AREA FORECAST DISCUSSION

NATIONAL WEATHER SERVICE - San Joaquin Valley / Hanford, CA
Issued: Saturday, February 4 2012 - 9:30 PM PST

Synopsis... Weak high pressure and mostly clear skies will prevail throughout the region for the rest of this weekend. Clouds will begin to increase on Monday...and then rain and mountain snow are possible throughout the region Tuesday due to an approaching low pressure system. Dry conditions are then expected for the rest of next week as high pressure returns.

Discussion... A high pressure ridge continues to provide dry and clear coditions across the Central California interior. The sunny skies and moderate offshore flow this afternoon allowed for another mild day with temperatures in the valley reaching the upper 60s and lower 70s. Current 24 hr temperature trends are generally running plus or minus a degree or so. Expect similar overnight lows tonight with just some patchy frost in the valley again...still too dry for significant fog development. Dry and unseasonably mild conditions are on track to continue for the next few days ahead of a developing low pressure system...which is still progged to bring cooler conditions and some precipitation chances to our area by Tuesday. No update is planned for the current forecast this evening.

Prev discussion... /issued 251 PM PST Sat Feb 4 2012/

Discussion... Blocking high pattern remaining the dominate feature over the west today. With this...will expect little change in the next 24 hours as dry conditions continue. Will see another night of cool min temp/s as a dry atmosphere remains situated over the district. This little change in the atmosphere will see also allow for a continuation of the offshore wind flow. This flow allowed temperatures to warm up today...especially over Kern county...and the valley reached well into the 60s. Sunday will see similar conditions as the strong ridge of high pressure remains over the west. The little change in the pattern will also allow for one more night of strong downsloping winds near the Grapevine supported by the offshore wind flow. Models show the flow becoming onshore early next week as the storm approaches the West Coast.

By Sunday...short range models show a storm system pushing the blocking high more toward the Rockies later on Monday. This storm...currently dropping from the gulf of Alaska...is timed to hit the West Coast on around Tuesday. Longer range models seem to have a good handle on the timing of the trof expected on Tuesday. Therefore...will maintain the current wording of a chance of precip on Tuesday with diminishing potential toward Tuesday night. Models also show this system as a progressive system and expected to exit the region by early Wednesday. Models also indicate this system may split with most it its energy traveling south into Southern California. Therefore...will maintain low precip amounts during the storm as uncertainty remains high on how much precip will hit the district. Models then show the disturbance exiting the region on Wednesday as a short wave ridge travels through the west. While models do show another storm system attempting the approach next weekend...will hold off on any precip wording until better consensus can be reached.

Aviation... Vfr conditions will prevail across the Central California interior through 06z Monday.

Air quality issues... None.

HNX watches/warnings/advisories... None.
