Area forecast discussion, Sep 4, 2:28 PM MDT, 11 hours 43 minutes before
Area Forecast Discussion National Weather Service Pocatello ID 228 PM MDT Fri Sep 4 2020 .SHORT TERM...Tonight through Sunday...Skies are looking quite clear with no rain or thunderstorms to be found. Hot, dry and windy conditions are expected for most of this upcoming weekend. Strong winds are expected to develop during the afternoon hours tomorrow afternoon and again Sunday afternoon for most of Southeast Idaho; meanwhile temperatures will begin soaring into the mid 90s to around 100 degrees. Heat Advisories are in effect for several areas during peak heat hours tomorrow as a result. While recreation on area lakes may look pleasant for most people this weekend, don't forget about the wind and the chop it can build up. Each afternoon looks windy; but Monday in particular just looks downright dangerous. We are holding off on issuing a Lake Wind Advisory for American Falls Reservoir at this time but be mindful there may be one issued. ND .LONG TERM...Monday through Friday...A very potent upper trough with strong cold front is expected to swing through the area early next week. MEX guidance continues to show very strong winds at the surface, a 30 degree temperature drop and snow at higher elevations. A weather change that checks the Fall Season "check boxes" indeed. At this time, the snow in the forecast in confined to Eastern Idaho areas, particularly areas that border Montana and Wyoming. Conditions begin to relax Wednesday and Thursday with temperatures gradually rebounding while high pressure build back into the region. ND && .FIRE WEATHER...A ridge of high pressure is continuing to expand across the region today and will bring near record warmth to a good portion of SE Idaho. A weak low pressure system located off the Oregon coast will move over the high pressure ridge Saturday morning helping to suppress the ridge development Saturday afternoon as daytime highs soar to record levels. Also, expecting widespread Haines of 6 across the area today and tomorrow. The break down of the high pressure ridge will allow gusty west winds to mix into the Central mountains and Snake River Plain where a Red Flag is now in place for zones 422, 475, 476, 410 and 425 during the afternoon and evening hours. Zone 411 across the Montana Divide was added to the warning though the gustier winds will be mostly for the western portion of this zone. Additional energy from the low pressure system will move over the ridge Saturday night into Sunday, diving southeast into the upper mid-west and bringing more wind to the Snake River Plain and Southern mountains where a second Red Flag is now in place covering zones 410, 413, 425, and 427. The ridge weakens and dissipates completely Monday as a strong low pressure system drops south across WRN Canada bringing a chance of precipitation, strong northerly winds, and cooler conditions to the region Monday night into Tuesday. Over the latter half of the week, the high pressure ridge builds back in along the west coast as a dry and mild Northwest flow develops over SE Idaho. Wyatt && .AVIATION...Expect continued VFR conditions and overall light winds through tomorrow morning under strong high pressure ridging. The high pressure riding starts to weaken as trough approaches from the north by Saturday afternoon. Winds will start to increase by Saturday afternoon for all TAF sites. Wyatt && .AIR STAGNATION...Areas of smoke and haze look enter the region from regional fires from the north and west tomorrow afternoon and linger across our area through the remainder of this Labor Day Weekend. Areas of denser smoke look to be likely in portions of East Idaho, similar to about a week ago. ND && .PIH WATCHES/WARNINGS/ADVISORIES... Red Flag Warning from noon to 9 PM MDT Saturday for IDZ410-411- 422-425-475-476. Red Flag Warning from noon to 9 PM MDT Sunday for IDZ410-413-425- 427. Heat Advisory from 8 AM to 9 PM MDT Saturday for IDZ051>059-075. &&
