Area Forecast Discussion

National Weather Service - San Joaquin Valley / Hanford, CA
Issued: Tuesday, October 17 2017 - 3:35 PM PDT


SYNOPSIS...There is a slight chance of showers and thunderstorms through this evening. Little if any rainfall is expected with the main threat being dry lightning along with gusty and erratic winds. Otherwise, temperatures will remain above normal through Wednesday then trend much cooler on Thursday and Friday. There is a chance of light rain north of Fresno County Thursday night and Friday morning along with a period of increased winds. Dry conditions return this weekend with temperatures trending warmer.

DISCUSSION...Mid/high clouds continue to stream over Central CA in a southwest flow aloft. IR imagery indicating an upper level vort max of tropical origin with an area of elevated convection and embedded thunderstorms approaching the Central CA coast which will move inland later this afternoon and cross our area this evening. While the WRF is indicating no surface based CAPE and a stable airmass at the lower levels, the potential convection this evening is elevated and has the potential to produce dry lighting and downbursts containing gusty and erratic winds. This system is progged to move east of our area by Wednesday morning and give way to a day on Wednesday although there will be come high clouds streaming through at times. Meanwhile, temperatures are currently running 2-4 DEG F above yday across most of our area and guidance is indicating that Wednesday will be a few degrees warmer at most locations.

The WRF continues to advertise a strong upper trough dropping out of the Gulf of AK and approaching the PAC NW coast on Thursday. This system is progged to cross the PAC NW and Norcal on Thursday Night. The models have consistently been trending further north with the southern extent of the deeper moisture and stronger dynamics with this system with each run and the 12Z runs are limiting precipitation to areas north of Fresno County Thursday Night through Friday morning and amounts will be light as the latest QPF progs are indicating a tenth of an inch or less of liquid precipitation with snow falling as low as 8500 feet in Yosemite Park Friday morning. Some light upslope precipitation will be possible in the south end of the San Joaquin Valley and along the valley facing slopes of the Tehachapi Mountains on Friday as the flow turns northwest on the back side of the trough. The main impacts that this system will have for our area will be a period of increased winds on Thursday Night and Friday in downslope favored areas and a sharp cooling trend with daytime temperatures expected to lower by 12-20 DEG F between Wednesday and Friday.

The medium range models and their ensemble means remain in fairly good agreement with strong high pressure building into CA this weekend and strengthening over the region through the middle of next week. This will result in a period of dry weather mainly clear skies and a gradual warming trend each day with temperatures expected to approach seasonal normals by Sunday and rise to above normal levels from Monday onward.

AVIATION...Areas of MVFR visibilities due to smoke can be expected in the San Joaquin Valley, southern Sierra foothills and higher elevations of the southern Sierra Nevada for at least the next 24 hours, with VFR conditions prevailing elsewhere across the Central California Interior. Isolated thunderstorms possible in the San Joaquin Valley, foothills, Sierra Nevada, and Kern County Mountains through 08Z Wednesday.

AIR QUALITY ISSUES...On Wednesday October 18 2017... Unhealthy for sensitive groups in Kern County. Further information is available at Valleyair.org
