Synopsis
Scattered showers will change to snow tonight followed by more
seasonal weather through the middle of the week.

Near term until 6 am Wednesday morning
Updated to add patchy drizzle freezing drizzle to the forecast
through 06z or so, as model soundings show most of the moisture
will reside below the -10c level for several more hours. Lower
levels should eventually cool sufficiently to introduce ice
crystals and turn precip over to mostly snow overnight.

Previous discussion...

cooling aloft will result in rain changing over snow during the
evening but accumulation potential is minimal..Limited to an
inch or so for areas north of I 80... Slightly more along the
ridges.

Winds will remain gusty with a tight pressure gradient and forecast
soundings indicating that winds should remain coupled
overnight.

Short term 6 am Wednesday morning through Friday
Cold northwesterly flow is expected to maintain snow chances in
lee of the lakes and in the higher terrain through Wednesday,
but conditions thereafter will be of improvement as building
high pressure drys and warms the weather in advance of another
wrn CONUS trough.

Long term Friday night through Tuesday
The advance and passage of the aforementioned trough is timed to
degrade conditions via rain for the weekend, and cool temperature
back toward the average for the start of the new week.

Aviation 02z Wednesday through Sunday
Low-endVFR or MVFR ceilings will dominate through the taf
period. Rain showers will turn over to snow showers and flurries
with time, most numerous north of i-80. Brief visibility
restrictions are possible here. Gusty wsw winds of up to 20 to
30 knots will continue through much of the night, before
settling into more of a westerly direction with time and
diminishing somewhat on Wednesday.

Outlook
Restrictions are possible until high pressure builds Wed night.

Restriction potential returns with a Sat cold front.

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.
