Short term Today through Wednesday... A progression of low
pressure systems through the western us will keep unsettled
weather over the region. The first system will move into northern
ca today, increasing precipitation coverage across southeast
oregon and much of southwest idaho. By afternoon weak instability
and upper dynamics will support isolated thunderstorm development
over southwest idaho and east-central oregon. Brief heavy rain and
wind gusts to 35 mph will are possible with the storms. The low
center tracks into the great basin by Monday putting the focus of
precipitation development over central and southwest idaho.

Afternoon thunderstorms are again possible over the higher terrain
of central. By Monday night a second low is approaching the
oregon coast as the first low exits eastward. The second low will
follow a similar track into the northern great basin where it will
stall, keeping widespread precipitation over the region through
Wednesday. Widespread precipitation totals of 0.50-1.00 inch are
expected through Wednesday with banded precipitation along the
periphery of the closed lows, and convective activity leading to
locally higher totals. Snow levels will fluctuate between 6-8k
feet as the cold core lows pass through and temperatures will run
10-15 degrees below normal.

Long term Wednesday night through Saturday... Active weather
pattern will continue through the extended period as several low
pressure systems move across the intermountain west. Showers will
continue Wednesday night through Thursday as low remains over the
northern rocky mountains. The low pressure system splits on Friday
and one piece exits to the northeast while the remaining energy
drops to the south. A low pressure system closes over central
california on Saturday continuing the chances for showers and
thunderstorms through the holiday weekend. Temperatures will
remain 10-15 degrees below normal through the period while snow
levels will hover around 6500-7500 ft msl.

Aviation LowVFR-MVFR conditions in rain showers today.

Isolated thunderstorms will develop this afternoon. Snow levels
6k-7k ft msl. Surface winds se-sw 10 kts or less, becoming w-nw
10-15 kts this afternoon. Winds aloft at 10k ft msl SE 10-20 kts.

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.
