Subtropical moisture

Sunday, July 11th, 2010
 

Subtropical moisture interacting with an upper-level low about

200 miles southwest of San Luis Obispo produced a few rain

showers and thunderstorms this morning. Most areas along the

coastline did not receive any rain.

6 hour Rainfall totals:

SLO Water Reclamation Facility …………… 0.01″

Santa Margarita Fire Dept ……………….. 0.05″

SLOWeather.com …………………………. 0.03″

San Luis Obispo County-Mc Chesney Field …… 0.03″

Atascadero …………………………….. 0.08″

Paul’s house (41 W. & Toro Cr.) ………….. 0.10″

Arroyo Grande ………………………….. 0.03″

Paso Robles Municipal Airport ……………. 0.02″

This morning’s showers are currently moving northeastward out

of our area. However, a band of thunderstorms is currently

moving northeastward through Santa Barbara County towards

the southeastern part of San Luis Obispo County.

This subtropical moisture will continue to produce variable mid

to high-level clouds and humid and muggy conditions. As we head

into the afternoon, the chance of rain showers or thunderstorms

will increase over San Luis Obispo County. The highest chance

of this occurring is mainly over eastern regions of the county.

Note: These possible thunderstorms could produce lightning

strikes, however the storms will also be accompanied by

rain and thus the threat of lightning sparked wildfires

is expected to be small.

Along the coastline the subtropical moisture will help to

partially mix out the marine layer, leaving behind partly

cloudy conditions with periods of sunshine.

Today’s temperatures will range from the high 80 to low 90s

in the interior. The coastal valleys will mostly be in the mid-70s

and temperatures along the coastline will in the 60s.

Tomorrow will bring typical July weather with the usual contrast

of seasonably warm temperatures inland, with cool and foggy

conditions at the coast.

Strong high pressure is predicted to build over California later

in the week bringing a significant warm-up with inland temperatures

reaching 105 degree by the end of the week. Temperatures in the

coastal valleys will warm to the mid-80s.

Increasing northwesterly winds will produce a greater amount of

clearing and much warmer temperatures along the beaches, especially

the southwesterly facing (Avila Beach and Cayucos) beaches, where

temperatures may reach the high 70s to low 80s by Friday.

WeatherElement sites back!

Monday, May 17th, 2010

Islay Hill, the SLO Water Reclamation Facility, PG&E Energy Education Center, Condor Lookout, and the Santa Margarita Fire Department are all back on-line! There is still work to do on the individual sites, but the data is current.

IF YOU HAD THEM BOOKMARKED, the URLs have changed to shorter, cleaner ones. Please use the new URLs as linked to on the SLOweather home page.

Variance in rainfall totals throughout the county

Wednesday, April 28th, 2010

Yesterday’s cold front produced a fair amount of variance in
rainfall totals throughout the county. A few areas only received
a trace while other locations recorded more than half of an inch.

The 24 hour rainfall totals as of 7 a.m.:

Paso Robles Airport ……………………………. 0.01″
Arroyo Grande …………………………………. 0.06″
Atascadero ……………………………………. 0.28″
Santa Margarita ……………………………….. 0.12″
Paul’s house-Hwy 41 & Toro Creek ………………… 0.60″
Camp San Luis …………………………………. 0.16″
Nipomo East (Dave’s house) ……………………… 0.12″
Diablo Canyon …………………………………. 0.13″
PG&E Energy Education Center, Avila Valley ……….. 0.26″
San Luis Obispo Airport ………………………… 0.03″
SLOWeather.com ………………………………… 0.13″
Los Osos ……………………………………… Trace
Cambria ………………………………………. 0.12″
Cottontail Creek ………………………………. 0.40″
Rocky Butte …………………………………… 0.75″

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.

Full Snow Moon Sunday, 28 Feb 2010

Saturday, February 27th, 2010

Sunday’s February full moon becomes full at 8:40 AM PST. It sets at 6:17 AM, and rises at 6:26 PM PST. Itwas known by the Native Americans as the Snow Moon, Hunger Moon, or Storm Moon. With the weather we’ve had lately,  Storm Moon is pretty close. From the storm start Friday evening through Saturday evening, SLOweather received  3.54″ of rain! WeatherElement stations east of us received lesser total precip amounts. The SLO Water Reclamation Facility 2 miles away received 1.87″, and the Islay Hill neighborhood got 1.26″. This shows how important the Irish Hills are to orographic enhancement of the local rainfall.

Also, SLOweather had pea-sized hail and a few peals of thunder Saturday morning. The local creeks are raging. It’s nice to hear the sound of Prefumo Creek down in the canyon.

Heavy rain and hail, 8:06 am 27 Feb 2010

Saturday, February 27th, 2010

SLOweather just had a small cell pass over us, with pea sized hail and heavy rain. I saw a peak rain rate of 4.06″ per hour for a short time.
