Area Forecast Discussion National Weather Service Pocatello ID 203 AM MDT Fri Aug 2 2019 .SHORT TERM...Today and Saturday. Another day of storms is on tap for portions of central and eastern Idaho into this evening. There is still a pocket of mid level moisture trying to skirt our western areas, especially the central mountains. That could lead to a shower or two this morning generally west of 93 and north of 75. As we go into this afternoon, we are watching another weak "wave" lifting northeast across central Idaho. This will lead to another round of scattered thunderstorms across that region. With higher amounts of moisture available for thunderstorms today, locally for locally heavy rainfall along with gusty winds. Some small hail is possible with the strongest of storms. At the moment, we are not expecting the widespread rainfall we saw yesterday across the Upper Plain extending into the Island Park area and toward the Big Holes. We should also see isolated thunderstorms developing across the southern and eastern benches of the Snake Plain, lifting northward across the Plain toward the Montana border. Speaking of that area of widespread rain, while nothing is expected until later this evening up that way...that higher amount of surface moisture might fuel storms earlier in the afternoon or fuel more storms that forecast this evening. Moisture will be more limited overnight and Saturday. The concern is for isolated dry thunderstorms developing from around Gilmore Summit and the Lost River Range toward Monida Pass and Island Park. We may also see a few storms fire across the Marsh Highlands northeast toward the Big Holes. Otherwise, look for temperatures running on average 5 degrees above normal. Keyes .LONG TERM...Sunday through next Friday. We look to remain in constant southwest flow with monsoon moisture getting pulled into the state almost daily. This should help fuel the potential for showers and thunderstorms. Right now, confidence on pinpointing coverage or rainfall amounts is low on any given day...but expect the highlands and mountains to see a better chance overall vs the Snake Plain. We look actually cool off a bit as we get into next week, but still running fairly close to average, if not just above, for August. Keyes && .AVIATION...Monsoon ridge remains anchored near the 4-corners as a weak Pacific low pressure system lifts ENE across WRN Canada. The numerical models continue to produce scattered thunderstorm activity across the CNTRL mountains while the HiRes convective models are adding isolated convection along the SE mountains from Oakley to Inkom to Driggs. We will consider adding VCTS to the KBYI and KPIH terminals in addition to what is already forecast at KSUN and KDIJ. Outside of any thunderstorms, conditions should remain VFR. Huston && .FIRE WEATHER...The monsoon high pressure ridge will remain anchored near the 4-corners region today as a weak Pacific disturbance lifts ENE across WRN Canada. The numerical models continue to highlight scattered thunderstorm activity across the CNTRL mountains today where a Red Flag Warning remains in effect. HiRes convective models are indicating the potential for isolated thunderstorms along the SE mountains from Oakley to Inkom to Driggs as well this afternoon. The next monsoon push is expected to work north through Utah Saturday night impacting SE Idaho Sunday, particularly the SE mountains where moisture levels remain high enough to support widespread wetting rains with the isolated to scattered thunderstorm activity. Big question here is whether the monsoon cloud cover will be dense enough to suppress daytime heating and thunderstorms. Lingering diurnal thunderstorm activity continues into Monday and Tuesday as a low pressure system sets up off the Oregon coast with SE Idaho remaining under the influence of the monsoon ridge still anchored over the 4-corners region. The pattern does not appear to change until Thursday, per the operational GFS model, when a much drier SW flow associated with the low off the coast begins to overspread SRN Idaho. Drier conditions continue into Friday as the low ejects NNE through Washington and eventually east along the Canadian border Saturday. Although stable conditions are anticipated with the ejecting low...drier humidity and increasing winds will likely result in increasing fire behavior for ongoing fires. Looking at the current forecast for Thursday through Friday, it appears that the National Blend of Models would like to keep a mention of thunderstorms across the region. We will be watching the trends on these differing perspectives as we work our way deeper into the forecast period next week. Daytime temperatures remain above normal throughout the forecast period. Huston && .PIH WATCHES/WARNINGS/ADVISORIES... Red Flag Warning from noon today to 9 PM MDT this evening for IDZ475-476. &&
