Synopsis
Issued at 1241 am est Wed jan 24 2018
cool and mainly cloudy conditions will persist into tonight and
Wednesday. A few snow showers or flurries will also remain
possible. Thursday into Friday will feature a nice moderating
trend with highs possibly exceeding 50 degrees Friday. This will
be followed by rain chances Saturday and cooler conditions Sunday
into early next week.

Short term (this evening through Wednesday)
issued at 210 pm est Tue jan 23 2018
lingering moist cyclonic flow in the low levels will keep clouds and
perhaps a few flurries around into tonight. Models do suggest some
lake enhancement in wnw flow which could result in slightly more
organized snow shower activity into NW in and SW mi. However,
coverage chances appear limited by marginal 10-12c delta t's and
bulk of moisture below the -10c level. This potential lack of
ice crystal formation could result in some drizzle or just
dry cloudy cool conditions.

A shortwave swinging through in wnw flow will help sustain thermal
troughing and mostly cloudy conditions tomorrow. Good mid-upper
level q-vector convergence noted in model land with this feature,
though lacking moisture should limit any precipitation to flurries
at best.

Long term (Wednesday night through Tuesday)
issued at 210 pm est Tue jan 23 2018
the second half of the work week will feature a nice moderating
trend and dry conditions as the next upper ridge builds over eastern
noam in progressive pacific dominate pattern. Low level ridge over
the area Wednesday will shift off to the east Thursday with
southwest flow really deepening strengthening into Friday. This
will allow for a breezy Friday and the potential for temps to
overachieve.

The next pacific origin upper trough and its associated cold front
will progress through this weekend with renewed chances for rain
showers on Saturday... Followed by cooler seasonable drier conditions
Sunday into early next week.

Aviation (for the 06z tafs through 06z Wednesday night)
issued at 1241 am est Wed jan 24 2018
MVFR conditions will continue through much of the period, with an
inversion and cyclonic flow. As mentioned in previous discussion,
we'll continue to hover around the 2kft landing minimum criteria
through at least the first portion of the TAF period. A shortwave
moving through will bring chances for snow showers, which are more
likely to start around 15z and continue through 21z, enhanced
perhaps by the daytime heating tomorrow. However, ceilings will
likely trend towards bkn015 starting around 9z, if they don't fall
lower before then. For now, kept things right around bkn020, but
wouldn't be shocked to see them drop below for a bit before 9z.

Otherwise, expect improvement toVFR by Wednesday evening.

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.
