Area Forecast Discussion National Weather Service Hanford CA 108 PM PST Mon Mar 1 2021
SYNOPSIS. A couple of weather systems will affect parts of the Central California Interior. The first will move across Southern California on Wednesday bringing some light precipitation to the Kern County Mountains and Desert. The weather will return to dry with high pressure building on Thursday and Friday however another storm system will arrive on Saturday and will likely affect areas to the north of Kern County.
DISCUSSION. Crystal clear skies over the forecast area this first afternoon of March and this pretty much sums up the weather pattern for much of the wet season thus far. As anticipated, the precipitation amounts for February can be best summed up as dismal, especially for areas south of Fresno. Hanford and Bakersfield both endured the 4th driest February on record while Fresno fared a bit better with its 17th driest February.
As for the pattern, the area will be visited by two systems over the next week. The first, a southern track feature now located out near 35N/135W is progged to move into the Point Conception area on Tuesday afternoon and cross Southern California on Tuesday night and Wednesday, bringing a threat of light precipitation as far north as Kern County however the main precipitation threat will remain to the south. Ensemble modeling probabilities show that there is a 16 percent chance of 0.01" of rain at Edwards, thus I wouldn't count and a big rain event for sure.
The second weather system continues to show good consistency between today's operational GFS and ECMWF models when compared to ensembles. Given this, there is some increasing confidence that by the time this system arrives on Saturday, the Merced area has a 36% probability of receiving 0.10" of rain and a 42% probability of getting at least 0.01". Over the Sierra probabilities are higher thus this system seems like the next precipitation weather maker (albeit light) over much of the forecast area.
After this weekend, the overall model trending is to bring a deepening low pressure area over the West and by Tuesday and Wednesday dropping a closed low over California which could bring some much needed rain and snow. This will need to be monitored as this would be very good news for this very dry year.
AVIATION. VFR conditions will prevail across Central California through at least 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 medium.
There is a 25% probability of 0.10" of rain and a 38% probability of 0.01" for Fresno on Saturday.
Certainty levels include low . medium . and high. Please visit www.weather.gov/hnx/certainty.html for additional information an/or to provide feedback.
