Area Forecast Discussion National Weather Service Hanford CA 239 PM PDT Sun Mar 29 2020
SYNOPSIS. Dry weather returns to the area on Monday and will prevail throughout the week. A warming trend will result in near normal temperatures on Monday and above normal the rest of the week. Parts of the San Joaquin Valley and Kern County Desert are forecast to climb into the lower 80s by the upcoming weekend.
DISCUSSION. A weak shortwave trough is tracking inland across central California and producing scattered showers, mainly over the higher terrain. As the upper low tracks overhead, we could even see a thunderstorm by later this afternoon. This activity is progged to end this evening as the upper trough continues to move east away from the area.
Behind the exiting trough we will see some gusty winds over the ridges and through and below mountain passes through the evening hours. We'll also experience some seasonably cool overnight lows tonight, with temperatures mostly bottoming out at or just slightly below normal.
Models handle the next few days of our forecast pretty similarly, but by the second half of the week there are some significant differences. There is agreement in tracking an upper low inland through western Canada Monday and swinging a weak lobe across the US Pac NW Tuesday into Wednesday. This will result in a weakly cyclonic west to northwest flow across central California, producing dry conditions with moderately warming temperatures through midweek. Through Wednesday we can expect high temperatures to hover right around climo.
For the end of the week and next weekend the model differences begin to impact our forecast certainty. The deterministic GFS solution is quick to open up a Pacific low pressure system and swing it across northern California by Friday, while the ECMWF holds off til Saturday with a deeper slower trough. Differences continue into Sunday, as the ECMWF drops a wound up low southward offshore the US west coast, while the GFS essentially absorbs the feature into the upper low over Canada. The differences in the evolution of these synoptic features will have an effect on our temperatures and whether we will have a chance for some precip over northern portions of our area by the upcoming weekend. Current blended model guidance is staying dry through the period with a continued modest warmup. Again, forecast certainty for the Friday through Sunday timeframe is low, but for now we are going with a dry forecast, with high temperatures reaching as much as 4-8 degrees above normal by Sunday.
AVIATION. MVFR to IFR ceilings and visiblities in isolated showers across the San Joaquin Valley, primarily north of Kern County, through 01Z Monday. IFR conditions and mountain obscuration in low clouds and showers for the Sierra Nevada and Kern County mountains through 03Z Monday. Wind gusts up to 40 kts possible in the Kern County mountains and desert through 08Z Monday. VFR conditions will otherwise prevail over the central CA interior for the next 24 hours.
AIR QUALITY ISSUES. None.
The level of certainty for days 1 and 2 is high. The level of certainty for days 3 through 7 is low.
Certainty levels include low . medium . and high. Please visit www.weather.gov/hnx/certainty.html for additional information an/or to provide feedback.

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.
