Clear skies, offshore flow and a cold airmass produced freezing temperatures throughout the Central Coast this morning and another round will happen tonight.
Paso Robles reached a low of 21 degrees, while San Luis Obispo saw a low of 27 degrees. Both of these readings are record breaking lows. The record low on February 4 at the Paso Robles Airport was 23 degrees set in 1955. The previous low in San Luis Obispo was 30 degrees also set back in 1955.
The recovery from the cold was actually pretty good with upper-50s and low 60s, I think we'll see similar lows tonight and highs on Wednesday.
High pressure is rebuilding with winds during the night and morning hours pushing offshore and then shifting out of the northwest during the afternoon. Temperatures will slowly improve over the rest of the week.
The big question in the forecast is about rain opportunities next week. There looks to be a deep trough in the region Monday and Tuesday but the track of the surface low would be inside the Sierra which would limit rain amounts. I think some light rain Sunday or Monday is a decent bet however looks very light.
