The month of April is certainly living up to it’s reputation as
a transitory month between the cool, wet and blustery weather of
winter and the warm and dry weather of summer.
Areas of fog will burn off later this morning. Cool and unstable
air in the wake of yesterday’s cold front may produce rain showers
this afternoon, with the highest likelihood across the coastal
mountains. This precipitation may be the last for this rain season.
Otherwise, cool, windy and partly cloudy weather will continue
through Friday.
A 1034 millibar high, currently about 1,00o miles west of San Luis
Obispo, will move eastward towards the west coast. This condition
will produce a steep pressure gradient along the California
coastline. This pressure gradient will give fresh to strong
(19 to 31 mph) northwesterly winds today.
High temperature reading’s will be well below normal for the end
of April, only reaching the high 50s to the low 60s throughout our
area today through Friday. Overnight lows will mostly be in the
40s.
As this 1034 millibar high moves closer to the west coast, it
will produce moderate gale to fresh gale force (32 to 46 mph)
northwesterly winds with gust hitting 50 mph along the coastline
on Thursday into Friday.
The northwesterly winds will decrease and temperatures will warm
on Saturday.
A fairly strong ridge of high pressure will move over California on
Sunday producing gentle northeasterly (offshore) winds and spectacular
summer-like weather.
Even warmer weather will develop on Monday and Tuesday, with Paso
Robles reaching nearly 90 degrees by Tuesday. Temperatures should
fall back to near seasonal normal’s later next week as the
northwesterly (onshore) winds pick-up again.
