NWS Pocatello, ID wrote its last area forecast discussion before the first event at Jul 27, 1:11 PM MST, 5 hours 34 minutes earlier.
Area Forecast Discussion National Weather Service Pocatello ID 211 PM MDT Sat Jul 27 2019 .SHORT TERM...Tonight through Monday. Expect mainly isolated thunderstorms and scattered showers in the Upper Snake River Highlands. Will be most likely in the Island Park area south through Driggs and Victor. Isolated storms are also possible across eastern Custer County and northern Butte County. Much lesser chances will occur through sunset southwest of those regions. Will have widespread dry conditions on Sunday with some 20 to 25 mph wind gusts in the Snake River Plain. There will be a much increased chance of showers and thunderstorms on Monday as an upper level system moves through Idaho. Temperatures are expected to remain above normal Sunday and Monday. GK .LONG TERM...Tuesday through Saturday. The trend in the long term is hot conditions with isolated thunderstorms expected Wednesday through Saturday. Temperatures are expected to remain above season normals for late July and early August. GK && .AVIATION... Will have VFR conditions through Sunday. Have isolated thunderstorms in southeast Idaho this afternoon and evening and have VCTS at all TAF sites other than Burley and SUN. Sunday will be clear skies across the board. Expect 10 to 15 knot upvalley afternoon winds at PIH and IDA and SUN. GK && .FIRE WEATHER... A shortwave trough is expected to generate iso to sct showers and iso t-storms this afternoon across the Central Mntns, northern half of the Snake Plain (much of Zone 410), and the MT/WY border regions, with all activity shifting east over time. Hi-res HREF ensemble members and HRRR offer a reasonable consensus on this scenario. Unlike yesterday when widespread clouds prevented sfc heating and destabilization, satellite trends reveal our region has cleared from the Snake Plain west, and cumulus development is in progress across the Central Mntns as we warm toward convective temps. Latest SPC mesoanalysis shows a weak capping inversion of warmer air up around 3,000 feet has nearly mixed out, with SBCAPE (surface instability) values now 500-1,000 J/kg north/west of the Snake Plain, so we should be a go for storms. The overall severe wx risk is low, but rising DCAPE (downdraft instability) values 1,000+ J/kg and still an "inverted-V" flavor to NAM soundings due to fairly dry low-levels suggest that storms will be capable of producing gusty/erratic outflow winds in excess of 45 MPH, and isolated storms north of Challis are already producing abundant lightning. These will be the greatest fire wx threats today, especially for Zones 476/410/411. We still feel comfortable with the iso storm coverage currently in the forecast, so we will not be issuing a Red Flag. Storms should largely be out of Zone 476 by 7 PM, ending everywhere by 11 PM. Sun looks drier and breezy as a westerly zonal flow cuts off monsoon moisture to our south. Min RHs may drop below 15% critical thresholds in NE Zone 425, western Zone 410, and the valleys of Zone 476. Winds may also approach critical thresholds in portions of the Snake Plain, but overall seem a bit marginal for pulling the trigger on a Red Flag at this time. Zone 476 will be very close across the valleys, but even here the strongest winds will focus on the mid and upper slopes, a bit displaced from the driest low-level air in the valleys. Will headline the near-critical conditions in the FWF, but here too have opted against a Red Flag. No t-storm issues are expected, but that will change Mon as another weak shortwave approaches from the SW. This feature is impossible to clearly identify upstream today, so confidence in how it will impact our region is on the low side, but model consensus favors iso to sct showers/t-storms regionwide Mon afternoon. Will hold storm coverage at iso for now, but lightning and perhaps gusty winds could again be risks. The trade-off will be slightly higher RH values and slightly lower winds, all shy of critical. RHs may dry Tues/Wed, but we will need to monitor the evolution of monsoon moisture rotating around a high pressure ridge across the Four Corners. - KSmith/GK .PIH WATCHES/WARNINGS/ADVISORIES... None. &&
