesday with only precipitation expected in the our northeast areas around Island Park. Look for even drier conditions on Wednesday across the area in breezy zonal flow. Temperatures may increase slightly tomorrow, but really you should not notice a difference. Temperatures will be around normal. Our next weather concern will change over to increasing wind speeds starting Tuesday. Winds will increase in the 15 to 25 mph range out of the southwest with some gusty conditions; however the stronger winds are forecast for Wednesday. Expect wind speeds in the 20 to 30 mph range across the Snake River Plain during the afternoon/evening. Gusts to 40 mph are possible. Temperatures will be slightly below normal on Wednesday. TW .LONG TERM...Thursday through Monday.Thursday through next Monday. Although there are some slight differences with the low dropping across the Divide into the state of Idaho later this week, the trend is toward cooler and wet conditions. By Friday, we will only be in the 60s for afternoon temperatures at lower elevations. The mountains, will be in the 40s and 50s with our really high elevations potentially stuck in the 30s. What a way to welcome Summer 2019! That storm shifts east Saturday, with lingering showers and storms across most areas EXCEPT the Magic Valley, Lower Snake Plain, South Hills/Albion Mountains and Raft River Region. It looks pretty breezy, especially on Thursday across all of eastern Idaho. In fact, if current trends hold expect some pretty rough chop on many of our lakes, at the very least. For the latter half of the weekend into early next week, the models are getting a bit out of alignment. We should warm up ahead of the next storm moving into the Pacific Northwest. The question is when and where we might see rain and thunder. The trends are drier for Sunday except for the central mountains, Island Park, and south along the Wyoming border toward Soda Springs. The Blend of Models is similar but not totally removing precipitation from the Snake Plain. Both increase the potential for showers and storms Monday, although the ECMWF is still drier compared to the GFS. The Blend of Models also increase that chance of showers and storms. We followed pretty much what the Blend was forecasting. Keyes && .AVIATION...VFR conditions expected outside of shower and thunderstorm activity. All TAF sites except BYI are included in the VCTS mention. Best chances again at KSUN and KDIJ, although shower and thunderstorm activity is expected to meander into the Snake Plain after 21Z this afternoon, and a broad outflow boundary is expected to sag south and west through KIDA, KPIH and possibly KBYI. Best chances for this are between 00-03Z, and the outflow boundary could produce gusts to 35kts, similar to yesterday. Activity is expected to diminish by 03Z. Gusty W/SW winds expected to develop Tuesday afternoon for BYI, IDA and PIH with 10-20 kt winds common. Isolated thunder chance possible for KDIJ or KSUN between 18-03Z tomorrow. AD && .FIRE WEATHER...Isolated to scattered showers and thunderstorms are expected today for most higher elevation zones. This includes 411, 413, 475, 476, and 422. This activity will have the potential to produce gusty outflow winds and frequent lightning. Additional isolated to scattered shower and thunderstorm activity is expected on Tuesday, but with less coverage overall. Tuesday coverage should be relegated to zones 411 and 413. A strong cold front will sweep through the region Wednesday, with widespread gusts in the 25-35 mph range. Strongest winds expected in mid/upper slopes and across 425 and 410. Stronger winds are expected Thursday, with gusts to 45 mph possible for these areas. An area of low pressure will then swing through the region late Thursday into Friday, bringing an increase in shower activity and near record cool temperatures for this time of year. Temperatures should rebound by the weekend, but remain 5-10 degrees below climatological averages. Shower chances will continue through the weekend, mainly in high terrain areas. AD && .HYDROLOGY...The warm June temperatures along with light to moderate rain has continued to melt the high-elevation snow, keeping some rivers and streams running high. The three main concerns continue to be the Big Wood River at Hailey, the Big Lost River at Howell Ranch, and the Big Lost River below Mackay Reservoir. The Flood Warning has been downgraded to a Flood Advisory for the Big Wood at Hailey, which is expected to remain moving back and forth between minor flood stage and action stage through Wednesday morning before dropping back into action stage and staying through the end of the week. A Flood Advisory has been continued for the Big Lost at Howell, as it's expected to hover near minor flood stage through Wednesday morning. The Mackay Reservoir is getting close to filling. It is currently at around 99 percent full. The outflow for the Big Lost below Mackay reservoir has been increased to 1400-1500 cfs, just below flood stage. The reservoir should fill tonight into tomorrow morning with current inflow. Flow may increase slightly above 1500 cfs maybe up to 1700 cfs Tuesday through Thursday after the reservoir fills and then begin to go back down by the end of the week with cooler temperatures. TW && .PIH WATCHES/WARNINGS/ADVISORIES... None. &&
