This week, Modesto should see first triple-digit temperatures of the year

The Modesto area will experience a 27-degree rise in daily high temperatures between Monday and Sunday, according to the National Weather Service.

The predicted low temperature by Saturday night – 72 degrees – is just a few degrees shy of Monday’s forecast high of 75.

The historical average high temperature for June 12, according to MID, is 87 degrees.

The week will see a steady climb in daily highs – 84 Tuesday, 90 Wednesday, 93 Thursday, 99 Friday, 100 Saturday and 102 Sunday, which is Father’s Day.

The next few days and nights, at least, area expected to have northwest winds of 5 to 13 mph.

The nighttime lows also will trend upward: around 54 Monday night, 59 Tuesday, 63 Wednesday, 67 Thursday, 70 Friday and the aforementioned 72 Saturday.

The weather service warns that when the hotter days arrive, long outdoor exposures will increase chances for heat-related illness, especially for children, the elderly and other sensitive groups. Heat stress also could strike livestock, with limited heat relief overnight.

If Sunday reaches the predicted high of 102 degrees, it will be among the hottest on record for Modesto, according to Modesto Irrigation District temperature data. The top five currently are 104 degrees in 1967, 102 in 1962, and 101 in 1947, 1959 and 1993.

If it comes to pass, this will be the first triple-digit heat in the Modesto area this year. The hottest days so far were May 22-23, when the mercury reached 98.
