Synopsis
Issued at 1240 pm est Wed jan 17 2018
drier and warmer conditions will dominate the remainder of the
week into Saturday, before rain chances return. Afternoon highs
today will reach the upper teens to lower 20s. Highs by the
weekend will climb into the 40s.

Short term (this evening through Thursday)
issued at 225 pm est Wed jan 17 2018
quiet weather in the short term as dome of high pressure builds into
the area. Recent snow pack has kept temperatures cool this
afternoon despite plentiful sunshine. Winds overnight will slow
down the radiational cooling tonight and should keep temperatures
in the teens tonight and then warm air advections tomorrow warming
to near 30s.

Long term (Thursday night through Wednesday)
issued at 225 pm est Wed jan 17 2018
warming trend into the weekend with a west southwest flow bringing
warm moist air into the area. Temps into the 40s this weekend with
dew points in the upper 30s should melt the recent snow pack across
the cwa. Bumped temps up slightly Sat and Sun to account for strong
southerly flow.

Wave of energy still off the pacific coast moves onshore on Friday
digging its way into the SW conus. Center of low pressure system
tracks to our northwest and warm front passes through the CWA on
Sunday afternoon. Adjusted threshold for all snow down to get all
rain in the forecast. Strong low level warm air advection warm temps
near the surface to above freezing at the onset of precip. Heavy
rain likely Sunday night into Monday as the main plume of moisture
passes through the area which may lead to flooding concerns due to
snow melt and frozen ground. At this time strongest forcing remains
to our west but a shift east with the storm track is still possible.

Better idea of the storm track once the system moves onshore and
can be sampled better.

Colder air gets wrapped around the low pressure as it exits to our
north which will transition rain into a snow with a possible lake
enhancement late Monday. Chance of some lake effect snow into mid
next week.|

Aviation (for the 06z tafs through 06z Thursday night)
issued at 1143 pm est Wed jan 17 2018
vfr with fairly vigorous wsw flow expected through the period in
between sfc ridge dropping into the deep south and a weak northern
stream traversing the northern lakes. Continued with long duration
llws group given limited mixing at the sfc.VFR otherwise with
only some mid-high level cloudiness anticipated.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
