What a difference a week makes.

Last week was unseasonably hot. This week is cooler than usual, even for winter.

The 84 degree high temperature at the Lihue Airport tied a record for Feb. 5 set in 1991. Kahului also tied a high temperature mark with an 87 degree high and Honolulu tied a record on Feb. 2, with an 84 degree high temperature at the airport.

Today, the low temperature of 56 degrees at Lihue tied a cold weather record for the date.

The cool temperatures are expected to continue tonight and could get close to record lows overnight.

Cool dry air behind a cold front that moved over the islands this weekend caused temperatures to drop into the 50s in many places.

Honolulu Aiport recorded a low of 59 degrees. It was 51 degrees at Kalaeloa Airport in West Oahu. The low temperature at Kahului Airport was 59 degrees and Hilo was the warmest overnigth with a 61 degree low.

“It’s still going to be much cooler than normal (tonight),” said Derek Wroe, a meteorogist with the Honolulu office of the National Weather Service. “Clear, dry conditions with light winds tend to get the coolest nights.”

Tuesday night will be slightly warmer, but temperatures could still dip into the 50s in many areas.

The rest of the week will be closer to the usual winter temperatures with lows in the 60s to low 70s overnight.
