Area Forecast Discussion National Weather Service Pocatello ID 205 PM MDT Thu Aug 1 2019 .DISCUSSION...Convection has started to redevelop again this afternoon, with initial development over the central mountains and to the southwest over Nevada. This is in line with several of the recent high-res runs. Next several hours should see significant strengthening of the convection as well as activity shifting east and spreading. Outflow gusts generally expected to stay sub-severe but would not be surprised to see a cell or two overachieve. Precipitable water values approach or exceed an inch across most areas so brief heavy downpours expected as well. Activity diminishes after sunset but expect redevelopment on Friday. Central mountains most favorable with shortwave feature driving north through Oregon/Washington, along with favorable jet dynamics. Moisture availability is a little less tomorrow, which should favor potential for wind gusts. This shortwave helps to flatten ridge slightly with flow aloft shifting towards the southwest, and ushering a slightly drier air mass into the region. Thus expect Saturday to be dry with a nudge upward slightly in temperature. Four-corners high rebuilds Sunday and beyond, with moisture returning to the region for at least isolated thunderstorm potential over higher elevation regions each day. DMH && .AVIATION...Convection has fired across the region early this afternoon, beginning over higher terrain regions in the central mountains and southern highlands. Have maintained VCTS at all terminals, with -TSRA for selected terminals where best chances are expected. Activity expected to diminish after sunset. Redevelopment forecast for Friday afternoon, and KSUN should be the closest terminal. Expect VFR conditions outside thunderstorm influence. DMH && .FIRE WEATHER...Ample moisture combined with multiple disturbances rotating through SE Idaho embedded within an energetic southwest flow will promote shower and thunderstorm development, with the biggest days being this afternoon/evening and tomorrow afternoon and evening, and we'll discuss each day below. For today, moisture quality is fairly rich, and we have high confidence in scattered thunderstorms from mid-afternoon through early evening across the Central Mountains (475,476,422) in particular, and this is where a Red Flag Warning is in effect. Elsewhere, isolated to scattered activity is expected, with the best chance for scattered activity across higher terrain areas south/east of the I-15 corridor. Any activity has the potential to produce gusty outflow winds, heavy rainfall and frequent lightning. Some hail can't be ruled out either. For tomorrow, another disturbance will rotate through the region, and the best chance for scattered thunderstorms will be more restricted to the Central Mountains. We have enough confidence in scattered coverage to issue a Red Flag Warning, which will be in effect from 12PM through 9PM Saturday for zones 475 and 476. Scattered thunderstorms are possible across 422, but confidence is lower. Isolated thunderstorms are expected across the remainder of SE Idaho as well, but coverage should remain more isolated. Thunderstorm activity is expected to be much less for the Sunday through Wednesday timeframe, with isoalted activity possible each day, best chance will be over high terrain areas. The best day to see the combination of critically low RH and critically high winds is Monday across the Arco Desert, and we'll continue to monitor this for any future headlines. Otherwise, hot, above average temperatures should continue through next week. AD && .PIH WATCHES/WARNINGS/ADVISORIES... Red Flag Warning until 10 PM MDT this evening for IDZ422-476. &&
