What forecasters said that day
The local office's own words before this excessive heat warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Pocatello, ID wrote its last area forecast discussion before this excessive heat warning went out at Jul 5, 1:49 PM MDT, 13 minutes earlier.
Area forecast discussion, Jul 5, 1:49 PM MDT, 13 minutes before
Area Forecast Discussion National Weather Service Pocatello ID 149 PM MDT Mon Jul 5 2021 .DISCUSSION... An upper level disturbance is departing the region this afternoon. A few thunderstorms have developed as that system interacts with very moist air. Most of the activity should be east of the Magic Valley and should dissipate this evening. Locally heavy rain along with gusty winds is possible with these storms. Ridge of high pressure begins to amplify on Tuesday. This will push the heat back into the region with temps in the upper 90s to near 100 likely across the eastern Magic Valley on Tuesday. Will issue excessive heat warning for the eastern Magic Valley Tuesday. Some models are hinting that an isolated storm or two is possible across the central mountains or southern highlands. However, most of the models favor keeping forecast dry. On Wednesday, the ridge axis is centered over eastern Idaho just ahead of a cold front. We expect to see the hottest temperatures this week Wednesday with highs in the upper 90s to around 100 from Blackfoot south and weak. Heat advisories and warnings will be issued for Wednesday for this area. We may see winds pick up later in the afternoon on Wednesday as the cold front approaches the area and isolated thunderstorms are possible as well. Temperatures look much cooler for Thursday and Friday in the wake of the front. Not expecting heat headlines for either day. Hanging on to a slight chance of thunderstorms around Island Park on Thursday with residual moisture hanging around. There's a possibility that the heat could build back in over the weekend if the ridge restrengthens but some model solutions show systems moving through Idaho as well. So, there's definitely some uncertainty with temperatures over the weekend. 13 && .AVIATION...Showers and thunderstorms have redeveloped this afternoon and will continue into this evening. We have included -SHRA VCTS or VCTS at all TAF sites during this period. Based on trends, we will likely be updating TAFs "on the fly" instead of being able to get too much in front of things. If a storm passes over an airport, locally heavy rain with lower visibility and ceilings are likely, with potential for gusts over 30kts. Keyes && .FIRE WEATHER...Showers and thunderstorms have redeveloped this afternoon. The primary focus remains across Zones 411, 413 and 476 for more scattered lightning coverage, which is where today's RED FLAG WARNING remains in effect through mid-evening. Other areas should see isolated thunderstorms. We are expecting "wet" storms with some producing over 0.25 inches, with some storms also producing gusts over 35mph...and MAYBE some small hail. The latter is low potential. High pressure builds across the region after today with moisture dwindling. While we might see a few mountain storms tomorrow, the chance is NOT included in any forecast as chances are under 15 percent, and in reality around 5-10 percent only. A low passes to our north Wednesday. Winds pick up across central and eastern Idaho, along with isolated dry thunderstorms. The combination of winds and low humidity may require RED FLAG WARNINGS for portions of the central mountains, Zone 413 and the Snake Plain. Throw in isolated dry storms in these areas, would just add to the situation even more. As another low passes to our north Thursday, expect more strong winds and low humidity, and potentially another RED FLAG WARNING event for most, if not all, of our fire districts. We will look at if we need headlines after we get done with today's round of critical fire conditions. Another thing to throw in is poor overnight recovery over portions of the central mountains and also the highlands south of the Snake Plain. More extreme heat is expected tomorrow and Wednesday over the Magic Valley, Snake Plain and Zones 413 and 427. Other areas will see more localized extreme heat conditions. A ridge builds over the weekend, bringing hot and very dry conditions to central and eastern Idaho. Keyes && .PIH WATCHES/WARNINGS/ADVISORIES...
