SLOweather

As some of you have noticed, the PG&E Community site is reporting erroneous readings. This is due to the theft of the radio transmitter board from their station.

John Lindsey is working on getting the station repaired or replaced.

Last night (Tuesday) was about the coolest of the season here at SLOweather, with the temperature dropping below 48°F at 5AM PDT.

Higher daytime temperatures are on the way, though. The NWS is forecasting highs in the high 90s to over 100 for SLO Thursday through Saturday.

An upper-level low centered about 200 miles to the southwest of San Luis Obispo combined with an area of high pressure over the desert southwest has been pulling a significant amount of subtropical moisture from Mexico towards our area.

Currently, most of the moisture will be confined to the mid and upper-levels of the atmosphere creating the potential for dry  lightening strikes and localized gusty winds in the higher elevations
 of San Luis Obispo County this evening through Saturday.  

As the atmosphere moistens on Saturday, the potential for rain showers will increase, mainly in the eastern part of San Luis Obispo county. Nevertheless, a chance for an isolated thunderstorm or rain shower could also occur along our coastal areas as well. I suspect that most the moisture will fall as virga (precipitation evaporating before reaching the ground).

If we receive any rain, it will be a hit or miss variety with many areas not receiving any precipitation at all.

The subtropical cloudiness will also keep the overnight temperatures warmer tonight and tomorrow night and will increase the humidity levels making it feel more like southern United States than San Luis Obispo. This condition will also keep the coastal low clouds to a minimum.
 

The upper-level low will weaken and move eastward on Sunday with the return back to a typical late-summer pattern with morning clouds burning back to the beaches by the afternoon.  This pattern will continue into next week with temperatures generally running near to slightly below average.
