MOST ACCURATE FORECAST: Relief from this March heat on the way!

Posted
and last updated

PHOENIX — Arizona is in the middle of a record-breaking March heat wave.

In Phoenix, we've already broken three records, including daily high temperature records Monday and Tuesday and a new record warm low temperature on Tuesday morning.

There's still a chance we could add a fourth record early Wednesday morning before temperatures start to drop.

The current record warm low is 66 degrees set in 1990. Phoenix is likely to only drop into the upper 60s overnight.

With incoming clouds, afternoon temperatures will be a few degrees lower and that will keep us out of record territory on Wednesday afternoon.

Wednesday's record of 100 degrees is the earliest we've ever seen triple-digit heat in Phoenix. That record was set in 1988.

Valley temperatures will reach the mid 90s on Wednesday and Thursday before falling back into the 80s as we head into the weekend.

Our Valley forecast looks dry, but with the increasing clouds on Wednesday we may see a few spotty showers in parts of the high country. Watch out for gusty winds and isolated lightning strikes, too.

Breezy to windy conditions will be in the forecast Thursday through Saturday as another storm system passes to our north.

Right now, it's not looking like we'll see any rain or snow in Arizona, but we will get a nice cool-down heading into the weekend.

Expect partly cloudy skies and highs in the low to mid 80s across the Valley on Saturday and Sunday.
