Weathernotes for Wednesday, July 6, 2001

There was rain on the roof last night, and this morning the streets were wet and the windshield wipers convenient, if not required.

A very moist monsoonal flow is resulting in widespread, scattered showers in Southern California. A chance of showers is forecast through Saturday morning.

In the coastal areas and valleys QPFs are generally expected to be light, but HPC forecasts show a bull's-eye of over 1.0 inch of precipitation in the central Sierra and a thundershower could occur just about anywhere in Southern California with the possibility of strong winds and moderate to heavy rain.

Weathernotes for Wednesday, July 4, 2001

This morning skies were mostly cloudy around the L.A. basin, the result of a moist southeasterly flow. A few sprinkles fell on climbers at Stoney Point in the northwest San Fernando Valley. With strong negative LIs and large CAPE, the atmosphere was primed for convection, but the thick mid-level clouds limited development.

This afternoon the band of clouds has continued it westward movement and much of the area is now seeing more insolation. Two large cells can be seen developing over the Southern Sierra in this visible satellite photo taken at about 1:15 PDT. Additional development appears to be occurring over the San Gabriels and near Mt. San Jacinto.

Sometimes it's hard to appreciate the size of cloud features on satellite photos. The circled specks on this visible satellite photo, from the afternoon of April 9, were sizable cumulonimbus cells when viewed from the ground.
