Synopsis
Issued at 218 am est Fri nov 16 2018
cloudy and breezy conditions are expected today with highs in the
upper 30s to low 40s. A stalling frontal boundary will bring
chances for light snow and light rain this weekend. Highs each day
will reach the mid to upper 30s, with lows ranging between the mid
20s and low 30s. Next week will feature mainly dry conditions with
below normal temperatures early in the week trending warmer by
thanksgiving.

Short term (today)
issued at 218 am est Fri nov 16 2018
a trailing vort MAX within a larger scale trough axis will swing
east through the central great lakes this morning. Snow
showers flurries accompanying this feature may clip areas north of
us 30, though chances for measurable pcpn remain low given lacking
moisture depth and northward bypass of better forcing. Little to no
snow accumulation impact is anticipated as a result. Dry otherwise
as post wave subsidence quickly builds in, though it will be breezy
with slight warming aloft and a weak lake response in cyclonic flow
likely trapping a low cloud deck in for most of the day.

Long term (tonight through Thursday)
issued at 218 am est Fri nov 16 2018
temps will remain well below normal normal through the middle of the
next week, though some warming closer to normal expected by Thursday-
Friday as this unseasonably cold weather pattern finally breaks down.

As for precip chances, the main focus will be on a low-mid level
baroclinic zone expected to sag south into the local area this
weekend. The first sheared wnw flow upper wave and associated
frontogenetical response does look to clip our far northern zones
late Friday night through early Saturday afternoon with a period of
light snow. Chances for precipitation then diminish with the front
with time Saturday as the frontal circulation undergoes
frontolysis in wake of the dampening upper wave. Weak height falls
and right entrance upper jet support with a second mid level
trough axis then likely re-focuses a narrow band of precipitation
(mainly snow per latest model consensus) later Saturday night
into Sunday... With latest guidance suggesting southern and eastern
portions of the forecast area for pops light QPF during this
time. Overall impacts snow accums with each wave should be minor.

Mainly dry into next week otherwise.

Aviation (for the 06z tafs through 06z Friday night)
issued at 1145 pm est Thu nov 15 2018
lead SW responsible for this mornings mess wrapping through cntrl pa
ahead of upstream secondary kicker pushing through swrn wi. This sys
will cross the WRN lakes with little fanfare given subsidence
moisture void left behind in wake of lead wave. That said ifr based
cloud CIGS are locked in for the duration with stout thermal
inversion aloft.

In... None.

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.
