Synopsis
Next upper trough and cold front move in Monday night, with a
stronger upper trough on Tuesday. Another cold shot arrives late
next week.

Near term through today
As of 1220 am Monday... Forecast remains on track and no changes
are needed at this time.

As of 530 pm Sunday...

no changes necessary.

As of 155 pm Sunday...

upper level pattern remains active with the closed upper level
low anchored over the hudson bay area. Another vort MAX within
the flow aloft will drop in from the great lakes over the next
few hours. Sensible weather impacts will be more low mid level
cloud cover that will bring flurries and low end chances for
measurable precipitation over the northeast mountains later
tonight after 05z. Flow then flattens out Monday ahead of the
next system which brings a clipper system in for the short term
period. For the most part, with the exception of the
aforementioned northeast mountains tonight, the near term
forecast is dry.

Warm front aloft brings a tight temperature gradient and
increase in 850hpa temperatures Monday, so should see a recovery
in the temperatures across the southern and western zones to
mid 40s.

Short term tonight through Wednesday night
As of 245 pm Sunday...

clipper digs south into great lakes with strengthening area of
low pressure at the surface. Associated cold front will move
across Monday night and Tuesday with cold air advection taking
place through the short term period.

Vigorous 85h thermal trough moves across in wake of front
passage. Models in general agreement that enough lift and
dendritic growth zone will be in place to allow for a decent
mountain snow event Tuesday into Wednesday. Bumped snow amounts
up slightly for the eastern mountains, while leaving lighter
snow amounts for the low lands. Expect to see some advisories
needed for the eastern mountains as timeframe approaches for
favored upslope areas. Surface gradients will be in place
Wednesday morning for near or below zero wind chill values over
the mountains. Other areas should see calm enough morning winds
in a decoupled nocturnal boundary layer where wind chill will
not be much concern. Thermal trough axis begins to shift
eastward late Wednesday. Trimmed MAX and min temp values from
model blends, keeping closer values with the inherited forecast.

Long term Thursday through Sunday
As of 245 pm Sunday...

upper trough swings east with forecast guidance diverging after
the middle of the week. In long term period made minimal
adjustments to the model blend for days 5 through 7. Any precip
we do receive this time period will likely be all snow as the
models at least agree that the cold air remains in place through
the end of the week.

Aviation 06z Monday through Friday
As of 1225 am Monday...

expectingVFR through the TAF period, but there will be someVFR
ceilings in the 4k to 5k feet range as a weak system passes
across the north. Cold front will be approaching late Monday
night into Tuesday morning, however, any restrictions should be
after 06z Tuesday.

Forecast confidence and alternate scenarios through 06z Tuesday...

forecast confidence: high.

Alternate scenarios: ceilings overnight could come close to MVFR
at ckb, ekn, or pkb.

Experimental table of flight category objectively shows consistency
of WFO forecast to available model information:
h = high: TAF consistent with all models or all but one model.

M = medium: TAF has varying level of consistency with models.

L = low: TAF inconsistent with all models or all but one model.

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.
