Thursday’s springtime storm system brought some light but much-needed rain to parts of San Diego County and icy conditions to our mountains. But now, just like that, a weekend warm-up is on the way.

NBC 7 meteorologist Sheena Parveen said light, passing sprinkles would linger into Friday morning but, by lunchtime, most of the county should be dry and the clouds would be gradually clearing.

In the afternoon, expect sunshine – a sign of what’s to come.

“The weekend will be sunny with an offshore flow, which will warm us up,” Parveen explained.

The temperatures will start slowly warming up on Saturday. By Sunday, Parveen said it’ll be unseasonably warm in our region – with high temps around 10 to 15 degrees above normal.

According to NBC 7’s First Alert Forecast, it’ll be around 87 degrees in the inland areas on Sunday and at the coast, 77 degrees.

“That looks like beach weather,” Parveen said. “The normal high this time of the year at the coast is more like the mid to upper-60s.”

The trend looks like it’ll continue into next week, with another warm-up by mid-week that’ll bring a “dry spell” to the county. Parveen said that means the weather will be warm and sunny for the San Diego Padres Home Opener at Petco Park on April 1, too.

Icy Roads in San Diego's Mountains

Thursday’s storm, at times, also created some snow flurries in the mountains, which led to icy road conditions.

The San Diego County Office of Education said that due to the icy conditions, the Julian School District would shift into distance learning mode for all students Friday.
