UPDATE. Updated for 00Z aviation discussion

AVIATION. 00Z TAF discussion:

VFR conditions will continue ahead of an area of rainfall pushing into the area. This widespread rain will continue to spread east across the region through the overnight hours and will last through the remainder of the TAF period. Visibilities will gradually reduce to MVFR/IFR with ceilings also lowering. Widespread IFR/LIFR ceilings are expected by the mid to late morning hours. Southeast winds will be generally light overnight before increasing to around 10kts through the morning tomorrow. /TW/

DISCUSSION. Today and Tomorrow:

High clouds continue to filter over the region today, keeping temperatures cool despite the increased southerly flow. Temperatures have warmed into the 40s to low 50s areawide as an area of rainfall is edging into the CWA from the west this afternoon, associated with an approaching mid-level trough. This morning's sounding indicated a very dry low-level atmosphere over JAN. As the trough progresses eastward, it will need to saturate these lower levels in order for the rainfall to reach the ground. Per ground observations in northeast LA, this has already occurred with dewpoints increasing into the upper 20s and reports of light rainfall at the surface.

This system will progress eastward tonight and continue to erode the dry layer of the atmosphere. Light to moderate rain showers will spread throughout the area by Thursday morning. Temperatures will drop overnight back into the 30s. With the increased moisture around though, temperatures are expected to remain above freezing, generally in the mid to upper 30s. As the front edge of the precip shield tracks eastward overnight, wet bulb profiles will be hovering in the low-mid 30s within the deep low-level dry air and evaporational cooling will be underway along that edge. There remains a very small chance that some sleet could fall in our northern counties between midnight and daybreak Thursday. Mention of this was kept out of the weather grids since the chance is so low, but it bears mentioning here that a few ice pellets or flurries ahead of the main rain shield cannot be ruled out and no impacts are expected.

As Thursday progresses, the rain shield will continue its shift eastward. With the aid of the southerly flow, temperatures will warm into the mid 40s in the north and the mid/upper 50s in the south. Expected rain totals are between a half inch and 1.5 inches, with the heavier amounts expected in the Delta. /10/

Thursday night through next Tuesday night:

Rain will be moving out of the region Thursday night into Friday morning as the frontal system moves through the region, with drier air filtering in on Friday. Some gusty northwest winds will be possible in the wake of the frontal system on Friday. Highs Friday will mainly be in the 50s.

Expect dry conditions to continue on Saturday as high pressure remains in control across the region. Highs will be a little bit warmer, ranging from the 50s to around 60 south. Light rain chances will return to the region on Sunday as a shortwave trough digs through the region. Highs once again will be in the 50s to around 60 south. Expect drying & warming conditions into early next week, with highs Monday and Tuesday in the 60s for most locations. Rain chances will return to the region Tuesday night as the next frontal system approaches the region. /27/

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 numerous 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.
