Area Discussion for - Sacramento, CA

      (on/off)   Help   NOTE: mouseover dotted underlined text for definition

Fxus66 ksto 221000 afdsto area forecast discussion national weather service sacramento ca 300 am pdt Tue oct 22 2019 Synopsis Breezy conditions at times, especially Wednesday into Thursday when elevated fire weather concerns are expected. Dry conditions with above average temperatures forecast through the remainder of the week. Discussion Broad ridge over the eastern pacific and norcal continues to provide clear skies. Current temperatures range from the upper 20s in the mountain valleys to the mid 60s across milder portions of the central valley and foothill thermal belts. North to northeast pressure gradients are a bit tighter compared to early Monday resulting in gusts in the 15-25 mph range across the northern sacramento valley and local gusts of 20-40 mph in the foothills of butte county. Warm and dry weather will continue this week with highs forecast to be around 5 to 15 degrees above average. Overnight lows will be mild across windier portions of the valley and in the foothills thermal belts, but will be close to normal elsewhere. The main concern this week is enhanced fire weather conditions, especially for Wednesday and Thursday, as the short-wave presently moving through southern bc digs into the central us. As this happens, the upstream ridge is forecast to amplify along 130w providing a little better upper level support to the tightening north northeast surface gradients. Lighter winds forecast to return later Thursday and continue Friday as the ridge moves overhead. Extended discussion (Saturday through Tuesday) Models in good agreement in dropping an upper trough out of western canada and into the northern great basin on Saturday. Impacts on Saturday will be minimal. There should be a little

cooling but daytime highs Saturday are still likely to come in several degrees above normal. Models continue diverged going into early next week with a fairly significant difference in impacts depending on solution. ECMWF continues to dig the upper trough southward into the central great basin Sunday while the GFS tracks the trough much farther east into the central u.S. During this same timeframe. ECMWF solution would bring another round of strong northerly winds to most of the CWA while the GFS solution would leave norcal under light gradients and lighter north winds. Either way, daytime temperatures cool behind the trough with daytime highs dropping to near normal on Sunday. Leaning towards a middle of the road approach to the winds Sunday and have gone with relatively light north winds. Continued northerly flow will bring a little more cooling on Monday with daytime highs dropping to slightly below normal. Upper ridge slides over the west coast next Tuesday bringing a slight warm up. Aviation Vfr conditions the next 24 hours at TAF sites. Generally northerly sustained winds 5 to 15 knots. Sto watches warnings advisories Fire weather watch from late tonight through Thursday afternoon for carquinez strait and delta-central sacramento valley in glenn, colusa, yuba, northern sutter, and butte county below 1000 ft-eastern mendocino nf-eastern portion of shasta trinity nf-lake county portion of lake-napa-sonoma unit-northern motherlode from 1000 to 3000 ft.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
