Area Forecast Discussion National Weather Service Hanford CA 301 PM PST Thu Mar 4 2021

SYNOPSIS. A quick moving system will bring a chance of light precipitation to the region from Friday night into Saturday morning, primarily north of Fresno county. There is increasing confidence for a return of wet weather and cooler than average temperatures for next week.

DISCUSSION. It was a clear, chilly start across the district this morning as low temperatures bottomed out between 2 to 6 degrees below average for early March. A shortwave ridge moving through the region has allowed for temperatures to warm well into the 60s to near 70 in the valley and Kern desert, much warmer compared to yesterday. Friday morning lows will be a near carbon copy of this morning with continued slightly below average low temperatures for the lower elevations of the valley and Kern county desert.

For Friday, the 500mb HREF analysis indicates that the aforementioned ridge will move eastward into the central Rockies. One last day under this ridge will allow for afternoon high temperatures to reach between 4 to 10 degrees above average across the central California interior. As we progress from Friday evening into Saturday morning, the HREF as well as lower resolution ensembles (EPS/GEFS/CMCE) indicate that a much advertised shortwave trough will reach the NorCal coast. The ensembles then quickly move this trough through NorCal into the northern Rockies by Saturday afternoon. As has been the case for most of the winter, the best moisture and dynamics in this system will remain well to our north. There will be enough orographical lift to generate some light rain and snow showers in the Sierra Nevada, primarily all north of Fresno county. Scattered light showers can not be ruled out in the valley, especially into Merced and Madera counties. Given how quick this system is moving through the region, the time frame for the best chances of precip is short, and will mostly occur from overnight Friday through Saturday morning. A faster moving system also means lower QPF amounts from prior guidance, with most areas seeing less than 0.10". A few areas in the Yosemite area may see between 0.25" to 0.5", with 2" to 4" of snow in the highest elevations. The corresponding probabilities of reaching certain accumulation thresholds is given in the Certainty section below. Bottom line, don't expect any soaking rains across a majority of the district.

A big change is in store for next week. We'll see a return to a wet pattern with below average temperatures. The mean 500mb heights from both the NAEFS, and ECMWF ENS show a deep trough setting up over the western US from Monday trough at least Wednesday. At this time, there is higher confidence into lower than average temperatures. The chances of precipitation during this time frame is also increasing, however it is still too far off to pin down exact amounts and specific timing. Cold temperatures also mean a chance of snowfall down to pass levels in Kern County. More details in the coming days!

AVIATION. VFR conditions can be expected over the central California interior for at least the next 24 hours.

AIR QUALITY ISSUES. None.
