Friday forecast for Austin: Happy Friday! It's going to be one for the record books, forecasters say.

Temperatures in Austin could set a new daily heat record and hit 86 degrees, courtesy of warm west and southwest winds that are fending off moisture from the south and winter air from the north, the National Weather Service said. So is it May already? It will definitely feel like it because that's when Austin temperatures normally max out at 86 degrees.

A high of 86 would eclipse the previous record for Austin temperatures on Feb. 15, when the mercury hit 85 degrees in 1980. The normal daytime high for this time of year is about 20 degrees cooler.

Beyond the record heat, forecasters expect mostly sunny skies in the city with southwest winds of 5 to 10 mph. More clouds are likely in the evening as temperatures sink to an overnight low of 50 degrees.

Runners preparing for Sunday's Austin Marathon can look forward to a mild weekend with sunshine and light winds, the weather service said. Saturday should be mostly sunny with a high near 71. The night before the big race will be partly cloudy but temperatures should stay above 55 degrees.

On race day, expect sunshine and a daytime high near 69 degrees. Northwest winds of 5 to 10 mph will shift to north-northeast in the afternoon. Sunday evening will see partly cloudy skies and temperatures slip to as low as 47 amid north-northeast winds of 10 mph, forecasters said.

Rain chances and colder wintry temperatures return in the weather service's extended forecast for next week:

Monday: A 20 percent chance of showers with a high near 57. Then a 30 percent chance of showers at night with a low around 43. North-northeast winds of 10 to 15 mph.

Tuesday: A 40 percent chance of showers with a high near 49. At night, rain chances slip to 30 percent with a low around 40.

Wednesday: Partly sunny with a high near 56. A 20 percent chance of showers returns at night with a low around 42.
