12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

UPDATE. Added thunderstorms through this afternoon for San Joaquin Valley through this afternoon south of Madera County and West Side Hills.
PREV DISCUSSION. /issued 358 AM PDT Thu Aug 13 2020/
SYNOPSIS . A northward influx of tropical moisture associated with the remnants of Elida will bring a threat of isolated thunderstorms to parts of the central California interior through this evening. Otherwise, dry weather will prevail during the next several days. Extremely hot temperatures can be expected Friday through Tuesday and possibly longer as a strong ridge of high pressure builds into the Golden State.
DISCUSSION . Tropical moisture is on its way northward early this morning. Its arrival into Kern county, as well as the southern San Joaquin Valley, will be accompanied by some showers along with perhaps some lightning and thunder. Doppler radars across southern California at this hour detect light to moderate precipitation over the coastal waters. The moisture is associated with the remnants of what was once Hurricane Elida. No doubt the cloudiness it brings will throw a monkey wrench into high temperatures over parts of the central California interior today. On the positive side, cloudiness will keep high temperatures below the century mark in parts of the valley and the desert today. On the negative side, any lightning strikes could spark new fires over our parched landscape. And then there's the humidity factor. The northward influx of tropical moisture will certainly bring a muggy feel to the air during the next 24 to 48 hours. It would not be a surprise if dewpoint temperatures reach 70 degrees or higher in some San Joaquin Valley locations during the short term periods. The best chance of measurable rain and thunderstorms will occur over the mountains and even include the coastal ranges west of I-5.
In the broader picture, this tropical moisture is being channeled northward between a weak area of low pressure over the Eastern Pacific and a strong upper level ridge of high pressure centered near the Arizona-New Mexico border. The models bring the primary slug of tropical moisture northward through midday. A second northward surge of tropical moisture is forecast to move into central California later today into tonight and linger through at least midday Friday. By Friday afternoon, the models aggressively build the upper level ridge westward into southern and central California. As this ridge builds into the Golden State, much of this tropical moisture will probably evaporate. So Friday should turn out to be a sunnier day over much of the CWA, and definitely hotter. Nonetheless, there may still be enough mid level moisture lurking to trigger isolated afternoon thunderstorms near the Sierra crest Friday.
Otherwise, this high pressure ridge means business. It's going to play a huge role in our pattern by this weekend and for much of next week as it amplifies and parks itself over the Great Basin. Regretfully, this strong high pressure ridge will bring a vicious and relentless spell of blistering heat for many many days beginning Friday. The extreme heat will elevate the fire danger over the higher elevations and air quality will likely worsen in the San Joaquin Valley with time. High temperatures could challenge records in some locations from Saturday through Monday, despite some high clouds. (Record highs for Fresno and Bakersfield have been provided below this discussion for easy reference.) The Excessive Heat Watch was upgraded to an Excessive Heat Warning accordingly for the West Side Hills, San Joaquin Valley and lower foothills as well as the Kern County desert for this period.
This high pressure ridge will not likely budge for many days, so it's possible that the Excessive Heat Warning might have to be extended into the middle of next week. Minimum temperatures will also be quite warm in this pattern with thermometer readings staying above 80 degrees in the urban areas of the valley and in parts of the Kern county desert.
Although the strength of this ridge will minimize or cap afternoon convection over the Sierra, a pop up thunderstorm or two cannot be ruled out any afternoon near the crest from Saturday through Tuesday. Additionally, please think twice if you want to seek cooling relief in any of the rivers. The rivers have proven many times over already this year that they are potentially dangerous places. Their cold, swift currents have carried a number of swimmers to their death and there've been far more numerous water rescues of the lucky ones who've survived the river's swift waters. Please don't become a sad statistic. Stay cool in an air conditioned home during this upcoming heat wave. If you have to be outdoors, stay out of the sun, especially during the hottest time of the day, slather on the sunscreen, wear a protective hat and light colored, loose-fitting clothing.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
