What forecasters said that day
The local office's own words before this heat advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Salt Lake City, UT wrote its last area forecast discussion before this heat advisory went out at Jul 5, 4:28 AM MDT, 9 hours 36 minutes earlier.
Area forecast discussion, Jul 5, 4:28 AM MDT, 9 hours 36 minutes before
Area Forecast Discussion National Weather Service Salt Lake City UT 428 AM MDT Mon Jul 5 2021 .SYNOPSIS...High pressure over the Great Basin will continue to bring hot temperatures to the area through much of the week. A temporary increase in moisture will bring some showers and thunderstorms to the area through Monday, otherwise mainly dry conditions will prevail. && .SHORT TERM (Through 12Z Thursday)...A modest moisture axis within an anticyclonic flow around a western Colorado ridge axis resides across the forecast area this morning. A weak wave embedded within this flow enhanced showers across northern Utah early this morning, and continues to lift across northeast Utah/southwest Wyoming. Meanwhile isolated showers in the wake of this feature have developed across northern Arizona and south central Utah, and will likely persist through the morning hours. Meanwhile a better defined upper trough currently extends across central Idaho back into north central Nevada. As this feature continues east today, veering low level flow across the forecast area will allow slightly cooler and drier air to spread from west to east across the area. As such by this afternoon anticipate the convective threat will become increasingly confined to the eastern third of the forecast area. As such have largely confined higher flash flood potential to the Capitol Reef/San Rafael Swell area. Mid level ridging is forecast to amplify across the region Tuesday through Wednesday allowing for a warming and drying trend. Lingering moisture may still support isolated convection over the higher terrain, however the primary focus will be warming temperatures with maxes once again reaching the 100F mark along the Wasatch Front by Wednesday, and near 110F around St George and Zion. .LONG TERM (After 12Z Thursday)...Anticipating another rather unseasonably hot day on Thursday with high pressure remaining in place. Maxes will average 10F above seasonal normals, but ensemble guidance is becoming increasingly bullish in showing a Pacific Northwest trough moving over the top of the ridge Thursday afternoon into Friday morning, weakening it, shifting it southward, and allowing a mostly dry front to move into the area. As a result, maxes on Friday should be a bit less hot, most likely around 5F above seasonal normals, with less in the way of cooling for southern Utah. For the upcoming weekend and into early next week, guidance is in good agreement that high pressure will strengthen as the ridge axis shifts back over the area, resulting in a warming trend as conditions remain dry. Confidence is high in this scenario, though there is some spread into the guidance as to how quickly the ridge will strengthen. && .AVIATION...KSLC...The SLC terminal will see VFR conditions through the morning with decreasing cloud cover. Light winds are expected to becoming prevailing southerly by 12Z, shifting to the northwest between 17Z and 19Z. Rest of Utah and southwest Wyoming...VFR conditions are expected across the area throughout the valid TAF period. Showers across northern Utah may bring a few spots of gusty and/or erratic winds before moving out of the area by 12Z. Additional isolated showers will continue through the early morning for portions of central and southern Utah, primarily east of I-15, resulting in a small threat of gusty winds. Some additional scattered convection will bring a threat of gusty and erratic winds to the higher terrain, primarily across northern Utah, during the afternoon and early evening hours. && .FIRE WEATHER...Moisture which spread northward across the area Sunday will remain in place mainly across areas east of I-15 today, allowing for isolated to scattered showers and thunderstorms. The strongest storms will be capable of producing locally heavy rain in addition to strong gusty winds. Meanwhile a more stable airmass will spread into western Utah limiting any potential for thunderstorms across this area. High pressure aloft will strengthen across the region Tuesday into Wednesday allowing for a warming and drying trend, with lingering moisture allowing for isolated afternoon showers and thunderstorms over the higher terrain. This warming trend will push max temperatures to degrees or so above normal by Wednesday afternoon. A weather system forecast to cross the northern Rockies Thursday will bring an increase in westerly winds across northern and central Utah. These winds will bring the potential for critical fire weather conditions across most northern zones Thursday afternoon. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...None.
