Area Forecast Discussion National Weather Service Pocatello ID 110 PM MDT Thu Jun 14 2018 .DISCUSSION...Tonight through Sunday. A low pressure trough was shearing east along the Canadian border early this afternoon resulting in breezy to windy conditions across the Snake River Plain. Early afternoon observations were showing wind speeds that were falling just under Lake Wind Advisory conditions on American Falls Reservoir while nosing upwards around the lower threshold of Wind Advisory criteria across the INL. Winds will likely diminish rapidly early this evening with the loss of thermal heating. Additional energy will dig into the western extent of the trough tonight and Friday resulting in a closed low circulation developing over SW Canada Friday afternoon which gradually drifts south Friday night and Saturday. As the low drifts south, an increasing potential for showers and cooler temperatures is expected across SE Idaho starting Friday and continuing into Sunday. There have been fairly significant run to run adjustments on the placement and timing of convective precipitation bands and thus at this point nothing is certain and we have continued to maintain a strong chance mention of showers Friday through Sunday (See more on the ramifications of these heavy showers in the Hydrology section below). Huston Sunday night through next Thursday night. Long wave forecast for this period is zero steering flow over the western half of the country, with the main jet moving through southeast Alaska and Northwest Territory/Nunavut. Thus would not expect any major front to track through the Gem State, but the door is open to subtropical moisture to meander around the Great Basin, based on shortwave forecast. Expect little to none in terms of model run-to-run consistency, and potentially large differences between the ECMWF and GFS solutions. And both of these problems can be seen in the guidance today. The expectations for Mon continue to get wetter and wetter, with likely PoPs at Pocatello for both the ECMWF and GFS. By Wed, the ECMWF continues to have high PoPs with a closed low still close to the forecast area, while the GFS moves it out and the PoP lower to low chance range. There are two places with some agreement. One is that afternoon high temperatures will be much cooler than lately, highs back in the 70s (and if the GFS is correct, maybe low 80s by next Thu) and mild overnight lows. The second is no significant wind events expected during this time. Messick && .AVIATION...Upper level ridge is breaking down and starting to allow enough moisture for some clouds today, and possibly showers Fri morning. However, little impact to flight operations as CIGs should stay at mid-level or higher. The approaching trough and associated front is bringing wind, which should stay elevated somewhat tonight in the western airdromes; only KDIJ and KIDA should see variable wind tonight. The area of precipitation for the morning is limited to the three eastern airports, KDIJ, KIDA, and KPIH. At this time, conditions in the morning should be stable enough to mean only showers, with Fri afternoon having a slight chance of thunderstorms. Messick && .FIRE WEATHER...Expect breezy conditions across much of the region today as a cold front moves through the region. A low pressure system will stall over the area for the next several days and produce scattered showers and a few thunderstorms. Valle && .HYDROLOGY...A low-pressure system will set up near or just west of the state of Idaho and remain nearly stationary Friday through next Thursday. There is a modest risk that bands of heavy convective showers may create significant rises on area creaks although the placement and timing of these convective bands remains in considerable flux. For those with hydrologic concerns, it would be prudent to monitor forecast products through the weekend as this system evolves and forecasts become more certain. Huston && .PIH WATCHES/WARNINGS/ADVISORIES... Lake Wind Advisory continues through 8 PM MDT this evening for IDZ021. Wind Advisory through 8 PM MDT this evening for IDZ020. &&
