Not ice-breaking heat, but awfully warm for late March standards.

Of note, the average 1st 90° day in Tucson is April 9th. However, the average 1st 90° day since 2000 has arrived on March 29th.

Record heat remains in the forecast this weekend. Both Saturday and Sunday have record highs of 91° set in 1943. Tucson peaks around 93° tomorrow, with 92° expected Sunday afternoon.

A weak storm system may touch off a few showers east of the metro Monday. Another run at the 90’s is slated to arrive the middle of next week.

Spring officially arrives at 3:45 PM today. Showers may accompany the start of the new season.

A departing low pressure center triggers a few showers & storms. Favored areas for showers will be in the higher terrain. Valley floors stand a 20% chance of showers, as activity is not expected to be as numerous as the last few days. High temps reach the mid 70’s in Tucson, which is typical for late March.

Saturday features a few lingering showers near the New Mexico state line & White Mountains. Much of southern Arizona sees mostly sunny skies with highs in the upper 70’s. Temps peak in the mid 80’s Sunday.

High pressure building in next week drives the thermometer toward the mid/upper 80’s under sunny skies. A few metro neighborhoods may hit the 90° mark for the first time in 2015 Tuesday and Wednesday.

THE CLIFF NOTES

Today - Partly cloudy, breezy. 81°, east-northeast wind 10-20 MPH.

Tonight - Mostly clear. 55°, southeast wind 5-10 MPH.

Tomorrow - Mostly sunny, windy. 81°, east wind 20-30 MPH.

TODAY'S FORECAST DISCUSSION

Not as much cloud cover, but much more wind in the forecast.

An increased pressure gradient between high pressure to the north and low pressure to the south cranks up the winds. Expect east-northeast winds up to 20 MPH this afternoon with partly cloudy skies and highs in the low 80's. A few showers are possible along the international border and mountains. Strongest winds look to arrive Saturday morning & afternoon. Easterly winds gust as high as 30 MPH tomorrow, decreasing to the 20-25 MPH range Sunday and Monday. Plenty of sunshine is on tap this weekend with highs remaining in the low 80's.

After a warm start to next week, slight shower chances remain in the forecast Wednesday and Thursday. Timing and precipitation amounts remain unclear at this time.
