Utah forecast: After record-setting heat, a cooling trend
Midsummer-like temperatures in Salt Lake City Monday broke one record and tied another, but forecasters said the heat was wilting.
Shortly after 2 p.m., the high at the Salt Lake City International Airport hit 100 degrees, tying a record for the date set in 1918. Monday's low temperature of 74 already had beaten the previous record high-low for June 10 of 67, also set in 1918. Normal low for the date is 54 degrees.
But cooler air expected along the Wasatch Front on Tuesday was due to chill the high to the upper-80s, which is still unseasonably warm. The normal high for June 11 is 80 degrees.
The National Weather Service predicted a 20 percent chance of thunderstorms and rain showers on Tuesday afternoon and in the evening for the Wasatch Front, as well, ahead of overnight lows in the mid-60s.
The NWS also noted new record highs in Alpine (93 degrees, beating 91 set in 1996), Alta (76 degrees, beating 73 in 2001), Price (97 degrees, beating 94 in 1973) and on the Utah Test Range (96 degrees, beating 94 in 2001).
Record warm low temperatures were set in Alpine (62 degrees, beating 59 in 2001), Bountiful (67 degrees, beating 66 in 2003), St. George (76, beating 74 in 2010), Spanish Fork (64 degrees, beating 63 in 1990), Tooele (75 degrees, beating 74 in 1921), and Utah Test Range (70 degrees, beating 59 in 1992).
Little relief from the heat was expected in southern Utah, however. Forecasters, who put Monday's high temperatures in the triple digits, predicted just a few degrees cooling for Tuesday. Overnight lows, under clear skies, were to be around 70 degrees.
The heat and lack of precipitation triggered a "Red Flag" wildfire warning Monday for southwestern Utah's Dixie region.
The Utah Division of Air Quality rated the breathability at "Green," or healthy levels statewide. The Intermountain Allergy & Asthma had good news for allergy sufferers: only grass and oak pollen levels were noteworthy, falling in the "moderate" range.
Salt Lake City's high temperature Tuesday was pegged at 88, down significantly from Monday's 100; Ogden 84 and 95 degrees, respectively; Provo 88 and 97; Logan 84 and 94; Wendover 90 and 97; Duchesne 84 and 92; Cedar City 88 and 89; St. George 98 and 101; and Moab 94 and 102 degrees.
