Monday's record-breaking temperatures in Hanford and Madera and record-tying temperature in Fresno are a sample of the unseasonably warm days to follow through the rest of the week.
Hanford's high temperature of 66 Monday broke the record of 61 set in 2003. Madera reported a daytime high of 64, breaking the record of 60 set in 2011.
Fresno's high of 67 tied the previous record for the date set back in 1904, said meteorologist Jim Andersen with the National Weather Service in Hanford.
Andersen said Fresno's average temperature for this time of year is 53. The Valley has been more than 10 degrees warmer than that.
Tuesday's high in Fresno is expected to hit 65 with the low dipping to 35. New Year's Day has a forecasted high of 66 and a low of 37.
Conditions will be warm and sunny with patchy morning fog in the outlying areas.
The warm weather would be producing dense fog if the Valley was getting its average amount of rain, Andersen said. Since the rainy season began July 1, the Valley has seen only 0.73 inches of rain. Normally, the rainy season produces 3 inches by now.
Meteorologists are comparing this winter to the drought winter of 1976-77. Andersen noted that the rainy season is not over, and the Valley still could see rain later this winter.
The combination of heat and high pressure is producing unhealthy air conditions. Air quality in Fresno, Madera, Tulare and Kings counties is expected to be unhealthy Tuesday. Wood burning is prohibited in all four counties.
