What forecasters said that day
The local office's own words before this red flag warning 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 red flag warning went out at Jun 20, 9:13 AM MDT, 5 hours 56 minutes earlier.
Area forecast discussion, Jun 20, 9:13 AM MDT, 5 hours 56 minutes before
Area Forecast Discussion National Weather Service Salt Lake City UT 913 AM MDT Wed Jun 20 2018 .SYNOPSIS...High pressure will bring a warming and drying trend through Thursday. A series of weak storm systems will bring somewhat cooler weather to the forecast area Friday through the upcoming weekend. && .DISCUSSION... Impacts... * Very warm today and tomorrow across southern Utah. * Critical Fire Weather conditions possible Thursday into the weekend. Antecedent Conditions... Extreme Drought is occurring from south of Provo south to Cedar City and to the southeast. Severe Drought is occurring surrounding the Extreme Drought, in areas from Ogden southward and Duchesne to the Arizona border. Drought conditions scale down to Abnormally Dry along the Idaho and Wyoming border. Big Picture... During the past 5 days, flow across the Pacific has transitioned from zonal to slightly amplified. Water Vapor Satellite shows a ridge centered over Baja California, amplified north into Oregon. A disturbance is off the Oregon and northern California coast. Local Observations and Trends... 00Z KSLC RAOB shows a 1.5C subsidence inversion near 640mb with moderate northwest mid level flow and strong northwest flow aloft. Precipitable Water values range from 0.20"-0.33" mountains to 0.50"-0.75" northern valleys. A 1021mb surface anticyclone is located across northwest Wyoming, with a 1009mb surface cyclone southwest of Nevada. This is creating a 9mb northeast pressure gradient across the state. 24 hour trends: * Precipitable Water 0.10"-0.15" higher south central and southeast Utah. * Temperatures are between 5F cooler and 5F warmer * Dewpoint Depression 5-15F lower (moister) except 5F higher (drier) across the north. Forecast... Going forecast for tonight is in great shape. Ridging surface and aloft providing stable conditions. It will continue to warm and dry today. No significant changes to the forecast. .PREVIOUS DISCUSSION... Mid level ridging noted in early morning satellite imagery and objective analysis across the Great Basin will translate eastward today, allowing a dry, warm, and stable airmass to overspread the forecast area. This will allow max temps to climb several degrees over what was observed Tuesday, particularly across the north. As this ridge axis continues east tonight into Thursday, increasing southwesterly flow aloft will advect a very warm airmass into the region, with max temperatures expected to run 10 or so degrees above climo. A shortwave trough which is forecast to brush by the area Thursday night into early Friday will push a mostly dry cold front through the region, with the only real threat for showers remaining minimal, and largely confined to the higher terrain north of I-80. With the passage of the cold front max temperatures should run close to climo in the north Friday, and a few degrees above in the south. Late Friday through Saturday afternoon will largely be a break between shortwave troughs, with an increase in winds and temperatures ahead of the next system that is expected to drop in from the Pacific Northwest. This next trough looks stronger and a bit more of a direct hit on northern Utah, especially with regards to low level cold advection and winds associated with the front. Have increased winds for Saturday afternoon, especially for post- frontal winds in the northwest desert. As far as precipitation goes, the best moisture and mid-level forcing still look to remain northeast of much of the forecast area. Have maintained some low end POPs across the northeast and the northern/central mountains, but in general the best activity should be across Idaho and Wyoming. As the trough digs into Colorado on Sunday, continued shower activity is possible across NE Utah and Uinta Co. Wyoming. Sunday should also yield a noticeable cool-down virtually area-wide, with a persistent northwest flow in the lower levels. Temperatures rebound for the beginning of the work week, as the trough exits the Rockies and ridging builds over much of the western CONUS. Models hint that just enough mid-level moisture may linger under the ridge to allow for mountain convection Tuesday and Wednesday, so have added some low level POPs to typical locations both afternoons. Otherwise, expect hot and dry weather to persist through mid-week. && .AVIATION... VFR conditions are expected to prevail at KSLC through the TAF period. Southerly winds will become calm about 16Z with northerly winds becoming established no later than 17Z. The switch back to southerly winds will happen around 03-04Z this evening. && .FIRE WEATHER... ERC values are running between the 80th and 96th percentile across eastern and southern Utah, and rising above the 50th percentile across northern and west central Utah. Values are steady or rising except falling along the northern Utah border. 100/1000 hour fuel moisture has risen just above historical lows across most areas. A ridge of high pressure will bring dry and stable conditions across the state today. A system will enter Oregon today and progress into the northern Rockies tomorrow. This will support a dry cold front crossing northern and portions of central Utah tomorrow afternoon. Gusty southwest winds will develop with a Haines of 6, much warmer temperatures and single digit RH most locations. Critical fire weather conditions are possible where fuels are critical. This boundary will progress to the Arizona border Friday, bringing a gusty northwest flow. It will be almost as warm, with nearly as low RH and a Haines of 6 across the south tomorrow. Thus, critical fire weather conditions may persist. The boundary lifts northward into southern Utah Saturday with many variables being similar to Friday there. A gusty westerly wind may present a continuation of critical fire conditions across southern Utah Saturday. The next system dives southeast from Washington Saturday morning across eastern Utah Saturday night and Sunday. This will bring another dry cold front through the region. Temperatures trend warmer through tomorrow, cooler Friday, warmer Saturday then much cooler Sunday. Tomorrow will be the driest day with single digit RH across most of the state, rising a bit Friday across the north, little changed Saturday and a bit higher Sunday. No convection expected today, with isolated to scattered showers and thunderstorms primarily across the northern mountains Thursday through the weekend. && .SLC WATCHES/WARNINGS/ADVISORIES...
